A Look at Claymore's Solar Energy ETF

I hear a lot of hype on Solar wind and Geothermal and Wave power. It is like going to fetch water at the river or well with a bucket full of holes. Who is making a good bucket to hold the energy for when it is needed? Certainly Hydrogen is interesting but is it efficient? What about Thermal salt storage? If they are that good why no one gives us the real lowdown as to loss, efficiency, cost and real estate footprint required for deployment, not to mention red tape by government? Any suggestions anyone?
