This matter could be compared to following the preparation of a food that is known to be delicious and not being able to taste it. What environmental problems? Why not get around them? A sensational call for a very poor conclusion.

Zero for the writing. Talk, talk, talk, and say nothing. My 8-year-old son can start and end a story more logically. Why is the engine amazing? What was the technological innovation? What sets it apart from other piston engines? Why did you have environmental problems?? Zerooooo
