Chicago Climate Justice activists protesting cap and trade legislation in front of Chicago Climate Exchange building in Chicago Loop. Carbon offsets that fund renewable energy projects help lower the carbon intensity of energy supply. Energy conservation projects seek to reduce the overall demand for energy. Carbon offsets in this category fund ...

Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
The High-frequency Active Auroral Research Program ( HAARP) is a University of Alaska Fairbanks program which researches the ionosphere – the highest, ionized part of Earth's atmosphere . The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high ...
The free-piston engine linear generators can be divided in 3 subsystems: One (or more) reaction section with a single or two opposite pistons; One (or more) linear electric generator, which is composed of a static part (the stator) and a moving part (the magnets) connected to the connection rod.
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, [ 1][ 2] with several later modifications by Köppen, notably in 1918 and 1936. [ 3][ 4] Later, German climatologist Rudolf Geiger (1894–1981 ...
Steam-electric power station. The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of ...
The Climate Registry (TCR) is a non-profit organization governed by U.S. states and Canadian provinces and territories. TCR designs and operates voluntary and compliance greenhouse gas (GHG) reporting programs globally, and assists organizations in measuring, reporting and verifying the carbon in their operations in order to manage and reduce ...
