How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Chevy Cruze CNG available from Crazy Diamond Performance

Anyone out there who can somehow find a second way to link Pink Floyd to natural gas vehicles gets a prize. Because so far, we have one Michigan-based company called Crazy Diamond Performance (Shine On You Crazy Diamond being a longtime Floyd fave) that's setting out to convert Chevrolet Cruze vehicles to run on compressed natural gas (CNG). All in the name of cheaper fuel and domestic security, of course. Crazy Diamond says it can offer a converted CNG-powered Chevy Cruze for a price as low as $26,000. That four-cylinder version has 130 horsepower and an 8.5-gasoline-gallon-equivalent capacity that provides a full-tank range of as many as 250 miles. Pony up another $2,000 or so and the peppier, turbocharged CNG Cruze can be yours. The company says it will provide a 100,000-mile powertrain warranty and is trying to get EPA certification for its conversions. The selling points are cheaper fuel (CNG is about half the cost of regular gasoline in some parts of the country) and homeland security (CNG reduces dependence on foreign oil). The only production passenger vehicle CNG in the US is the Honda Civic CNG, which sells in very limited numbers. Check out Crazy Diamond's flyer here.

UAW to vote on strike at Kentucky Corvette plant

The current wait time for a new Chevrolet Corvette Stingray is well, not short. With word of a strike at the Bowling Green, KY factory responsible for seventh-generation sports car, though, that wait time could end up growing substantially.
Now, a strike is still a ways off. UAW Local 2164, which represents the 800 workers responsible for screwing the Corvette together, is set to vote on authorizing a strike today, but even if the employees give the action a go, it's far from a sure thing. According to The Tennessean, both regional and national union officials would need to put their stamp of approval on strike action.
"The membership has to vote to strike, but it's just a step in the process," said Gary Casteel, the UAW's Region 8 director and one of the people that would need to authorize a strike action. Casteel told The Tennessean, "It's purely a local situation, though. They are having some issues with the local management."
