Intel's wireless electric power

Intel showed off a wireless electric power system. Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than typical laptop computer. The electricity was transmitted without zapping anything or anyone that got between the sending and receiving units.

intel claims that the technology could also be built into plugged in computer components, such as monitors, to enable them to broadcast power to devices left on desks or carried into rooms.

“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.”

Previous wireless power systems consisted basically of firing lightning bolts from sending to receiving units.
