Scientists Now Invented A Device That Can Turn Heat Into Fuel Source

Written By : Saicharan Palakurthi

Recent advancements in the field of gadgets and technology are quite impressive. Various reverse mechanisms are in hands with so many hard tasks made easy all the way.

The recent invention which is about to be wrapped up soon enough is as interesting as anything. A physicist is developing a device that could turn the heat generated by electronics into a usable fuel source. And, according to the research results published in the Journal of Physical Chemistry Letters, the multicomponent, multilayered composite material device is called a ‘Van Der Waals Schottky diode’.

This device is capable of converting heat into electricity up to three times more efficiently than silicon, a semi-conductor material widely used in the electronics industry since its advent.

Yi Gu, a physicist from Washington State University has said, “The ability of our diode to convert heat into electricity is very large compared to other bulk materials currently used in electronics, in the future, one layer could be attached to something hot like a car exhaust or a computer motor and another to a surface at room temperature.”

He added, “The diode would then use the heat differential between the two surfaces to create an electric current that could be stored in a battery and used when needed.”

With the complete eccentric capabilities in the world of electronics, Schottky diodes are used to guide electricity in a specific direction. They are made by attaching a conductor metal like aluminum to a semiconductor material like silicon.

Matthew McCluskey, the study’s co-author said, “When you attach a metal to a semiconductor material like silicon to form a Schottky diode, there are always some defects that form at the interface.”

“These imperfections trap electrons, impeding the flow of electricity. Gu’s diode is unique in that as its surface does not appear to have any of these defects,” McCluskey added.

This device is more efficient as it lowers resistance to the flow of electricity.
