A radiatively cooled solar array, including a downwardly-facing solar cell and a mirror positioned below the solar cell and oriented to direct sunlight onto the solar cell. The assembly also includes a heat sink in thermal communication with the solar cell and disposed opposite the mirror. The heat sink is in radiative communication through Earth's atmosphere with outer space.

A High Energy Beam Processing (HEBP) system provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Signals reflecting process parameters and the quality of the fabricated parts are analyzed by monitoring feedback signals from artifact sources with a process controller which adjusts process parameters. In this manner, fabricated parts are produced more accurately and consistently from powder feedstock by compensating for process variation in response to feedback signals.

An irradiation apparatus may include: an irradiation unit configured to emit a light beam toward a photoelectric conversion unit of a vehicle, the photoelectric conversion unit being configured to convert light energy into electric energy to charge the power storage unit; an adjustment mechanism configured to adjust at least one of a position or a posture of at least one of the irradiation unit or the vehicle; a detector including a light receiving unit configured to receive reflected light of the light beam, and configured to detect a positional relationship between the photoelectric conversion unit and the irradiation unit based on a light receiving result of the reflected light by the light receiving unit; and a controller configured to control the adjustment mechanism based on a detection result of the detector so that the positional relationship between the photoelectric conversion unit and the irradiation unit becomes a predetermined positional relationship.

A self-contained clean energy system includes mirrors that amplify and reflect light received from a battery-powered LED to an angled chamber lined with alternating solar cells and mirrors to power the system and to further power LED lights in similar systems in communication with the clean energy system, which is independent of a power grid.

A solar-powered generator captures solar energy and generates steam with the energy. The generator includes a container formed with an inner spherical wall defining an inner chamber and having an inner reflective surface containing photovoltaic cells and an outer spherical wall defining an outer chamber located between the inner and outer spherical walls. The container is formed to allow for sunlight to enter the inner chamber. An inlet port is configured to allow water to enter the outer chamber and an outlet port is configured to allow steam to exit the outer chamber, whereby sunlight entering the inner chamber through the passage bounces off of the inner reflective surface allowing thermal energy to heat the water in the outer chamber to create steam to generate electricity through an external steam turbine. While simultaneously using radiant energy to be absorbed by photovoltaic cells to generate additional electricity.
