    Invisible Wire
AI Thread Summary
The discussion explores the concept of creating an "invisible wire" using an electron gun to transmit voltage through a flow of electrons. It questions the feasibility of this idea in regular atmospheric conditions, as opposed to a vacuum, referencing historical innovations in wireless telegraphy. The mean free path of electrons in air is highlighted as a crucial factor that could impact the viability of this concept. Participants express skepticism about the practicality of transmitting electricity through air without a physical medium. Overall, the concept raises intriguing questions about electron behavior and electrical transmission in different environments.

Is it possible to make an invisible wire? Heres how It would work. You would have an electron gun shooting electrons and then you would have a wire carrying x amount of volts. Then you would put the wire into the electron flow. The electrons would then act as a wire and "transmit" the x amount of volts over a sertain distance. Would it work?

In a vacuum? Like a TV picture tube? If anyone remembers those...
 
no in air just regular atmosphere.
 
According to Lem many years ago there was a brilliant inventor who learned how to draw very thin wires. One day he draw wire so thin, that it didn't exist. That's how wireless telegraphy was invented.

When electrons fly through air, it's usually quite visible.

You might want to start with figuring out the mean free path of electrons in air. After you discover that, then you may want to rethink your original question again.

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
