Aluminum-air batteries have eight times the energy density of lithium-ion.
 
My phone showed me a Daily Mail article about a British engineer that designed these batteries, but I don't know how good a source the Daily Mail is, and they use their words weirdly. Here's an article explaining how he developed this technology 18 years ago, but nobody in England would pay attention. France felt it was their nation's best interest to support him, but after two years, England convinced him to come back, only to waste his time. They say that he cannot get anywhere because everyone is obsessed with lithium. It sounds like this is a completely different type of battery, the aluminum is consumed in the process, although still reusable. It cannot be recharge, you would swap batteries after fifteen hundred miles! https://techcrunch.com/2019/07/12/na...metalectrique/

The spent batt aluminum would be reprocessed as aluminum ore.

I suppose that's grammatical. :)

If you don't trust the Daily Fail, how about TechCrunch?

Think of an air-breathing battery which uses aluminum as a “fuel.” That means it can provide vehicle power with energy originating from clean sources (hydro, geothermal, nuclear etc.). These are the power sources for most aluminum smelters all over the world. The only waste product is aluminum hydroxide and this can be returned to the smelter as the feedstock for — guess what? — making more aluminum! This cycle is therefore highly sustainable and separate from the oil industry. You could even recycle aluminum cans and use them to make batteries.

That TechCrunch article was good enough for me to use in #1, partially because it used American English [simplified].

Oopsie! :)

"A battery stores energy, a generator makes energy. These produce energy at a constant rate."--reddit, talking about radioactive diamonds.

Anyway, would a better title be "Aluminum-air generators?" :)

Also, according to that discussion, bananas are radioactive! How radioactive is the sun, compared to the average banana?

Banana for scale! https://i.imgur.com/3Lm6SDj.png

Today's fortune cookie "If at first you don't succeed, you are running about average.".

Yes bananas are radioactive.
Granite counter tops, concrete, stucco and the sun put off ionizing radiation.
The sun is radio active enough so that had people been on Mars in 2017 when the last intense solar storm hit Mars they would have been dead from radiation poisoning by about 7x what they needed to be just barely dead.
