I doubt that he's doing anything like that. But all kinds of bad things can nuke a promising product between the lab and the marketplace. The development works in the lab model, but doesn't scale to a useful size. They can't find a way to produce it practically or affordably. It needs some kind of material that only comes from politically unstable parts of the world. A couple of prototypes blow up or burn, and the negative PR kills it (see: Ford Ecostar and the sodium sulfur battery*). Something else better or cheaper comes along before it's developed, and grabs the potential market. They're working with public funding, and some rich person sees a threat to his established market and lobbies the government to take the funding away (see: Koch brothers and solar energy). Or new politicians come along and take it away just because that's what they do (see: Ronald Reagan moves into the White House and immediately has the Carter PV panels ripped off its roof). The market changes and the invention becomes a white elephant, at least in the short term (see: cheap fuel and late 1970s - early 1980s EV and battery research). The developers team up with larger partners who argue over goals, push out the originators, bring in their own guys, and run it into the ground (see: Renaissance Cars Tropica / Zebra / Xebra). Or the inventor sells the rights to some large corporation which then sits on it, or sells it someone else who sits on it (see Ovonics). The list goes on and on and on. The system doesn't like change, and wires around it in any way it can. Even when the system works, practical application can take a long time. The first experimental lithium ion batteries were developed in 1980, IIRC. The first commercial lithium ion battery was released 11 years later. Lion didn't become all that common in (expensive) portable electronic gadgets until at least 1992 or 1993. FWIW, the first Lion-powered EV I know of was the Altra EV, a rather sizable wagon based on a Japanese-market Nissan. Nissan built 200 of them between 1997 and 2001. Some of our older California correspondents may remember the Altra. I wouldn't be surprised if Bruce Parmentier got to drive one. ;-) Altras used Sony lithium-cobalt and Hitachi lithium- manganese modules. The range was stated as "up to" 120 or 140 miles, with 70- 100 miles considered more realistic. The range numbers sound a lot loke the Leaf's, don't they? It seems as if 20 years haven't really changed much in that respect, they've mostly just brought the price down to affordable levels. *Ford developed the sodium-sulfur battery in 1965, but they didn't actually use it in an EV until 1991. That was the Ecostar van. Two of the pre- production samples caught fire while charging. That made a good excuse to abandon the project.
