Some algae species are 50% or more lipid oil by weight. This oil may be pressed from the algae and refined into diesel. The process for extracting algal oil, at its simplest level, resembles pressing an olive. Up to 75% from the oil might be squeezed from algae using a simple mechanical press. Hexane might be used being a solvent to raise extraction up to 95%. Once extracted, the oil is refined through transesterification. A catalyst including sodium hydroxide is combined with alcohol to make biodiesel and glycerol.
The Red Baron, whose real name was Manfred Albrecht Freiherr von Richthofen, was the most famous German flying ace of World War I. He had an incredibly short flying career, which spanned about 1 / 2 of World War I, and died in the age of 25 in April 1918 after being shot down over Morlancourt Ridge, at the Somme. He was officially credited with 80 air combat victories, though further overview of data shows how the number may have been better 100. As for Red Baron airplanes, all were Fokkers, or Albatroses, plus one Halberstadt D.II.
