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.

Recharge Wrap-up: NEDC's NOx problems, autonomous Chevy Volts

The International Council on Clean Transportation (ICCT) found a significant difference in NOx emissions in Euro 6 diesel cars in NEDC and WLTC testing. While 88 percent of the cars tested met emissions standards for NEDC, NOx emissions averaged five times higher under WLTC, with only 27 percent of vehicles under the limit. WLTC is considered to be a more realistic driving cycle, using hot starts and factoring a higher top speed as well as harder and more frequent accelerations than the NEDC.

Employees will be able to use a carsharing app to reserve a car, which will then drive itself to the set destination. The project will allow GM to collect important data and experience to help the company more quickly develop autonomous driving technology.

The lithium-ion batteries used to power the EV were recycled from other Renault EVs. With the electric Trafic, Carwatt – a company that converts vehicles to use electric power – aims to demonstrate the "circular economy" of batteries, which can provide more value through a longer lifecycle. Read more in the press release below. Carwatt presents a unique automotive application for second-life batteries from electric vehicles. On the sidelines of the COP21 summit, in the Solutions Gallery running from 2 to 9 December 2015 in Le Bourget near Paris, Carwatt and its partners —Renault, Paris City Council, BPI France, the Ales Ecole des Mines Engineering School, and the Bobigny Business Campus — are showing a very special electric Renault Trafic. This prototype vehicle, the only one of kind in the world, is powered by second-life lithium-ion batteries recycled from Renault electric cars. Circular economy at work with electric vehicles When, over time, the batteries of a Renault electric vehicle fall the performance threshold specified for their initial automotive power duty (around 75% of initial capacity), they can still provide valuable service in "second-life" applications before end-of-life disposal at a recycling centre. Experiments are already under way on power storage applications, for example.
