   Wow. Did you know this? There exist *power over fiber* components that can provide 3v 180mA from 1.5W of 800nm infrared light coming through a standard multimode optical fiber.

   These are very expensive, but also very cool!

     in reply to
     @f4grx at first I was like blah blah blah this is just thingy.
     
     Then I read the document. Did you catch this? That it is a power converter from light to energy at 50% 25c reference? 45% at 85c?
     
     Lets take your standard home roof? thats 139 kilowatts per hour. 695 kilowatts for the standard 2000sqft house. per day, the average house uses? 936 per month. thats a surplus of 20203kWh per home per month.
     
     This will change everything when its scaled up.
     
     Standard Constants used.
     
     2000sqft house = 3000sqft roof = 278 m2
     1000w/m2 = .500w/m2 at 50%
     Average consumption = 936kWh for residential home in usa.
     standard day solar insolation = 5hr
     
     the rest is easy math.
