Iowa State University showcasing Ames National Laboratory at Iowa State Fair

As visitors at the Iowa State Fair play with water as a substitute for liquid metal and feel the cooling effects of magnetic refrigeration, the director of Ames National Laboratory also wants people to think about how their actions affect the future.

Iowa State University’s exhibit at the fair’s Varied Industries Building will highlight the work of the national lab, which is celebrating its 75th anniversary this year.

Lab director Adam Schwartz said, “We want all Iowans, all the U.S. and really all the world to be attentive to their resource usage.”

Schwartz said it’s easy to imagine the world with a billion more people in it in 10, 20 or 30 years — all of whom will need clean air, clean water and food, while resources on Earth are getting harder to find and more expensive and environmentally damaging to extract.
