Portee,
Zenn may make a big move soon. All the scuttlebutt on the web is that EEStor is close to production (not just a prototype) of their electrical energy storage units (EESUs). And check out this comment from the management discussion and analysis document! (my bold)
"In the three months ended June 30, 2009, the Engineering group re-evaluated a number of Lithium based power-packs for inclusion in its solutions. As a result of these efforts, the Company does not see Lithium as an economically viable power source for its offerings, particularly with the progressed state of development of the EESU as indicated by EEStor."
That means that Zenn is now placing all their bets on the EEStor module. Zenn has always been pretty much an all or nothing EEStor lottery ticket, but this pretty much makes it official. And this is as close as I've seen to an official statement that we may be winners!
GL,
