A 150-ton magnet, developed in part by MIT engineers, is pulling the world closer to nuclear fusion as a potential source of energy. In nuclear fusion, light elements are fused together at enormous pressures to make heavier elements, a process that releases large amounts of energy. Powerful magnets provide the magnetic fields needed to initiate, sustain, and control the plasma, or electrically charged gas, in which fusion occurs. Over the last three years, "We've shown that we can design a magnet of this size and complexity and make it work," said Joseph V. Minervini, a senior research engineer at MIT's Plasma Science and Fusion Center (PSFC) and Department of Nuclear Engineering. He notes, however, that a better understanding of certain results is necessary to reduce costs for the researchers' ultimate goal: a magnet weighing 925 tons that will be key to the International Thermonuclear Experimental Reactor. That magnet, in turn, will be part of a total magnet system weighing some 10,000 tons. For more information, contact: Joseph Minervini, at (617) 253-5503 or e-mail: firstname.lastname@example.org.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
