judgecorp writes "MIT professor Hugh Herr describes how technology can end disability in 50 years — with a big incentive from the need to support injured war veterans. A champion climber, Herr lost both legs below the knee, returned to climbing and designed improved climbing prostheses. From the article: 'Herr believes the work he is doing won’t just have humanitarian benefits. There’s money to be made too. And if there’s a market here, it means more people will receive help. Despite all the horrors and injustices the Iraq and Afghanistan wars spawned, they have helped make the biomechatronics industry a lot more viable. Back in 2007, Herr gave Garth Stewart, a 24-year-old Army veteran who lost his left leg below the knee during the conflict in Iraq, a bionic ankle. It used tendon-like springs and an electric motor to provide support for Stewart.'"
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
