Cost is just the standard economies of scale. Going from MWh of battery storage to GWh of battery storage will produce those cost reductions. Li-Po batteries had had 20C discharge rates for many years. Nothing is really unexpected or breaking new ground. > Many technologies don't get adopted. I have not seen a falling cost curve anywhere in fuel cells. The fuel cell cars are still incredibly expensive, 100% not competitive and not getting rapidly cheaper. Fuel cells get pushed by China, Korea and Japan governments funds far, far more then any intrinsic cost curve that is happening in the market. Even after decades of constant investment by Japan, they have barley made a blip in the market and when they appear at all they are heavily subsidized all the way from research to the fuel stations. You suffer from the "not paying attention" disease. In the last few years, the biggest story in cleantech is the rapid reduction in fuel cell, hydrogen production, distribution and storage costs. Basically everything you said is obsolete already.
