Wireless electricity

[Alex]

Pretty cool. Three comments/questions.

1) How can you talk about wireless electricity without even a shout out to Tesla. That man was a kook in his later years but he had big ideas.

Then two comments on this paragraph:

Magnetic coupling is particularly suitable for everyday applications because most common materials interact only very weakly with magnetic fields, so interactions with extraneous environmental objects are suppressed even further. "The fact that magnetic fields interact so weakly with biological organisms is also important for safety considerations," Kurs, a graduate student in physics, points out.

1. If you've been intrigued by those "magnetic healing bracelets" sold via infomercial. Keep in mind that bold paragraph.

2. While biological entities don't interact strongly with magnetic fields, electrical and other magnetic systems do. I know it is maxed on certain frequencies but what kind of re-engineering (if any) of all the other electrical/magnetic things in our homes would be required?
