Wrightspeed Inc., a developer of range-extended electric vehicle powertrains for medium- and heavy-duty vehicles (earlier post), has unveiled the Fulcrum, a new proprietary turbine generator for use in its Route family of electric powertrains (Route for Class 3-6, Route HD for Class 7-8).
The Fischer–Tropsch process is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbons.These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres.
The only thing between the Mobile River and the most catastrophic coal ash spill the United States has ever seen is a 21-foot-tall dirt and clay embankment. This barrier is somewhere around four miles long and encloses a 597-acre pond filled with toxic ash more than 30 feet deep in places.
Fundamentally, a CANDU nuclear power plant generates electricity like most "thermal" electricity stations (i.e. those that use heat), which includes fossil-fuelled stations as well as most other commercial nuclear stations in the world: Heat is used to boil water, which turns to high pressure steam, which flows through a turbine, which turns an electrical generator, which makes electricity.
Abutment — In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
Introduction Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp viscosity at reservoir conditions. No explicit differentiation is made between heavy oil and oil sands (tar sands), although the criteria of less than 12°API gravity and greater than 10,000 cp are sometimes used to define oil sands.
Heating: Heating, process and system of raising the temperature of an enclosed space for the primary purpose of ensuring the comfort of the occupants. By regulating the ambient temperature, heating also serves to maintain a building's structural, mechanical, and electrical systems.
