The transmitters are currently the primary way to transfer energy across any sort of usable distance. They take in energy into their internal buffer before transmitting the power. The power is transmitted in a packet of a certain size. The transmitter waits until it has enough energy in the buffer to send the packet. There does not seem to be any energy loss with distance, so long chains of laser transmitters have no power downsides. For other ways of transporting power, see Power transfer.
