when will wireless electricity be available to the public?

Answer 1

Long distance wireless electricity is not practical, for the same reason that long distance lighting is not practical.
(What I mean is, you need a street light at least every city-block or so. It wouldn't work well to have one huge street light for the whole town.)
When you get a fair distance away, it's just not powerful enough. This is due to the inverse square law.

However short distance wireless electricity is feasible, particularly when it exploits near-field effects of an antenna.
So for example you could power a laptop computer on your desk without plugging it in. However, the desk needs to be plugged in, and when away from your desk you'll be running on batteries only.

Answer 2

"Wireless power transmission is not a new idea, but to do so in an efficient way typically requires a directed beam like a laser or microwave (see Microwave power transmission). William C. Brown demonstrated in 1964 ," Considering this is not a new thing and has been in developments for so long I'm guessing not anytime soon . Although major break through have been recorded since the first person has come up with the idea , a system like this still has not been public tested , and or audited for potential downfall.

Answer 3

It's already available to the public, but only for small, low-voltage appliances. At home, I have an electric toothbrush that charges via induction without wires, but has to be sat on a base station. I also have some lights that charge up when they are sitting on a special plate but have no fixed position on the plate for charging. It is most likely that wireless power will replace the dozens of mains adapters for phones, ipods, torches, etc. If you want high-voltage wireless electricity, you are really looking at a lightning bolt!

Answer 4

It was pretty much banned on a realistic basis for everyday use. A scientist (I can't remember his name) created the same experiment to broadcast power wirelessly around the world. He owed an electric company. The capacitor blew up and had 300 acres of trees laying sideways away from the center of the site. The ground melted and turned to green glass *from grass and sand* underneath the ground. Lightening occurred all around the world at the same time. I would like to prove this as one of the worlds blunders NOT to be attempted again anytime this century.

Answer 5

At work, we heat metal bearing races with magnetic induction heaters. They will bring 10 pounds of metal from room temperature to 400F in less than 2 minutes.

But they also kill cell phones, watches, and credit cards in the operators pockets.

Looks like wireless electricity will have same effects.

Answer 6

I have seen stories about using magnetic induction in homes. My concern is how will it affect devices such as watches and pacemakers.

Answer 7

Never.

If Tesla's experience of 1918 can be reproduced and controlled, it will be used as a weapon though.

Answer 8

fly a kite during a thunderstorm.

It will be available all too quick.

Answer 9

The same time that flying pigs will be readily available.
