Who invented diesel powered ships and what is that?

Question

answers plz thanks

Answer 1

the diesel engine was invented by a guy named Rudolph Diesel;look him up on the Web

once the technology was developed ( pretty much during and then right after WW2) diesel engines replaced steam boilers that ran steam engines; diesel was WAY simpler and cheaper and more efficient; you didn't have to boil water at many hundreds of ponds pressure and use that steam to drive pistons  and then cool it down and make it steam again........just an engine  like the ones in a truck or car...just WAY bigger......

Answer 2

Early in the twentieth century. If you search the web you get more than a million hits on diesel powered ships. Hey, lots to be learned on the history channel too.
