| contents | A quintessential source of heat, the Sun radiates toward the Earth a power ten thousand times greater than humanity's energy needs. Harnessing this energy bounty, however, requires capturing and converting sunlight. Today, this conversion can be achieved through several families of technologies at varying stages of maturity: photovoltaic solar, thermal, concentrated solar power, and more. While their applications differ, all these technologies must meet common fundamental constraints, and as Carnot proposed, one can 'consider in all its generality the principle of producing motion through heat' from the Sun. However, unlike traditional 'heat engines,' the coupling with the hot source here is radiative, introducing specific constraints that must be accounted for. In this presentation dedicated to radiative machines, you will encounter familiar terms as well as particular expressions that will provide the keys to understanding solar technologies |
