A student team at the University of Virginia's School of Engineering and Applied Science designed a solar-powered wheelchair that won first place in the 2012 World Cerebral Palsy Day "Change My World in One Minute" competition. The chair is powered by a retractable solar panels at the top that can work even in cloudy conditions and were inspired by the retractable roofs on convertible automobiles.

"Alternative energy sources are a given. But a redundant source will only add to the cost and somehow negates the purpose of solar energy's autonomy, don't you think? "
Far911, am not able to follow exactly. I hope you meant about exploring the alternate energy sources. Solar energy won't be available throughout the year, so in such cases we have to explore the other sources like wind/ sea waves (tidal) etc.
@Elizabeth M - True. Batteries are certainly serving as an alternative. However, the solar cell batteries should be sophisticated enough to provide long backup times in order to retain autonomy of this power source.
I will keep track, MyDesign, and write updates as warranted. Actually I was just visiting friends north of Porto here in Portugal, where I live, and my friend's father told me there is a project off the coast of Portugal doing something with waves. Whether it's true or not, I don't know, but I am going to look into it.
"Really? Interesting. I actually wrote about a company that said it can do something like that and are working on technology. http://www.designnews.com/author.asp?section_id=1386&doc_id=262437 I have no idea how they are going to use this fabric to harness ocean waves but I guess we'll see!"
Elizabeth, thanks for the link. Hope you will update with the latest details soon.
