ABSTRACT
There are various ways, other than conventional wind and photovoltaic (PV) systems, to generate electric power. The ultimate source of energy is, of course, the sun. This energy comes primarily in the form of heat. The sun’s heat, in turn, produces wind in the air, marine currents in the ocean, and waves on the ocean surface. All of these carry energy derived from solar energy, which can be converted into electricity using various energy conversion technologies such as the wind and PV systems discussed in the preceding chapters. This chapter covers several other concepts that are being developed. Some have been successfully demonstrated by prototypes and have been proposed for large-scale power generation, seeking potential investors.
