Gaz de boisLe gaz de bois est un gaz manufacturé ainsi qu'un gaz de synthèse obtenu par pyrolyse du bois. Le gaz de bois est proposé comme gaz d'éclairage en 1800 par l'ingénieur français Philippe Lebon, qui l'appelle alors « gaz hydrogène ». Histoire du gaz manufacturé Entre 1785 et 1786, l'ingénieur Philippe Lebon invente le gaz d'éclairage en France. Ses travaux l'amènent à mettre en évidence les propriétés des gaz de distillation du bois.
Diesel generatorA diesel generator (DG) (also known as a diesel genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of engine generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas. Diesel generating sets are used in places without connection to a power grid, or as an emergency power supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support, and export to the power grid.
Vegetable oils as alternative energyVegetable oils are increasingly used as a substitute for fossil fuels. Vegetable oils are the basis of biodiesel, which can be used like conventional diesel. Some vegetable oil blends are used in unmodified vehicles, but straight vegetable oil often needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity and surface tension, sometimes specially made injector nozzles, increased injection pressure and stronger glow-plugs, in addition to fuel pre-heating is used.
Torréfaction de la biomasseLe principe de la torréfaction pour libérer les arômes de certains aliments (réactions de Maillard) est connu depuis plus de 5 siècles. En revanche, lorsque l’on parle de torréfaction de biomasse (énergie), le concept est beaucoup plus récent et la finalité du traitement n’est pas la même. En effet, l’objectif recherché est non pas la libération d’arômes mais la dégradation des fibres contenues dans la biomasse.
Bourke engineThe Bourke engine was an attempt by Russell Bourke, in the 1920s, to improve the two-stroke internal combustion engine. Despite finishing his design and building several working engines, the onset of World War II, lack of test results, and the poor health of his wife compounded to prevent his engine from ever coming successfully to market. The main claimed virtues of the design are that it has only two moving parts, is lightweight, has two power pulses per revolution, and does not need oil mixed into the fuel.
Propulsion (navire)thumb|Couple de pagayeurs à Bassorah, en Irak. thumb|Le moteur principal d'un pétrolier géant VLCC En construction navale, la propulsion désigne l'ensemble des systèmes qui permettent aux navires et bateaux de se déplacer. Elle est effectuée par un propulseur entraîné par un moteur.
