Foot-pound (energy) Foot-pound (energy) The foot pound-force (symbol: ft⋅lbf or ft⋅lb) is a unit of work or energy in the Engineering and Gravitational Systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule. The foot-pound is often used to specify the muzzle energy of a bullet in small arms ballistics, particularly in the United States. "Foot-pound" is also used as a unit of torque (see "pound-foot (torque)"). In the United States this unit is often
Home Energy Resources Unit Home Energy Resources Unit The Home Energy Resources Unit or Home Energy Recovery Unit (HERU) is a prototype kitchen appliance which is claimed to use household waste to generate energy. Household waste, both organic and inorganic, is placed into a main chamber. Plastic and cardboard packaging as well as food waste can be inserted as fuel, and the waste does not need to be sorted or separated. It then goes through an eight-hour cycle. The chamber containing the waste is heated to 100° celsius to evaporate water and remove oxygen. The temperature is then increased and pyrolysis takes place. Oxygen
