The process of creating nuclear fusion is a particularly challenging one. It requires producing plasma at temperatures of at least 100 million degrees Celsius (180 million degrees Fahrenheit). That level of heat, seven times hotter than the very center of the sun, is considered the fusion threshold.
The Sparc reactor is the most promising development yet in not just proving that reaching the fusion threshold is possible, but actually harnessing the reaction and generating a seemingly endless supply of carbon-free energy.
Israel lacks roughly 12,000 acres to meet its 30 percent share of renewable energy goal by 2030.But what if land wasn’t a limiting factor for solar energy? What if we could harness the unused surfaces of our lakes and various types of water reservoirs instead? This is the concept behind floating photovoltaics (FPV), otherwise referred to as floating solar––PV modules mounted on buoyant platforms that float on sunlit bodies of water where surface conditions are calm. Xfloat’s system has buoyancy tanks arranged in a grid of connected vessels that control the rotation of the PV tracking tables in unison. https://nocamels.com/2022/05/xfloat-mekorot-solar-panels-energy-floating/
90% of a medical implant's volume can be the battery. Glucose fuel cells, which use the body's own sugars to create electricity are not new, but they have traditionally used materials which pose their own set of challenges. But scientists have developed a new form of glucose fuel cell that is only 400 nanometers thick (thinner than a human hair), by using a ceramic electrolyte which is easy to miniaturize and integrate on a silicon chip, is bio-compatible & can withstand high temperatures (for sterilisation).https://www.tum.de/en/about-tum/news/press-releases/details/37397
Take 500kg of food waste, blast it with oxygen at low heat to speed up decomposition, add no water and no chemicals, and within 24 hours you end up with around 100kg of high-nutrient residual material, free of odour and pathogens, which can be used for fertilizers or in the production of biofuels. Better yet, you simply wheel your food waste bin into the unit, set it and forget it. WasteMaster takes care of the rest, including remote management and trouble-shooting of most operational problems. https://www.greenecotec.com/
