> Will these “guerilla solar” units that plug into a receptacle to back-feed get approved for use?

They are approved at up to 600 Watts in Germany, and that will probably get increased to 800 Watts soon. You can just plug the inverter output into an outlet. This is called "balcony power plants" here, and lots of municipalties are subsidizing it currently. You can't get net metering, but you can offset some of your load with minimal cost and paperwork.

When you define the market as electric vehicles instead of passenger vehicles. In Europe, the electric vehicle market is growing very fast.

But all these EV sales come at the expense of gas/diesel sales, so I think it is a bad idea to consider EV's as a separate market.

I think the only thing the market has going for it, is that everything else is worse.

Interest rates are negative or near zero, so bonds have the risk of losing value as interest rates rise, as the Fed needs to fight inflation. They also have no real upside, since interest rates are so low.

The Fed has agreed to print unlimited money to prop up businesses that basically don't exist, so having a bunch of cash is not safe, since the Fed is printing so much more of it.

So grossly overvalued stocks may be the best thing now.

Imagine how much simpler a commercial charging station is than a gas station. You already need electricity for a gas station, but you no longer need to send tanker trucks out to fill tanks and technicians to maintain all the mechanical pumps, or even the auditors who make sure that the pump is measuring gallons correctly.

It will be really easy to enable long distance travel for EV's that can DC fast charge. Charging for your home area is covered by wherever you park it.

Seems like a gas station death spiral is inevitable, once there is a solid travel network in place and ample 200 mile range EV's available.

> Chevy shipped a few hundred more Bolts than Teslas one month

In the US only (majority of Teslas sold oversees in October, as is always the case in the first month of each quarter).

Re:Tesla's head of battery engineering exits on Monday November 06, 2017 @06:22PM (#15639872)
For the US only. Tesla generally ships most cars oversees on the first month of the quarter and loads up in the US in the last month of each quarter.
Yes, I would have seriously considered the new Leaf, since it is about $5k cheaper than the Model 3. It would effectively cost $18k in Colorado vs $23k for the Model 3.

It would be nice to have the Nissan service and manufacturing capability behind the product. But since it is still designed to degrade, I won't consider it.

Tesla actively cools its batteries and chose a long lasting battery chemistry. The Leaf, does not cool the battery, and the early Leaf model had a really bad chemistry.
I wouldn't compare the Leaf, which has no thermal management system with a Bolt, which does.

The Leafs are basically designed to degrade. Tesla's and Bolts are designed to last.

Well, you said this was a dangerous plan. The biggest danger is that you have to go back to work.

If you continually only withdraw 4% of your nest egg (reducing your absolute withdrawal during market drops), then make up the difference if you need to in order to cover current expenses, then you'd be just fine.

Re:Interview with Mr. Money Mustache on Wednesday September 27, 2017 @01:01PM (#15349811)
Or god forbid, you work a little bit to supplement your nest egg during those 43 years.

It is interesting also to see financially independent people who are happy to rent, keeping their assets in more lucrative and flexible investments than the real estate they live in.

There are lots of reasons to rent. It is generally a mutually beneficial relationship, like pretty much every other business transaction.

If you could drive into Florida and sell bottles of water for $5, people will do it.

Same with gasoline. Price signals work.

I can write sort algorithms that are nlog(n) or n^2. Both pass functional tests.

I can write code that reinvents the wheel, instead of using the solid library I've never heard of.

I can do things in non-idiomatic ways that testing and linting will never catch.

All patents are open.

Tesla offered to share them with other auto OEMs, if they sign up to agree to Tesla's terms.

Re:Generate energy with kites on Monday August 07, 2017 @01:31PM (#14949314)
Good video. They said costs could one day get down to $50 per MWh.

We already have solar plants selling at around $30 per MWh, so that doesn't seem like it will be a major source, although it has the potential to run all day and all night, unlike solar.

Exactly right. Coal mining as a job has declined much more than coal as fuel. It's just easier to blame regulations and outsourcing than to admit that people can't compete with machines in energy production and manufacturing.
Too geography dependent, and we will probably never build another large hydro project because of the environmental impacts.
Commercial and Residential solar are excluded. Those might add up to half a percent or so. The other 9.5% is probably due to energy efficiency.

Solar panels have a warranty for 25 or 30 years. Their output slowly deteriorates over time, but there are 50 year old panels that still work fine out there.
I haven't experienced it, but I've only had a couple interviews/jobs as an electrical engineer before switching to software, where they happen almost every time.

I think it's a sign that universities are failing to be trusted as credentialing institutions. You should be able to verify a degree and conclude from that the person learned the material.

I guess this is why the professional engineering exams exist.

It's about the possibility of having your visa granted, not whether you need one. Perhaps you have heard about the travel ban in the US?
Is lithium the most expensive material in the chemistry?
That makes sense... Li is typically 4% of the weight of a Li-Ion battery, so that would align pretty well.
Re:Why taxing robots is not a good idea on Friday February 24, 2017 @09:31AM (#13723912)
Bill Gates really amazes me with his lack of vision. He thinks renewables are not a solution to sustainable energy and taxing robots makes sense.

Bill,automating physical labor is not the issue, it's automating driving and white collar jobs that's really going to disrupt society. It should be a tax on the computer, not the robot, if you think taxing progress is a smart idea.
