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.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
