Re: > blasting microwave radiation at a watery chemical soup
Two separate things: power and storage. Spain could probably already meet most of its power demands using solar power during the day, but not at night and also it also requires a lot of land, because yields are relatively low. So chemical storage, which can be produced when there is excess capacity, and then used when their is excess demand is required; build it up on windy nights and warm sunny days, use it up when it's cold and dark. You want something with high energy density that is easily transportable.
