									         Wireless
        Electricity
By Gavriel Gavrilov & Alexander Zaltsman
                      The first mover and innovator
                                                                  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                           up the patent rights to                    ever done, though - George Westinghouse promptly snapped
    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 forgotten invention is reborn in
                     2007
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.

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)
         Pros                              Cons
• Significant decluttering of      •Need for standardization and
office space                       adaptation. So no overheating
•No need for meter rooms           occurs because of different

•Reduction of e-waste by           •Retrofitting old equipment or
eliminating the need for           purchasing new equipment

ever you need it.                  your internet or your power.
        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
