Transfering Electricity w/o Medium? (Electron Beams?)

[SaudAlt]

Can electricity be transmitted using Concentrated beams without using wires with no energy lost in the process?

I would guess that if the electrons were completely free to move (i. e. not in a conductor), they would repel each other so it would not be a concentrated beam after a short amount of time.

But you could use some sort of electromagnetic radiation (microwaves maybe) to transfer the energy, and convert it back to electricity later.

Congratulations, you just invented the cathode ray tube

Here's a general article on wireless power transmission as I bet that's what you are really curious about
