Aquila is building wireless energy networks that use lasers to transmit power as infrared light. Its laser power-beaming system sends energy as infrared light from a ground-based transmitter to a specialised photovoltaic receiver, which captures the beam and converts it back into electricity. The broader goal is to create a wireless layer of energy infrastructure that can reach places traditional grids, cables and batteries struggle to serve, whether that is a drone in flight, a satellite in orbit or infrastructure in a remote location.
