Steam engines produce smoke from the coal or wood they burn to produce heat to boil water tocreate pressure to drive pistons to move drive wheels. The "smoke" most people see is actually steam vapor from stack released during operation.
Yes, if the the engine is a steam engine or a diesel engine. The diesel engine smoke should be almost invisible when the engine is in good condition. Electric locomotives are not typically called "engines", but these do not produce smoke.
It's not smoke, it's steam. When the water in the air passes through the airplane's engines, it warms up and becomes steam.
If it is white smoke you probably have something in the electrical system burning. If it is actually steam, your vehicle is overheating. Either way I wouldn't operate the vehicle until I knew what it was and had it corrected.
Steam engines presently produce more power than all other types of engines combined. Most steam engines take the form of the steam turbine engine. The steam turbine is responsible for generating about 86% of the electric power used on this planet. Reciprocating steam engines are still in use for limited applications, but are generally considered obsolete. Steam engines, either the piston or turbine type were used on most big ships until recently, and there are still a few steam locomotives about.
no, hot showers may produce Steam, not smoke
