High Quality Content by WIKIPEDIA articles! Leonard G. (Len) Johnson (born June 24, 1953) is an American inventor and entrepreneur who developed and patented a plan that may impact the world`s petroleum economy and provide a solution to global energy demands. Johnson`s patent combines technologies such as desalinization, pipelining, algae farming, and fuel production. In 2008, Johnson completed the United States` first pure biofuel transcontinental flight using bio-butanol in an experimental airplane he personally built. Bio-butanol can be engineered from algae, and may be used as a replacement fuel for turbines as well as reciprocating engines. Johnson was presented with an award by the First Flight Foundation at the base of the Wright Brothers Monument to signify his achievement.
