Stormbringer, I thought I would share that company that you recom investing in. The guy is a visionary person, and it is reality, but is not feasible for the average income American right now, I really can see no reason to invest right now unless the government ordered a bunch of those aircars (military landspeeders? Way too cool!). Give me some info on their robotics dept. if you do not mind.
Now that Rotary engine could have great applications if someone were to design an easy do it yourself kit for installing in an automobile. Sort of like my old 86 Toyota P/U I used to own, came with the 22R 4 cyl (one of the best 4 cyl engines in the world!). Some companies had a kit where you could yank out the 22R and install a small journal 327 V8 engine in it. Talk about a mini P/U with a LOT of HP and torque! BTW folks, for all you non automotive types, back in the 60's Beach Boy Corvette Summer days, most American sports cars used a small journal 327 engine until Detroit switched over to 350 and 427 V8s.
