With all the research I do on alternative energy technology I’m surprised I haven’t heard much about this form of power yet. Yes, it’s solar, but instead of converting light directly into electricity with photovoltaic cells — which is fairly expensive, intermittent, and without a viable energy storage solution — this age-old solution (in fact, thousands of years old) concentrates solar power into heat which can be used to run a turbine. Can’t wait to set one up at home!
