While visiting MIT for graduation, I walked right past a new prototype-scale solar-thermal power plant that a group of students had built in one of the Institute’s outlaying parking lots. Given my recent coverage of the Nevada Solar One power plant (see Nevada Solar One Demonstrates Scalability of Solar Thermal Energy), I could not resist posing for a photo (below).
Fortunately, someone familiar with the project was standing guard to ensure latecomers rushing to park in the lot for gradation did not inadvertently hit the installation. So, I was able to learn a little about the power plant before dashing off to receive my Ph.D.
This solar-thermal plant was specifically designed for use in developing counties and was built using old, recycled automobile parts. The four parabolic mirrors concentrate solar energy on the black-painted pipes that run along the foci of each mirror, heating the fluid inside. In the configuration pictured, the system was set up with a heat exchanger (which I am standing in front of, unfortunately) to deliver hot water. A turbine could also be added to extract energy from the collected heat.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
