Typical commercial white paints reject 80%-90% of visible light, but still absorbs ultraviolet light. So it still warms up. Researchers have developed an ultra-white paint which can reject 98% of sunlight, including ultraviolet light. It also releases infrared light, which effectively means the paint can cool itself below surrounding temperatures. The inventors hope it can provide a low-cost, scalable replacement to air conditioning. https://www.purdue.edu/newsroom/releases/2021/Q2/the-whitest-paint-is-here-and-its-the-coolest.-literally..html
"The science of nuclear fusion relies on smashing two atoms together at incredibly high speeds and transforming the energy from that reaction into electricity that can power homes and offices without emitting carbon into the air or dumping radioactive waste into the environment."..."The Department of Energy plans to announce Tuesday that scientists have been able for the first time to produce a fusion reaction that creates a net energy gain — a major milestone in the decades-long, multibillion-dollar quest to develop a technology that provides unlimited, cheap, clean power."...MOREhttps://www.washingtonpost.com/business/2022/12/11/fusion-nuclear-energy-breakthrough/
