Doesn't really matter what kind of energy source you use, water isn't an efficient media to transmit electricity through.
Current Electricity
Think of a 9-volt battery and you have your answer: electricity.
distilled water
Hydropower plants use flowing water from rivers, dams, or waterfalls to generate electricity through turbines. This water flow drives the turbines to produce mechanical energy, which is then converted into electrical energy.
Static.
"closed"
Salt water
things that don't allow electricity or heat to pass through them. Example: Bakelite(a kind of plastic),dry air pure water,etc
Car batteries are filled with sulfuric acid, not water. The battery fluids get "topped up" with distilled water if they get low.
Hydroelectric power.
The energy from water falling over a dam is primarily potential energy that is converted into kinetic energy as it flows through turbines to generate electricity.
Hydroelectric plants capture the energy of the flowing water and convert it into electricity.
