Frozen man's freezing gun is expected to become a reality, scientists show "frozen ray" technology

CTOnews.com, August 3 (Xinhua)-- in the DC universe, Mr. Freeze has developed a frozen light gun that can reach absolute zero, and Professor Patrick Hopkins (Patrick Hopkins) from the University of Virginia is expected to make this idea a reality.

It's just that the professor developed a "frozen ray gun" not to be used as a weapon, but to cool electronic devices in spacecraft and high-altitude jets.

Professor Hopkins' ExSiTE Lab has received a $750000 grant from the U.S. Air Force and plans to work with Laser Thermal to build prototype equipment.

Professor Hopkins emitted a plasma jet made of helium in a laboratory environment and could see a purple glow.

The professor said that at present, due to the inertia of gold, choosing it as the target surface has been able to achieve cooling, and the next goal is to improve the freezing effect and reduce the etching effect of the beam on the target surface.
