Liquid Robotics' new Wave Glider robot, the SV3 (right, in red) is bigger than its predecessor, SV2 (left, in yellow), shown during sea trials in Hawaii. The SV3 uses stored solar energy for part of its propulsion system, combined with the Wave Glider's unique, wave-powered energy harvesting system. (Source: Liquid Robotics)
Ann, this is a remarkable integration of a number of technologies -- solar, battery, energy storage, conversion of ocean movement. If you gather a number of technologies together no sngle technology has to be perfect. This is a good example.
Oak Ridge National Laboratory has developed a surface preparation method to improve joining carbon composites with aluminum, with potentially far-reaching ramifications for high-volume industrial applications.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
