First, some numbers. The EESU could be a 52kwh pack that provides a 250-mile range and only weigh 280 pounds. ZENN now owns 10.7 percent of EEStor, up from 3.8 percent. Thanks to EEStor's recent permittivity announcements, ZENN has paid EEStor another $700,000.
Now, the intangibles. Clifford told GM-Volt.com that he sees the EESU prototypes "on a regular basis" and is waiting for a production prototype to be delivered by the end of this year. Clifford said that there is a "full production facility" at EEStor's pilot production plant. Possible in-vehicle application of the EESU could be around 600V, which Clifford says, "increases the drive efficiency, it makes the components somewhat smaller, and ultimately less expensive and obviously for mass commercialization." He couldn't say if he's actually seen one of the production EESU's, claiming non-disclosure agreements. He did promise, "absolutely," that demonstrations will take place in 2010.

If nothing else, this is all good hype maintenance. Thanks to Gordon S. for the tip!
