Tyler Hamilton of the Toronto Star and
website Clean Break has been digging around a very secretive company.
Asking them for information they said: "EEStor is not making public
statements at present time," company co-founder and chief executive
Richard Weir replied when the Toronto Star requested an interview via
email. "EEStor would also like to have you and your paper not publish
any articles about our company and the Toronto Star is certainly not
authorized to publish this response." which of course he published
instantly in Canada's biggest newspaper, BoingBoing style. . What they
are doing in Austin with their Kleiner Perkins Caufield & Byers money is
developing a "parallel plate capacitor with barium titanate as the
dielectric" or hypercapacitor as John recently coined. Says Tyler: "BusinessWeek
reported an interesting comment from Kleiner's John Doerr, who recently
spoke at a California event where tech VCs gather to make their
predictions for the year. Doerr reportedly referred to an investment in
an energy storage company he declined to name, calling it Kleiner's
"Highest-risk, highest-reward" investment." Tyler's source describes it:
(warning: if you continue reading you have to eat this post)
The batteries fully charge in minutes as opposed to hours.
* Whereas with lead acid batteries you might get lucky to have 500 to
700 recharge cycles, the EEStor technology has been tested up to a
million cycles with no material degradation.
* EEStor's technology could be used in more than low-speed electric
vehicles. The company envisions using it for full-speed pure electric
vehicles, hybrid-electrics (including plug-ins), military applications,
backup power and even large-scale utility storage for intermittent
renewable power sources such as wind and solar.
* Because it's a solid state battery rather than a chemical battery,
such being the case for lithium ion technology, there would be no
overheating and thus safety concerns with using it in a vehicle.
* Finally, with volume manufacturing it's expected to be
cost-competitive with lead-acid technology.
"It's the holy grail of battery technology," said my source. "It means
you could do a highway capable electric city car that would recharge in
three or four minutes and drive you from Toronto to Montreal. Consumers
wouldn't notice the difference from driving an electric car versus a
gas-powered car."
From his Star article:
Energy storage has long been the bottleneck for innovation, holding back
new energy-sucking features in mobile devices and preventing everything
from the electric car to renewable power systems from reaching their
full potential. Build a radically better battery at lower cost, experts
say, and the world we know will be forever transformed.
"There's been nothing big or disruptive, and we're due for it," says
Nicholas Parker, chairman of the Cleantech Venture Network, which tracks
investment in so-called clean technologies. He says energy storage is
one of the hottest areas for venture capital funding right now. "Right
across the board, better energy storage is essential."
Among EEStor's claims is that its "electrical energy storage unit" could
pack nearly 10 times the energy punch of a lead-acid battery of similar
weight and, under mass production, would cost half as much.
It also says its technology more than doubles the energy density of
lithium-ion batteries in most portable computer and mobile gadgets
today, but could be produced at one-eighth the cost.
If that's not impressive enough, EEStor says its energy storage
technology is "not explosive, corrosive, or hazardous" like lead-acid
and most lithium-ion systems, and will outlast the life of any
commercial product it powers. It can also absorb energy quickly, meaning
a small electric car containing a 17-kilowatt-hour system could be fully
charged in four to six minutes versus hours for other battery
technologies, the company claims.
According to patent documents obtained by the Star, EEStor's invention
will do no less than "replace the electrochemical battery" where it's
already used in hybrid and electric vehicles, power tools, electronic
gadgets and renewable energy systems, from solar-powered homes to
grid-connected wind farms.
"If everything they say is true, then that's pretty amazing," says
MacMurray Whale, an energy analyst at Sprott Securities and a former
professor of mechanical engineering at the University of Victoria. "To
do all of that is unheard of when you look at any other battery
technology out there."
