This is corporate propaganda. Its expensive and won't be adopted. Expensive technology is stupid. People won't adopt it because no one has $100,000 to trench their yard - save a few tech workers in Atherton who wish to virtue signal.

We need abundant low cost energy. If it has to be carbon free - nuclear is the answer. I personally invest in Uranium because life is a struggle for energy and capital is really a form of stored energy. Nothing is more abundant in potential energy than splitting atoms. Its the answer we will reach.
California is experiencing huge annual increases in energy costs because of virtue signaling. This is more virtue signaling. Yes we can heat our homes with heat pumps. But it will cost 10 times as much money.
