Powered By Humidity, Watch a Teeny Tiny Car Leverage Its Energy From Evaporation!

By: | June 18th, 2015

Scientists continue to do incredible things on a daily basis, whether it be on a large scale or a small scale.

Recently, a team at Columbia University used humidity as fuel in order to power a tiny, 0.1-kilogram vehicle.

Microscopic, moisture-sucking spores as an energy source could potentially lead to utilizing the free power of changes in humidity to run transistors.

A bacteria species called Bacillus subtilis, which has sports that swell or shrink as they react to the moisture in the air, was used in the study.

While humidity is typically annoying to deal with, the video below shows how neat it can be when it comes to leveraging it for energy.

The wheel turns and the miniature car moves as the yellow polymer strips covered in spores cycle through closed air and open air.
