In December 2011, Ghulam Sarwar claimed he had invented a car that ran only on water. At the time the invented car was claimed to use 60% water and 40% Diesel or fuel, but that the inventor was working to make it run on only water, probably by end of June 2012. It was further claimed the car "emits only oxygen rather than the usual carbon". [35]
The water fuel cell is a non-functional design for a "perpetual motion machine" created by Stanley Allen Meyer (August 24, 1940 – March 20, 1998). Meyer claimed that a car retrofitted with the device could use water as fuel instead of gasoline. Meyer's claims about his "Water Fuel Cell" and the car that it powered were found to be fraudulent ...

A water power engine includes prime movers driven by water and which may be classified under three categories: [1] Water pressure motors, having a piston and cylinder with inlet and outlet valves: their action is that analogous of a steam- or gas-engine with water as the working fluid – see water engine
The Amphicar's engine was mounted at the rear of the craft, driving the rear wheels through a 4-speed manual transmission. For use in the water, the same engine drove a pair of reversible propellers at the rear, with a second gear lever engaging forward or reverse drive. Once in the water, the main gear lever would normally be left in neutral.
Although the liquid nitrogen is colder than the ambient temperature, the liquid nitrogen engine is nevertheless an example of a heat engine.A heat engine runs by extracting thermal energy from the temperature difference between a hot and a cold reservoir; in the case of the liquid nitrogen engine, the "hot" reservoir is the air in the ambient ("room temperature") surroundings, which is used to ...

The engine temperature on modern cars is primarily controlled by a wax-pellet type of thermostat, a valve that opens once the engine has reached its optimum operating temperature. When the engine is cold, the thermostat is closed except for a small bypass flow so that the thermostat experiences changes to the coolant temperature as the engine ...
