It is difficult to believe but wireless electricity will be reality very soon. Powercast, a US based startup along with more than 100 companies (of which Philips is one of the major partner) are set to launch their first device powered by electricity broadcast through the air.
The basic idea works like this. A transmitter plugs into the wall, and a dime-size receiver costing about $5 to make can be embedded into any low-voltage device. The receiver turns radio waves into DC electricity, recharging the device’s battery at a distance of up to 3 feet.
Powercast says it has signed nondisclosure agreements to develop products with more than 100 companies, including major manufacturers of cell phones, MP3 players, automotive parts, temperature sensors, hearing aids, and medical implants.
