Energy from Radio Waves

Energy from Radio Waves

Being able to convey electrical energy effectively wirelessly from device to device has long been the dream of many engineers in the world since the days of Nicola Tesla, though unfortunately until recent years this has proven a particularly difficult task as any wireless transfer of energy generally can be highly dangerous for some people – and even potentially fatal if done incorrectly. There are ways around this, however, and by bypassing the standard concept of energy transfer in terms of pure electrons or magnet-to-magnet manipulations as found in some current devices using a “wireless” transfer method (such as device docks that will allow special batteries to charge on top of them simply by laying the battery on it) and using radio waves as an energy carrier engineers have successfully developed a method of conveying “wireless power” over ranges of up to 10 meters (roughly 30 feet) from a basic transmitter inserted into a wall socket.

The transfer works by first housing a specialized magnet attuned to the frequency generated by the transmitter within a battery or other power source to fuel the desired device. As the magnet receives signals from the transmitter it will vibrate utilizing the energy collected from the received signal, creating minute fluctuations that can be harnessed by the power source and then converted into usable electricity internally in the device. The result is the potential to have a device ranging anywhere from a simple light bulb to even a complex mobile phone or computer that can operate with no power connection and even recharge power over time for use away from the transmitter by storing excess energy within a battery pack.

Currently this method for wireless energy transfer is being used in some water processing plants throughout the world, allowing for an ultraviolet (UV) sterilization light to be sealed within a purification tank with no external wires or other mechanical connections that could potentially corrode and otherwise damage the purification process. Energy is simply sent from an external source into the sealed tank and the light operates essentially undisturbed up to the point it needs to be replaced with a new bulb. In terms of commercial application in residential homes production is still being finalized for distribution to consumers globally, though many people anticipate that this form of power transmission will be available for consumer use within 2 to 3 years and will be perfectly safe for consumer use.
