For the concerns of environmental issue such as global warming, sustainable and green way to produce energy is highly in demand. Dish Stirling system is one of the most efficient system among others concentrated solar power technologies. However, the system is in disadvantage in terms of cost and reliability when compare to others CSP technologies. In this study, a fundamental prototype of solar powered dish Stirling engine is designed, manufactured, and tested. One component of the prototype which is the power piston is malfunctioning. It was found that the accuracy requirement of the manufacturing of the prototype was high and it requires high skill and experience in machining process.

This paper presents the design and hardware validation of a unique solar powered boiler for powering a desktop scale steam Rankine power cycle. The primary purpose of the desktop Rankine cycle is to improve engineering education through a hands-on laboratory learning approach. Within this context, we have designed and validated a novel, glass-enclosed boiling chamber that generates steam entirely from the sun. Using a solar concentrator, the sun’s heat is focused onto an absorber plate that acts as a heating element. The absorber plate receives solar power via radiation and heats the working fluid through convection. Since this is a direct steam generation boiler, the entering fluid is water that stratifies upon boiling into two steady-state flow regions with both liquid and gaseous phases. A thermal model is developed to characterize the concentrated solar power (CSP), chamber geometry, and heat transfer to the working fluid. A complete solar-to-steam efficiency analysis is presented and validated with the hardware. The boiler’s estimated efficiency is 27.7% for converting typical daily solar irradiance to steam. The solar water boiling process can clearly be observed and is an excellent educational tool for both concentrated solar power as well as Rankine cycle power systems.
