Notice they didn't mention Mr. Graves.(the great engineer from Texas)....or the fact that all the described "split-cycle technology"companies are decades behind in captive pulse style two-stroke engine development when compared to even the original hydrogen fueled engines that were demonstrated in the late 90's...They were all obsolete before they even got started......this must be the sandbox crowd of the engine world....the real players don't play around
