Would Tesla, SolarCity or SpaceX exist without $4.9 billion in government subsidies?

[ Tesla has made no new battery breakthroughs. Batteries aren’t much better today than they were 200 years ago.  All Tesla did was build a better battery management system (BMS) by stringing tiny batteries together — thousands of them.  But … Continue reading

The potential role of concentrating solar power

Preface. The word “water” appears nowhere in this document, even though that’s a major limiting factor for CSP with thermal storage. Dry cooling is possible, but it lowers the EROI and raises the already way-too-high capital cost. An electric grid … Continue reading
