The constant influence of chemicals (mostly petrochemical based) in our water, air and food are a far more likely source of increased cancer rates than RF in the air. Burned chemicals don’t simply disappear from the gas tank. These are known to increase cancer rates. Rather than “suspect” a source that gives inconclusive results we should begin working to correct the known “evils.”

A path away from our petrochemical dependence is the EV. Unlimited range electric vehicles = clean, quiet, efficient, inexpensive private and mass transit. It is not beyond the petrochemical industry to raise doubts about competing technologies in an attempt to maintain its hold on our society. We can listen to those fears or boldly move forward away from chemical dependency.

I agree. I think about the same things every time I read about such a technology.

You should be particularly careful when advocating wireless energy transfer, because so far there have been very few studies about its effects on human health.

If we take into account the ones about cell phones and/or WiFi, the conclusions are mixed. If we consider that some of those studies have been sponsored/influenced by the cell phone companies, then we end up with a probably negative outcome for human health.

It is not a matter to be taken lightly. Cancer rates have skyrocketed during the last decades because of our lifestyle. And the industry is not regulated enough to protect us from dangerous products…

There are already EV wireless chargers for private use that are 97% efficient: http://gas2.org/2011/08/03/evatran%E2%80%99s-wireless-ev-charging-hot-spot-boasts-97-efficiency/ Google is testing them as well. http://cleantechnica.com/2011/03/24/google-tries-wireless-ev-charging/ Another step, to put such devices at more public charging stations, stops and red lights would require manufacturers install the necessary pick ups on a sufficient number of EV. The last step would be EV charging lanes on highways. You are already exposed to countless RF energy. Manufacturers claim the energy is harmless although who you trust is another matter. Microwaves are another method of wireless energy transfer but this is not completely harmless.

I have looked at several wireless energy transfer systems. Researchers are getting between 80 to 90% efficiency. Tuned transfer can cover remarkable distances but this system would require the least separation as the tires are already in contact with the road. Studies have shown that transmitting energy would be a cheaper method of EV adoption than by using exclusively batteries. http://www.greencarcongress.com/2010/02/nrel-study-finds-that-a-dynamic-plugin-vehicle-could-be-a-promising-technology-pathway-for-costeffec.html So I would love to see your envelope.

Not gonna pass the back of the envelope calculations test. But thanks for thinking out of the box though.

This doesn’t seem to be too realistic.

Inverters under the road? It would take immense amount of money to convert even city roads to allow this working method. That would only be cheaper if only small road sections would need to be converted. In this case, all cars would still need to retain sizable batteries and there would be a very high energy RF transfer during the short sections (for the same charge) which I wouldn’t trust to be harmless.
