Their claim defies the second law of thermodynamics. (ref. "How do you feel about their claim that the exhaust is at room temperature due to common inlet/exaust passage with charge dilution etc?")

This company is a VERY dangerous investment. I would urge all potential investors in this company to do their due diligence and not rely upon information solely derived from the company's marketing office.

I work for NASA. NASA never has and never will give product endorsements. Further, any use of the NASA name or logo is illegal without prior authorization. AET may have given a product "demonstration" to Lewis Research Center. NASA centers are often asked by industry vendors for permission to give demos. This never implies endorsement. It is unlikely that any NASA engine dynamometer was used for the demo, but I will investigate this with my contacts at Lewis. Any test or demonstration that used AET equipment and not independent test equipment is useless because it is easily rigged to give whatever results the demonstrator wishes. It could easily be fraudulent, not only at the Lewis site but at any other site as well.

The company makes a claim about "leveraging" the output and improving the performance of the engine substantially by replacing the crankshaft with a new design which is the subject of their patent. At no time has the company claimed to patent an engine. Their patent will be on a new type of output shaft that collects the power from the combustion process. The losses from the crankshaft in a thermodynamic cycle are minimal. It is not possible that the efficiency of the engine could be improved significantly by a new "crankshaft".

This engine may be a "scroll engine" which forms combustion chambers through the meshing of two involute spirals. The total number of moving parts for such an engine is 3. The moving scroll, the "crankshaft" and a compliant bushing. It would require two spark plugs. If, indeed, the engine is a scroll engine, then the thermodynamic cycle would be a slightly modified otto-cycle. The sealing surfaces would rely upon a type of piston ring and no contact between "piston" and "cylinder" would take place. These types of engines have been previously patented but have not proven to be commercially viable.

I'm not long nor am I short on this stock. I wouldn't touch it with a ten foot pole.

With all due respect to you Greg. I've come across your posts before. You're not a hypster. You seem to be genuinely impressed with this company. As one SI investor to another: be careful with this one. It is likely an unintentional disaster.
