Dont watch this at work unless you can spare 15 mins

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor

Interesting concept, I wonder what if anything they plan to do with the tremendous amount of waste heat?. Great presentation.
Thanks for sharing.

Comprehension is not understanding. Understanding is not wisdom. And it is wisdom that gives us the ability to apply what we know, to our real world situations

I too wondered about the waste heat. Probably not a reversible process.

The basic reactions are reversible, that's how you charge the battery.
Bragging that there's enough waste heat to keep it at temperature works for the ignorant.
I expect that the waste heat/losses are a function of a number of things - but batteries are never 100% efficient, and heat is where the lost energy appears.
I suppose in an industrial application - "grid level", you can use the waste heat to generate power...
Of course they always gloss over the fact that batteries are DC devices - and the grid is AC.
They will need some bloody huge AC/DC converters/inverters.
In the end, it may make 60-70% of that expensive power created by the wind turbines and solar cells become actually useful.

Cool. Waste heat will likely be horrible.

Also, I have seen the same design a while back using different materials. The way he talks about it is like it's 100% new, whereas only the materials he proposed are new.
Nevertheless, good talk and great idea.
