A system and methods for heating and cooling are provided. The system may include an energy collector and an adaptive panel connected to the energy collector. The adaptive panel may a radiative cooling layer configured to dissipate heat from the energy collector. The radiative cooling layer may further include a thermo-responsive polymer configured to adjust transparency depending on temperature. The system may include a solar heating layer configured to absorb solar irradiation that passes through the radiative cooling layer and transfer heat to the energy collector.

The object of the present invention is to use the high temperature thermal power stored in the fluid bed in conjunction with thermophotovoltaic (TPV) technology. TPV technology requires thermal emitters at high temperature (>600° C.) to produce electricity from thermal radiation. TPV thermal emitters are located immersed in or exposed to a hot particles fluidized bed, protected by suitable layers of high temperature resistant material, like ceramic or refractory walls. Such high temperature fluidized bed, will provide thermal power to the TPV cells, to produce electricity.
