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/
