I’m surprised there hasn’t been more development of engines optimized as range extenders. That seemed like an obvious next step from the Prius, for example.

But I think the peak of that opportunity has passed. The market in Europe and China is going to flip to pure electric in 5-8 years, with the US 5 years later. The window for developing new models that fit into that transition is shrinking. There will be long term demand for range extended vehicles, still in 15 or 20 years, but it will be niche.

>The market in Europe and China is going to flip to pure electric in 5-8 years

That's way too optimistic for Europe. Maybe with the exception of Norway and Europe's largest metros like London, most of Europe will stay on ICE for a long time.

The price of electric cars here is too high for most incomes and the cheaper ones have too little range compared to ICEs. Not to mention the charging infrastructure is still lacking.

Right now they're still toys for the rich man with a house and not tools for the average joe.

I'd rather we invest the money in public transport and cycling infrastructure to rid the cities of cars but unfortunately the auto industry lobbies too strong in Europe for that to happen.

Still no one can answer the question of where do you charge one if you rent an apartment with no parking or a terraced house with no driveway. Don't get me wrong, I'm planning to go 100% electric in the next few years, but then we're lucky enough to have a house with a double driveway - I have no idea how it can possibly work for people without dedicated parking.

You'll need cities to do large scale deployments of streetlight chargers like these: https://electrek.co/2019/11/13/la-adds-hundreds-of-ev-charge...

I don't know if it'll require upgrades to the power grid. You've already got 240v in Europe, so that's only ~10 hours to charge a Tesla. But could it handle thousands of EVs charging simultaneously?

If there's any place in the world that can do this it's Europe.

Re:New two-stroke engine design could help keep internal com... by gambiting on Tuesday May 26, 2020 @11:16AM (#23312186)
I still don't think that this will be anywhere enough. This is a street I used to live on: https://www.google.pl/maps/@54.9941128,-1.6077652,3a,75y,286...

From top to bottom, it would fit about 40 cars - but there's only 6-8 street lamps? Ok, so maybe the council could fit a new charging post every 10 metres or so - but then the question is, with what money? There's hardly any cash to keep maintaining the roads at all, where would they find the money to dig up every single street in the city and put in charging posts? Even if they are paid, you'd wait a very long time to make your money back, and then there's another issue I have - at home, I can charge my car at about £0.12/kWh during the day and £0.05/kWh during the night. But public charging points I can see around at crazy expensive - like £0.30-£0.40 per kWh. At that point, it's literally cheaper to drive a good diesel.

Re:New two-stroke engine design could help keep internal com... by AnthonyMouse on Tuesday May 26, 2020 @01:16PM (#23313774)
The key to this is you don't build too many of them.

The wires aren't the problem; you've already got a power grid carrying kilovolts along the same streets to power the buildings. The cost is the charging ports. So start with one, reserve the space for EVs and make it expensive.

Then people won't want to use it. Most of the time they'll charge at work or some restaurant that installed a charging port to drive customers to its business. Which is why you only have to start with one -- the first one on the street is just for emergencies. You might have ten EVs in the area and one charging port because at any given time only one person is willing to pay that much to use it. Which also means that it's regularly in use and can recover its costs quickly. But then it's there if you really need it, so more people can feel comfortable buying EVs.

Then once there are more EVs, you can install more charging ports -- they're paying for themselves, after all, as long as you don't install so many they don't stay in use.

Then once you've paid off the capital cost you can lower the price, so more people use them, so you can build even more. When you have 10 charging ports but 9 are already paid off, you only have to charge 10% of the original premium to pay off the 10th. So in the long term you still end up with plenty of charging ports on the street at only a slightly higher price than they are in other places.

The best thing would be to make them expensive when the vehicle is >70% charged so it incentivizes drivers to free the charger equipped parking spot when the vehicles is full of almost full. That way the charger becomes available to others.
Re:New two-stroke engine design could help keep internal com... by ChuckNorris89 on Tuesday May 26, 2020 @12:06PM (#23312885)
1000x this! People never stop to ask themselves who will pay for the infrastructure needed to upgrade the existing public electrical networks in our cities to support everyone charging their EVs on the street.

Lots of European cities are broke at this point and have much bigger problems to fix right now than EV charging stations and if private companies would install them across the cities, the charging costs would be high enough to make EVs ownership unappealing.

Add the fact that EVs here are more expensive than in the US and you have the reason why most EVs right now are only owned by upper class people who can afford to have their own private charging station on their own property.

There's a reason diesel ICEs, as dirty as they are, are still so popular in Europe. They're cheap to run.

Ironically, as green as it may be, Europe will fall behind China and the US at mass EV adoption.

Unless they'd be given away for free, expecting EVs to take over the market here in 5 to 8 years is dreaming at best.

Western Europe will do it as means to incentivize auto sales after the pandemic. Car sales fell 80% in Europe. President Macron has already announced such a plan yesterday. This includes infrastructure:

"The number of battery charge-points will be tripled to 100,000 by the end of next year."

These European city planners should have listened to Strongtowns and other New Urbanists, and instead of encouraging suburban development style which makes prohibitively expensive for cities to maintain streets, instead followed the dense urban pattern of American cities.

Rest assured it will, and not only on the power grid.

Back of the envelope calculation.

A modern lamp post (one every 30 mt or so) is (led based) 60-80-100W, if infrastructure (cables) are not so recent, previous generation of street lightning were 150-250W per post.

Cables are dimensioned accurately to carry that kind of current/power.

A charging every 30 mt needs to serve 6-7 cars, we are talking of 7-10KW, i.e. 7000-10000 W, something like 40 times the power the infrastructure was designed for.

And each 300 mt stretch of street will need something in the order of magnitude of 70-100KW, and since all cars will be charged at night, there are very little to be spared for non-contemporaneus power usage.

Our city had to ban cords running across the sidewalk after too many slip and fall incidents.

In areas where the street lights are set onto the property side of the sidewalk (or even into lawns) rather than on the sidewalk abutting the street (most NA residential areas I think) I don't see this idea gaining a lot of traction. Or at least not remaining for long past the sidewalk turning into an obstacle course for the elderly and others with limited movement.

> Still no one can answer the question of where do you charge one if you rent an apartment with no parking or a terraced house with no driveway.

The first customers are people who can install a charging port where they normally park their car. That's probably more than half of car owners, and gets you to at least a double digit percentage of cars as electric.

At that point there are enough electric cars that a charger starts getting installed anywhere there's a lot of parking. Then more people can buy EVs, and do, so more chargers get installed. By the time most cars are electric they'll be everywhere.

Charging at home or at work is best with electrics, but the gas station model is still possible. With a range of 500-600km and high power charging at 1000-1500kph, which is all being done right now, you can go somewhere and charge once or twice a week. It's not quite as convenient at 20-30 minutes, but it's possible; when combined with some sort of destination, like a grocery store, it's more time-efficient.
Re:New two-stroke engine design could help keep internal com... by gambiting on Tuesday May 26, 2020 @12:34PM (#23313218)
Yes, except that as I pointed out in my other comment - public stations around me charge about £0.30-£0.40 per kWh(and I know that rapid stations near motorways charge even more) - at that price, it's literally cheaper to drive a diesel. Yes, we can make an argument that once people have no choice, they will pay that money to charge anyway. But privately-owned infrastructure has no reason to be free or cheap, except for the very initial period when say shopping centres are trying to attract EV drivers. Once they are essential infrastructure it's hard to see them being cheap.
Re:New two-stroke engine design could help keep internal com... by xyzzyz on Tuesday May 26, 2020 @01:27PM (#23313945)
Privately owned infrastructure has good reason to be cheap, that is, competition from of their privately owned businesses. Food distribution network is much more essential than EV charging, and yet food is now cheaper than ever. What matters is not how essential something is, but rather at what cost the service can be provided. If a charging station can expect many customers use it, which will quickly amortize the capital costs of construction, you’ll see charging prices at those stations go not much higher than the operational costs. Otherwise, if the prices are high, this incentivizes new businesses to enter the market and undercut existing producers.

Lots of essential infrastructure is cheap because of competition, like for example electricity generation. There is no reason to believe EV charging will be different.

Of course, it might also turn out that while electricity costs are low, other costs of running charging business are high. If that’s the case, that doesn’t bode well for EV adoption in among people who don’t live in houses.

I've been reading HN for years and people from the USA keep writing that this didn't happen there for fiber and other telecommunication service. Is it going to happen for EV chargers?

Re:New two-stroke engine design could help keep internal com... by xyzzyz on Tuesday May 26, 2020 @02:48PM (#23314969)
US actually has pretty good fiber penetration and internet speeds now (it used to be quite a bit worse a few years ago). The biggest difference between fiber and EV chargers however is that fiber only makes economic sense if you have extensive network, while EV charges can be installed locally by smaller entities. Additionally, installing electric equipment is easier than digging up whole towns, because you don’t need as much political buy-in, less permitting is necessary etc.

>>There is no reason to believe EV charging will be different.

This is exactly what I'm saying though - motorway petrol stations are insanely expensive, because they have no competition - a company wins a contract to run the only petrol station on a given stretch of the A1, so they can charge obscene prices for petrol. Same is already happening with electricity - some providers along motorways charge an insane £0.69 per kWh, it would be cheaper to fill up another car with premium unleaded and use it to charge the electric car at that point.

Re:New two-stroke engine design could help keep internal com... by AnthonyMouse on Tuesday May 26, 2020 @01:27PM (#23313929)
Why would you you expect shopping centers to stop wanting to attract EV drivers? It's practically their dream to have everybody wandering around in the mall for an hour or more with nothing better to do than buy stuff because they're waiting for their car to charge.

Still surprising how members of this website are still mostly blind to the obviousness of fuel cell cars. Just turn that excess electricity from renewables and convert it to hydrogen, powering a fleet of hydrogen powered vehicles. Solves all infrastructure issues being brought up. Furthermore, it's possible to power large vehicles like semi-trucks or ships, even aircraft at some point in the future.
Re:New two-stroke engine design could help keep internal com... by gambiting on Wednesday May 27, 2020 @03:54AM (#23320535)
On the other hand, I'm constantly surprised how anyone anywhere still thinks that fuel cell cars are a good idea.

There is zero elemental hydrogen on Earth. 99% of the one we use is a byproduct of fossil fuel industry. Yes, you can produce it from electrolysis, but not only the hydrogen produced this way will never "break even" it's actually much worse than "even" since you then need to spend a whole load of energy to compress it and bottle it. Why not...just put the electricity into the existing grid and charge automotive batteries directly? After all, fuel cell cars are electric cars, direct combustion of hydrogen was experimental and extremely inefficient.

That brings me to my next point - hydrogen has the smallest molecule of all, which means that it evaporates naturally through any container you put it in. 70kg lead bottle only holds 1L of hydrogen, and it naturally loses all of it in 2-3 weeks. So no underground carparks, garages etc because of the explosion risks.

But finally - there is no infrastructure for hydrogen. It's like trying to build a network of petrol stations....from scratch.

And batteries are definitely good enough to power larger trucks, it's just the cost that's prohibitive(enough cells for a large semi would cost many times more than the truck itself).

Re:New two-stroke engine design could help keep internal com... by Hypx on Wednesday May 27, 2020 @05:03AM (#23320970)
I must inform you that you're mostly spreading ignorance or obsolete information with claims like those. Most of the claims you're making are either wrong or many years out of date.

> There is zero elemental hydrogen on Earth.

Not actually true. As I understand it, reserves of natural hydrogen do exist underground, similar to how helium is sometimes trapped underground in certain formations. These could potentially be huge source of hydrogen, although right now it's just speculation.

> Yes, you can produce it from electrolysis, but not only the hydrogen produced this way will never "break even" it's actually much worse than "even" since you then need to spend a whole load of energy to compress it and bottle it.

Since we live in a world of zero priced, and sometimes negatively priced renewable electricity, this is a non-issue. In fact, it's irrelevant. The biggest motivation for green hydrogen right now is the fact that we have far more green energy that we can use for large stretches of time on the grid. We're currently "curtailing" that electricity, which is a fancy word meaning that we're throwing it away. Turning what is in effect a waste product into a valuable new fuel is a big gain.

> Why not...just put the electricity into the existing grid and charge automotive batteries directly? After all, fuel cell cars are electric cars, direct combustion of hydrogen was experimental and extremely inefficient.

Largely because we can't match production with demand. As I mentioned above, we have huge surpluses during parts of the day, but also we have huge shortages at other times. Using hydrogen as a load balancer is an excellent idea right now. We can do this to a certain extent using batteries or pumped water, but we quickly run into the limits of these technologies. Hydrogen can be stored in far larger quantities than any battery in the form of underground salt caverns.

> That brings me to my next point - hydrogen has the smallest molecule of all, which means that it evaporates naturally through any container you put it in. 70kg lead bottle only holds 1L of hydrogen, and it naturally loses all of it in 2-3 weeks. So no underground carparks, garages etc because of the explosion risks.

Carbon fiber tanks have long since solved this problem. We know this since you can buy FCEVs right now, and they are perfectly fine vehicle with none of the above issues. Indeed, I've seen quite a few hydrogen skeptics review these cars, and while they maintain their skepticism of the idea of hydrogen, they seem to be at a loss at describing any kind of real shortcoming in the technology itself.

> But finally - there is no infrastructure for hydrogen. It's like trying to build a network of petrol stations....from scratch.

This is changing. There are now hundreds of hydrogen refuel stations around the world, and many more being built. This is particularly true in Asia, where governments in that region have sponsored huge hydrogen infrastructure buildouts.

> And batteries are definitely good enough to power larger trucks, it's just the cost that's prohibitive(enough cells for a large semi would cost many times more than the truck itself).

There many problems with battery powered semi-trucks. Cost is one of them, and weight is another big one. Furthermore, recharging them in a few minutes is a huge selling point, and batteries cannot deliver on that need. FCEVs are a much better answer for long-haul trucking than BEVs.

Sure, but this simply doesn't exist. It's Sci-Fi at this point. A lot of countries are planning a complete ban on petrol/diesel new cars within 10-20 years, yet there are no such signs of such systems(and I suspect there won't be, since every single manufacturer uses different batteries of different shapes and sizes, in some EVs the batteries are simply not removable without hours of work first). Doing this would require standardization, and seeing as we're still in the early innovation phase, that would practically be suicide for the tech.

You charge at charging stations that are nearby where you live, just like people do with gas stations now.

You can charge while you get groceries (or a haircut, or dinner, or whatever) and then go on with your day. Certainly not as convenient as charging at home, but not impossible.

Electric cars are going to become extremely compelling very soon. A 300 mile electric car is close to the same cost as an IC engine over it’s lifespan. But, where IC engines have a hundred years of development and economies of scale electric cars are getting significantly better very quickly.

Charge infrastructure is expanding rapidly due to current rates of adoption which further makes electric cars more appealing every year.

Re:New two-stroke engine design could help keep internal com... by Unklejoe on Tuesday May 26, 2020 @09:10AM (#23310664)
While electric cars will cost less over their lifespan (due to much less maintenance), they still cost a lot more initially, and I think that's the biggest hurdle right now.

A lot of people can't drop $40k on a car, but they can spend $25k up front and another $15k over the life of the car.

I think the major changeover will be when I can buy the equivalent of a Honda Accord, but fully electric, and for the same price.

The Tesla Model 3 was supposed to be that, but in reality, it still costs more.

Re:New two-stroke engine design could help keep internal com... by aianus on Tuesday May 26, 2020 @09:39AM (#23310949)
Very few people spend $25k up front for a car. They lease it or finance it over 60 or 72 months.

Unless you’re referring to the psychological sticker shock only and not the actual cash flow implications.

Re:New two-stroke engine design could help keep internal com... by gsnedders on Tuesday May 26, 2020 @09:51AM (#23311082)
And that ignores the fact that the majority of car sales are not new cars, so the average purchase price of a car is lower still. Even once the majority of new car sales are EVs, we still have a long way to go (with both energy generation and the long period before the majority of miles driven are in EVs).

Not really in the market for one, but in the US the 2019 Hyundai Ioniq (range of ~120 mi, so not ideal if you don't have a charger at home) is $99/mo with $1000 down for a 3 year lease, which is dirt cheap. I'm guessing after three years the battery will still be valuable, so they can be aggressively pricing it this way.

I think if Tesla had better leasing, you'd see way more of them

Re:New two-stroke engine design could help keep internal com... by gambiting on Tuesday May 26, 2020 @10:23AM (#23311494)
I have no idea how the price is so low in the US then, that's insane. We looked at the Ioniq for my wife last year and it was something like £3000 upfront and then £400 a month for 4 years - it's just a lot of money. For comparison, you could have a brand new VW Polo for £1000 upfront and £200 a month - and there's absolutely no way she could use £200 worth of fuel every month, even if petrol doubled in price.

California has this concept of a “compliance car”. There’s a legal requirement to sell X electric cars, so the manufacturers practically give away small, cheap cars to enable their IC business.

Fiat-Chrysler did it with the 500e, and back in the day the big 3 did it with subsidized Cavaliers and Escorts.

What are you talking about? EU is tightening the screw on manufacturers so hard that they are literally panicking right now, as there is literally no way they can meet the regulations as is. Currently there is a requirement that fleet averages have to be below 100g/km for CO2, soon that falls down to 75g/km and then 50g/km - with every car sold above that threshold incurring heavy penalties. We're seeing literally every manufacturer rapidly moving towards hybrids and pure EVs, because there is no way to meet those targets otherwise - VW has completely axed all ICE versions of the Up(and their Skoda and Seat equivalents) going full electric, just to bring their averages down. Even Fiat, whose market was always low-end, cheapest of the cheap vehicles, axed ICE Fiat 500, and has gone full electric. Panda(!!!) is now a hybrid! Even Dacia, which is literally bottom-bin of cars, is introducing a hybrid and potentially a full EV soon.

All of this is only happening because of the pressure from EU regulators.

To see how these norms are effectively impossible to meet with ICEs, note that these translate to fuel efficiency of 4, 3, and 2 liters/100 km, or for American folks, 58, 78, and 117 mpg respectively.

€23.000 ID.3 vs €20.000 ICE Golf in Germany, from what I understand the Golf is one of the best selling cars in Europe. Also I believe many European countries exempt or greatly reduce emissions taxes on EVs, so that difference could probably be made up quickly.

An engines go back to at least the 1600’s with precursors all the way back into the first century AD. Except cars are really their own thing with their individual needs.

Electric cars are vastly more than just a battery and electric motor. Regenerative breaking, power distribution, heat management, possibly a simple transmission etc etc. The amount of innovation in this space dwarfs what’s happening in the IC space because the problems are so new.

Sort of. The core, kernel issue of fuel weight/kwh is still limiting electric.

I don’t think weight is much of an issue at this point. EV Acceleration in normal driving is fine and their range keeps going up. The new Roadster for example is aiming for a 200kWh battery and still has crazy acceleration. Cost seems like a bigger deal, but economies of scale are driving that down quickly.

EV’s hit 2.5% of total sales in 2019. 2020 is likely going to be odd, but scaling production still seems to be the bottleneck.

Re:New two-stroke engine design could help keep internal com... by JoeAltmaier on Tuesday May 26, 2020 @10:49AM (#23311844)
1 gallon of gas is 33kwh. And can be 'recharged' into a vehicle in 10 seconds.

So sure the Roadster can hold what, 6 gallons? Like an econo-box. And weighs 2 1/2 - 3 tons. Much of that in battery.

Yes, weight is still the big issue.

Re:New two-stroke engine design could help keep internal com... by Retric on Tuesday May 26, 2020 @10:53AM (#23311908)
An EC engine is a long way from 100% efficient. Model 3 Long Range is 310 mile range on a 75kWh battery. Cars are not hitting 310 miles on 2.3 gallons of fuel.

For the most extreme comparison, a Bugatti Chiron gets an EPA 11 MPG so the roadster is arguably the equivalent of a 56 gallon fuel tank where the Chiron is stuck with 26 gallons.

PS: A better comparison would be a similar ~200,000$ two seater but none of them are optimized for fuel efficiency.

> "And weighs 2 1/2 - 3 tons."

A bit of a tangent but it'll be interesting to see what effect an all electric vehicle future has on the design of roadways, bridges, etc. I imagine that many things will need to be rebuilt to handle the additional load.

Re:New two-stroke engine design could help keep internal com... by mikestew on Tuesday May 26, 2020 @12:46PM (#23313367)
They're already built for it. The '73 Pontiac Bonneville I rode around in as a kid weighed 4300 lbs. And as sibling comment mentions, anything not a car or light truck will outweigh anything with batteries. Our Sprinter-based RV weighs 10K lbs. empty, and it is a small RV.
Re:New two-stroke engine design could help keep internal com... by selectodude on Tuesday May 26, 2020 @12:31PM (#23313179)
They're already "designed" for 18-wheel trucks which weigh 15-20 times that. Even heavy EVs are nothing compared to heavy transport.
Re:New two-stroke engine design could help keep internal com... by ThrowawayR2 on Tuesday May 26, 2020 @12:39PM (#23313283)
To use your own example, they're designed to handle a certain quantity of 18 wheelers but they're not designed to handle traffic that is entirely composed of 18 wheelers.

Raising the average vehicle weight from 1.5 to 3 tons will definitely have an effect.

Re:New two-stroke engine design could help keep internal com... by selectodude on Tuesday May 26, 2020 @12:51PM (#23313430)
But not as much as it would seem, since road damage is a quadratic function of weight and one truck does as much damage as 9600 1 ton cars. Doubling the weight of the car would maybe narrow that by a few percentage points, but vehicle miles for any personal vehicle at essentially any weight is a rounding error compared to one truck.
Re:New two-stroke engine design could help keep internal com... by Retric on Tuesday May 26, 2020 @01:51PM (#23314246)
Bridges at least need to be designed for just 18 wheelers because over 50 years that’s going to happen at least once.
Re:New two-stroke engine design could help keep internal com... by war1025 on Tuesday May 26, 2020 @05:41PM (#23316747)
Roads are designed for a certain amount of "axle weight" [1] which basically means to carry a heavier load you need to add more axles to distribute the load.

I would guess electric cars are still negligible in that metric, though.

Where is 'here'?

Here in Australia the price of pure electric cars is way too high - and not helped by federal government (lack of) subsidies, tariffs, policy preferences for fossil fuel, lack of charging infrastructure, etc.

I recently scoped out comparable ICE vs full electric new vehicles, and 'around the same' quality/comfort/range/size we were looking at roughly 3.5x the cost for electric. A 5y cost projection for an ICE that does 4.5 litres / 100 km, even with anticipated (higher) servicing costs, doesn't get us to a compelling proposition.

Numbers for Portugal: In the last quarter of 2019, EVs (pure+hybrid) accounted for 4.6% of new vehicle sales, an 80% YoY increase. At these growth rates and start point, the 5-8 year estimate looks sound.
Re:New two-stroke engine design could help keep internal com... by ChuckNorris89 on Tuesday May 26, 2020 @09:11AM (#23310670)
The 4.6% you mention is not only small but also not useful here as it includes hybrids as well, not just pure EVs. Remove the hybrids and the number of pure EVs plummets

Let's face it, pure EV adoption is a lot slower than we'd like to and lying to ourselves about it doesn't help.

Re:New two-stroke engine design could help keep internal com... by sergiosgc on Tuesday May 26, 2020 @09:59AM (#23311176)
Hybrids are a gateway. I view them as in the same category as pure EVs, only "earlier technology". I own a hybrid, and I'm 90% sure my next car will be pure EV (3 years from now). I don't know any hybrid owner planning to ditch the electric motor on the next purchase, and know several planning to ditch the combustion engine on the next car.
Re:New two-stroke engine design could help keep internal com... by ChuckNorris89 on Tuesday May 26, 2020 @10:13AM (#23311342)
Yes, I agree with your point but this doesn't address your previous argument that a 4.6% market share in 2019 of hybrids and EVs combined out of which maybe 2% pure EV will result in a market dominance of pure EVs in 5 to 8 years. Such an exponential growth is no way possible in such a short time no matter how much you love EVs.

Hybrids are easy to justify buying as you don't depend on charging infrastructure or lack thereof but once you switch to pure EV that becomes your bottleneck which rules out drivers who don't have chargers available at their home or at work or who want to drive long distances on vacations with family or who don't have too much money to spend on a car.

Re:New two-stroke engine design could help keep internal com... by sergiosgc on Tuesday May 26, 2020 @12:49PM (#23313407)
I do not entirely disagree with you, I just don't have your certainty of the outcome. Predicting non-linear curves is next to impossible. A tiny movement in the beginning of the curve produces wildly different results. What I stated is different: 5-8 years for the market flipping towards EVs is _plausible_.

In other words, I can't prove with certainty that the market will flip, but I wouldn't bet on the contrary.

Re:New two-stroke engine design could help keep internal com... by mkl on Tuesday May 26, 2020 @08:55AM (#23310494)
Is there reason to expect exponential growth? Seems a bit doubtful to me. What was the YoY increase for other recent years? With linear growth, you'd be looking at 37 years with these growth rates and start point.
Re:New two-stroke engine design could help keep internal com... by CydeWeys on Tuesday May 26, 2020 @08:59AM (#23310535)
It caps out at 100%, so of course it's not going to be exponential growth. It is likely to be a logistic curve though, and we are still in the roughly exponential leftmost portion of it. Once there's mid-double-digit market penetration it's going to slow down a lot to roughly linear, then eventually, asymptotic.
Re:New two-stroke engine design could help keep internal com... by mkl on Tuesday May 26, 2020 @09:06AM (#23310608)
Yes, that's more what I'm picturing. That asymptotic phase makes 5-8 years seem unlikely unless a legal obstacle is introduced.
Re:New two-stroke engine design could help keep internal com... by maxdo on Tuesday May 26, 2020 @09:42AM (#23310978)
several battery breakthroughs that will dump the cost way bellow the holy grail of car batteries of $100/kwh that makes them on pair with ICE cars. Some estimates predict that they will go way bellow $80 in 2021-22, Means end of 2022 beginning of 2023 will be flooded with even cheaper comparing to Model 3 cars with better quality batteries. Good quality $25-30k electric car will be a new reality. Those segments attack bestsellers like Toyota Camry etc... I'm pretty sure the price war will push them even lower within 1-2 years. Means full line of EV's from very cheap to luxury by 2024-25 on a scale from multiple companies. As a result we will have cars on the market that cost the same, perform better, and cheaper in a lifetime from service and fuel perspective. Millennials and GenZ also very eco-friendly, which means younger people are eager to buy EV's. The only delay could be new battery terra-factories rollout lag. That might give an extra 1-3 years lifetime for ICE. After that the traditional car market will be shaking as never before.

Actually, they're more likely to prefer a car free lifestyle unless of course they have a six figure job in finance or at FAANG but that's like 1% of Millennials and GenZ in Europe, the rest are broke AF.

It has held at exponential growth for ~5 years. It can't be exponential, it has to be a sigmoid, but I'd expect similar growth rates for a few years more.

I should probably say in the process of flipping rather than have flipped over that time period, it’s not going to be 100% or 80%, but the s-curve transition will be well underway, and car manufacturers will have their hands full developing the technology.
Re:New two-stroke engine design could help keep internal com... by ashtonkem on Tuesday May 26, 2020 @10:43AM (#23311760)
The Prius is the wrong kind of hybrid for that, as the Prius is a parallel hybrid; both the electric and the ICE power train terminate in a planetary gear for shifting power around between the two power sources and the wheels.

What you're looking for is a series hybrid, like the Chevy Volt. In a series hybrid the only thing the ICE powertrain does is run a generator to keep the battery topped up. This allows the ICE to run in its ideal power band range permanently, reducing its size and making gasoline only travel much more efficient while lowering vehicle cost.

Re:New two-stroke engine design could help keep internal com... by cmrdporcupine on Tuesday May 26, 2020 @02:12PM (#23314502)
The Chevy Volt is not a series hybrid. It can operate like one, in some modes, but GM actually found, especially for Gen 2, that a mixture of series and parallel is most efficient.

When the Volt runs out of battery, it's almost not noticeable apart from engine noise. The performance characteristics in hybrid mode are almost identical to EV mode in terms of torque/acceleration.

It's an engineering marvel. I love mine. Shame GM killed it.

Re:New two-stroke engine design could help keep internal com... by labcomputer on Tuesday May 26, 2020 @12:02PM (#23312832)
The 1st generation Chevy Volt works (almost) the same way as a Prius, and does not normally operate the way you've described it. The 2nd gen is similar, but borrows some of the "2-mode hybrid" design from the 2008-2012 Chevy truck transmission (in order to have two gear ratios in electric mode--much more elegant than the Taycan).

Both have a planetary gearset with engine on one gear, output on another, and an electric motor on the third. The difference lies on which gear the second electric motor is placed (motor shaft on the Volt, output shaft on the Prius), as well as some additional clutches and brakes in the Volt.

Re:New two-stroke engine design could help keep internal com... by cmrdporcupine on Tuesday May 26, 2020 @02:13PM (#23314514)
And you'll find the Volt outperforms the i3 Rex in terms of hybrid efficiency and performance. When the i3 is in range extended mode it's pokey; and only meant to go a short distance before one gets a charge.
Re:New two-stroke engine design could help keep internal com... by ashtonkem on Tuesday May 26, 2020 @05:25PM (#23316590)
Is that a limitation of series hybrids, or is that a consequence of the engine used in these specific models? The gasoline engine in the 2nd generation volt has 3x the power of the one in the i3 (75kW vs 25kW).
Re:New two-stroke engine design could help keep internal com... by cmrdporcupine on Tuesday May 26, 2020 @05:43PM (#23316769)
Probably both? I do know that GM ended up going more "parallel" with Gen 2 than with Gen 1. And Gen 2 has more torque than Gen 1, despite switching to a lower displacement engine and going to an Atkinson (tuned for electricity generation) cycle.
Re:New two-stroke engine design could help keep internal com... by LeifCarrotson on Tuesday May 26, 2020 @02:14PM (#23314528)
Still, though, series hybrids like the Volt and BMW i3 just use regular inline-4 gas engines taken from their other production lines.

The Volt has basically the same engine as in the Chevy Sonic or Cruze, and the i3 range extender option uses the same engine as their C600 series scooters. Those engines are designed with a quick throttle response and a wide power band to operate over an RPM range sufficient to drive a vehicle through a regular transmission.

I don't doubt that for the same time and money, it was far better for GM and BMW to take advantage of the economies of scale around those products than to design an engine specifically to function as a range extender, but if they really took this as a core function or started from scratch I expect they might select a medium-speed industrial diesel engine instead: something optimized for a particular speed and power output that does that one thing optimally.

Re:New two-stroke engine design could help keep internal com... by cmrdporcupine on Tuesday May 26, 2020 @04:10PM (#23315856)
Again, completely untrue. A) Volt not a series hybrid B) the gas engine in Gen 2 Volt was not taken from their production line, it is an Atkinson Cycle engine designed for generators, not for their crappy ICE trucks and SUVs.

C'mon, can people research before opining?

"While it shares many parts with the new 1.5L I-4 used in other GM products, the Gen II engine’s combustion process and calibration are specific to the Volt. Its larger displacement not only improves fuel efficiency but also provides more torque, which contributes to the Gen II Volt’s surprising quietness."

I hope they customized the injection mapping, but the GM LUU engine is still a naturally aspirated gas engine with 10.5:1 compression and 73.4 x 82.6 mm bore/stroke ratio, measurements which primarily came from the ICE-only target applications it was designed for.

Or as an add-on trailer.

Tow your own generator.

Re:New two-stroke engine design could help keep internal com... by AnthonyMouse on Tuesday May 26, 2020 @12:38PM (#23313257)
That's a really good idea. You typically only need it on long trips, and then it can also be a normal trailer to load all your gear into. Meanwhile when you get to your trip destination, now you have a generator to run electrical devices without having to worry about running down the car's battery.

And it's normally at home, so if the power goes off for a week you can still run your house and charge your car.

Re:New two-stroke engine design could help keep internal com... by ajuc on Tuesday May 26, 2020 @05:50PM (#23316851)
You should just be able to rent the trailer if you need it a few times a year. Parking space for a trailer that you're never using is going to cost you too much in big cities.

You would need a 20-30kw generator+fast DC charger as the built it AC charger in most electric cars is not fast enough to maintain a charge at highway speeds (especially while towing something).

Like other commentators have mentioned, if a u-haul like network of these were made, if you ran out of charge somewhere, they could drop one of these off to get you going again, as a depleted battery pack will charge slowly, making the van full of batteries potentially more expensive (you would have to pay for an extra 15-30m of their time).

Re:New two-stroke engine design could help keep internal com... by wtallis on Tuesday May 26, 2020 @02:43PM (#23314892)
20-30kW might be a bit higher than needed unless the trailer is oversized to provide extra cargo capacity in addition to carrying the generator. You don't need a generator big enough to prevent the battery from draining at all; you just need to extend the range enough to cover a full day of driving while offsetting the extra drag from the trailer. 10-15kW is probably plenty for a trailer that only carries the generator: that would double the highway range of a Model S and would weigh about 700 lbs while being compact enough to have very little aerodynamic drag. A 30kW generator would be enough to double the range even if the trailer doubled the energy consumed per mile, and that's only going to happen with a pretty large trailer.
Re:New two-stroke engine design could help keep internal com... by extrapickles on Tuesday May 26, 2020 @07:03PM (#23317479)
The Model S is fairy efficient and aerodynamic compared to other EVs.

If anyone did this, they probably would offer 15kW and 30kW versions, so both passenger cars and light trucks would be covered.

Re:New two-stroke engine design could help keep internal com... by bigredhdl on Tuesday May 26, 2020 @12:02PM (#23312834)
Thats actually a pretty sweet idea. Only take the generator with you when you need it.
Re:New two-stroke engine design could help keep internal com... by TeMPOraL on Tuesday May 26, 2020 @12:50PM (#23313417)
Make them pluggable into the car (vs. towable) and standardize on the interface, and there could be market for renting the generators (like e.g. you do with city bikes - take them from one station, drop off on another).
Re:New two-stroke engine design could help keep internal com... by allannienhuis on Tuesday May 26, 2020 @03:47PM (#23315624)
Attach it to the tow hitch framework like a bike rack. :)

I suspect that would really mess with the load dynamics on most passenger type cars, as the generator would be pretty heavy. I don't think you'd be able to lift a big enough one into the trunk area, and attaching it to the back of the car would be a pain too. I think towing solves a lot of issues for the idea.
