ZENN electric car is Dead and EEStor’s EESU is Nowhere to be Seen.

ZENN is Dead and EEStor’s EESU is Nowhere to be Seen.
Canadian electric vehicle maker ZENN Motor Company is to stop production of its LSV (Low Speed Vehicle) electric car after the launch of its final model later this month.
The ZENN car was supposed to be the first vehicle to use the much anticipated “EESU” energy storage device supplied by American company EEStor. The EESU is a (yet to be seen) ultra-capacitor supposedly capable of providing enough capacity for 400 kilometers (250 miles) of range at 125 km/h (77 mph) yet have the ability to recharge in an astonishing 5 minutes.
The EESU was supposed to be supplied to the ZENN motor group at the end of 2007. Almost two years later, and with ZENN investing $2.5 million USD into EEStor, ZENN has finally fallen over as a vehicle manufacturer, with the promised EESU nowhere to be seen.
Understandably, ZENN claimed poor sales led to their demise. They weren’t lying either: less than 500 vehicles had been sold since production began in 2006. While waiting for the EESU to arrive, ZENN’s car used sealed lead acid batteries instead, with lackluster results.
The lead acid version had a range of just 80 kilometers (50 miles), and being a Low Speed Vehicle it’s top speed was limited to just 40 km/h (25 mph) in order to comply with LSV laws.
ZENN Motor Company obviously put their trust in EEStor’s delivery times. They took a leap, believing (and investing) in EEStor’s promised exclusivity for ZENN vehicles. Sadly it was not to be.
As the months and years dragged on, EEStor released press release after press release promising that more milestones had been reached, and that production was always just a few weeks away.
Naturally the critics and skeptics had a field day with each new delay. One of the main criticisms has been that EEStor’s EESU won’t be able to hold a charge at the high voltage claimed. Skeptics report that a capacitor with such a high voltage & density would break down internally and short-circuit. It hasn’t helped that EEStor have not allowed their EESU to be independently tested and verified.
So what now for the ZENN Motor Company and it’s staff? ZENN reports that it will keep its factory open for the immediate future to service the existing sold vehicles and from here on, ZENN will change its focus to providing electric drive trains to major auto makers instead.
This strategy still relies on the eventual delivery of the EESU from EEStor. If the critics are correct, they should cut their sizable losses and give up now. If the critics are wrong however, then every auto maker in the world will be knocking on ZENN’s door in just a few weeks.

    “(Please freely repost this)

    This funding for the car companies was all “pay to play”, insider, self-dealing. The companies that were turned down had the exact same things in common:
    1. They did not pay hundreds of thousands to buy influence. This is on public record and can be investigation under lobby and cost filings.
    2. They did not make campaign contributions.
    3. Each of the reasons they were told they were turned down were violated with each of the companies that did get money.
    4. They were doing all of the work in the U.S. unlike those who did get the money.
    5. They had a car design and those who got the money were “thinking about doing a car design”.
    6. You could not draw a line from them to a politician or a person who made money or political gain unlike those who did get the money.

    Every one of the people that did get money got the “requirements” of the section 136 law waived or were in direct violation of the intent-of-the-law yet the DOE team for that money used those very same “requirements” to say that they would deny funding to those who had not contributed.

    It was a crooked set of deals and the regulatory, law enforcement and voters need to make some noise about this.”

    It is obvious that the oil mafia has a hand in this. The (so called) general motors electric car the “volt” is just an expensive piece of junk. It only stays electric for 40 miles before the gasoline engine kicks in. and that’s at 40 miles per hour or less. There were electric cars built over 100 years ago that could do that and they claimed 50 miles on a charge using primitive lead acid batteries. The volt is designed to turn people off to electric vehicles. However, I am glad they gave some money to Tesla to develop their car. I hope they can come through.
