Ultra Cap Wrap

The little company in Texas with the big hope has peeked out of the woodwork again.

Here is part of the press release:

"The first commercial application of the EESU is intended to be used in electric vehicles under a technology agreement with ZENN Motors Company. EEStor, Inc. remains on track to begin shipping production 15 kilowatt-hour Electrical Energy Storage Units (EESU) to ZENN Motor Company in 2007 for use in their electric vehicles.

The production EESU for ZENN Motor Company will function to specification in operating environments as sever as negative 20 to plus 65 degrees Celsius, will weigh less than 100 pounds, and will have ability to be recharged in a matter of minutes. (clip)

EEStor, Inc. is dedicated to the design, development, and manufacturing of high-density energy storage devices. Utilizing revolutionary ultra capacitor architecture and environmentally friendly materials the EEStor, Inc. EESU will compete against all existing battery technologies.

The EESU is capable of microsecond recharging and millions of 100% charge/discharge cycles. The technology is affordable and designed for versatile "racked and stacked" configurations."

If EEStor can provide the radical energy storage capability it says it can, there will be a plethora of GM Volt announcements.

Just think about it.

15 Kwhs will give you a range of about 60 miles with a weight of 100 lbs. That weight is equal to about 14 gallons of gas. So the energy density ratio per pound is equal to 1/4 of the energy punch of gasoline. But, the energy ratio per cubic foot is approximately 1/2. So the size of a 240 mile electric gas tank would only be twice as big as a regular gas tank and it would be perhaps four times heavier.

Considering that a plug in hybrid would only need the 15 Kwh size, the energy storage increase in weight is less than one skinny pre-teen. That difference can easily be made up with the use of advanced composite materials and other reductions in weight achieved with the elimination of the transmission and the use of a much smaller engine.

With a platform consisting of in wheel electric motors and capacitors imbedded in a new advanced composite chassis, powered by a highly efficient internal combustion engine or micro turbine running at optimum efficiency and speeds, a whole new kind of transportation device becomes a reality.

In the meantime, a huge market for affordable energy storage will also develop in the electric sector.

With cost effective energy storage, you can say goodbye to the need for more coal plants, because utility companies will be able to run their plants heavier at night.

With cost effective energy storage, you can say hello to more off grid homes.

With cost effective energy storage,

We can kiss defending those Mideast oil supplies goodbye,

And run our transportation system on West Texas wind

and Southwest Texas solar.

We can also save our corn.

For eating.

Hello Oz,

I see that you know about Peak Oil. What I don't see in the discussion I just read is an awareness of Maximum Renewables. This might be a pretty tall order; but, for someone as serious about making the world a better place as you are, it might not be too much trouble to look at, especially at the section on Maximum Renewables. This is a long paper, but it is summarized in only ten pages at

Also, if you like what you see at, we could link to each other's websites.

This is exciting. It looks as though this company can really make a difference if given a chance.

I so appreciate having the easy access to this info - with help from Earthfamily. With it comes hope. Thanks.
