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.
According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.
Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation
call this deep learning.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
