"You could design the beam to be so safe that you could take a nap in it with your child and not be affected," said Coste. "That would be at a power density level of about 10 watts per square meter. But that will require an extremely large area to collect [the energy], so we would want to have a narrower beam with higher density and some safety system around it." The company, he says, is looking into methods of "traffic management around the beam," using radars and lasers to look for objects in the beam's vicinity to stop the energy flow in case of a safety risk. "We can engineer a system that is designed to only be pointed at a receiver and would not ever work if it pointed anywhere else," said Coste. "We work on this concept with some big energy companies in Europe, and they don't see it as too much of an issue, as they are used to dealing with safety problems around high-voltage power lines or gas pipelines."
