Steam's "Big Picture" mode is more optimized for a larger screen with a larger, simpler interface that mimics the Steam Deck interface and is easily navigable with either a controller or mouse. Steam's "Big Picture" mode was announced in 2011; [137] public betas started in September 2012 and were integrated into the software in December 2012. [138]
Valve’s Steam platform launched all the way back in 2003. For much of that time, it saw slow and steady growth as it grew from a place where you could buy Half-Life games to the PC’s default ...
Steam engines and steam turbines use the expansion of steam to drive a piston or turbine to perform mechanical work. The ability to return condensed steam as water-liquid to the boiler at high pressure with relatively little expenditure of pumping power is important.
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

1st century AD – Hero of Alexandria describes the Aeolipile, as an example of the power of heated air or water.The device consists of a rotating ball spun by steam jets; it produced little power and had no practical application, but is nevertheless the first known device moved by steam pressure.
Steam was a familiar technology, adapted well to local facilities, and also consumed a wide variety of fuels; this led to its continued use in many countries until the end of the 20th century. Steam engines have considerably less thermal efficiency than modern diesels, requiring constant maintenance and labour to keep them operational. [96]
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
