The Hyperflux Transmitters, created by [Redacted] tech company based in the Andromeda galaxy, work in tandem with the Hyperflux Stellar Batteries to transmit free energy to the civilians of the Sonwil Empire and beyond.
The batteries plug into these transmitters that are located on planets, moons, space stations, etc. and transfer electricity wirelessly. While one battery contains enough charge to power an entire planet the size of Earth, multiple are kept on each planet or structure for redundancy and stability.
