I know of an submarine ROV for hydrographic work that uses a similar principle to cross oceans on a very small battery.

For an airliner though I shouldn't think so.

It runs on gravity? Isn't that a glider? Tongue

I love the way they say completely free of fossil fuels ....... So manufacturing the Helium and compressing both that and the air for ballast don't require anything apart from a man blowing into a bag. ??? ???

I'm with Doug on this one ...... and await the time when we're proved wrong.

If you are willing to wait long enough solar/wind power could provide all the energy for the needed materials and manufacturing.

Of course, this isn't really a plane...it's a gravity propelled airship. There's no reason that the concept can't work in theory...it's just finding a use for something with this weird set of limitations. Perhaps long range cargo?

There is no such thing as an equal exchange of energy. If it refills its compressed air using ram air turbines while gliding, that would create drag. The craft would lose more energy to the drag than it could ever generate with comprssed air. Am I making sense? I don't feel like I explained that very well...

Personally, I assumed that they were only describing the primary method of compressing the gasses...energy exchange limitations would affect things just as you say.

Some form of solar energy would also be required to my mind...either solar heating of the gasses to aid expansion and create additional lift or active solar panels to create electricity to augment the various processes.

C'mon, those guys in Nevada have been supposedly back engineering alien space ships! I think they must have some much more interesting propulsion and gravity defeating systems than helium and compressed air! Ever heard of 'element 115', 100% mass to energy reactors and 'gravity generators'?

Craft, which generate their own gravity to counteract the effect of Earths. Then using directional gravity generators so powerful they literally distort time and space in split second intervals in order to move around great distances in space otherwise inaccessible through conventional propulsion systems.

It's all word from suspect sources of course, but so is your 'perpetual motion plane' and to be honest I’d sooner believe the spaceship story! Grin

Hear, hear... Grin

I've heard that story; supposedly all that's needed to get it running is that super-heavy element for the critical mass. Maybe they got one flying but it winked out of existence only to wind up on the other side of the galaxy because somebody pushed the wrong button... whoops. Lips Sealed

this sounds possible tho

i wouldent like it even though its over a long distance the up and down would annoy me Grin

Theoretically it is possible, assuming you have enough battery power to run the pumps. But then again, all to often theoretical ideas turn out to be impractical objects.

And what about winds aloft? How is such a delicate propulsion system gonna cope with 100kts trade winds?
