Yes, I did read those articles and it has me very interested. What I would be more interested in is some sort of applied DIY situation. Something I could cobble together myself and it would have the potential to get the efficiency that is discussed in lowtech mag. It seems to me that with the sorts of articles they write, I would be able to follow along on a small scale if I wanted. In particular, how do you make a compressor going one way and a generator going the other?
Please do this!! I want to see that article on CAES actually worked out in real life not just theory with no howto steps .
