A drone with wireless charging can hang in the air forever
The prototype of a quadrocopter from the laboratory of the London Imperial College is devoid of the Achilles’ heel of modern autonomous machines – all of them are extremely limited in energy reserves that they can take with them on a flight. Therefore, some inventors are on the way to developing innovative fuel cells, while others are experimenting with charging jacks on house spiers and lampposts.
Dr. Sam Aldhea offered to give up batteries altogether – instead of them his apparatus is equipped with a frame made of copper foil. It serves as a receiver of electromagnetic waves, when the drone is above the emitting conductive plate. The system is identical to wireless chargers for Qi smartphones and allows the micro-robot to transmit energy without direct contact with it.
The prototype is a prototype – even though the drone is kept in the air, but only at an extremely small distance from the charger. If you build a highway along which the Copter will travel at a height of a couple of centimeters from point A to point B, this negates all the advantages of aircraft. Therefore, for the time being, the most intelligent application of the development is the decoration of the scientist’s desk.
