Although the blackouts and brownouts that plague California haven't reached Midwest states like Ohio yet, that hasn't stopped engineers and scientists in the buckeye state from finding better ways to produce electric power. The plan is to use a Norton, OH limestone mine as a storage facility for compressed air released from a nearby power plant. The idea is to build air pressure into the mine during evenings, weekends, and other off-peak hours, according to the Department of Energy's Steve Bauer. His job involves characterizing the limestone rock's mechanics and airflow properties, because without a clear understanding of the behavior of the rock in a pressurized state and the behavior of fluid in the rock, funding agencies are reluctant to back the plan. "The mine acts as a vessel that contains the air at pressures from 800 to 1,600 psi," says Bauer. He explains that in the rock's pores, the air will move from high pressure areas near mine surfaces to lower pressure areas away from mine surfaces when the air pressure is greater than the rock pore pressure. "The movement is very slow because of the low permeability of the rock and the fact that there is brine in the rock-pore space," says Bauer. During peak electrical usage times, the stored compressed air is bled off through turbines for creating additional electric power. Permits are currently being sought through the state's regulatory agency.
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
