Is it possible to make electricity travel between 2 places with no wires?
It's called a TV.
If your definition is the movement of charge , then TV's fire electrons at the screen , high energy accellerators fire electrons and or protons around all the time. Electricity in fluids ( without literal wires) is carried by charged ions .
once you build up a great enough potential difference... most anything can conduct
can we send satellites to space that get electricity from sun and transmit it to earth?
A BOLT OF LIGHTENING...
Talking about lightning, is it possible for human to simulate lightining in order to generate electricity?
Wont this reduce pollution. We could send energy satellites to space send electricity to earth and use it. The pollution due to thremal power plants can be reduced.
One of the issues with transmitting a microwave beam back to earth from space is that the energy density of the beams would be quite large this would make it deadly to any bird or plane that passed through it. You would have to have some way of preventing such events.
I have ofter pondered the possibility of huge moon based photoelectic farms beaming energy back to earth.
Is it possible like for eg, that a country launches a satellite for electricity. Is it possible for the beam to accidentally unfortunately hit its neighbouring enemy country?
Ha ha, of course! But what would it do? Other than kill stuff? Knock out electricity too?
Spark gaps, jacob's ladders, toroids, and tesla coisl (or http://www.voltnet.com/tesla/index.shtmland ) use air as a conductor to work.
Also, there is something that may be relevent to this, it is called splitting an electron, you can spatially seperate an electron's charge and mass I believe.
Reminds me of SimCity, when the microwave beam misses its power station's receiver. Things go ka-boom. :)
Static electricity (lightning, cosmic particles, etc.) is not a good way of producing electrical current.
