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.

2016 Green Truck of the Year, Commercial Green Car of the Year finalists

Not only are commercial-grade haulers getting more green love lately, they're getting more different kinds of green love. The 2016 Green Truck of the Year, the second time the award has been handed out, is being decided by judges from Green Car Journal and the San Antonio Auto & Truck Show. This year the award is joined by the new 2016 Commercial Green Car of the Year, which crowns one of the little vans increasingly used by small business as cargo and delivery vehicles. The Green Truck of the Year finalists are the Chevrolet Colorado Duramax (pictured), Ford F-150, GMC Canyon Duramax, Nissan Titan XD, and Toyota Tacoma. The first three of those were on last year's list, but since they are completely new or upgraded for 2016 - Ford with its all-aluminum body, the General Motors twins with the new diesel Duramax engine - they qualify for entry again. The Ram 1500 EcoDiesel won last year. The Commercial Green Car finalists are the Chevrolet City Express, Ford Transit Connect, Mercedes-Benz Metris, Nissan NV200, and Ram ProMaster City. You can read more details in the presser below, and the awards will be announced in San Antonio sometime during the show from November 19-22. San Antonio Auto & Truck Show Announces 2016 Green Truck of the Year and Commercial Green Car of the Year Finalists SAN ANTONIO, Oct. 22, 2015 /PRNewswire/ -- Green Car Journal and the San Antonio Auto & Truck Show have announced finalists for the 2016 Green Truck of the Year™ and 2016 Commercial Green Car of the Year™ awards.

Vying for the all-new 2016 Commercial Green Car of the Year™ award are the Chevrolet City Express, Ford Transit Connect, Mercedes-Benz Metris, Nissan NV200, and Ram ProMaster City. "Over the past few decades, new car models have benefitted from design and technology improvements that have brought higher fuel efficiency and greater levels of environmental compatibility," said Green Car Journal and CarsOfChange.com Editor and Publisher Ron Cogan. "With models like these ten deserving finalists, we're witnessing the pickup and light commercial vehicle field enjoying the same attention." The new Commercial Green Car of the Year™ award is part of an expanded awards program presented at this year's 2015 San Antonio Auto & Truck Show.
