A steam car is a car that has a steam engine. Wood, coal, ethanol, or others can be used as fuel. The fuel is burned in a boiler and the heat converts water into steam. When the water turns to steam, it expands. The expansion creates pressure. The pressure pushes the pistons back and forth. This turns the driveshaft to spin the wheels forward. It works like a coal-fueled steam train, or steam boat. The steam car was the next logical step in independent transport.
Steam cars take a long time to start, but some can reach speeds over 100 mph (161 km/h) eventually. the late model doble could be brought to operational condition in less than 30 seconds, and were fast, with high acceleration, but they were ridiculously expensive.
A steam engine uses external combustion, as opposed to internal combustion. Gasoline-powered cars are more efficient at about 25-28% efficiency. In theory, a combined cycle steam engine in which the burning material is first used to drive a gas turbine can produce 50% to 60% efficiency. However, practical examples of steam engined cars work at only around 5-8% efficiency.
The best known and best selling steam-powered car was the Stanley Steamer. It used a compact fire-tube boiler under the hood to power a simple two-piston engine which was connected directly to the rear axle. Before Henry Ford introduced monthly payment financing with great success, cars were typically purchased outright. This is why the Stanley was kept simple; to keep the purchase price affordable.
Steam produced in refrigeration also can be use by a turbine in other vehicle types to produce electricity, that can be employed in electric motors or stored in a battery.
Steam power can be combined with a standard oil-based engine to create a hybrid. Water is injected into the cylinder after the fuel is burned, when the piston is still superheated, often at temperatures of 1500 degrees or more. The water will instantly be vaporized into steam, taking advantage of the heat that would otherwise be wasted.

Ethnic and political rivalries

A Balkan war between Austria-Hungary and Serbia was considered inevitable, as Austria-Hungary’s influence waned and the Pan-Slavic movement grew. The rise of ethnic nationalism coincided with the growth of Serbia, where anti-Austrian sentiment was perhaps most fervent. Austria-Hungary had occupied the former Ottoman province of Bosnia-Herzegovina, which had a large Serb population, in 1878. It was formally annexed by Austria-Hungary in 1908. Increasing nationalist sentiment also coincided with the decline of the Ottoman Empire. Russia supported the Pan-Slavic movement, motivated by ethnic and religious loyalties and a rivalry with Austria dating back to the Crimean War. Recent events such as the failed Russian-Austrian treaty and a century-old dream of a warm water port also motivated St. Petersburg.[25]
Myriad other geopolitical motivations existed elsewhere as well, for example France's loss of Alsace and Lorraine in the Franco-Prussian War helped create a sentiment of irredentist revanchism in that country. France eventually allied itself with Russia, creating the likelihood of a two-front war for Germany.
