    The Stanley Motor Carriage Company was an American manufacturer of steam-engine vehicles; it operated from 1902 to 1924. The cars made by the company were colloquially called Stanley Steamers, although several different models were produced.

  • Hydrogen vehicle

    The 2015 Toyota Mirai is one of the first hydrogen-fuel-cell vehicles to be sold commercially. The Mirai is based on the Toyota FCV concept car (shown). A hydrogen vehicle is a vehicle that uses hydrogen as its onboard fuel for motive power. Hydrogen vehicles include hydrogen-fueled space rockets, as well as automobiles and other transportation vehicles. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or, more commonly, by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy. , there are three models of hydrogen cars publicly available in select markets: the Toyota Mirai, the Hyundai Nexo, and the Honda Clarity. Several other companies are working to develop hydrogen cars. As of 2014, 95% of hydrogen is made from natural gas. It can be produced by thermochemical or pyrolitic means using renewable feedstocks, but that is an expensive process. Renewable electricity can however be used to power the conversion of water into hydrogen: Integrated wind-to-hydrogen (power-to-gas) plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with hydrogen production using natural gas. The drawbacks of hydrogen use are high carbon emissions intensity when produced from natural gas, capital cost burden, low energy content per unit volume at ambient conditions, production and compression of hydrogen, and the investment required in filling stations to dispense hydrogen.

  • Steam car

    serch.it?q=Steam-car

    Stanley Steam Car (1912) White touring car (1909) A steam car is a car (automobile) powered by a steam engine. A steam engine is an external combustion engine (ECE) where the fuel is combusted away from the engine, as opposed to an internal combustion engine (ICE) where the fuel is combusted within the engine. ECEs have a lower thermal efficiency, but it is easier to regulate carbon monoxide production. The first steam powered vehicle was supposedly built in 1672 by Ferdinand Verbiest, a Flemish Jesuit in China. The vehicle was a toy for the Chinese Emperor. While not intended to carry passengers, and therefore not exactly a "car", Verbiest's device is likely to be the first ever engine-powered vehicle. The first real experimental steam powered cars were built in the late 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam, around 1800, that mobile steam engines became a practical proposition. By the 1850s it was viable to produce them commercially: steam road vehicles were used for many applications.
