in battery technology, driven along by the electrification of road transport, are helping air taxis and other small electric aircraft get airborne. But even the best lithium-ion cells are still far from being able to power the workhorses of civil aviation: short-haul airliners carrying 150 or so passengers. An electric version would not be able to rise from the ground, because of the weight of the batteries required to drive its engines.
For its flight tests, Project 804 is converting a Bombardier Dash 8-100, a 40-seat aircraft powered by a pair of turboprops. These are jet turbines that turn a propeller at the front of the engine via a gearbox. Project 804’s flight trials will help work out both how such hybrid engines could replace turboprops on existing aircraft and how they might be used by entirely new models. As the downsized turbines would be optimised for cruising, they would themselves have better fuel economy. Working with the electric motor, the hybrid combination on a regional turboprop airliner, which typically flies routes of around one hour’s duration, would result in fuel savings of at least 30%, says Mr Eremenko.
With the collapse in price of drones & the propensity of people to direct technology to violent ends there will be no commercial airlines to speak of in 10 years time. Only governments will be able to insure the risk. The world is about to get bigger for the first time in decades
The recent cleanup of Everest was in preparation of the property to build a battery replacement station for future airliners
Could could could...
Distributed engines or motors may not fail at the same time Maybe distributed power with 50percent redundancy is a good ploy design
🤣🤣🤣🤣

UTC RollsRoyce Airbus Airplanes during descent do not behave like cars in braking. Braking cars throw away kinetic energy through brake heat. Airplanes DO NOT throw away potential energy (altitude) while descending. It is used to fly forward, with no engine thrust=gliders
But can they go further then 80 Km or so before recharging. Bit tongue in cheek 😉
alllibertynews So AOC is right again?
'What do you mean, 'you forgot to bring the charger''?
Hot.
Yes, do this. But until planes are *fully* harmless to the atmosphere, there's a choice to limit flying to 'only when necessary'. And if that conflicts with the industry's perceived need to grow its business, then aviation's leaders need to consider morality.
Toyota ToyotaMotorCorp TIME elonmusk Tesla MIT They will fail .. either by performance shortages, or being too expensive, or losing out to better simpler cheaper more efficient tech. Fact. [Bad investment this .. people haven't thought it through]
Yes, I quite agree with you😀💋
Are we gonna fly on the back of archaeopteryx?
