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.
Airbus has three hydrogen-powered concepts for 'zero emission' commercial aircraft on the drawing board, two of which are likely to be flying by 2035.
The European airplane maker has previously said hydrogen “holds exceptional promise as a clean aviation fuel and is likely to be a solution for aerospace and many other industries to meet their climate-neutral targets.”
The ZEROe turboprop is capable of carrying up to 100 passengers around 1,000nm, making it best suited to short-range trips.
The ZEROe ‘turbofan’ boosts passenger capacity to the 120-200 bracket while extending range to in excess of 2,000nm: sufficient for a transcontinental jaunt between Australia's east and west coasts.
Small scale wind isn't very popular for residential applications. But a new turbine which mimics the natural spiral design of a nautilus shell might soon provide an alternative to solar. It claims to be quieter but also very efficient, such that one turbine can produce 1,500kwh/annum. In Sydney, an average household (2.4 persons) consumes about 5,200kwh/annum.https://newatlas.com/the-archimedes-liam-f1-urban-wind-turbine/32263/
