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.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
