NATION | Could widespread wireless transmission of electricity be just a few steps away? Well, the dream of Nikola Tesla to power electrical devices without cords may be one step closer to reality in WiTricity.
A company called WiTricity has developed a device called Prodigy. This system involves a transmitter and receiver boxes with LED lights. When the base unit is switched on, it creates a resonating magnetic field that can be picked up by the satellite boxes, and converted into electricity, lighting the bulbs. The signal may be transferred through non-metallic materials. Currently, the system is limited to transmission distances of around one foot. WiTricity has developed a repeater box, which allows for greater distances to be achieved.
The company believes similar technology, when scaled up, could power home electronic devices and home lighting. On a still-greater scale, such technology could be used to drive electric cars, without the need to plug them into an outlet. Pro
