100-Percent Solar Plane Flies High on Advanced Materials
The world's first 100-percent solar-powered fixed-wing airplane, the Solar Impulse HI-SIA, takes off from California's Moffett Field on the first leg of its cross-country flight this summer. (Source: Solar Impulse)
Glad you liked it, bobj, and thanks for the Shaw quote--he was an early hero of mine, too. That whole "why not?" spirit is what's been so exciting about Silicon Valley (my home "town) and these days, about alternative energy sources, in my opinion. Figuring out how to go to the Moon is often cited as an expression of the daring and ability of the human spirit. I think this airplane--and a few other feats of what looked like impossible technology--can be seen in the same light.
Excellent post Ann and the video was terrific. One of my favorite people in history is George Bernard Shaw. He said the following: You see things; and you say, 'Why?' But I dream things that never were; and I say, "Why not?" One of the reasons folks like us got into engineering was to ask WHY NOT! I fear all too frequently our so-called leaders stop asking why not. We (seemingly) have become a nation without a national goal. At one time, the exploration of space was our vision. Now we seem to be content allowing the politicians to line their pockets while appeasing their "base". Getting reelected is all they strive for.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
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.
