Wouldn’t it be neat to be able to have WiFi-like access to electricity? While wireless power is by no means a novel concept – Thomas Edison and Nikola Tesla already explored the possibility of wireless power - US-based company WiTricity claim that they have one of the most feasible methods of making the world a lot more wireless. In fact, WiTricity chief executive Eric Giler said in an interview with BBC that their technology may even be in use as early as one or two years from now. Of course all of this is dependent on a lot of factors – the cooperation of electronics manufacturers for one – but it seems that Physics is on WiTricity’s side as well.
The image above shows how coils connected to a power source and to devices facilitate the transfer of electromagnetic waves that are then used to power the device. The technology is based on the work of MIT physicist Marin Soljacic, and other scientists are giving it a thumbs up, not just for its feasibility or efficiency, but for its safety. According to Professor Peter Main at the Institute of Physics in UK, electromagnetic waves are harmless as long as they’re transferred at the right frequency. Unless you’re Wolverine, in which case you’re screwed. Here’s a demo of WiTricity’s technology:
Man, I hope I don’t die before all of these awesome technologies go mainstream. Except for Raytheon and their ray gun. I hope that project fails.

This technology will certainly put us on the fast track to population reduction. We are already well on the way with cell phones, wi fi, cell towers and all the other wireless things the telecoms and others have thrown at us that continues with no oversight or real testing. there is not one ongoing study on the effects of RF in the United States. In Europe thousands of studies seem to confirm the health nightmare we are cornering ourselves into. http://www.wirelesswatchblog.com
What’s Wrong With This Picture????
INTERNATIONAL STANDARDS FOR PUBLIC EXPOSURE TO RF/MW RADIATION
Exposure standards for public exposure to RF/MW radiation at cell phone frequencies in other countries is, in some cases, substantially lower than the US and Canadian limits (Table 1). The World Health Organization EMF Research Program is involved in a multi-year effort to review RF/MW health effects and make recommendations for exposure standards. In the interim, other countries around the world show considerable variation in what they consider safe exposure levels:
* Saltzberg (pulsed)………………………….. 0.1 microwatts
per centimeter squared
* China……………………………………………6.6
microwatts per centimeter squared
* Russia…………………………………………..10 microwatts per centimeter squared
* Italy……………………………………………..10
microwatts per centimeter squared
* Switzerland……………………………………4.2
microwatts per centimeter squared
* Auckland, New Zealand………………….50 microwatts per
centimeter squared
* United States ……..around 580 microwatts per centimeter squared
* Canada …………….around 580 microwatts per centimeter squared
There is substantial controversy among regulatory agencies in the federal government over the RF/MW exposure standards now in effect. A growing body of scientific evidence has linked RF/MW exposure to biological effects and health effects at levels lower than current FCC RF/MW standards allow. With respect to pulsed RFR, amplitude-modulated RFR and chronic low-level exposure there is uncertainty about risk, and no presumptive assurance or
warranty of safety can be made (see FDA and US Government Radiofrequency Interagency Working Group comments above).
