High-end 15" laptops already have 100Wh batteries, and 100Wh is the practical maximum. So abandoning LPDDR would lead to a reduction in battery life on the high end, which probably isn't going to fly.

> isn't going to fly.

Literally - 100Wh batteries are maximum you can take on planes

In US, on non international flights, you can take 160wh ones if they are replaceable.

Strangely, the rule comes from ICAO.

Some countries too follow the 160wh standard, but most airlines simply don't bother enforcing anything, but the lowest common denominator.

I promise that was an unintentional pun. But yeah, that's the limiting factor.

> a 100WH battery

a hand grenade typically releases 250kJ, or about 70Wh

you're asking for the equivalent of 1.5 grenades in your lap :)

A chocolate tablet typically stores 4000kJ of energy. Yes that's 15 hand grenades, what are we waiting for: ban chocolate tablets now!

And don't get me started on flour, not only it stores a ton of energy (50 grenades per kg) but it's also highly explosive! [1]

[1]: (only with the right air to flour ratio of course, but accident happen every once in a while: https://www.grupa-wolff.com/a-tragic-flour-explosion/)

The chocolate bar doesn't start a violent fire if pierced. If it would we could power our laptops with chocolate :)

The flour conditions of exploding are far more difficult to achieve than a LiIon battery conditions - orders of magnitude difference.

Neither does a NiMH battery. There's no link between vulnerability to external damage and ability to power a laptop.

In fact, there's no fundamental reason why we couldn't run our laptop on chocolate[1], just that it's very far away from current technology.

I read Lion battery (lion as in the chocolate bar) and couldn't help but find it hilarious

It’s just that modern laptops run on Li-ion batteries.

True, but not that hard. I had some “dangerous experiments for kids” book back in the day and by far the most fun thing in it was aerosolizing flour with a straw to get the right mixture near your Bunsen burner for your own glorious short lived fireball.

In a world, somewhere, Flowers and Lions power laptops.

1.5 hand granades worth of LOW VOLTAGE ELECTRIC energy released into A CIRCUIT over A DAY or more and protected by multiple safety cut-off circuits with thermal and other sensors.

vs

A grenade releasing that as KINETIC energy into YOUR FACE over the span of LESS THAN A MILLISECOND and protected by a spring and a keychain ring.

Even if a lithium battery of that size experienced a critical failure right in your lap, you'd get away with a few scars and some serious but treatable burns. And I've only heard of one commercial product in the last 15 years that had serial critical battery failures...

Airlines tend to cap lithium-ion batteries at 100Wh, so it’s quite common for laptops and power banks to go to or just shy of that. https://www.apple.com/newsroom/2019/11/apple-introduces-16-i... speaks of a 100Wh battery. My latest laptop has about a 90Wh battery.

Hopefully your laptop and hand grenade have radically different power discharge profiles.

> Hopefully your laptop and hand grenade have radically different power discharge profiles

Li battery fires are not unheard of, unfortunately, so the profiles may start to resemble sometimes.

Lithium batteries burn, quite quickly but it still takes a few seconds, that can be pretty dangerous indeed but that's several orders of magnitude slower than a grenade.

There's a subtle difference. One is designed to release that energy in a fraction of a second in a frangible metal casing, the other is designed to release it over a number of hours. Yes, batteries can go wrong, just like any tech, but comparing them to hand grenades is just ludicrous.

> comparing them to hand grenades is just ludicrous

Next, let's calculate the energy input required to heat a small cup of coffee and compare that to a hand grenade. (Hint: The coffee wins easily.) I wonder how many hand grenade equivalents a 10 minute lukewarm shower equates to?

In some universe there's an internal combustion shower powered entirely by an operator ripping out pull rings with their teeth and throwing armed grenades into a heating chamber.

Preferably yelling 'fire in the hole!' each time.

To keep your peace of mind, refrain from looking up the energy content of a pizza!

Is it any worse than having 0.75 of a hand grenade on your lap? If it starts to smoke, you throw it away all the same. Besides, this capacity is standard in larger laptops, but not in smaller ones for some strange reason.

> If it starts to smoke, you throw it away all the same.

No. If it starts to smoke, you commit & push --force, then you throw it away.

You can save a couple seconds with git-fire.

The hand grenade is arguably better at releasing that energy at an instant.
