I smell BULLSHIT.
They are publicly traded ... sure, but it's not the NYSE, and doesn't look to move there anytime soon. For that matter, it's an exhange I've never heard of.
They've claim to have built working engines that have been tested on a dyno... so why is every picture on their website computer generated or drafted? Where are the real pics? Where are the real dyno sheets? Why does their website say it has 6 cylinders when their pictures clearly show 12? Why does their website look like ass - especially the logo? Seriously, we get better quality here on a volunteer budget.
IMO this is a company that dug up an old idea that wasn't very well known and chances are didn't work well, dressed it up with a bunch of modern day buzzwords & technologies, made some outlandish claims, and will now try to raise a bunch of money so that the board of directors (and his brother) can run off to some small island in the gulf of Mexico and languish in luxury for the rest of their lives.
How this thing works is actually pretty simple, but there are some bigtime inherent challenges in the design, and the drawings they have posted show nothing to combat the problems.
If you want revolutionary engines with no crankshaft, IMO, go buy a Mazda Rx series with a rotary in it, these work for real.
