POSITIVE THINKING can be found at CORE77, which is a site about industrial design. Do check out the home page and articles. Anyway, one of their contributors, Ray, has a post about a Canadian triumph, "First Human-Powered Helicopter Surpasses Sikorsky Standards, and Why Humans Are Still Superior to Robots". It's a fine account of the Aerovelo team, led by engineers and co-founders Cameron Robertson and Todd Reichert, who nailed it on July 12.
Check out this design concept award-winner, by Omer Haciomeroglu, from Sweden's Umea Institute of Design, for his ERO Concrete Recycling Robot. Haciomeroglu's excellent concept not only takes buildings down in an energy-efficient way, but it systematically recycles as it goes along. Just wait til somebody writes a phone app for a controller.
