Grid-based Energy Storage: Birth of a Giant

Greensmith is building systems for diurnal energy storage, peak shaving using energy stored during off peak periods to augment power during peak periods, which is a very cost sensitive market. It is also apparently trying to do so using an unspecified Li-ion technology. So it will find itself competing with systems from Axion and ZBB that can do the same thing but cost less.

Plug-In Natural Gas Hybrid Vehicles: A Game Changer

Way to go Fitzman! I spend all my time discussing the battery and storage sector because that's what I know best, but we have to stop assuming that what we currently know and already have is the best that will ever be. The times they are a changing and the rate of change will do nothing but accelerate. A good step in the right direction would be recognizing that none of the proposed solutions people are pounding the table over today are perfect and we need to welcome new ideas and test them thoroughly before accepting or condemning them.
