The Defense Research Intelligence Agency , the gonzo R&D sleeve of the Pentagon , has had a hand ininventingeverything from GPS and speech translation to the other precursors of the internet . ( The agency also tried to develop amechanical elephantto traverse South Vietnam , but who ’s keeping count ) . Now the way is working with a inauguration to explore way to wirelessly charge drones mid - flying .
The society , Seattle - based Electric Sky , was awarded $ 225,000 as part of DARPA ’s Small Business Innovation Research Program to create what they ’re calling the world ’s first “ Whisper Beam ” transmitter agree to apress release . While former wireless charging for drones has rely on microwaves and lasers that get weaker as they locomote over a length , the Whisper Beam aim to do the opposite and would get stronger as it approaches a receiver , the companionship ’s chief operating officer Robert Millman said . Electric Sky reportedly use a transmitter that sends out radio wave that then center on the receiver , in this case , the drone .
“ Whisper Beam engineering is the electromagnetic equivalent of a whispering gallery , ” Millman said . “ In a whisper gallery a single listener across the room can get wind the verbalizer but no one else can , not even mass standing forthwith between the speaker and listener . The sound is too weak for them to hear . ”

DARPA has a prospicient history of interest in drone projects . For age , the representation has visualize a course of study calledOFFensive Swarm - enable Tactics(OFFSET ) that would see drone horde of up to 250 remote-controlled aircraft introduce battle alongside small teams of soldier . The federal agency believes these modest drone armies could soon help soldiers in clear buildings in urban areas and conduct reconnaissance mission .
Earlier this year , DARPA successfullydemonstratedits ability to catch a X-61 Gremlin drone and safely turn back it to a nearby C-130 planer mid - escape , an accomplishment look as a pregnant milepost towards hold drone drove a reality . Meanwhile , the agency is also working on a counter - drone operation that would employ drones attach with detector to detect and class other drones in urban environments , notesC4ISRNET . So many drones !
DARPA and its partners will have to solve the wireless charge trouble ( not to cite bring down trailer costs ) if these Call of Duty - esque swarms are ever die to get hold their way bombinate through field of battle . That ’s where Electric Sky add up in . As part of the first phase of its work with DARPA , Electric Sky will build and trial run demonstrations that can potentially work at short distance . Data from those experimentation will be used to upgrade the systems for long distances . In theory , Electric Sky co - founder Jeff Greason told GeekWire Whisper Beam could work out with any type of electrical aircraft .
“ It ’s a myth that foresighted - distance index transmittal is impossible , ” Electric Sky carbon monoxide - founder Jeff Greason said . “ It ’s just never been stinting . This new method acting reduce the price of the land transmitter and the size of the vehicle ’s onboard receiver . ”
DARPA investments are worth keeping an heart on even if you ’re not particularly interested in the prospect of room swarming imperialist death bot because many of the agency ’s programs finally trickle their way down to daily consumer . Though DARPA probably did n’t put in GPS research think the technology would one day empower a college student to incessantly track their pizza delivery at 4:00 a.m. , well , here we are . It ’s possible something similar could fall out with wireless charging somewhere down the route , though it ’s still far too other to tell .
