Nikola Tesla (1856 - 1943)

“Nikola Tesla, the eccentric - and unbelievably under-rated - genius known as the ‘wild man of electronics’, was without doubt one of the greatest minds in the history of the human race.”

  • Born in Austro-Hungary (now Croatia) in 1856, Tesla constructed his first induction motor in 1883 and immigrated to America in 1884 - arriving in New York with worldly goods totaling four cents, a pocket full of poems, carefully worked calculations for a flying machine, and a head full of strange dreams.

  • Tesla began working with Thomas Edison, but the two men were worlds apart in both their science and cultures (the fact that Tesla's alternating-current concept posed a direct threat to sales of Edison's direct-current devices probably didn't help) and they soon went their separate ways.

  • Tesla invented the alternating-current generator that provides your light and electricity, the transformer through which it is sent, and even the high voltage coil of your picture tube. The Tesla Coil, in fact, is used in radios, television sets, and a wide range of other electronic equipment - invented in 1891, no-one's ever come up with anything better.

  • Letting Tesla go wasn't the brightest thing Edison had ever done, though - George Westinghouse promptly snapped up the patent rights to Tesla's alternating-current motors, dynamos, and transformers. The buy-out triggered a power struggle which eventually saw Edison's direct-current systems relegated to second place, and the DC motors installed in German and Irish trains only a few years before, rendered obsolete.

The idea of wireless electricity has been around since the early days of the Tesla coil. But thanks to a group of MIT scientists, "WiTricity" (as these scientists call it) is now one step closer to practical reality.

Demonstrating the ability to power a 60-watt light bulb from a power source seven feet away without wires might not seem like the most impressive of feats, but the technology behind it has massive implications for how we live our tech-filled, power-hungry lives. Imagine a day when your laptop, MP3 or player are constantly charged by power sent through the air via an electromagnetic field.

How it would look and work in your office or bedroom



A Starbucks where you can use the restroom for free, use their Wi Fi for free and get a quick charge for your cell phone all without buying a “venti white chocolate mocha” for $4.00 plus tax.

Splashpower Ltd. is a United Kingdom-based company founded in June 2001. It has been attempting to develop technology for wireless charging of portable devices such as mobile phones, personal digital assistants, mp3 players and cameras. Their system works through electromagnetic induction, adding a free positioning induction loop (at the “SplashPad") to the conventional fix induction loop at the wall plug (used to shift between AC and DC currents). According to the company's claims, rechargeable devices equipped with a small Splash Module are placed upon a mouse pad-sized SplashPad and have their batteries recharged at a normal rate.(Wikipedia)

  • Significant decluttering of office space

  • No need for meter rooms and electrical closets.

  • Reduction of e-waste by eliminating the need for power cords

  • Need more light in your office, no need for electrician. Simply place the lamp where ever you need it.

  • Need for standardization and adaptation. So no overheating occurs because of different voltages.

  • Retrofitting old equipment or purchasing new equipment could become a very expensive endeavor

  • possibility of “energy theft”. Wi Fi, someone can be using your internet or your power.

Incremental or disruptive
Incremental or Disruptive

  • We believe wireless electricity incremental because it was innovated at the end of the 1800’s and only last year it was improved to a new technology.

  • We can also say that it may become disruptive because if a strong enough product is developed it will wipe out the demand for chargers. Therefore charging will become universal.

    What it will replace

  • Batteries

  • Cords
