SAN FRANCISCO (AFP) - Intel last week showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets. Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than a typical laptop computer. Most importantly, the electricity was transmitted without zapping anything or anyone that got between the sending and receiving units."The trick with wireless power is not can you do it; it's can you do it safely and efficiently," Intel researcher Josh Smith said in an online video explaining the breakthrough. "It turns out the human body is not affected by magnetic fields; it is affected by elective fields. So what we are doing is transmitting energy using the magnetic field not the electric field."Examples of potential applications include airports, offices or other buildings that could be rigged to supply power to laptops, mobile telephones or other devices toted into them.

This is nice that more companies are getting involved in the wireless electricity revolution.
I know that a company called PowerBeam is also involved in the wireless era and they safely transmit energy through optical energy, instead of the copper wires and the electro-magnetic field.
By using optical energy they can send energy over long-range distances. Their device also has a safety system so that it shuts down if anything is close to the beam.
