Freevolt technology collects energy from ambient radio waves

In the spring of this year, we wrote about the device from the company Labs Nikola, which is the case for the smartphone, the ability to collect external radio frequency energy and nourish her ​​phone battery. 

Tech-spider: Freevolt technology collects energy from ambient radio waves

Now, Lord Paul Drayson businessman, who is a former British minister of science, technology introduced Freevolt, allows you to direct the "free" radio existing digital networks for the supply of various low-power devices. The device, developed by a British company Drayson Technologies, is a multi-band antenna and a rectifier. Antenna absorbs the energy of several radio frequencies at the same time. 

The rectifier converts AC power to DC any orientation. It uses only the "free" waves, which do not carry the payload. It is interesting that the presentation Freevolt and personal recorder of air pollution CleanSpace, which uses this technology, was held in a theater in London Royal Institute, where in the XIX century lectured author of the first electric motor and the founder the doctrine of the electromagnetic field is Michael Faraday.

 However, experts met to develop a fairly restrained, because it is not clear whether Freevolt feed more powerful devices.
