ABOUT
The Newton Gateway to Mathematics acts as a knowledge intermediary for the mathematical sciences. It is the impact initiative of the Isaac Newton Institute for Mathematical Sciences (INI). Supported by INI and the University of Cambridge, the Newton Gateway to Mathematics reaches out to and engages with the users of mathematics - in industry, business, public sector and other scientific disciplines. It helps to bridge the gap between those engaged in frontier mathematical research and those working in more applied areas, by stimulating the interchange of knowledge and ideas.

An excellent speaker who knows how to make a 700oC/0.5 V battery sound attractive :)
Great, been following that since the beginning... The only viable solution formulated till now, by far, where electricity is stored as electricity (instead of the dynamic potential of a mountainous lake/dam, or the kinetic potential of a gigantic flywheel, for example)... This is a humanity-dream come true, in a world so corrupt, where Lithium-batteries are still considered a suitable solution for mass-storage...
Of course, using a cheap battery means, that the profit-margins are smaller, so, except Sadoway, none follows that route, since the target is always profit-maximization, and not ecology, or future energy-safety. But there´s places outside of the US, where the people are neither blinded by profit-maximization, nor blind to the climate crisis...
Lithium can surely not be part of the solution, since the amount of Lithium that exists in the world, is maybe enough for a single medium-sized-country, but there´s hundreds of countries, and some of them are huge.
Bismut, as mentioned, would be an even tiny-bit-better substance, but, of course, it´d be irresponsible to take Vietnam´s Bismut for that, cause that´s what Vietman has to use fot its own locally built Ambri-batteries... Aside to that, it´s too expensive for everyone else, but the Vietnamese...
The cycle-efficiency can of course rise, by building well-isolated walls around the sum of all those ship-container-sized-batteries, that make up a single power-plant... There´s nowadays no reason that heat escapes, surely not with the help of some german expertise (here, there´s passive houses, that need just 30 gallons of oil for their entire annual heating-needs, and cost just 8% more than normal houses, 2010 figures)... But the cycle-efficiency is fairly high anyway, maybe falling 10% short of the best batteries out there, that are completely unsuitable for mass-electricity-storage...
I can´t see what is he pointing at.
