By harnessing these natural forces, we can generate electricity, heat, and fuel without depleting Earth's resources. Energy ...

A very inefficient device will waste most of its input energy. The efficiency of a device is the proportion of the energy supplied that is transferred in useful ways. The efficiency can be ...

KIMS and KAIST have developed a catalyst synthesis process and precision control technology to optimize carbon dioxide ...

A new study has revealed key factors limiting the efficiency of photoelectrochemical water splitting using a titanium dioxide photoanode for clean hydrogen production. Researchers combined ...

In an ideal case, this process would be perfectly reversible and the Carnot engine would have maximum efficiency. In reality, real heat engines are not reversible and lose energy in the form of heat.
