Hey guys just wondering if anyone has heard if the boys and girls at Red are working up some WiTricity intergeneration?

Seems damn handy.

What do you guys think, would you use it instead of batteries if you could???

Cheers

Lachlan

As great as this would be...and it'll eventually happen I seriously doubt this is fully ready for the real world...it would be very useful to have on set though, not just for the camera but can you imagine wireless lights?

You and the rest of the world, Rado.

I remember reading this like 2 years ago.

On the other hand I'm not very fond of waves flying around, imagine electricity.

Haven't we got enough cancer?

Yes he was.....on quite a few things...


WiTricity founder, prof. Marin Soljačić, MIT (link (http://en.wikipedia.org/wiki/Marin_Soljačić)) is very close to fulfilling one of Tesla's dreams...
He is concentrating on short distances transfer.

Do you own a mobile phone? Inverse power law says you've already got cancer ;)

Cell Phones use Radio Waves, WiTricity uses Induction and Microwaves. Radio waves are natural, so is induction to an extent with earth's magnetic field, but it's not a strong per given area as a wireless electricity system would be. Very close induction doesn't bother me as much, i.e.; electronic toothbrushes (but I still tend to stay away from them when they're charging) but being able to walk through an induction current is just disturbing to me.

I'm personally against any artifical use of Microwaves, other than microwave ovens or other devices in which the beam is encased.

The microwaves haven't been shown to do anything really but warm things.

The amount of warming you would experience is within normal bodily ranges. Being a bit warmer for a few seconds hasn't been shown to cause cancer.

From the FDA:

Much research is under way on microwaves and how they might affect the human body. It is known that microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. The lens of the eye is particularly sensitive to intense heat, and exposure to high levels of microwaves can cause cataracts. Likewise, the testes are very sensitive to changes in temperature. Accidental exposure to high levels of microwave energy can alter or kill sperm, producing temporary sterility. But these types of injuries - burns, cataracts, temporary sterility - can only be caused by exposure to large amounts of microwave radiation, much more than the 5mW limit for microwave oven leakage.

And any microwave carrying electricity would be way over this limit.

In order to have wide spread wireless electricity you would need microwave beams all over the place meaning

temporary sterility becomes permanent, because you're constantly exposed to that microwave beam.

Radio waves are anything but natural.

Some of the above is comic, however the graph is accurate. What we're talking about is EM radiation of differing frequencies and wavelengths. That's all.

Radio waves are produced naturally by stars.

Radio waves are produced naturally by stars.

So are gamma rays, X-rays, and UV radiation. Not all of them are good for us.

Very true... but radio waves, from what I know, are the least toxic of the bunch. We need some kind of wireless communication and to me the safest and easiest to work with are radio waves. What really needs to happen is to condense down the amount of radio waves we use, so we have more frequencies that are free for use.

how long do you guys think till we would probably see any of this tech in a regular house?

I love cables rather than live in strongly electromagneticaly polluted enviroment. I dont want to be grilled alive.:thumbdown:

Yeah... I use iDen, from what I know it works on a higher (or faster) frequency.

Maybe I'm getting more cancer than most.

If this becomes common I'll be one of those crazy grandpas scared of technological things.

I'm afraid of my microwave already, lol, imagine this.

Indeed.

We got rid of the microwave many years ago. Not sure how much safer we have been, as there's lots of other things in the environment that can harm you, but we decided to do it to also encourage us to cook real meals and in general eat healthier.

My thought, we don't need any more stuff hitting our bodies than we're already dealing with. Although wireless this and that is intriguing, ultimately what's the tradeoff for convenience?
