THE US Navy has fired a pizza box sized satellite into orbit that generated enough electricity to power an iPad. It's designed as a prototype for a future system to send electricity from space back to any point on Earth. "Some visions have space solar matching or exceeding the largest power plants today - multiple gigawatts - so enough for a city," he told CNN. "The unique advantage the solar power satellites have over any other source of power is this global transmissibility," Jaffe said. "You can send power to Chicago and a fraction of a second later, if you needed, send it instead to London or Brasilia."
