Well, it's not a flying car, but at least we get liquid-nitrogen ice cream.

"A drop of liquid nitrogen creates a boiling sensation on a human hand because the human body is so hot to the chemical element. "

It's called frostbite. Sheesh.

(And this is nothing new-- Behold the smooth, sweet powers of liquid N.)

He wants a patent? Phui! We at XCOR have been making N2 ice cream all summer long. I have photos. When you don't have air conditioning, and you have a bunch of extra liquid nitrogen, instant ice cream becomes a company benefit. :-)
But a patent? Get real! Chemists and physicists have been doing this for years.

It's a start. I tried to get Toscanini's Ice Cream near MIT to make Liquid Helium Ripple, but they weren't interested.

Jay Leno's "Mad Scientist" did this for him a week or two ago. Just like in the Popular Science article linked above, they mixed the ingredients and then stirred in the Liquid Nitrogen. Just like in the article, it hardened within 30 seconds, and was rich and creamy because of the quick-freeze process.

This restaurant may have a rather difficult time getting the patent. Or, if he gets one in Italy, I doubt he'll get one in the US.

Something I still want to try out, though. :-)

Is this good enough, or do you want wingless like Jetsons had?

What's next? Benzene in alcoholic beverages?

In fairness to the inventors, reading the article carefully I get the impression that they have a _scoop_ cooled by LN2, which rapidly solidifies the ice cream mix. The gadget may be patentablewhere the simple idea of LN2 cooling is not.

That said, it doesn't seem very useful- pouring and stirring works mighty well, and is cheap & reliable. I also suspect that scraping the ice cream off the scoop could be difficult...

How about www.moller.com?

Think he will pull off the flying car?
