It took energy to create the liquid nitrogen.
How much energy?
More than he saved in gas?

 

I use cryo'd cables in my stereo system and it makes one heck of an improvement in the sound. Maybe we could get honda to do the same in their car audio.

Sounds to me like the cryo process got to this guy's brain cells... and some of yours. May I be the first to proclaim hogwash!?

 

The cryo process is significant for certain things, it can remove microscopic physical imperfections in the metal's internal structure. Any undergraduate material science class talks about cryo, in addition to tempering and hardening of metals, they are all different thermal treatment processes.

That being said, most of the cryo sellers are full of BS, it can't possibly give as large of a FE increase as is being claimed, it doesn't make any changes significant enough to change audio cables (take my word... I am an electrical engineer, an audio system designer, and an audio enthusiast), and it is not a magic bullet. Some people even drink "cryoed water" because they think it is better for them then water that hasn't been dunked in liquid nitrogen.

That being said, it removes sites that could be fracture initiation points, improves wear properties, can modify hardness (up or down depending on the material properties), and can change spring characteristics of the object processed. It is especially significant for tooling like pressed and dies, and for competition firearms.

So yes, a lot of hogwash but not complete hogwash.

I have put a pint of Slick 50 along with the oil in the past. It's supposed to coat the engine with Telfon to reduce friction and improve durability. I did not notice a significant difference....

 

Take a look at this pivotal quote from the story:

A hybrid Honda typically gets really great gas mileage anyway, around 50 miles to the gallon, but David Hutchison's cryogenically tempered engine has been known to get close to 120 miles a gallon.

Well, my HCH without cryo processing "has been known to get 120 mpg" too, every time I coast it jumps right up to 120. Who needs cryo BS for that? This kind of reporting is a bunch of hooey.

 

as the original poster, i don't plan to try it, i just found it interesting, especially since he was using an HCH......

 

Looks more like an Insight to me:
