Btw, I've just been moved from 95% work at home to a mostly on site presence. Feugh.
Re: gravity and water as energy storage: Yes people do it, but I think it is necessarily a large project. Dinorwig power station's wikipedia entry is an interesting read. I'll look around for more examples. I remember a friend of mine telling me about this being done recently, but I don't remember the location.
