Hi,

I want to power a 3 mm typical (common) infrared LED via wireless electric transfer using NORMAL INDUCTION (NOT RESONANCE).

- If I use approximately 1.5 cm diameter coil with at least 15 windings for both transmitter and receiver, how far can the two coils be before the light dims to only 70% of the maximum LED light luminosity (i just want to get an idea of the max range of induction energy transfer - seems hard to find on internet.)

- can i get smaller diameter and lesser windings for above case if the distance i want is less than 12 cm??

- resonance induction --> it's a patented technology is it??

- will such magnetic field interfere with devices such as mobile phone's circuitry??

- is it perfectly safe for people if the coils are sealed??

Thanks for any suggestions and information Witricity: witric power.
