Nokia is not what it used to be anymore, but the company is looking to more attention by developing a cellphone which will be recharged wireless. The prototype Nokia phone which recharges without wires is only in early-stage development, but initial lab experiments have shown that wireless power distribution is possible. Intel has demoed that you can beam electricity a few feet away and they powered a tiny light bulb, but Nokia is looking to take this a step further and power their cellphones using wireless electricity.

This merit should be attributed to Nikola Tesla (one of the most brilliant minds ever) as the scientist managed to send 100 million volts over a distance of 26 miles in order to lit 200 light bulbs and one electric motor. Please note that this occurred in 1899, and nobody knows how the hell did he do it.

Wireless power will be revolutionary and will change our devices of the future, and now thanks to Nokia, we could harvest radio waves and convert them into electricity. Nokia made a prototype cellphone which can do that, but this is in early development. A problem is the fact that they don’t know where the wireless waves are coming as there are TV, radio, and mobile systems’ waves out there, but their system catches a part of the waves, then converts the electromagnetic energy into electricity which recharges the phone’s battery.

According to experts, it’s not possible for electromagnetic energy to offer enough power for an entire household or office, but it should be enough to power most devices. Nokia says that they can catch 5 milliwatts over the air, but scientists should find a way to harvest 20 milliwatts soon, and 50 milliwatts as the technology advances.

Please note that this is not enough energy to power a cellphone, but the technology will recharge the battery while in standby mode which could mean that infinite power is on its way. If everything goes according to plan then Nokia will commercialize wireless energy transfer technology in the next 3 to 5 years.
