Abstract: A non-ambient pressuring-dependent fire extinguishing chemical that includes a fire retardant, a foament, a preservative, and a carrier. The fire retardant is potassium citrate in a range of approximately 30% to approximately 60% by weight, preferably 42.86% by weight. The foament is sodium bicarbonate in a range of approximately 3% to approximately 10% by weight, preferably approximately 5.04% by weight. The preservative is citric acid in a range of approximately 1% to approximately 3% by weight, preferably approximately 1.68% by weight. The carrier is water, preferably deionized water in a range of approximately 40% to approximately 60% by weight, preferably approximately 50.42% by weight.

Abstract: A dry powdered fire retardant composition for mixing with water on-site comprising dry powdered guar in the range of approximately 40% to approximately 90% by weight and a dry powdered fire retardant salt in the range of approximately 10% to 60% by weight. The dry powdered guar is extremely hygroscopic for mixing on-site. The dry powdered fire retardant salt is a dry powdered mono-ammonium phosphate.

Abstract: An aerodynamic lift mechanism comprises a plurality of aerofoils mounted on two continuous toothed belts which are driven by toothed pulleys. A lever connects each aerofoil to a continuous member which substantially follows the contour of the belts but which is movable relative to the belts. Movement of the continuous member alters the angles of attack of the aerofoils.
