Gravity powered aircraft flies with no fuel
The concept of sustained flight without the use of fuel seems far reaching even by today’s advanced aviation standards. Even more so when you consider that aircrafts should ideally be able to carry heavy loads of passengers and cargo. However one innovator’s astounding new designs could transform the air transport industry of the 21st Century if they turn out to be valid.

I have read that there is also work being done on space travel by plasma fuel. Not that I know what that is or how it works. The gravity plane is cool, but did I hear “helium” mentioned? That is fairly explosive. Still, if this could be made to work so that it carried cargo and passengers on the scale today’s aircraft do, it could be a great savings to consumers, perhaps, and help reduce dependence on fossil fuels.

Well, how extremely cool if that all actually works. I suppose I would like to be a bit skeptical, in good form and all, but I’m sure if the Wright brothers would have showed me their plan, I’d be a little sketchy on that as well.
I love the future and this could be such a very cool future indeed. Imagine these things taking us to and fro – though they seem like they’d be alot slower than an airplane, so we probably wouldn’t eliminate airplanes…
I was also thinking how much more difficult it would be to spot one of these from the ground, without the noise or the smoke trail. Is that relevant?
