Best Inventions of the Year

Time magazine had their list of the best 25 inventions of the year in this weeks issue. All were great. Some of my favorites were:

1. The motion activated screwdriver - it has an internal gyroscope that senses which way you turn it. Tilt it just 1/4 inch to the right and it screws clockwise to tighten. That's really handy.
2. Flyknit racer - Nike has developed a way of knitting thread into a single layer for the entire sneaker. Thus it's lighter, gives a precision fit, and even reduces waste in the factory.
3. Self inflating tires - they have an internal pressure regulator that can open a valve to a pumping tube and, as the wheel turns, the flattened part squeezes air from the tube into the tire. When optimal tire pressure is reached it closes. All without the driver even knowing anything was wrong. Amazing!
