DailyDirt: Impractically-Powered Planes
from the urls-we-dig-up dept
Some methods of flying are better than others. Passenger comfort isn't always the top priority for some aircraft, and that's especially true when engineers are trying out really novel designs and propulsion ideas. Here are just a few examples of some new planes that aren't quite ready for commercial flight, but that look really cool on the drawing board.- A solar-powered plane prototype was demonstrated at the Paris Airshow. Unfortunately, the plane requires almost windless conditions to fly, and it's not too fast. But it *can* stay aloft almost indefinitely (greater than 24 hours so far). [url]
- The VoltAir is an all-electric plane concept with superconducting (!) electric motors... "VoltAir is an upstream research concept, not a near-term commercial approach." Duh. [url]
- If superconducting electric motors seem plausible, then using a low-energy nuclear reactor (LENR) to power a plane is just around the corner. I'd like a Mr. Fusion generator for my DeLorean, too. [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

It was a time when people were scared, both Americans and Russians were trying to outdo each other and the Russians had no value for life.

Re:
To explain a bit further, even if the reactor can not sustain the maximum instantaneous power required during a typical flight (take-off being the big power hog), there are plenty of means to store excess energy during periods of low power consumption (taxiing, cruising, initial landing approach) as electrical/chemical/mechanical energy. In fact, operating the reactor with less variance in power demand by using such an external energy capacitor is often desirable as it introduces fewer overall deviations from nominal design conditions to the system.

Re: Re:
Did they managed to make a truly closed system, last I heard it was not that simple, doable but not practical not even today.

Re: Re:
But maybe it's possible for military planes since there are plenty of nuclear-powered submarines.

A sub nuclear reactor is 2 to 4 stories high.

Also the military have nightmares on the liability of those things in case of accidents.

I imagine sooner or later, the FAA would have required at least a small backup battery to allow the plane to safely land if the broadcast power tower failed, but it wouldn't take much of a battery to power a plane for 5 minutes or so.
