Why haven’t the aviation industry come up with a cleaner way to fly?
It may sound like science fiction but in fact, the future of aviation is already here.With funding from the UK government, BAE Systems has developed a working, hydrogen-fuelled air breathing rocket engine that will power planes capable of travelling not just at supersonic speeds like Concorde but hypersonic, like the Space Shuttle.Its only emissions would be water, just like a fuel cell car.We’re a long way from seeing such a plane landing at an airport near you anytime soon, but the engine at least is a current, working reality.
Destruction is a man’s will…Nevertheless, Prevention is also a man’s will. Its a man’s choice to choose between Destruction and Prevention

For smaller planes, electric planes are already in our skies; Israeli’s Eviation has a fully electric plane for 9 passengers with a range of 1 000km. Boeing is backing Zunum Aero to build an already designed and theoretically possible 50 seater fuel-cell powered plane with a range of 400 miles. Easyjet is working with Wright Electric to have at least 10 electric planes on its European short haul routes by 2030.
More promising still are electrofuels made from hydrogen created from water which is then bound with carbon.Such fuels can be used with minor modifications in existing jet and prop engines with virtually zero emissions. Currently these fuels are three to four times the price of kerosene but they are already being used in planes flying today, as much as 5%.
Generally speaking, though, we’re a very long way away from clean flights.
