We took a sightseeing tour on a steamboat (with a big paddle wheel in the back) while visiting New Orleans. The ship carried over 1200 people. It had boiler fired by diesel generating steam to power reciprocating pistons. What surprised me is that it had "only" 2000 hp. That is like 2hp/person. If your car had that efficiency, you will only need 8hp motor for a typical four door sedan! But we "need" at least 240 hp otherwise we feel our car is under powered.
Why 80x difference in efficiency?
