Mark, Welcome to I-hub. I will attempt to answer your question although I am not sure what you mean by uncertain terms. 1. There have been no independent tests done on any product nor has there been a running prototype of a product demonstrated. 2. The apparent failure of any license agreements to develop any productive products. 3. The cyclone engine is being presented as a complete (running/ engine/system); there is nothing shown but mock-ups of products. 4. I believe the Cyclone engine is still on the drawing board and should be presented as such. 5. In my judgement, the fact that a fuel burning steam engine is the right technology for these times is a "rational skepticism."
Mark, as an investor I would say the best answer to your question would be #4
