Why not? There could soon be some type of a hybrid system design to boost the fuel economy of commercial jetliners.

Amazing!

I'm one of a bunch of electic-launched radio control sailplane pilots who will be watching this technology.

I think this would work more efficiently if the plus electrodes are situated in a cylinder in the front portion with a narrowed center portion like a sand clock and slits behind the narrowed portion with the minus electrodes lined on the edge of the slits to maximize fluid dynamics.

It listed possible military applications including the development of silent drones and aircraft, and engines with no infrared signal and thus impossible to detect.

Maybe with this part we will see faster development of the technology.

It is awesome stuff though.

Sadly enough, if there is a possible military application the money to develop it will magically appear.

The pussygrabber clown in chief of the WH, the republican happytriggers and the carbon-gas pirate industries hate this kind of great News !!..

Something tells me plane tickets will not get any cheaper once this is implemented. The airlines will pocket the savings for the shareholders and customers will still pay an arm and a leg to get packed like sardines.

The two things - a technology barely off the drawing board, and the price of commercial airline tickets - are so unrelated and so far apart that the question isn't even worth considering.

This technology may never even be implemented in commercial airliners, and in a much shorter timespan, say 50 or 60 years, the airline market itself may well have evolved into something quite different from what you're familiar with today.

About six years ago around 7 am in the south of France three completely silent aircraft flew at about 60mph over my head. They were about 300 metres above ground and appeared to be each the size of a car. They also seemed to have no discernible wings. I didn't think they were alien. Now I know it was probably this technology. But it just shows the military are probably already using this or similar inventions.

It clearly wasn't, as this technology has only achieved a low-speed flight at less than head height for a few dozen metres. And it has a discernible wing.

"Completely silent aircraft" have been around for a long time, in various forms, as have aircraft that produce sound but that in certain conditions are inaudible from the ground. No one would doubt that you saw an aircraft you didn't hear - but the propulsion system wouldn't have been this.

A silent drone for big-brother or stalker.
