A modular firestarter assembly. The modular firestarter assembly includes a number of modular components configured to be able to mount to one another to form the firestarter assembly. The modular components can be broken down to save side. The modular firestarter assembly can be formed from a number of different combinations of the modular components to hold fuel sources and assist in starting a fire.

Embodiments of the invention provide a method of inhibiting precipitation of biodiesel fuel components. The method includes providing a biodiesel fuel composition; providing a copolymer comprising at least first and second polymer units, said first polymer units derived from a carboxylic acid anhydride and said second polymer units derived from an olefin; and blending said copolymer with the biodiesel fuel to form a treated fuel composition. Alternatively, instead of the copolymer, a dialkylene glycol additive can be provided. Embodiments of the invention provide a method of reducing the cold soak filter blocking tendency of a biodiesel fuel composition.

The subject matter of the present invention is a fuel composition which comprises —at least 85% by weight of one or more fractions of hydrocarbons having a distillation range within the range extending from 100 to 400° C. and having a paraffin content greater than or equal to 90% by weight; —at least a first additive consisting of a particular quaternary ammonium salt; and —at least a second additive consisting of a phenolic antioxidant. The subject matter of the invention is also the use of a composition of additives comprising said first and second additives, for improving at least one property of a paraffin-rich fuel composition.

A silicate mixture and a combustion accelerator increase combustion efficiency in a combustion engine. The silicate mixture is formed by mixing a first component including one or two or more materials selected from silicon compounds including silicon, glass, and quartz, and a second component including one or two or more materials selected from materials formed by sintering a silicate mineral at a temperature of 1300° C. or higher and 2000° C. or lower and ores emitting a terahertz wave.
