Sorry I am a bit late on this discussion but would like to add my two bobs worth.
A system I am interested in is a solar/wind one where it converts excess power into compressed air for later use. I live on a farm in Australia so at some times I have an abundance of power and other times ie at night, do not. Hence I need something that will store excess so I can use it later on. Efficiency is not a concern as the potential is there to collect far more than I need. Energy could be used to power anything, house car.
Any ideas?
