Does anyone here feel qualified to discuss electricity in space. We know that it exists but we do not know very much about it. I find the subject very intriguing but I know very little about it. Thanks for comments. Joe L. Ogan
What is its' relation to astronomy? Thank for comments. Joe L. Ogan
I'm not sure one would say that everything is known about anything.
They are quite different things.
a : a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons b : electric current or power 2: a science that deals with the phenomena and laws of electricity 3: keen contagious excitement <could feel the electricity in the room>
In electricity, we generally either push electrons along a wire by forcing them to go from high energy to low energy (DC current) or we cause electrons to oscillate in a wire and extract energy from this oscillation (AC current). We can't easily get DC current to flow in outer space because objects in space are generally electrically neutral overall, so getting electrons to flow from one to another isn't going to work.
AC current won't really work because you'd have to connect a conductor between the earth and a distant object so that oscillations in that object could cause oscillations in electrons here on earth.
Is electricity in space the same as radiant energy?
If it is we already use radiant energy in certain things such as heating water, heating the house etc.
But we have no direct connection to use it as an electrical source.
Is this possible?
Just because it has not been done as yet doesn't mean that it is impossible. It just means that we have not discovered a way to use it as yet
This means that generally you don't see them firing beams into space.
Similarly, you'd have trouble finding a naturally occurring AC current that propagates through space, and certainly this type of thing doesn't commonly reach the earth.
I'd have to check the numbers, but I suspect the flux is too small to be very useful to us.
Of course currents induced by the Earth's ... magnetic field would be small for a small coil, but it should be detectable enough to aid with orienting the spacecraft, or for research.
