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.

EV tax credits: Here's every electric car or plug-in hybrid that qualifies

Starting on April 18, the Internal Revenue Service released new guidance for U.S. buyers shopping for a new electric or plug-in hybrid vehicle. On April 18th, the IRS showed only six fully electric vehicles on the qualified list, but a day later Volkswagen confirmed its U.S.-built ID.4 also qualifies. That means right now, seven fully electric vehicles qualify for the full $7,500 EV tax credit, with three more from Chevrolet coming for the 2024 model year (we would expect these 2024 models to roll out slowly and be difficult to find for at least the first few months they are on the market). In addition to those seven fully electric cars, two plug-in hybrids also qualify for the full $7,500 credit. To qualify, a vehicle must be assembled in North America and must meet a strict set of guidelines that cover where battery materials were sourced. If any battery materials come from certain countries (importantly including China), the vehicle's tax credit is automatically cut in half. Further, according to the IRS, the vehicle's manufacturer suggested retail price (MSRP) can't exceed $80,000 for vans, sport utility vehicles and pickup trucks or $55,000 for any other type of vehicle (basically meaning sedans). Electric vehicles that qualify for the full $7,500 EV tax credit: Cadillac Lyriq (2023-2024) Chevrolet Blazer EV (2024) Chevrolet Bolt EV (2023-2024) Chevrolet Bolt EUV (2023-2024) Chevrolet Equinox (2024) Chevrolet Silverado (2024) Ford F-150 Lightning — all models (2022-2023) Tesla Model 3 Performance (2022-2023) Tesla Model Y — all models (2022-2023) Volkswagen ID.4 — U.S.-built models (2022-2023) Plug-in hybrid cars that qualify for the full $7,500 EV tax credit: Chrysler Pacifica PHEV (2022-2023) Lincoln Aviator Grand Touring (2022-2023) A smaller credit is offered on fully electric cars and plug-in hybrids that are assembled in North America but have batteries with materials sourced from unqualified countries (mostly China).
