Nice article. Especially in the way it emphasizes energy efficiency over just trying to continue to power the things we already use. One thing I would have like to have seen discussed, in the section on non-battery storage, is pumped liquid storage. This is a great technology for grid scale storage, but I wonder how well it could be applied to small scale instalations. I would think something on the scale of the Living Energy Farm would be able to make good use of this, and maybe even smaller scale, like with a 50gal tank on his balcony?
