Cogeneration - Wikipedia

A combined cycle (in which several thermodynamic cycles produce electricity), may also be used to extract heat using a heating system as condenser of the power plant's bottoming cycle.For example, the RU-25 MHD generator in Moscow heated a boiler for a conventional steam powerplant, whose condensate was then used for space heat. A more modern system might use a gas turbine powered by natural …

Wood gas vehicles: firewood in the fuel tank - LOW-TECH

Jan 18, 2010 · The fuel for a wood gas car consists of wood or wood chips (see picture on the left). Charcoal can also be used, but this leads to a 50 percent loss in the available energy contained in the original biomass. On the other hand, charcoal contains more energy, so that the range of the car can be extended. In principle, any organic material can be

Water Research Center - Phosphate in Water

Why Phosphorus Is Important . Phosphorus is one of the key elements necessary for the growth of plants and animals and in lake ecosystems it tends to be the growth-limiting nutrient and is a backbone of the Kreb's Cycle and DNA. The presence of phosphorus is often scarce in the well-oxygenated lake waters and importantly, the low levels of phosphorus limit the production of freshwater systems
