Masdar Institute of Science and Technology is a multi-faceted research center, which although small at this time, seems to be fairly prodigious in the output of patents, patents pending and academic papers. The Institute heads a program to use “coastal seawater to raise fish and shrimp for food, whose nutrient-rich wastewater then fertilizes oil-rich halophyte plants that can be harvested for aviation biofuel production.”  Halophytes, as those who’ve listened to or read Dennis …

Measuring Up To Standards

ASTM International, formerly known as the American Society for Testing and Materials, develops “international consensus standards” for many industries, using input from its members in many fields and disciplines.  Their D-7566-11 “Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons” governs what can be put into jet and turbo-prop aircraft.  Updated in July 2011, it now allows the use of biologically-derived fuel “without the need for special permissions,” according to SAE International, itself a standards organization, and as reported by Patrick Ponticel. United Airlines was quick to take advantage of the revised standard, using “Solazyme-supplied algae oil that was refined into jet fuel by Honeywell’s UOP division near Houston. The blend used for the November 7, Boeing 737-800 flight was 40-percent …
