It is pretty damn cool, i like these threads no bs just the facts .. i can't wait to see
what's next with the way we are advancing in this world..
is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly. This is most commonly seen when cooking; one sprinkles drops of water in a skillet to gauge its temperature—if the skillet's temperature is at or above the Leidenfrost point, the water skitters across the metal and takes longer to evaporate than it would in a skillet that is above boiling temperature, but below the temperature of the Leidenfrost point.
“We thought we could improve the transition” from the Leidenfrost regime to bubbling, says Vakarelski, “but we are not only lowering the transition, we are completely avoiding it”. “It was really dramatic,” says Neelesh Patankar, a theoretical mechanical engineer at Northwestern University in Evanston, Illinois, and a co-author of the paper. “As the temperature goes down, this vapour phase nicely settles down.”
The researchers think that this could help to reduce damage to surfaces, help prevent bubbling explosions and could eventually be useful as a way to “enhance heat transfer equipment, reduce drag on ships and lead to anti-frost technologies.”

This is nothing new. Microwave ovens are able to super heat water past boiling - depending on the type of container the water is in, the water ( at or over the boiling point) won't produce bubbles..
