Extend the definition
The definition does not really sound right currently. Is there anthing better?
- An energy transformer is a device used to convert or, in other words, to transform energy from one form to another.
"For example, an internal combustion engine converts the potential chemical energy in gasoline and oxygen into thermal energy which, by causing pressure and performing work on the pistons, is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy)."
