Wireless Electricity Is Not A Futuristic Concept Anymore

Wireless technology is advancing every day, so it was only a matter of time before someone developed a way to send electricity through the air without wires or cables to carry it. Scientists have found a way to transfer that energy, and are working now on ways to make it feasible for use in our homes and lives.

Nikola Tesla Thought of It First

In the late 19th century, Nikola Tesla came up with the theory of transmitting electricity through the air wirelessly via a magnetic coil called the Tesla Coil. He had a tower constructed in Shoreham, Long Island in 1901 that was designed to pull electricity from Niagara Falls and broadcast it out to the world. Unfortunately, it was never completed and was dismantled by his mortgage holder in 1917.

Wireless Electricity is Transmitted by a Magnetic Field

In 2007, a Massachusetts Institute of Technology (MIT) professor, Dr. Marin Soljacic, PhD wanted to find a way to keep his wife’s phone from awakening him in the middle of the night when the battery died. He and his team of scientists discovered a way to transfer electricity wirelessly for seven feet and light a 60-watt bulb. It all happens via a process known as inductive coupling, which uses magnetic resonance to send and receive signals.

There is No “Shock Value”

Since the electricity is produced via vibrations, there is actually no electricity being sent through the air. You can’t be shocked by coming within close proximity to the transmitter or responder units, so it is completely safe for humans and animals.

Wireless Electrical Devices Are Already Available

Small inductive coupling recharging units for small rechargeable devices, such as cell phones, are already available. The downside is that they can only transfer power for a few inches. The future could bring pads large and powerful enough to power an entire house or recharge an electric car.

The Future of Wireless Electricity

The challenge facing scientists is to increase the distance they can efficiently transfer power. They are now working to develop AA-sized wirelessly rechargeable batteries. Think of the convenience of having your Wi-Fi devices recharge constantly, without having to be plugged in. Wireless electricity could theoretically make batteries obsolete, as power would be available wherever you go.

If you can, imagine a world with no power lines overhead or under your feet and without billions of batteries rotting away in landfills, polluting our groundwater. The technology to transfer power wirelessly is already here, and that mess of wires underneath your desk may soon be a thing of the past.
