I have a problem that can't be solved. So then, I put it to this Physics Forum to see if anyone comes up with a brain storm ( or directs me to a solution which my expert may have been unaware of ). Doing Power over Fiber is "impossible" today for a broad-based residential application because the conversion is so poor ... once you get up to 20 watts you only get 15-20 % maximum. As such, it has very limited application in small electronics. The cost also is prohibitive. My objective is fiber optically wired homes doing not just data but power as well. Evidently, the power part is not possible. Does that apply as well if the power is DC? Any ideas? Thanks ( and pardon me if my questions and statements lack clarity or rigor ).
