Bill uses a replica of the point contact transistor built by Walter Brattain and John Bardeen at Bell Labs. On December 23, 1947 they used this device to amplify the output of a microphone and thus started the microelectronics revolution that changed the world. He describes in detail why a transistor works by highlighting the uniqueness of semiconductors in being able to transfer charge by positive and negative carriers.

Bill explains the essential principles of a lead-acid battery. He shows the inside of motorcycle lead-acid battery, removes the lead and lead-oxide plates and shows how they generate a 2 volt potential difference when placed in sulfuric acid. He explains how the build up of lead sulfate between the plates will make the battery unusable if it discharged completely, which leads him to a description of how to make a deep cycle battery used for collecting solar energy.

We all know Thomas Edison, his accomplishments are legendary, over 1000 patents were issued to this prolific inventor. Nikola Tesla, noted Serbian academic, was another inventor from the same period, trained in Europe as an engineer, he emigrated to the United States where he never attained the stature of Edison but arguably accomplished more. He is the inventor of our modern electrical power grid. This video summarizes this accomplishment and the role that both Edison and Tesla played in this accomplishment.
