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.

GM’s move to Woodward is the right one — for the company and for Detroit

Back in 2018, Chevy invited me to attend the Detroit Auto Show on the company dime to get an early preview of the then-newly redesigned Silverado. The trip involved a stay at the Renaissance Center — just a quick People Mover ride from the show. IÂ’d been visiting Detroit in January for nearly a decade, and not once had I set foot inside General MotorsÂ’ glass-sided headquarters. I was intrigued, to say the least. Thinking back on my time in the buildings that GM will leave behind when it departs for the new Hudson's site on Woodward Avenue, two things struck me. For one, its hotel rooms are cold in January. Sure, itÂ’s glass towers designed in the 1960s and '70s; I calibrated my expectations accordingly. But when I could only barely see out of the place for all the ice forming on the inside of the glass, it drove home just how flawed this iconic structure is.  My second and more pertinent observation was that the RenCen doesnÂ’t really feel like itÂ’s in a city at all, much less one as populous as Detroit. The complex is effectively severed from its surroundings by swirling ribbons of both river and asphalt. To the west sits the Windsor tunnel entrance; to the east, parking lots for nearly as far as the eye can see. To its north is the massive Jefferson Avenue and to its south, the Detroit River. You get the sense that if Henry Ford II and his team of investors had gotten their way, the whole thing would have been built offshore with the swirling channel doubling as a moat. This isnÂ’t a building the draws the city in; itÂ’s one designed to keep it out. Frost on the inside of the RenCen hotel glass. Contrasted with the new Hudson's project GM intends to move into, a mixed-use anchor with residential, office, retail and entertainment offerings smack-dab in Detroit's most vibrant district, the RenCen is a symbol of an era when each office in DetroitÂ’s downtown was an island in a rising sea of dilapidation. Back then, those who fortified against the rapid erosion of DetroitÂ’s urban bedrock stood the best chance of surviving. This was the era that brought us ugly skyways and eventually the People Mover — anything to help suburban commuters keep their metaphorical feet dry. The RenCen offered — and still offers — virtually any necessity and plenty of nice-to-haves, all accessible without ever venturing outside, especially in the winter, but those enticements are geared to those who trek in from suburbia to toil in its hallways.

7 major automakers to build open EV charging network

A new joint venture established by BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz and Stellantis will build a new North American electric vehicle charging network on a scale designed to compete with Tesla's industry-benchmark Supercharger network. The 30,000-plus planned new chargers will accommodate both Tesla's almost-standard North American Charging System (NACS) and existing automakers' Combined Charging System (CCS) options, effectively guaranteeing compatibility with the vast majority of current and upcoming electric models — whether they're from one of the involved automakers or not.  "With the generational investments in public charging being implemented on the Federal and State level, the joint venture will leverage public and private funds to accelerate the installation of high-powered charging for customers. The new charging stations will be accessible to all battery-powered electric vehicles from any automaker using Combined Charging System (CCS) or North American Charging Standard (NACS) and are expected to meet or exceed the spirit and requirements of the U.S. National Electric Vehicle Infrastructure (NEVI) program." Critically, the automakers involved will have a say in how the charging tech is implemented, guaranteeing that the hardware will play nicely with each automaker's in-house charging systems. Hyundai and Kia, for example, were hesitant to jump on board the Tesla NACS bandwagon earlier this year over concerns that the Supercharger network is insufficient for powering the two automakers' 800-volt charging systems; similar tech is used by Volkswagen and Porsche.  In addition to providing much-needed capacity and high-output charging for America's growing fleet of electric cars and trucks, the new network will integrate seamlessly with each automaker's in-app and in-vehicle features, rather than forcing customers to use third-party tools and payment systems, as is the case with some existing public charging infrastructure.  "The functions and services of the network will allow for seamless integration with participating automakersÂ’ in-vehicle and in-app experiences, including reservations, intelligent route planning and navigation, payment applications, transparent energy management and more. In addition, the network will leverage Plug & Charge technology to further enhance the customer experience," the announcement said.
