Is wireless power possible?

Yes wireless power is possible, and is already in use.

Lookup "Passive RFID Tags" as opposed to "active". Active tags have batteries, passive work off a magnetive field that the reader produces. And since passive tags are used as animal implants, no connection can be made - they're under the skin.

its like those light sticker thingies for the cell phone..when the cell phone rings, the sticker lights up...

I highly doubt something like that would be healthy for us humans, standard electricity send through the air might be dangerous.

what would the difference be between wireless power and a wireless signal such coming from hugh cell phone towers all over the place?

Consider the example of the lightbulb in the microwave.

What happens to water based items that get put in the microwave?

Yup. That's how some security badges work. I used to use one for years back at an old job. 🙂

Yep. Read on... courtesy of Wikipedia

It's possible to produce a stimulated muwave emission with coherence that could transmit power great distances to a receiving station. Such an idea was devised to send power wirelessly from orbiting photovoltaic power plants capturing energy from the sun.

It would also make a fierce weapon that could take out delicate networking infrastructures with surgical precision and thus is not discussed often for obvious reasons!

my electric toothbrush would charge wirelessly.

I've seen a wireless charger at a Science Museum while in Hong Kong.

 

[statik213]

this was hyped abt a few years ago... looks like itnever took off. probably one of the neatest ideas in a long time.

It would have to be pretty dang powerful.

Network infrastructures - delicate wouldn't be the word I use for them. More like bullet proof.

Quick patent security for wireless electricity.

microwaves or induction

 

[The Woot]

You may not be able to transfer electricity directly (or you may, see prior posts), but you can convert it to something else and convert it back to electricity... for example, flashlight converts energy to light, solar panels convert light to energy... light moves without wires, thus, wireless electricity.

air is a very poor conductor of current.

a light bulb creates light by heating up something (usually tungsten). The only reason the light bulb comes on in the microwave is because that is heated up.

It's cool, but I've got no idea if there is technology advanced enough to send power wirelessly over the airwaves in a safe fashion.

You major in business right??? Well I hope so because you're definitely no science major.

Incandescent, generate light from heating the coils in the bulb. By placing the bulb in the microwave and turning it on, the coil is heated up and generates light. No electricity is produced in the microwave.

Never heard of it honestly other than a way to smooth out the jaggies.

I remember those microwave power stations from simcity 2000... those things always blew up:Q

Kinetic batteries are probably what you're looking for. They have them for watches, and they're working on them for cell phones right now. These batteries recharge from movement. Just walk around and the bouncing recharges the phone.

Well there is one product I can think of right off the bat that would benefit from that. 😉

There are all types of ways to transmit power wirelessly. The problem is using power wirelessly. The more power you need in a tighter specification the harder it is to do it safely. I am assuming that you are speaking of powering something like a MP3 player. Well batteries are wireless power, and are pretty much what we are stuck with for a long time yet. Battery power density is going to continue to increase in the foreseeable future, and electronics power consumption is going to continue to decrease. I think soon we will be at the point where batteries are not such a pain.

You and I think alike...we must be right on the same page with the same ideas 😉

Unfortunately, a refrigerator is WAY to heavy to carry around. That would be cool though.

I think so Brain, but where would we find rubber pants at this time of night?
