Philo Farnsworth

220px-Philo_T_FarnsworthPhilo Taylor Farnsworth (American; August 19, 1906 – March 11, 1971) At age 14 he worked out the details for an advanced electron tube called an “image dissector”, and demonstrated a working unit in 1927. By 1929 he had further improved the tube and transmitted the first human images (including one of his wife) to a receiver which used a cathode ray tube to display the images. In 1930 an employee of RCA named Vladimir Zworykin visited Farnsworth’s laboratory, was impressed with his image tube technology, and went back to RCA where he made additional advancements to it, allowing it to capture a sharper image with less light on the subject. The combination of these developments resulted in the Image Orthicon tube which was used in television cameras until the 1960’s. In the late 1960’s Farnsworth designed an apparatus called the Farnsworth-Hirsch Fusor to create nuclear fusion. This invention came about from earlier research he did in developing cathode ray tubes for his TV receiver. The apparatus injects “high temperature” ions directly into a reaction chamber in order to produce a fusion reaction. Initially there was hope that it could be used to generate power, but insolvable technical problems prevented it from achieving a net gain of energy. It was successful however, as a neutron generator, and continues to be used for this today. Read more…
