I have, and I actually only just now figured out how to do it. Not easy information to find by any means... I still would like to hear what the people here have to say though. What I'm after is the ion wind. I wish to produce maximum thrust with minimum waste. I know fractals are useful for...

Howdy! How do I build a small low-voltage ion generator? The simplest possible design; we'er talking AA batteries here with step-by-step instructions... Any links or advice would be graciously accepted / appreciated. Here is a youtube video of the thing I want in case I'm not describing it...

I feel like my question has a been answered in a way that I can chew it : ) Thank you all for your contributions! I also want to add that I was not referring to a conventional combustion powered air-breathing jet. Rather a jet with an electrical engine, or mechanical one leaving combustion...

Aye. This is good. I understand that 1/100,000th of normal air pressure might not be enough to produce enough thrust to move an object.

A jet works by sucking in air & propelling it out the back. In low orbit, there is still *some* atmosphere present. My thoughts were that maybe a jet could still produce a useful amount of thrust even in such sparse atmosphere.

I don't think so. I know that one infinity can fit inside of another in math. The problem is that this also appears to be true in the physical world, not just in math... And I do not understand it. That is why I take it that this problem "Zenos Paradox" is beyond understanding. The concept of...

For the other levels of infinity, I was referring to the physical existence of objects that are infinitely larger or smaller than what we can see. The fourth dimension (time) may give objects a shape that we can't actually see... And there may be higher dimensions still. Some versions of string...

We're arguing over semantics here. I believe I answered the question just fine in an easy to understand way. Sure, you've probably read more math than I have, but that doesn't mean you can visualize 1 infinity baseballs. We're both right, share your cake with me.

I should've worded this a bit more carefully... When I said beyond human comprehension, I meant it in a more literal sense. We literally are unable to comprehend the size of an infinity, or one infinity fitting inside another. I understand that we can describe lines, planes, and infinities...

I apologize for the error I'm a bit fresh here : ) The engine doesn't need to be powered by combustion, so it could still work. An electrical (or mechanically powered) engine would serve our purposes here just fine.

Good ole' Zeno's paradox. It's fun to think about, but beyond human comprehension. Some infinities are just smaller than others. Points & lines are small infinities contained within planes, which are larger infinities. Planes compose three dimensional shapes which are the largest infinity that...

Here's a really complex & difficult question... Satellites orbit Earth in the upper thermosphere. Could a jet engine (not a rocket) produce enough thrust to move a small craft? The reason I'm asking is because it most certainly would produce "some" thrust in low orbit. The atmosphere extends...

Not sure if this is appropriate... but I tend to think of the future as a probability, with the current time simply being the one that had the highest probability of occurring. It is clear (to me) from the experiments that our actions do in-fact determine the future. The only question is... how...

I don't think it's iron & silicon we're after... Those are abundant "useless" minerals. What we want are the moon-sized diamonds floating around out there & the asteroids made of solid platinum... Well worth a trip to space & back and then some... just as long as it doesn't endanger the freaking...

"There is no limit." ... Well that was quick : ) Somebody delete this thread! lol. Thanks Drakkith for the shared knowledge.
