A new heat engine with no moving parts is as efficient as a steam turbine
This is great, but all of this feels like it&#x27;s coming 15 to 20 years too late. I worked with a guy in Berlin who had previously worked in PV energy. He predicted that unless the costs were reduced by a factor of half the price point of fossil fuels that it would go nowhere. We&#x27;re addicted to cheap, no hassle sources of energy right now, and it&#x27;s depressing.
