Marin Soljacic, an assistant professor in MIT’s Department of Physics and Research Laboratory of Electronics had a thought. Quite often we forget to recharge our cell phone, and when it is about to die it emits an unpleasant noise. “Needless to say, this always happens in the middle of the night,” he said. “So, one night, at 3 a.m., it occurred to me: Wouldn’t it be great if this thing charged itself?” He began to wonder if any of the physics principles he knew of could result in new ways of transmitting energy.
MIT is known for being at the forefront of new technology. Marin Soljacic and researchers there have made a 60 watt light bulb glow via wireless energy 7 feet away. Wireless energy!. This is significant. We are now closer to having small gadgets run without having to be plugged in somewhere. This technology works by using tuned waves – setting the recharging device and the same frequency. Much work has yet to be done, but either way how cool is this?
