Why hasn't anyone developed the wireless electricity concept developed by Nicola Tesla?

Disclaimer: I have no Ph.D. in physics, but during my study, I had to attend a few semestres. Basically, nobody developed anything because while it could conceivably work, there are too many downsides. First of all, it's a big waste of electricity since you're radiating it in all directions. Second, it's unclear how you would charge people for it, since you can't measure who uses how much of it. And lastly, the effects on nature (and on humans) would probably be enormous. My prof said something about your hair sticking up in all directions because of the charge. The money argument is probably the main reason why almost nobody even as much as worked on the concept after Tesla. There's a page on wikipedia about Tesla: http://en.wikipedia.org/wiki/Nikola_Tesla

There are clubs and support groups that still design and build tesla coils and do experiments with them. If anyone had discovered or invented a viable commercial application for the technology you would see it marketed.

First it is impractical, loud, and expensive. There is also the problem of the electromagnetic fields generated from the Tesla Coil. It would cook all the unshielded electrinics within the area. They tried it in one city, fried the town's new generator. Then once you get past that, there woud be enormous ammounts of ozone created. This would be a health concern since some poeple have trouble breathing when arround it. Plus it just waists lost of energy that is radiates off in all directions.

The Russians have. Check out the link which shows the power station they built. http://fishki.net/comment.php?id=21722

There is an MIT group that's worked on transmitting power wirelessly using resonant couplers, which has some similarities to Tesla's work. The transmission efficiency of their device is not bad, around 60%. The range is only a few meters, though. http://web.mit.edu/newsoffice/2007/wireless-0607.html
