Running a 500-hp air compressor can be costly. In one year, operations costs can exceed four times the initial price of the compressor. To combat that problem, Gardner Denver's Electra-Saver Two-Stage Rotary Screw Compressor employs the simplicity of a single-stage design in a two-stage package. It also uses a special power-saver system to introduce lubricant between stages, reducing oil introduction into the two compression stages and cooling inlet air temperature into the second stage by 50F. By reducing the impact of oil drag and heat, a more efficient compressor is created. Gardner Denver: Product Code 4186.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
