Laser-powered, ground-charged UAV stays aloft for hours – Homeland Security Newswire

A UAV is only as good as its power source: if the drone cannot stay over target for long periods of time and must return to base to refuel, this not only adds to the costs of operating the drone but it also degrade its intelligence gathering capabilities; Seattle-based company demonstrates that it can use a laser beam to charge the UAV’s photovoltaic cells, generating enough power to keep the drone in the air for hours; the company has bigger plans for extending flight duration of military craft — and much more: in the longer term, it envisions lasers powering remote ground-based sensors, delivering power to forward military bases, or supplying emergency power during disasters
