Yamaguchi, N. Sawada, H. Suzuki, H. Ueda, and X. R. Zhang<br/> In this paper, a solar water heater using supercritical carbon dioxide as working fluid is proposed and experimentally studied. For supercritical carbon dioxide, a small change in temperature or pressure can result in large change in density, especially in the state close to the critical point. Thus ... [J. Sol.
