Real ‘freeze-ray gun’ inspired by Batman could soon help U.S. military

CHARLOTTESVILLE, Va. — Impressed by the fictional freeze-ray gun of Mr. Freeze from “Batman,” a College of Virginia professor could also be getting ready to turning science fiction into actuality. Patrick Hopkins, from the Division of Mechanical and Aerospace Engineering, believes he has stumbled upon a way to create a real-life freezing beam.

In contrast to the villainous intentions of Mr. Freeze, Hopkins’ intentions are solely for cooling the overheated electronics inside spacecraft and high-altitude jets.

“That’s the first drawback proper now,” says Hopkins in a university release. “Numerous electronics on board warmth up, however they haven’t any option to quiet down.”

This poses a big subject, particularly for the U.S. Air Force and Space Force, whose craft function in house or excessive altitudes, the place pure cooling mechanisms like dense air or water are unavailable.

Recognizing the potential, the U.S. Air Pressure granted the professor’s ExSiTE Lab $750,000 to advance the know-how. Following this analysis, Hopkins’ UVA spinout firm, Laser Thermal, will tackle the duty of crafting a prototype system.

How does it work?

Hopkins’ discovery delves into the fourth state of matter: plasma. Opposite to its fiery nature, plasma has a novel property — it will probably cool surfaces earlier than heating them. Of their lab checks, the group discovered that once they used a plasma jet on a gold-plated floor, the realm initially cooled down earlier than getting scorching. This baffling statement appeared to go towards recognized scientific legal guidelines.

What’s chargeable for this mysterious cooling impact? The evaporation of water molecules, much like the chilling sensation one feels when water evaporates off the pores and skin after a swim.

“Evaporation of water molecules on the physique requires power; it takes power from physique, and that’s why you are feeling chilly,” notes Hopkins. “On this case, the plasma rips off the absorbed species, power is launched, and that’s what cools.”

In mild of their findings, the group has begun refining the know-how, utilizing the Air Pressure grant to buy their very own gear. Researchers have been exploring the potential of various gases, metals, and floor coatings.

“We haven’t actually explored the usage of totally different gasses but, as we’re nonetheless working with helium,” says UVA doctoral candidate Daniel Hirt. “We have now experimented up to now with totally different metals, equivalent to gold and copper, and semiconductors, and every materials provides its personal playground for investigating how plasma interacts with their totally different properties.”

The examine is revealed within the journal ACS Nano.
