How does an Ion generator work in space?

AI Thread Summary
Ion generators can function in space, specifically through ion thrusters, which require a supply of atoms to ionize. They operate by accelerating ions and ejecting both positive ions and electrons to maintain charge balance. Simply placing an ion generator in a vacuum and applying high voltage is ineffective, as un-ionized atoms would escape without acceleration. The process relies on the controlled ejection of ions and electrons to create thrust. Overall, ion thrusters are viable for space applications, but they require careful management of ionization and ejection processes.

Will an Ion generator work in space??

And how does it normalyl work? Does it push upon the ions in the air, or does it actually throw electrons, and this spins the rotor?

This is an Ion generator:

They very much work in space
Ion thrusters work, but you'll need a supply of atoms to be ionized.It's also reallly hard to ionize the atoms before they fly off un-ionized and unaccelerated and yet let the ions escape after they are accelerated. Sticking that mill in a vacuum and providing a high voltage won't do anything. Ejecting just electrons isn't possible, because the entire contraption would get a positive charge, and no more electrons could be ejected.
Ion thrusters need to eject electrons as well as positive ions.

 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
