The winter has set in and the temperatures have dropped. When going out you need to wear at least two pares of thermal socks just to stop your feet freezing, but that only just about keeps you feet from becoming ice. This is why we all need self heating socks (dot)goodidea.
The technology is really simple. The socks have piezo strips that when you walk they bend and generate power. Sadly this will not generate enough power to heat the socks, but it will generate enough power after a few minutes to light an LED. This is what we will do. As you walk along the system charges. When there is enough power the controls on the generator you are pulling behind you are illuminated. This allowing you to find the start button. Then the power generated is fed back to the heating elements in the socks.
Naturally we are looking at ways of reducing the size of the generator.
Winter warmer win. Are you in?
