St. James talks a great game. But FF is a combo structure, solar, and hydrogen production BIPV - and all are really in development. Nobody has gone commercial with QDSC, QD hydrogen production and BIPV at large scale. Its going to take more time than FF says, IMO, and there are other solar tech that will come to market before it, starting with stand alone QDSC products and the same with stand alone hydrogen production products, before an integrated product.
