Ah, but the problem that you foresee — solar takes up too much space — doesn’t exist yet. Hard to drive investment for a problem that is years away. I wish Thorcon luck, but the big money is out to answer the question: How low can solar prices really go? Is $0.01 per kWh achievable a decade out? What price point would Thorcon have to hit to be viable?
In a rapidly moving market like this, the first to scale wins. Even a better underlying technology can’t enter the market if the price floor keeps dropping out below it. That’s the struggle of any new power generation technology — we are unlikely to see much new until solar and wind run out of steam. (Bad metaphor intentional.)
