I'm presently pursuing my undergraduate in Mechanical Engineering, and I need help in choosing a thesis topic in Renewable Energy(as that is what I want to pursue my future in). My university is not equipped with state of the art labs, though they manage to meet the requirements of having the most basic ones. This being said I plan to publish a paper too, can I can submit one without having to conduct complex experiments. Do I need to find something substantial to publish a paper? Its a choice between Solar, Wind and Hydroelectric(Run-of-the-river).
