Wireless Power

**ElectroPhysics** · Nov2-05, 01:02 AM

My question is how to generate wireless power i.e. cordless power to power up electronic/electrical equipments. Any link to research that has done on it & other startup links. How can you help me learn about it as early as possible.

I will be back on next monday to see the thread.

Best Regards

Batteries.

Or do you mean transmitted wireless power?

There are a number of ways to do it, but there isn't anything that is really feasible. What exactly is the purpose of this?

I mean, as an example to power up the television set without using power cord connected to 220V/110V ac wall socket.

It is a research oriented project and we will hopefully get funding for that.

All that I can think of that would be applicable on that scale would be the aforementioned batteries, built-in generators, or inductive pickups. The SPS beamed-power proposals use microwaves, but you don't want to be messing about with that stuff in your living room.

Well, there are radio sets which don't have any batteries. The strength of the radio wave is sufficient for (faint) music/whatever.

Other than this, why don't we use about 100 million volts.... that should be able to travel about ten meters....... heh

As I mentioned before my research will be wireless based i.e. on electromagnetic waves.

ElectroPhysics - what type of power level and distance between transmitter/receiver are you talking about?

**russ_watters** · Nov8-05, 10:09 AM

Well, it looks like about 200w and about 5m...

Have a look at this: http://en.wikipedia.org/wiki/Rectenna

You could also just point a laser at a solar cell.

The transmitter should able to provide sufficient energy to power up all the equipments e.g. present in a house and should cover the range of this house.

The equipments are not fixed in a place and as stated earlier we have to find its electromagnetism based solution.

Omnidirectional power transmittance requires an enormous amount of power, since the vast majority doesn't go to what you are powering, but, rather, is absorbed by other objects, the air, etc.

You could simply turn the entire house into a walk-in microwave oven. That would work. Any person trying to watch TV in that house would cook and smolder, though.
