The idea of putting solar panels on ancient ruins, like those in Pompeii, would alarm most people. But an innovative Italian company (Dyaqua) is using a polymer to create realistic "terracotta" roof tiles. These tiles look and function like roof tiles, are installed in a fairly similar manner, but include a layer of PV cells under a protective polymer layer. The polymer aids photon absorption, thus not obstructing the PV cells.https://techxplore.com/news/2022-12-disguising-solar-panels-ancient-roman.html

A low-energy desalination–electrolysis system that can produce green hydrogen directly from seawater has been developed by a team in China. https://newatlas.com/energy/hydrogen-electrolysis-seawater/

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

Form Energy claims that its new technology will be able to store electricity for 100 hours at system costs competitive with legacy

Australia is to fund eight big batteries with a combined 4.2 gigawatt hours of storage capacity in a new funding round designed to

"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/
