Unstealthing Kleiner Perkins' Fortu Powercell: Kleiner helped them seek DOE Battery Funds

Via yet another determined reader of, a new stealth Kleiner investment has come to light. This time, it required a FOIA request to the Department of Energy to learn the list of applicants for advanced battery development funds.

The complete list is a whos who of battery upstarts, established players and wannabes. It is currently located at

Since Kleiner has been so generous to me in regards to my numerous requests for comment on EEStor, it does make me chuckle a bit to be able to help uncloak yet another of their investments hiding in stealth. :-)

The DOE document lists Fortu Powercell Inc., as having an address of Kleiner Perkins Caulfield & Byers of 2750 Sand Hill Road, Menlo Park, California 94025. The POC listed is Mr. Alan Greenshields. From their website, it looks like this is a German company.

According to the forums website, RCGroups, Fortu uses a lithium chemistry consisting of Lithium-Cobalt-inorganic technology.

HHHhhhmm. Backing a German company for funds designed to grow a domestic battery industry. HHHhhhhmmm, not commenting on the EEStor investment. HHHhhhmmm.

Anyone at Kleiner care to clear any of this up for inquiring minds? Email:

Here is one of their patents.

UL in Receipt of Cert Request from EEStor

Lyle Dennis, founder of and, is reporting today that UL has begun working with EEStor on product certification. To what stage has this progressed is anybody's guess--maybe so far it's just at the request stage. But so far, here's the quote Dennis has obtained from UL:

"We have received a request to certify EEStor's product," said Priya L. Tabaddor, PhD, Global Energy Services, Underwriters Laboratories, Inc.

Additionally, back in July, I scored an interview with Jace Curtis from PTI, the company who ZMC contracted to validate the EEStor permittivity testing performed by Dr. Ed Golla. Dick Weir had indicated possibly working with them to prepare and/or complete UL certification testing with them. In the interview, Curtis provides good background on UL's relationship to OSHA, etc. Basically, companies can reduce the amount of time it takes to obtain UL certification by pretesting products before doing the actual testing. Also, according to Curtis, one of the last things a company does before releasing a product is to perform UL testing. It's on the right side of the gant chart.
