Our company GET (Global Energy Transmission) has built and successfully tested the world’s first prototype hardware that can wirelessly power heavy drones over long distances. The prototype shows, that we can build a cell-tower like power network for drones, so that drones can safely grab enough energy in seconds to fly payloads across the charging network to stay aloft indefinitely or reach delivery destinations.
The key feature of the technology is a long length flexible transmission cord, which forms area of energy reception with a distance of up to 20 meters from the cord. Separately, each drone should be supplied with special receiving hardware.
The transmission cord concept allows us to offer unique solution for industrial applications since such cord can be placed around the building, construction, or any other object, providing wireless power for drones, which can operate in a 24x7 mode in the dedicated area without recharging. This can be used for monitoring, security and other applications.
Additionally, using such transmission cord, we aim to deploy charging spots for drones, making wireless power network for them. How it works:
• Charging spots can be located on the top of the roofs/in dedicated areas
• Drones can be charged on the fly (over the charging spot and in 10-20 meters from it)
• During several seconds, drone can grab amount of energy which is enough to jump to another spot in a several miles distance
Key competitive advantages compare with other solutions:
• Waterproof, works at any weather
• No necessary of precious positioning
• Charging multiple drones simultaneously without limitation (up to maximum output power of the transmitter)
• Preliminary research shows lower costs for manufacturing, installation and usage
We are sure this solution will fully disrupt commercial drone-enabled services, especially for commercial delivery and monitoring.

Hi Dmitry,
Thanks for your questions.
1) Not really. Of course you will have decrease of efficiency as you are moving away. However in general you have low losses as long as you are at a distance comparable with loop diameter - no matter whether you are moving in horizontal or vertical direction. Regarding this concern - we've made both calculations and practical tests which are in excellent agreement. Flying inside the loop is just for safety reasons.
2) We've fully tested FMC compass and magnetometers and they are not affected by the field, totally.
3) a) all those possible metal object are not resonant circuits, therefore you will not have any noticeable losses. b) in fact mounting transmission cord at a height of 1 meter or so from the ground/big metal objects is enough to make those losses very low.
I think the big word I 'd have liked to see is efficiency. Are you spending a Megawatt to supply a Watt?
One more question..
3) What are you going to do with power transmission loss due to accidental conductors that may happen to be located inside of huge powering loops? What about eddy currents in a wet ground, metal roofs and other constructions?
Hi Dmitry,
1) To fly copter inside of the powering cord loop is definitely not the same as to fly it at 10-20 meters over or aside of. You will have a huge power transmission loss. Do you have the same demo with a copter that hovering at 10 meters aside out of loop?
2) How are you going to prevent FMC compass/magnetometer from bias induced by your powering system?
