According to a recent article, http://www.reuters.com/article/earth2Tech/idUS374977681620090923, Zenn has decided to stop making cars. Instead, it will focus on marketing its ZENNergy drive system to other auto manufacturers. Kudos to those on this forum (Mos) that foresaw this move.
As Mos insisted, Zenn will make much more money selling the drive system than the car.
This has interesting implications for the EEStor technology though. With their ultracapacitor (small prototype) undergoing UL testing and Zenn announcing a major production shift, we could be tempted to conclude that the elusive EEStor unit is REAL!
Zenn's announcement may also mean that there will be a delay in production automobiles with the ZENNergy drive system. Will Zenn actually be a roadblock to wider adoption? Will one or more major auto companies jump at the ZENNergy drive system? Is EEStor contractually obligated to use Zenn as a middle man? How easily can the EEStor technology be adapted to other applications (laptop batteries, Copper Tops, UPS, Off-peak grid storage, etc.)?
