A modular solar air heater comprises an extruded metal frame having fingers operable to secure a glazing, an absorber, and an insulating back sheet to the frame. The heater may also operate as a cooler. The heater further comprises an active air circulation system, such as a fan, which may be coupled with an air inlet of the heater. The heater has an air outlet and may further include a bypass channel to direct the airflow alternatively through one or both the bypass channel and the air outlet. A heating element and a cooling element may be coupled with the air outlet to further heat and also cool the air through the air outlet, respectively. A photovoltaic panel may be included to provide electrical power to the heater.

The water heater includes a main body and a secondary tank. The main body encloses a receiving space and absorbs solar energy to heat water therein. The main body has a first inlet, a first outlet, and a steam outlet. The secondary tank includes a tank having a second inlet, a second outlet, and a steam inlet. The second outlet communicates with the first inlet of the main body via an inlet pipe, and the steam inlet communicates with the steam outlet of the main body via the steam pipe. Water enters the tank via the second inlet and enters the main body via the inlet pipe. Steam produced by the heated water in the main body enters the tank via the steam pipe to be further discharged or to condense into liquid water. The liquid water enters the main body again via the inlet pipe.

Systems and methods for generating electrical power using a solar power system that comprises a pressurized closed loop pipe containing a transfer liquid extending between a solar collector and a heat exchanger. The transfer liquid is heated by the solar collector and gives up its thermal energy at the heat exchange to produce steam. The system also includes a source of geothermal energy and a source of natural gas. The geothermal energy in the form of heat separates the natural gas from the ground water in a separation tank. At the resulting heated ground water from the separation tank is connected to the heat exchanger to supplement thermal energy from the solar collector.

A solar energy module includes a photovoltaic unit including a layer of one or more solar cells. The layer has a front side exposed to incident radiation and an opposite back side. The solar energy module also includes a thermal unit thermally coupled to the back side of the layer of one or more solar cells. The thermal unit includes one or more channels through which a thermal transfer fluid flows, wherein a portion of the incident radiation is converted into electricity by the layer of one or more solar cells and a portion of the incident radiation is simultaneously converted to heat for increasing the temperature of the thermal transfer fluid. The solar energy module also includes a heating system to further increase the temperature of the thermal transfer fluid. The heating system is powered by electricity generated by the one or more solar cells. The solar energy module further includes a controller for controlling the relative amounts of heat and electricity output by the solar energy module by controlling the amount of electricity produced by the one or more solar cells that is diverted to the heating system for increasing the temperature of the thermal transfer fluid.

Techniques, systems, apparatus and material are disclosed for generating oxygenated fuel. In one aspect, a method of producing an oxygenated fuel from biomass waste for use in a combustion system includes dissociating the biomass waste to produce one or more carbon donors. The biomass waste produced carbon donors are reacted with an oxygen donor to produce the oxygenated fuel comprising oxygenated carbon. Reacting the carbon donors with the oxygen donors includes applying waste heat recovered from an external heat source to the reaction of carbon donors and oxygen donor. The oxygenated fuel is combusted in the combustion system.

Reactor vessels with pressure and heat transfer features for producing hydrogen-based fuels and structural elements, and associated systems and methods. A representative reactor system includes a first reaction zone and a heat path, a reactant source coupled to the first reaction zone, and a first actuator coupled to cyclically pressurize the first reaction zone. A second reaction zone is in fluid communication with the first, a valve is coupled between the first and second reaction zones to control a flow rate therebetween, and a second actuator is coupled in fluid communication with the second reaction zone to cyclically pressurize the second reaction zone. First and second heat exchangers direct heat from products to reactants in the reaction zones. A controller controls the first and second actuators in a coordinated manner based at least in part on a flow rate of the second product from the second reaction zone.

Reactors for conducting thermochemical processes with solar heat input, and associated systems and methods. A system in accordance with a particular embodiment include a reactor having a reaction zone, a reactant source coupled in fluid in communication with the reactant zone, and a solar concentrator having at least one concentrator surface positionable to direct solar energy to a focal area. The system can further include an actuator coupled to the solar concentrator to move the solar concentrator relative to the sun, and a controller operatively coupled to the actuator. The controller can be programmed with instructions that, when executed, direct the actuator to position the solar concentrator to focus the solar energy on the reaction zone when the solar energy is above a threshold level, and direct the actuator to position the solar concentrator to point to a location in the sky having relatively little radiant energy to cool an object positioned at the focal area when the solar energy is below the threshold level.
