Why do human electricity generation so focused on efficently boiling water and turning a turbine with it. do we have other ways of generating electricity every power plant i know (coal gas nuclear) does the turbine method ? And why is boiling water and turning a turbine with it so great ?
In: Physics
Lots of exceptions, as other have pointed out.
We get power by converting some other form of potential energy into electrical potential (voltage).
Water expands when it transitions to steam, creating a difference in pressure (potential energy) that can be used to convert mechanical action into electrical power.
Hydroelectric relies on potential energy from gravity rather than thermal expansion.
Solar cells generate current directly from EM radiation, so they act more like a receiver of transmitted energy than a generator or converter of chemical or gravitational energy to electrical power.
