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.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
