Steam is a video game digital distribution service and storefront managed by Valve.It was launched as a software client in September 2003 to provide game updates automatically for Valve's games and expanded to distributing third-party titles in late 2005.
Type of steam generator unit used in coal-fired power plants. The steam generator or steam boiler is an integral component of a steam engine when considered as a prime mover. However it needs to be treated separately, as to some extent a variety of generator types can be combined with a variety of engine units.
Herreshoff steam generator in a Peruvian torpedo boat of 1879. A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873.
The free-piston linear generator (FPLG) uses chemical energy from fuel to drive magnets through a stator and converts this linear motion into electric energy. Because of its versatility, low weight and high efficiency, it can be used in a wide range of applications, although it is of special interest to the mobility industry as range extenders for electric vehicles.
The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side.
A compound turbine is a steam turbine in which there are two casings, a high-pressure casing and a low-pressure casing, operating in concert to extract work from a single source of steam. The steam is partially expanded in the high-pressure casing, then exhausted to the low-pressure casing.
Edward "Ted" Pritchard (28 August 1930 – 16 August 2007) was an Australian mechanical engineer, inventor and developer of small scale modern steam engines.Pritchard was obsessed by the virtues of modern steam as compared to the internal combustion engine.
A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
