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.

New Bright creating exclusive 1:8 scale radio-controlled C7 Corvette

If you want a new 2014 Chevrolet Corvette but can't quite save up enough pennies for the monthly payment, we have good news for you. Toymaker New Bright has pulled the covers off of its 1:8 scale remote-controlled version of the American sports car. Complete with a very detailed interior and LED headlights, this large-scale R/C is as close as most of us will ever come to having one of the menacing Chevrolet models to call our very own. New Bright still hasn't released pricing or availability, but word has it the coupe should hit the market soon.
Right now, it appears as if the C7 will hit shelves in Torch Red, though we don't know if other colors are planned as well. The good news is that New Bright isn't exactly turning its back on the old C6 - representatives say the company will continue to make its popular C6R racecar for those who prefer round taillights.

Jay Leno drives Joe Rogan's '65 Chevy Corvette restomod

Restomod classics often look great rolling down the road, but they can be an absolute mess underneath. That's the problem comedian Joe Rogan discovered after purchasing his 1965 Corvette convertible that was already extensively modified. Once work began to improve it further, some serious issues were discovered. Now, Rogan's rejuvenated 'Vette has received a thorough update on the latest, extra-long edition of Jay Leno's Garage. Rogan's additional upgrades include a new interior and adding nacelles behind the seats. Power is up thanks to a supercharger for the LS1 V8. Now only do you get to hear the engine roar, but Leno and Rogan also take the convertible for a long ride in the Los Angeles hills. They reminisce about liking cars as kids, the current state of General Motors, and Rogan's work with the UFC. Leno also shares a funny story about a confusing discussion with Marlon Brando. With the beautiful 'Vette and the great conversation, there's a lot here to like. Related Video:
