Scientists discover nano engine
Q. Scientists have developed the world’s smallest engine. What it is powered by?- Published on 05 May 16
Scientists have developed the world's tiniest engine -just a few billionths of a metre in size -which is powered by light
- This may help develop nano-machines that can navigate in water, sense the environment around them, or even enter living cells to fight disease.
- When the 'nano-engine' is heated to a certain temperature, it stores large amounts of elastic energy in a fraction of a second. Light can be used to power the piston of the nano engine.
