Nancy, I had that thought, too, even before I saw the photos. One reason is because of the background info I read for the story of the perpetual-flight plane:
Ann, that was my first thought, when I read the title of your article: that the plane would be built like a glider. Especially with these preliminary designs - that only makes sense...not only for general power consumption given the general inefficiency of solar power, but if there is not enough power, the plane can still safely fly...and land!
AnandY, that type of design detail may be available on the Solar Impulse website. I find it interesting that another solar-powered airplane, the prototype Electric High Altitude Solar-Powered Aircraft (ELHASPA), which we describe here http://www.designnews.com/author.asp?section_id=1386&itc=dn_analysis_element&doc_id=264353&image_number=11 also has very long, thin wings, which are typical of aircraft designed to glide.
Elizabeth, I also was happy to see the lighter alternative materials being used. And I agree that solar power would be ideal for just about everything, if it were feasible in each case. Advances like this one show us that a lot is possible when you combine brains, talent, funding, expertise and willpower.
I really like this idea of a solar plane, thanks for this coverage, Ann. I am impressed at how the use of lighter, advanced materials makes this type of flight possible. Using alternative fuels for airplane travel is really good, but solar power, in my opinion, would be even better.
@Ann, thanks for informative post. Cost of flight reaching all time highs due to a various factors like fossil fuels costs, cuts in government subsidies. There is a need for alternatives energy resource. Solar energy is potential solutions to cut costs.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
