Wireless electricity? It's here

Perfectly safe eh? Our bodies run on electrical signals, including our heart. In addition, the claim that it&#x27;s as safe as wifi assumes the power levels will be the same. Charging a car and catching an internet signal requires vastly different power levels. And one is over 9000<p><a href="http://en.m.wikipedia.org/wiki/Wireless_electronic_devices_and_health" rel="nofollow">http:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Wireless_electronic_devices_a...</a><p>Here is an overview of studies of slightly stronger radiation from mobile phones:<p><a href="http://en.m.wikipedia.org/wiki/Mobile_phone_radiation_and_health" rel="nofollow">http:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Mobile_phone_radiation_and_he...</a><p>The World Health Organization&#x27;s conclusion is that radiofrequency electromagnetic fields are &quot;possibly carcinogenic to humans (Group 2B), a category used when a causal association is considered credible, but when chance, bias or confounding cannot be ruled out with reasonable confidence.&quot;<p><a href="http://www.who.int/mediacentre/factsheets/fs193/en/" rel="nofollow">http:&#x2F;&#x2F;www.who.int&#x2F;mediacentre&#x2F;factsheets&#x2F;fs193&#x2F;en&#x2F;</a><p>Our brains run on electrical signals and are affected: <a href="http://www.telegraph.co.uk/health/healthnews/8340817/Mobile-phones-do-affect-brain-activity-study-finds.html" rel="nofollow">http:&#x2F;&#x2F;www.telegraph.co.uk&#x2F;health&#x2F;healthnews&#x2F;8340817&#x2F;Mobile-...</a><p>And finally, the assumption of safety above is that all people are roughly the same in their sensitivity.

What&#x27;d happen if you had a pace maker? Would it not mess with that potentially?

Tesla came up with this about a hundred years ago[1]. Seems pretty silly to act like it&#x27;s new all the sudden.<p>[1] <a href="http://en.wikipedia.org/wiki/Wireless_power" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Wireless_power</a>
