I thought of something two days ago and it made me laugh so hard I woke my mom up and she yelled at me to go back to sleep. I'll tell you guys later what I though about, but first this question:
Would you trade efficency for both noise and exhaust pollution?
If there was an engine that could somehow reduce the amount of noise it produces as well as the pollutants in it's exhaust at the same time yet be either as efficient as current engines or less; honestly for the sake of argument, how would you feel about that?
In other words would it matter to you?
