Solar energy plays a leading role in the global effort to reduce carbon emissions and is considered to be a clean and efficient source of electricity. At present, most of the solar energy systems on the market have two major drawbacks: the need to occupy large areas of land and the high cost of solar cell manufacturing and maintenance. Although these problems have hindered the solar industry from being widely promoted in countries without government subsidies, people are still looking for new ways to expand the solar market. The United States "Science Daily" recently reported that a new technology will overcome these challenges, which is: Floating solar farms. This innovative solar energy production technology, developed in cooperation with France and Israel, introduces solar energy production into a new paradigm. A year ago, just after the R&D design process was over, the design team began to assemble the prototype and plans to start using it in September 2011. The test site was selected in Cadarache, in the southeastern part of France. This area is in a strategic location on the French grid, and the local hydropower station can provide the open water needed for the assembly test of the system. On-site operations will take nine months to evaluate the system's performance and capacity under seasonal and hydrological changes during this period. Researchers believe that by June 2012, they will receive all the data needed to bring the technology to market. When leading PV companies work hard to find land for the construction of solar farms, the project team explores the potential for building solar power plants on the water surface. The water area where the electric field is built is not a nature reserve, a tourist resort, or the open sea, but an industrial or other-purpose water area. Therefore, water-based solar farms will not have a negative impact on nature. “This is a win-win situation,†said Dr. Kassel, head of the research team. “Water used in power generation and industrial and agricultural production in many reservoirs can also be used to install solar power plants.†After solving the space problem, the team also paid attention to cost issues. “This looks great and combines solar energy and water to generate electricity, but we also need to prove that this model can be economically successful in the long term,†Dr. Kassel explained. Developers are reducing the cost of the technology in two ways. The first is to reduce the number of solar cells while maintaining power production, thanks to the use of a mirrored solar concentrating system. Second, the design team used a creative water cooling system in the floating solar field. This cooling method makes it possible for solar photovoltaic systems to still use silicon-based solar cells. There is a problem of overheating of the silicon battery during use. To maintain the normal operation of the system, it is necessary to assist the cooling system. Compared to ordinary batteries, this kind of battery has higher power generation efficiency. Based on the above characteristics, this water-based solar energy system has both reliability and economy. In order to make this technology more efficient and ready for the market, this system adopts a modular design, in which a solar panel can be installed with different numbers of the same power generation module according to the power demand. Each module standard produces 200 kilowatts of electricity. Simply increasing the number of modules can increase the total power generated by the production platform. The team is also working to reduce the environmental impact of this technology. This technology can ensure the exchange of oxygen between the water body and the air, ensuring that enough oxygen can maintain the survival of underwater animals and plants. Dr. Kassel stressed that "a phased goal in operation is to closely observe the potential impact of the technology on the environment with the assistance of experts. Moreover, preliminary investigations have shown that water quality and plant and animal systems have not been adversely affected by the environment. We have also taken into account this factor in the selection of production materials."

New Paradigm of Solar Energy Production Technology——Floating Electric Field
Emergency lighting luminaires are fixtures that are specifically designed to provide illumination in the event of a power outage or emergency situation. These luminaires are equipped with a backup power source, such as a battery or generator, that allows them to continue providing light even when the main power supply is not available.
Emergency lighting luminaires are commonly used in buildings, such as offices, schools, hospitals, and public spaces, to ensure that occupants can safely evacuate during emergencies. They are typically installed in hallways, stairwells, exits, and other critical areas where visibility is crucial.
These luminaires come in various shapes, sizes, and designs to suit different applications and aesthetics. They are often equipped with features like adjustable brightness levels, automatic testing and monitoring systems, and long-lasting LED bulbs for energy efficiency.
Overall, emergency lighting luminaires are essential safety devices that provide peace of mind and security in the event of unexpected power failures or emergencies.
