a electrically driven squirrel cage fan.

and a vacuum cleaner motor.

If they have fluid to push.
In a vacuum like space, nyet.

Depends on how many politicians you can force through a BIG version of those motors.

They will work, but they will not do work.

I wonder why the vacuum of space can't be "pushed"

the blades spin but they wont be creating ANY wind?

Industrial Cafe · « **Reply #5 on:** December 29, 2009, 04:32:47 PM »

is it because you can't compress the volume going into the intake?

no "air" in space(in concentrated enough volumes) to compress and propel you....

It might work if you added a Bussard Ram Jet Magnetic Field to the intake and add an igniter in the chamber.

so what if you put a whale in a space suit? could he swim in space?

I was thinking along the lines of a solar powered way to move you around in space. even if its slow.

Did someone say whales in space?

I like IC's question threads... but, I always wonder if it because he has a quest for knowledge or if he's just very clever.
Either way, all of these types of threads have been terribly entertaining.

Because space is not 100% empty they would produce an itsy bitsy teenie weenie amount of thrust.

I'm talking small, really small, smaller then could be effectively measured.

Here in the vicinity of the Earth the thrust from sunlight and the solar wind would be greater.

Unless you can get the Bussard collector running, but then warp drive is close so why not just use the blowers to cool your field generators.

Mark touched on this, but at least for now, using a solar sail is the only way to use sunlight to power a space vehicle, and last I heard it would take a sail about the size of Texas to propel a small capsule at a decent speed.

That would be pretty kick-ass though!

so if I mounted a small squirrel cage fan in a vacuum chamber with a feather in front of the outlet nothing would happen?

So we have found ways to produce and store sufficient amounts of anti-matter to make warp drive possible?

What if you were able to hang your butt out in space, would a fart propel you?......

if you farted in an empty bathtub would you still see bubbles?

If you were a fonzanoon you would.

If you fart in an empty elevator was it wasted?

seaweb11 · « **Reply #24 on:** December 30, 2009, 01:01:27 AM »

Wouldn't the motors rev up past their "purpose built" specs and burn out very quickly with no resistance on them?
