In this system sunlight is incident on a parabolic trough and focused on metal tube. The parabolic trough has large surface area, more surface area to converge more sunlight and sufficient heat is produced to convert water into steam. In this system, the sunlight energy is converted into mechanical work. Keywords: Sunlight powered steam engine etc. 1. Introduction 1 1.1 Steam Engine: Solar energy is one of the more attractive renewable energy sources that can be used as an input energy source for heat engines. In fact, any heat energy source can be used with the reciprocating engine. The direct conversion of solar power into mechanical power reduces both the cost and complexity of the prime mover. Because of its simple construction, and its manufacture being the same as the reciprocating internal combustion engine, and when produced in a large number of units per year, the steam engine would obtain the economy of scale and could be built as a cheap power source for developing countries. The objective of this article is to provide a basic background and review of existing literature on solar-powered Steam engines. A Steam engine is a machine for converting the heat energy of pressurized steam into mechanical energy, using steam as a medium, or working fluid. When water is converted into steam it expands, its volume increasing about 1,600 times. The force produced by the conversion is the basis of all steam engines.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
