actually, any environmentally derived power has this problem, potentially. specifically, the amount of power cannot be shifted to meet demand arbitrarily. so, we can either store the power, over provision, or change our lifestyles to match the available power.... not mutually exclusive ofcourse. personally I think we need to do all three. :-) storing power is actually relatively easy. batteries are fine but lossy and environmentally troublesome, but they work. energy density is a serious problem here... I beileve (from memory) that zinc is a reasonable material for storage of electrical power. better from my pov is PV decomp of water then use the Sabtier Reaction (reverse water gas) to make methane from H2 + CO2 over Pt hotwire or Alumina supported catalyst. - or just store the H2 - though this has other problems. when you want to use the power pass the methane or H2 through a fuel cell, keeping the reaction products for the charging cycle... :-) liquid fuel self presurising battery! -- Dr Paul van den Bergen Centre for Advanced Internet Architectures caia.swin.edu.au [EMAIL PROTECTED] IM:bulwynkl2002 "And some run up hill and down dale, knapping the chucky stones to pieces wi' hammers, like so many road makers run daft.
