The physicists successfully built the smallest engine in the world

A group of physicists at Trinity Dublin University of Ireland has successfully built what they consider to be the smallest engine in the world.

The newly built ultra-small engine promises a new breakthrough in the future.

This motor is about the same size as a calcium ion, about 10 billion times smaller than a car engine.

One day, atomic engines can be used to lay the groundwork for future nanoscale technologies.

The active way of the newly shared engine is that the calcium ion will hold the charge, making it spin and then used to convert the heat from the laser beam into vibrations.

In return, these vibrations act like a " flywheel" - a mechanical device capable of storing rotating energy.

"Flywheels allow us to really measure the power output of atomic-scale motors , " said study co-author Mark Mitchison.
