The power would be converted to electricity on-board the spacecraft and sent to wherever it is needed on Earth by a large microwave-transmitting antenna or by lasers, then fed into a power grid.

All data collected by the spacecraft will get beamed back to Earth using a radio transmitter and an 83-inch diameter radio antenna.

Taken the Earth as material of antenna for receiving gravitational wave, the Earth behaves as a low-frequency gravitational detector.
