If the science is proven to work, then i would be able to assure with 99% that Zenn stock will appreciate considerably. Most likely scenarios:
1) Zenn puts out the vehicles on their own to Asia/Europe first where safety restrictions are not as stringent, and eventually N.A. follows suit under public outcry.
2) Zenn produces the drivetrains and licenses to the big three to produce.
3) Zenn realizes that they cannot do the production that they need, and they sell off/lease their rights for the up to 1,600 category. At this point they would have made a handsome penny, and they look at retrofitting.
4) Clifford/investors gets an offer that they can't refuse, and sells out to the big three.
For every scenario that I can think of there are many more alternatives, but if the science works, then you will be rewarded handsomely for your investment.
I have said all along, than in my professional opinion, this really has never looked like a scam to me, not in the least. You just don't act the way these guys have (apply for patents, set up Nas/TSX listings in motion, get investors with the reputations of those that are involved, get the type of people that are involved with their board, set up commercial production operations). To me it seems like any other hi-tech company that knows they have found something, and know that it will be sought after, and copied once they put it out there, so they are really trying to cover off all bases before moving forward.
