But why not more microscale concentrated solar especially for DIY? For example parabolic mirror from a thin steel plate, or just a bended steel plate, (both in themselves >90% efficient?) -> liquid salt -> steam boiler system -> DC motor seems necessarily to me be a) more efficient b) cheaper to build than perovskite and also c) the skill - level required is very low tech (except the optional liquid salt phase). |
