but spend $billions on coal infrastructure - that seems crazy given the inefficiencies and c02

With mass production maybe we can get these bluegens can get below $10K

My thinking is before billions is spent on coal let's take a deep breath (not near a coal power station of course) and think maybe this is a good opportunity to trial or push some technologies that may be better suited to meet the needs of the world of 2020

Anyways thats my rant ;)
