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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
