  2. Compressed natural gas - Wikipedia

    en.wikipedia.org/wiki/Compressed_natural_gas

    Compressed natural gas vehicles require a greater amount of space for fuel storage than conventional petrol-powered vehicles. Since it is a compressed gas, rather than a liquid like petrol, CNG takes up more space for each GGE (petrol gallon equivalent). However, the cylinders used to store the CNG take up space in the trunk of a car or bed of ...

  3. AP Human Geography - Wikipedia

    en.wikipedia.org/wiki/AP_Human_Geography

    Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

  4. Autogas - Wikipedia

    en.wikipedia.org/wiki/Autogas

    There are two types of autogas equipment and autogas stations as well: LPG (propane-butane mix) and compressed natural gas (CNG, methane). Natural gas is stored at a higher pressure than LPG (200 bar vs. 10 bar for LPG). The main consumer of LPG is commercial light-weight cargo transport (so as GAZelles in Russia are mostly LPG-powered).

  5. Natural gas vehicle - Wikipedia

    en.wikipedia.org/wiki/Natural_gas_vehicle

    A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas (LPG), NGVs rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source.

  6. Motor fuel - Wikipedia

    en.wikipedia.org/wiki/Motor_fuel

    A motor fuel is a fuel that is used to provide power to the engine of motor vehicles — typically a heat engine that produces thermal energy via oxidative combustion of liquid or gaseous fuel and then converts the heat into mechanical energy through reciprocating pistons or gas turbines.

  7. Compressed-air car - Wikipedia

    en.wikipedia.org/wiki/Compressed-air_car

    Compressed air cars are emission free. They also do not require a connection to the electric grid. A wind turbine or other renewable energy source can directly drive an air compressor or hydraulic pump. Compressed air cars do not rely on petrol stations or an electric grid. While centralized infrastructure might not be needed, it is an option.

  9. Propellant - Wikipedia

    en.wikipedia.org/wiki/Propellant

    Liquefied gas propellants are gases at atmospheric pressure, but become liquid at a modest pressure. This pressure is high enough to provide useful propulsion of the payload (e.g. aerosol paint, deodorant, lubricant), but is low enough to be stored in an inexpensive metal can, and to not pose a safety hazard in case the can is ruptured.
