MIT, ever on the quest for new technology, has now developed wireless power transmission without the use of wires. WiTricits uses what they refer to as “simple physics” based on two resonant objects on the same frequency which can be used to power light bulbs, laptops, etc. It even allows 40% efficiency when compared to current technology.

Although the researchers have been been working on the project for several years, they have finally gotten an actual workable model. In this case it involves two 2 ft. diameter copper coils, a transmitter attached to a power source, a receiver, and a 60 watt bulb. The light continued to shine even when obstructions, such as the research team themselves, were placed between the coils. There is no date on when this will become commonplace, but the news certainly brightened up our day.
