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.

Systems and methods for accurate measurement and transmission of water level parameters during weather events, such as floods, are provided. The solid-state system can effectively measure water level without utilizing moving parts, pumps, or floats and may implement an improved water level determination method that compensates for inherent sources of error. Additionally, the system may be comprised of a network of sensor units that can communicate weather measurements wirelessly via a hybrid mesh network consisting variously of wireless terrestrial radio, cellular, and satellite communication links. By doing so, the status of water level and other environmental parameters may be reported in real time to first responders and emergency planners.

A remote monitoring device and a remote monitoring method thereof are provided. An energy harvesting device converts energy harvested from the surrounding environment into electrical energy for storage. An image capturing device captures an image of a monitored object to generate a captured image. When the power stored in the energy harvesting device meets a preset condition, a control circuit outputs monitoring information based on the captured image.
