I like this following sentence from ebmods web site:
"Only a select few actually do R&D on engines before releasing them. Jim Hottinger, Steve O'Donnell , JP Racing , Andy Brown , Dennis Ritchie , Rody Roem, Rich Reid , and myself are the only ones I can actually say have some sort of testing routine in place."

I didn't know that only 8 guys in whole world are doing some sort of real testing. No Andrea Rossi, no Michael Salven, no Massimo Fantini, no Alberto Picco, no 100s other guys-nobody!!!!
