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.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
3D printing, 4D printing, and various types of additive manufacturing (AM) will get even bigger in 2015. We're not talking about consumer use, which gets most of the attention, but processes and technologies that will affect how design engineers design products and how manufacturing engineers make them. For now, the biggest industries are still aerospace and medical, while automotive and architecture continue to grow.
More and more -- that's what we'll see from plastics and composites in 2015, more types of plastics and more ways they can be used. Two of the fastest-growing uses will be automotive parts, plus medical implants and devices. New types of plastics will include biodegradable materials, plastics that can be easily recycled, and some that do both.
