Alternative grid batteries: iron-air and sand

Happy New Year - let's talk Energy! Richard chats with Carl about the state of energy generation in the world today - and things are progressing! Almost every kind of power generation is expanding at the moment, whether you look at solar, wind, hydroelectric, natural gas, coal, oil, or even nuclear! The cost of batteries hits a new low, and new technologies being demonstrated today show that storage is only going to get bigger. And what about the impact of AI on power generation? There's a huge change coming to electricity, an AI may have accelerated that change - but that's only part of the equation!
