An inventor brings you a device. she claims that it will collect solar energy at 120c and that each 1m^2 of collecting surface will provide power from the attached engine at a rate of 0.5 kw/m2. you know that the solar energy on a clear day around noon in atlanta does not exceed 1 kw/m2. you are asked to decide the following a) what is the first and 2nd law of thermodynamics? b) does the proposed device violate the first law? why or why not? list any assumptions you may make. c) does it violate the second law? why or why not? list any assumptions you may make. d) could the device operate as advertised if you used the device somewhere else instead of atlanta? what would the requirements on the climate of that place?
