- if only people can solve the storage problem How cheap store a lot of power on a large scale, renewable energy may be the world's major source of energy? The battery is too expensive, can't last long enough. Pumping station is cheap but not feasible for most places. Heat storage is very promising, but it is still too expensive or difficult to expand. Compressed air is cheap and can be extended, but efficiency is not high, Despite the LightSail is a by Peter Thiel, Vinold Khosla is Bill Gates, and support of the new company, hope to change this situation) 。 The flywheel? The biggest players Beacon Power went bankrupt in 2011.
