Topic: Fuel Oil

Modern maritime shipping has largely abandoned efficient steam turbines in favor of massive, expensive reciprocating piston engines powered by heavy fuel oil or liquefied natural gas. Statistics from Los Angeles International Airport in 2012 show a consumption of 15 billion gallons of fuel, illustrating the scale of the petroleum industry's wealth extraction. The transition away from coal is described as a move toward more expensive, toxic liquid fuels that benefit oil conglomerates.

Producing biodiesel from waste vegetable oil collected from local restaurants provides a low-cost alternative to commercial fuel, costing approximately 50 cents per gallon. The process involves treating the oil with methanol and lye in simple containers rather than complex manufacturing setups. This method is presented as more reliable than running straight vegetable oil, which often leads to clogged fuel lines and filter issues.
