I found this site using an addon for firefox called stumble upon, and have been flicking onto it every now and then ever since.
Gizmag its devoted to the latest inventions in all fields from health and wellbeing to electronics to tanks. all split up into sections with the 50 newest articles listed under each heading. some of my favourite things on the site were the personal gyrocopter, and an amusing invention called the girlfriend arm pillow, a half pillow with an arm on one side to snuggle up to. the arm also had a built in alarm and motors so that it rubs your back to wake you up.
