Nanoscale generators can turn ambient mechanical energy–vibrations, fluid flow, and even biological movement–into a power source. Now researchers have combined a nanogenerator with a solar cell to ...

An unconventional engine design is attracting attention as a potential alternative to hydrogen fuel cells or conventional engines in some hybrid vehicles. Called the free-piston engine, it could be ...

The road to reduced carbon emissions and cleaner energy solutions was never likely to be smooth. This is true globally, but particularly in the US today, where the new administration’s views on ...
