Let me just say this. I am not impressed.

>> (Business 2.0 Magazine) -- How much money could you make from a
>> technology that replaces electrical wires? A startup called
>> Powercast, along with the more than 100 companies that have inked
>> agreements with it, is about to start finding out. Powercast and its
>> first major partner, electronics giant Philips, are set to launch
>> their first device powered by electricity broadcast through the air.
>> It may sound futuristic, but Powercast's platform uses nothing more
>> complex than a radio--and is cheap enough for just about any company
>> to incorporate into a product. A transmitter plugs into the wall,
>> and a dime-size receiver (the real innovation, costing about $5 to
>> make) can be embedded into any low-voltage device. The receiver
>> turns radio waves into DC electricity, recharging the device's
>> battery at a distance of up to 3 feet.
>> Picture your cell phone charging up the second you sit down at your
>> desk, and you start to get a sense of the opportunity. How big can
>> it get? "The sky's the limit," says John Shearer, Powercast's
>> founder and CEO. He estimates shipping "many millions of units" by
>> the end of 2008.
>> For years, electricity experts said this kind of thing couldn't be
>> done. "If you had asked me seven months ago if this was possible, I
>> would have said, 'Are you dreaming? Have you been smoking
>> something?'" says Govi Rao, vice president and general manager of
>> solid-state lighting at Philips (Charts). "But to see it work is
>> just amazing. It could revolutionize what we know about power."
>> So impressed was Rao after witnessing Powercast's demo last summer
>> that he walked away jotting down a list of the industries to which
>> the technology could immediately be applied: lighting, peripherals,
>> all kinds of handheld electronics. Philips partnered with Powercast
>> last July, and their first joint product, a wirelessly powered LED
>> light stick, will hit the market this year. Computer peripherals,
>> such as a wireless keyboard and mouse, will follow in 2008.
>> Broadcasting power through the air isn't a new idea. Researchers
>> have experimented with capturing the radiation in radio frequency at
>> high power but had difficulty capturing it at consumer-friendly low
>> power. "You'd have energy bouncing off the walls and arriving in a
>> wide range of voltages," says Zoya Popovic, an electrical
>> engineering professor at the University of Colorado who works on
>> wireless electricity projects for the U.S. military.
>> That's where Shearer came in. A former physicist based in
>> Pittsburgh, he and his team spent four years poring over wireless
>> electricity research in a lab hidden behind his family's coffee
>> house. He figured much of the energy bouncing off walls could be
>> captured. All you had to do was build a receiver that could act like
>> a radio tuned to many frequencies at once.
>> "I realized we wanted to grab that static and harness it," Shearer
>> says. "It's all energy."
>> So the Powercast team set about creating and patenting that
>> receiver. Its tiny but hyperefficient receiving circuits can adjust
>> to variations in load and field strength while maintaining a
>> constant DC voltage. Thanks to the fact that it transmits only safe
>> low wattages, the Powercast system quickly won FCC approval--and $10
>> million from private investors.
>> Powercast says it has signed nondisclosure agreements to develop
>> products with more than 100 companies, including major manufacturers
>> of cell phones, MP3 players, automotive parts, temperature sensors,
>> hearing aids, and medical implants.
>> The last of those alone could be a multibillion-dollar market:
>> Pacemakers, defibrillators, and the like require surgery to replace
>> dead batteries. But with a built-in Powercast receiver, those
>> batteries could last a lifetime.
>> "Everyone's looking to cut that last cord," says Alex Slawsby, a
>> consultant at Innosight who specializes in disruptive innovation.
>> "Think of the billion cell phones sold last year. If you could get
>> Powercast into a small percentage of the high-end models, those
>> would be huge numbers."
>> Could Powercast's technology also work for larger devices? Perhaps,
>> but not quite yet. Laptop computers, for example, use more than 10
>> times the wattage of Powercast transmissions.
>> But industry trends are on Shearer's side: Thanks to less
>> energy-hungry LCD screens and processors, PC power consumption is
>> slowly diminishing. Within five years, Shearer says, laptops will be
>> down to single-digit wattage--making his revenue potential even more
>> electrifying.
