Americans guzzle 65 billion gallons of fuel a year and lately we have been paying a pretty penny at the pump. NewsChannel 4 has done reports in the past on how to get the most out of your gas. Now we introduce you to a new way to save on those gasoline dollars.

There is a man who fills up his tank once every two months. One tank of gas, literally, lasts him two months. He is freezing the price of gas by freezing something else.

People complain about the price of gas and we are all spending dearly to stay on the road these days. The money we spend on gas seems to burn up faster than the fuel...........

David Hutchison says, “You should expect a “Cryo'd” engine to last anywhere from 600,000 to 1 million miles without wearing out.”

Wow. Amazing information - thanks.

This information should have been a major press release but it won't happen. This will probably be the only coverage the guy will recieve and the last we ever see or hear of it.

He should watch is back. He could wind up with one of those 'special neck-ties.'

There's got to be more to it than freezing the engine in liquid nitrogen--not that easy to do in ones garage for starters.

Too bad the oil and car moguls don't want fuel efficiency technology to take hold, but still, new good ideas just keep bubbling up.

From the article;

David Hutchison is a Cryogenics expert. He built this Cryo-Process himself. He runs a business out of his garage where he cryogenically tempers all kinds of metals. He submerges them in a frozen tank of nitrogen vapor that is 300 degrees below zero.

David says, “During that time, at minus 300 degrees, the molecules slow down. Then they reorganize themselves. That's when the actual chemical change happens.”

Hutchison cryogenically tempers machine parts, tools, golf clubs and even razors. He says it makes them last three to five times longer.

A few years ago he began an experiment on his hybrid Honda, freezing the engine components. The results were a fuel-efficiency dream.

Let me be the first to call BS on this one.

I have a bit of experience with cryogenic relaxation in rifle barrels. Whenever you machine a part out of metal, you create interior stresses. When the temperature changes, especially unevenly, the relationship between the interior stresses changes, and they can pull the part into a slightly different shape. In rifle barrels, this tends to cause shot stringing: as the barrel heats up, it bends (or unbends) almost imperceptibly in one direction or another--not really enough to measure, but enough to throw a bullet an inch or so off at 100 yards. Cryogenic relaxation eliminates those stresses, so that when the barrel gets hot it just expands; it doesn't bend.

I can imagine that cryogenic relaxation might improve things a little for an auto engine, but more than doubling the gas mileage is beyond anything I can imagine. The sort of rifles for which cryogenic relaxation is effective must shoot well both cold and hot (big-bore hunting rifles rarely fire more than one or two shots a day, so hot operation isn't as important to them); an auto engine consumes almost all of its fuel while it's hot. However distorted the parts are by the heat, they're going to wear themselves quickly to mate; that's how engines are designed. Once they're mated, the effect of cryogenic relaxation is gone. They won't mate quite as well when they're cold, but they don't stay cold very long: that's what cooling-system thermostats are for.

Completely aside from oil-company conspiracy nonsense, I say this story is full of it.

If it is true, an industry with a history like this is unlikely to allow him to profit from his idea.

I am a car mechanic and now autobody man. I remember when i was in germany and working on high end 12cylinder engines, before we were putting them together we sand them out for cryo treating (individual engine parts). The reputation was the highest in Europe from the shop for customizing engines. BUT it is not so simple as said in this article. All the parts have to be individual, welded is ok, bolted no way. No gaskets, seals on them. After the parts where going to the cruo machine (i am talking about the one that I saw) the machine would cryo the parts from their originally temp VERY slowly down to -310 a process that took the other company over a day. All computer regulated nothing like diping them nacked in cryo. Might diping be ok just for rasors or other small everyday things but nothing that has to be exposed in high end products like an engine or transmission that produce lot of friction.

Thanks for the shaving link - I got some cryo-blades for Mrs.L and me.

I'll have to defer to your knowledge and experience in this matter.

Thanks for the information.

To my knowledge, "soaking" auto parts in liquid nitrogen, especially crankshafts, is called "nitriding." (or, it used to be, circa 1960).

The process causes the crystalline structure of the part to change and make it more "dense," at least on the surface.

Sort-of an explanation here.
