A new NASA EPSCoR grant will help South Dakota Mines researchers explore the next generation of lithium sulfur batteries. Those batteries could be powered by the waste produced from processing plants.

The research was a team effort that spanned disciplines at South Dakota Mines. A few of the experts who worked on this project joined In the Moment to explain their work and unexpected discovery.

Rajesh Shende, Ph.D., is a professor of chemical and biological engineering. He specializes in finding uses for agricultural byproducts.

And Edward Duke, Ph.D., is a professor of geology and geological engineering and the director of the South Dakota Space Grant Consortium and the South Dakota NASA EPSCoR Program.

Video: How American Farmers Harvest 1.15 Billion Pounds of Sunflowers

Across the open plains of North Dakota and South Dakota, sunflower fields turn the American landscape into a sea of gold. In this farming documentary, we go inside modern sunflower farming to see how farmers plant, grow, harvest, clean, dry, process, and transform sunflower seeds into valuable products used every day.

In 2024, American farmers harvested about 1.15 billion pounds of sunflowers. This video follows the full journey from warm spring planting to combine harvesting, seed cleaning, storage, oil extraction, refining, roasting, packaging, and animal feed production.

You will see how sunflower seeds are processed into cooking oil, roasted snacks, bakery ingredients, birdseed, livestock feed, and useful byproducts. From golden fields to modern processing plants, this is the story of how a beautiful flower becomes one of America’s important oilseed crops.

Watch until the end to discover how sunflower farming connects farmers, machines, factories, food production, and sustainable agriculture.
