Wave Energy Simulation Team Carries Home International Award

In order to harness the power of waves to generate electricity, engineers must be able to predict how large floating devices will perform in a dynamic environment—that is, in the water among waves. A team sponsored by the Energy Department, including members from NREL and Sandia National Laboratories, addressed that challenge and won a recent international competition.

From Flour to Grits, a Water-Powered Mill Keeps on Grinding

A mill owned and operated for six generations by the Weisenberger family has been grinding grains in the heart of Kentucky since the Civil War. In 1862, August Weisenberger emigrated from Baden, Germany, to start milling grains in Midway, Kentucky. He purchased the existing three-story stone mill on the banks of South Elkhorn Creek in 1865—the perfect location to harness water power to operate the mill.
