Cool. I've always wondered about this sort of thing, like if it was even possible. Nice post, I'd like to see how quickly this is advanced.

Could we put solar panels in space, to capture literally direct sunlight, and transmit the power to earth through this technology?

[which doctor]

When I was young I used to think that if I invented some way to transmit power wirelessly, I could make a lot of money. It's cool to see that it's actually going to happen.

[Political_Chucky]

yea thats pretty bad ass. No more searching for those damn batteries! The product that has this is gonna be expensive as fuck though I can tell you that.

There would be a distance problem and of course a maintenance problem as well.

...and the fact that if you had them connected together so it looked like one giant panel, it would block the light from the sun and kill whatever plants are under it.

Do it too much and you'd be in trouble ;)

if you had wireless energy flying around in the air to different devices, couldnt you get electrocuted? i always wondered about that.

Well, yes if the energy were in the form of electrical energy! It could not be in that form, it could be in the form of (say) mechanical energy, or chemical energy, or something else.

Just because it's energy doesn't mean it is energy in the popular sense of the word (electrical energy). So you wouldn't necessarily get electricuted!

Plus you only get electricuted when the amps are low and the volts are high (or vice versa, I have forgotten being the old fuddy-duddy that I am).

Why would we have to place it such? It could orbit the moon or something.

but how could you transfer chemical or mechanical energy from one device to another without some sort of connection? i know i sound like a tard, but i have very little knowledge of physics.

How to transform chemical energy into mechanical energy? Well, that's how a gasoline engine works. There is no electrical energy there, just a combustion process (chemical energy) which is used to move pistons (mechanical energy).

"And because we're physicists we asked, 'what kind of physical phenomenon can we use to do this wireless energy transfer?'."

Crazy physicists.

I guess it could be dangerous if there is something else in the vicinity that resonates at the same frequency.

I don't know how efficient it would be though, that is how much enegry you would be able to pick up from how much would be put out. Not that the energy would get "lost" but some of the energy would change andI dont think efficiency rate could be extremly high.

The basic concept though is rather primitive. However it gets more complicated when you must efficiently change the energy from the resonating antenna into usuable electricity.

It looks like Telsa was right all along <_<

yeah but he faced the traditional enemy a lack of money.

tesla was a genius i wonder if his more "fantastic" ideas would have worked like his anti gravity device.

I think that the idea of generating electricity in space and sending it to earth via waves could easily solve all energy problems The sun is really fucking big and solar panels are not gonna block it. I mean, there are two whole planets orbiting between the earth and the sun, and they don&#39;t seem to be blocking any light.

We could use microwaves

It depends on the distance to the sun and the earth; if we create "artificial solar cell planets", then it could conceivably work, albeit so ineffeciently it would be comical.

Using current solar cell technology (the cells which are 30% effecient), supposing that the energy method&#39;s effeciency is 15% (which would be remarkable), and there is a distance r between the Earth and the artificial body, then the effeciency would be nearly negligible (.15*.30*(E-.5*f&reg;) &#092;approx 0) which means that it&#39;d be not that effecient (the effeciency approaches zero as r approaches infinity).

And microwave radiation? What about that effect on humans? :huh:
