Okay, my patience wore out at the 5:00 mark. Does he have a prototype engine installed in a car? Or does he just keeps yapping about his mighty engine?
The idea is fantastic. Whether it's practical is another question entirely.
Another thing. As heavy and bulky and hot as engines are, they serve another purpose other than to provide power for a vehicle's locomotion. The vast majority of vehicles have the engines located in the front. In a frontal collision, engines help absorb the force of impact.
Now, if auto manufacturers start building vehicles with these pipsqueak engines, what will serve as a substitute barrier between the vehicle's cabin and an uncoming car? And before some says, "Well, you're going to get hurt or killed anyway", please remember that vehicles are designed to be survivable in some types of crashes.
Sorry, about getting off-topic some, but it's curiosity, you know?
