Today, I have included a video of two speeches directly from Thomas Edison. He talks about the creation of the light bulb and the electrical distribution system.  He also speaks of the advances in electronic communications and continuing improvements in electrical systems. He encourages future innovators. The video is about six minutes long.   It is fascinating to look back through time and be able to see him and hear his voice, neither of which would be  possible except for his remarkable innovations.  I understood his perspective better by watching and listening.  Take time to watch and you may learn a litte from the master of innovation.
