A bunch of my non-techie friends have posted this link on Facebook yesterday ... my response has been, "oh, my, more surface area of course means more generation in that footprint." NB it's one of those idiot "futurist design" websites, with zero technical competency. |

This idea is not as crazy as it looks. They are using an array of solar cells with lenses in front of each device, then rotating them so that the sun does not stay on one cell too long. Think of it as solar multiplexing. Does anybody have figures concerning the lifetime of solar panels when they overheat? |

Reminds me of the TV show "Earth 2" they had spinning solar cells powering vehicles |

How do they intend to transfer the power from this thing - rotary transformer? Also something tells me that solar cells will act like LEDs with such PWMed power (drop efficiency). If you put 10x power with 1/10 duty cycle, it won't be nearly as effective as with much lower but constant power. |
