Think of it as an energy-producing Bug Zapper. But rather than enticing and systematically destroying curious insects, this harvesting device gathers unused wave energy (ala microwave, Wi-Fi, satellite signals) and tunes them for useful applications. While gathering energy in such a manner has been done before, researchers at Duke University’s Pratt School of Engineering have […]

If a consortium of universities in the United Kingdom meet their goal, a technology to deliver internet communications will be created that could simultaneously be used to provide lighting and used as information displays. Li-Fi technology, or transmissions of internet communications that use visible light instead of radio or microwaves like current Wi-Fi, was the […]

A company called On-Ramp Wireless invented a technology that uses the same frequencies Wi-Fi network cards use, but modulates the signal in such a manner that it doesn't get distorted by noise, such as the surrounding networks. On the contrary, the Ultra-Link Processing technology can send signals to up to 45 miles and even uses much less power to do that, enabling savings in what concerns both energy and equipment deployed on the field by utilities.
