Can air travel ever be sustainable?

Could hydrogen-powered planes be the start of guilt-free flying?

Economist Vicky Pryce says it would make a "huge difference" to achieving clean air travel, however environmentalist Donnachadh McCarthy believes it is "nonsense" and won't tackle global warming.

I can never remember, did British Airways cause the Roman Warming Period, and Air France cause the Medieval Warming Period, OR, was it the other way round?

It is worth research, but it is still a long way to wide application. Maybe let see whether luxury private jet can do it first.

People make me laugh. Where does the Hydrogen comes from?

So many planes fly over my house, three in a row yesterday side by side but I’m an hour away from a small airport and almost 2.5 hrs from London so where did they all take off from? Three flights all going the same way? Who’s in these planes? Where are they all going? This happens every day and honestly the only time we get a clear day is when the planes are strangely absent! Multiple planes and the sky is white by ten am and usually rains for a week after a heavy spraying of whatever is coming out of them.

Reduction is something the greenwashers never suggest 🤪

We need more coal powered vessels for intercontinental travel or big non polluting birds or a good pair of shoes.

Everything is fine, just keep consuming at ever increasing rates & growing the economy & population; let's see what happens.

Shy news needs to talk about Ecosia they are a search search that plants tress

[TurinTuramber]

Yes. Birds have done it for 60 millon years

Yes it will be. It's called field propulsion system. Modulating inertia and gravitational fields.
Big breakthrough coming up in this decade ✌️👽
