3M has introduced a sampling program for its HFE (hydrofluoroether) fluids that's available to engineers across a broad range of industries. The program gives companies the opportunity to experiment with and explore new applications for 3M HFEs as an alternative to chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS) in manufacturing and industrial processes. Primarily known for their use in precision cleaning of high-value, complex parts used in the electronics, computer, aerospace, medical equipment, and automotive industries, 3M HFEs also serve as: a carrier for specialty lubricant deposition on computer hard-disk drives; a component in spray contact cleaners used in electrical maintenance and repairs; an extraction medium to isolate oils or fragrances; a formulating agent combined with more active chemicals to neutralize their flammability or aggressiveness; a fluid for recirculating heat transfer; and an alternative to organic solvents for cleaning metallic and non-metallic chamber surfaces in dry-etch semiconductor wafer equipment. "Currently, there is no other product available in the marketplace with the desirable balance of performance, workplace safety, and environmental properties of 3M HFEs," claims Kathryn Williams, marketing operations manager, 3M Specialty Fluids.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
