Sceptical of EEStor

While the green-leaning venture capitalists at Kleiner Perkins look like they own about 20 percent of buzzy energy storage firm EEStor, Vinod Khosla — an affiliated partner at Kleiner and head of his own firm, Khosla Venture — appears to have a different perception of the high-profile startup. He is “somewhat skeptical of this particular company [EEStor],” and while he believes that the science in EEStor’s patents are possible, these types of “radical approaches…are in the domain of a hope and a prayer,” he wrote in an article for Grist this weekend.

Given Kleiner hasn’t exactly been embracing a public link to EEStor as of late, and the startup has yet to produce a commercial product, missing its projected deadlines, it’s interesting to hear Khosla’s impression of the company. His skepticism of it is by no means uncommon — EEStor is one of the most controversial companies we’ve written about, eliciting many positive and negative comments about its supposedly revolutionary claims.

Khosla didn’t go into much detail about his skepticism of EEStor, or why he doubts the company.

Weir = con-man ?

maybe they are doing it to create more hype ? There are too many mixed deadlines to take them seriously .... Polywells might also one day change the future but we never see things like this in the Polywell community.

Lockheed never says anything public about their relationship with EEsstor or if they have actually seen a working EESU, maybe Zenn is in on the stunt and both companies/agencies are helping each other out.

ZENN could stand some help, according to this article by Reuters.
Zenn shares skid as economy, oil prices dent sales

You're on to them. There's benefit to all 3 parties even if all 3 know the technology will *never* work. Even the CIA benefits, in that it diverts resources, attention and exposes the anonymity of their spook adversaries; Resources that might otherwise be used in more worthwhile endeavor.

Here is a blog that follows the company that interviewed Weir. Seems that the interview was not necessarily in line with stock market trading rules, but no fall-out yet. The problem being that institutional investors were privy to information not widely available to the general investing public. That is, trading stock based on insider information is generally not cricket. Others might have a totally different view, "pump and dump."

EESTOR looking less like scam and more like really maybe. They are taking on vendors and spending their money.

This contract is for voltage step-down converters - from about 3500V to about 600V. I guess ZENN is using high voltage motors which makes sense.

It doesn't give the size of the contract. It could be as little as $5K. Especially if the converters shown are the ones that are going to be used. Not much power handling capacity there.

If they were buying $1 Mn in converters I'd be impressed. It would be nice to know the converter specs.

Come on. Due diligence questions are not hard to ask.

A lot of bloggers are assuming that it will be the down converter that they have on the market.

But there is no real reason to think they would not build something new to spec if the money's right.

10 KW @ $1/watt = $10K. Might be as little as $.50/watt if it is a production item.

So the question is: what is the contracted number of power supplies?

So they have a contract. So what? Is it like:

1. Two or three supplies for a prototype.
2. Volume delivery at a rate of x per month at a price of y starting TBD.

There always seems to be a little something off on EEStor/Zenn announcements.

Yes. Unfortunately for the curious the EESTOR operation is not public domain. But then, who among us would really want it to be?
