My Clean Break column today is a bit of an update on ZENN Motor, the potential of EEStor’s EESU, and an interesting comment about EEStor from Elon Musk, co-founder and CEO of Tesla Motors, who before becoming an entrepreneur had plans to enroll in engineering graduate studies and focus on ultracapacitors for vehicles. I also mention some interesting work on ultracapacitor materials being done at Queen’s University in Kingston, and talk about a new ultracapacitor bus operating in Shanghai that will be demonstrated Wednesday in Washington, D.C. (for another more detailed article on the ultracap bus check out this Technology Review article).
