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.

Hot air balloons caught in high winds drag fullsize SUV

A sudden storm front whipped up enough wind to send some hot air balloons flying into the air in Wisconsin over the weekend. One ballon proved so energetic that it was able to drag a fullsize SUV across a field and into a stand of tents. The freak accident occurred at Balloonfest in Waterford, Wisconsin. Spectators were horrified as balloons dragged handlers to the ground and launched with terrified pilots clinging to their baskets. Organizers had started packing up the colorful balloons due to ominous storm clouds when the wind kicked up. "Happened just like that; it was crazy," Nathan Fricke, crew member, told Fox 6. Winds were clocked at 40 to 50 miles per hour. A balloon caught in the wind dragged a large SUV (we think a Suburban or Yukon XL) hundreds of feet and into a cluster of tents on the edge of the staging area where balloons were on display for festival goers. Considering that the SUV surely weighs well over 5,000 pounds, it's lucky that no one was injured in the incident. News Source: Fox6Now Weird Car News Chevrolet GM GMC SUV

GM raises 2023 guidance on strong sales, higher profits

General Motors beat first-quarter profit estimates and raised its full-year earnings and cash-flow guidance after vehicle demand at the start of the year surpassed expectations. Its shares rose in premarket trading. GM made $2.21 a share in adjusted profit in the first quarter, compared to a consensus forecast of $1.72 a share. Revenue rose 11% to $39.99 billion, it said Tuesday, which was more than the $39.24 billion analysts expected. The stronger results stem from rising sales in the US, even in the face of higher interest rates and inflation. GM executives said demand was strong enough to revise 2023 guidance upward, boosting profit estimates for the year by $500 million to between $11 billion and $13 billion. “We did it with strong production and inventory discipline and consistent pricing,” GM Chief Financial Officer Paul Jacobson said on a call with journalists. “All in all, weÂ’re feeling confident about 2023.” The Detroit automaker raised per-share full-year guidance to between $6.35 and $7.35, up from $6 to $7 a share, and said free cash flow would also increase by $500 million to a range of $5.5 billion to $7.5 billion.  GMÂ’s shares pared a gain of as much as 4.4% before the start of regular trading Tuesday, rising 3.5% to $35.50 as of 6:55 a.m. in New York. The stock was up 1.9% for the year as of the close on Monday.  North American Strength The automakerÂ’s sales were particularly strong in North America, where first-quarter earnings rose before interest and taxes rose to $3.6 billion. Vehicle sales rose 18% to 707,000 in the region. Jacobson said the company originally expected to sell 15 million vehicles in the US this year, slightly less than the 15.5 million annualized rate automakers foresaw in the first quarter. North American demand was enough to offset a weak performance in China, GMÂ’s second-largest market. The automaker continues to struggle in the country, where its vehicle sales fell 25% to 462,000 vehicles in the quarter. Profits from its joint ventures in the market slumped 65% to $83 million.  The market has struggled overall in the wake of Covid-19 restrictions and foreign automakers have had to overcome a growing preference for Chinese brands by competing on price, squeezing profit margins. The situation in China probably wonÂ’t significantly improve until the second half of the year, according to Jacobson. GM remains on target to sell 150,000 electric vehicles this year, the CFO said.
