The Diesel Technology Forum — a non-profit group that works to raise awareness about the environmental progress of diesel engines — has reported that ultra-low sulfur diesel (ULSD) fuel has become widely available at fueling stations nationwide. The development has calmed concerns over the availability and performance of the fuel for heavy-duty trucks designed specifically for ULSD.
More than 93 million gal of ULSD were refined in July 2007, up from 54 million barrels during July last year. ULSD now accounts for 75 percent of all distillate fuel production. The EPA estimates that 90 percent of all retail service stations that have diesel fuel are now carrying ULSD, exceeding the 80 percent minimum level. Over the last year, 838 million barrels of clean diesel have entered the U.S. distribution system.
The Industrial Internet of Things may be going off the deep end in connecting everything on the plant floor. Some machines, bearings, or conveyors simply don’t need to be monitored -- even if they can be.
Wind turbines already are imposing structures that stretch high into the sky, but an engineering graduate student at the University of Notre Dame wants to make them even taller to reduce energy costs and improve efficiency.
