that is to transmit without using Wires

you can make electricty wireless. Put a metal wire near an exposed electrical wire and the electricity will jump from one wire to the other. Actually, dont do that, you will electrocute your self. The same thing happens when you get shocked from a door knob. The electricity will travel before you touch the door knob. There are some problems with making electricity wireless though.
1. Its hard to make electricity travel a far distance unless it is very VERY high voltage (look at lightning).
2. Too dangerous. Someone could get badly hurt by it. And electricity is always looking to get to the ground. If electricity is being sent through the air above a road, and a large truck passes underneath, the electrical current might go to the truck instead since it is grounded.
3. It would probably be expensive.

Yes and No. We do this already. Electricity is just energy no different from the wireless energy of your cell phone or wi-fi network. We use wires to transmit electricity, antennas to transmit wireless signals.
The problem is one of scale. Your cell phone receives and transmits a tiny amount of energy through it's antenna. This tiny amount of energy (electricity or electromagneitc field) is enough to transmit information.
The electricity (or energy) required to power your television or stereo is many, many times the power needed by your cell phone. Scientists have built "machines" to transmit energy at this level for various experiments. The problem is that our world is full of electrical conductors or "antennas"
Imagine if we were to transmit enough energy to power your stereo, but, the signal were instead picked up by your iPod. The electricity would travel down the iPod,up the headphones and right through your head! Ouch! I wanted to hear Bono, not Ben Franklin!

It's already been done! If you live under or near a high tension power lines take a florescent bulb and stand under the lines and watch it light up without any wires to the ends! They lose up to 10% of the power they are sending! If you can find a way to prevent this loss they will print you a blank check and you can fill in the amount!

Look up Nicola Tesla. He acheived this but power companies destroyed the technology because you could get free energy from it by sticking an antenna into the atmosphere, thus not having to pay for it.

Electricity is wireless (see induction topic) but only ac perhaps.

We are working on it, but so far 3 researchers have been burnt ot a crisp

I hope they could do that someday soon, I hate when my T.V cords gets tangled with my Video game cords.
