I use this blog to gather information and thoughts about invention and innovation, the subjects I've been teaching at Stanford University Continuing Studies Program since 2005.
The current course is Principles of Invention and Innovation (Summer '17).
Our book "Scalable Innovation" is now available on Amazon http://www.amazon.com/Scalable-Innovation-Inventors-Entrepreneurs-Professionals/dp/1466590971/

CNET has a story and a picture gallery about the Wright brothers' contract with the War Dept:
On September 9 of that year, Orville Wright kept the plane in the air for more than an hour, which was one of the War Department's requirements. The other requirements included carrying a passenger for at least 125 miles at a speed of 40 miles per hour, being steerable in all directions at all times, and landing without damage.
Sounds like an automobile; one that doesn't have to have a road.
Update: the latest DARPA drone that will fly for years at 60,000 feet and higher.
