No Lead Problem In Kansas
This has potential in spacecraft manufacturing…
According to Czinger, 3D printing transforms everything by changing the way the structural components of cars are fabricated. Currently cars are pieced together on long assembly lines inside large factories that use massive amounts of energy. Even the most fuel-efficient car has a large carbon footprint before ever leaving the plant.Czinger and his team’s approach was to take the large plant out of the equation. To accomplish this they printed the modular pieces that are used to connect carbon rods that make up the Blade’s chassis.”The 3D printed chassis is only 102 pounds and has the same strength and safety protection as a frame made out of steel,” said Brad Balzer, the lead designer on the project.By using carbon fiber instead of steel or aluminum for the body, the entire vehicle only weighs 1400 pounds (635kg), giving it twice the weight to horsepower ratio of a Bugatti Veyron.
Aurorae are detected from all the magnetized planets in our SolarSystem, including Earth. They are powered by magnetosphericcurrent systems that lead to the precipitation of energetic electronsinto the high-latitude regions of the upper atmosphere. In the caseof the gas-giant planets, these aurorae include highly polarizedradio emission at kilohertz and megahertz frequencies producedby the precipitating electrons, as well as continuum and line emis-sion in the infrared, optical, ultraviolet and X-ray parts of thespectrum, associated with the collisional excitation and heatingof the hydrogen-dominated atmosphere. Here we report sim-ultaneous radio and optical spectroscopic observations of an objectat the end of the stellar main sequence, located right at the bound-ary between stars and brown dwarfs, from which we have detectedradio and optical auroral emissions both powered by magneto-spheric currents.
