My comments about passive solar should also be accompanied by one about active solar, AKA solar cells and panels as currently designed and built. And that's the fact that there's more than one way to build a solar cell. Some are flexible, such as this one:http://www.designnews.com/author.asp?section_id=1392&doc_id=248975 as well as another that we'll be publishing a post on soon. So the application of such cells to windows and/or building surfaces of various kinds could take care of the urban density problem.
John, Yes, we know that wind farms are not great to look at -- and that they kill birds and bats. Here's an idea for the industry. Imagine placing many fan blades on a chain that runs on a vertical oval or circular track. The track could have a wire grid around it to prevent bird strikes. If oval, it could lie at a low profile near the ground.
Thanks for clarifying your question. I'm not sure the sun stops shining much in those islands. When it does, backup is provided by the generators, run on coconut oil. They also handle battery recharging.
This is a terrific development. Hats off to a small island nation for being willing to take on this grand experiment. It would be nice to keep tabs on this operation over the next few years. Especially to see how it holds up to salt exposure and tropical storms.
I think this is admirable. The three islands should be commended. They saw a problem. They made their plans for solution. They actually did something about the problem and the results are tangible. Now, for better or worse, they will have to live with the solution but having a system in which 150% of their electrical needs are met seems to be proof their solution was workable. (Ann-would you mind sending your post to Congress--and maybe the Executive branch. They might see examples of government working together to do SOMETHING POSITIVE.)
Also Ann, do you know the name of the firm that designed the system? Possibility the University Fiji???? Great post.
bobjengr, I didn 't see the name of the design firm in the source material. However, you might check the links we gave in the article to the website of PowerSmart, and to the feasibility report. It may be identified in one of those sources. (And I agree about those letters to Congress.)
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
