I am so curious about this project and really hope for it's success. But heat pumps and PV curves have been studies for centuries. I'm super curious what Alphabet has to offer that is cutting edge. That being said, I really hope they are going to use a Stirling engine to convert the heat back into electricity rather than a turbine. A large scale maintenance free Stirling pump has always been my dream.
