Can we please stop all planes that use fossil fuels?
i wish, batteries are still too heavy to replace jet fuel, hydrogen could work weight wise, but too low density and you just don't have space in an airplane (you could design one but it'll be too big and have too much drag).
best possibility for now is biofuels. basically plug and play.
better yet, replace all major overland routes with high speed rail, much cheaper than flying anyways.
Sail boats work great.
not realistically with our current technology
Lol we had this tech for centuries
We’ve had batteries with better energy density than fossil fuels for centuries?
Were the Roman’s just sitting on magic batteries but did nothing with them because no one had invented the iPhone yet?
Nope. Sails. They work great for moving people and cargo across oceans.
No fossil fuels required
Ah yes, because in a conversation about better fuels for air travel, naturally I was supposed to think of sail boats.
Planes only make sense when you need to cross an ocean.
When you think of sustainably crossing oceans, you should absolutely think of sail boats.
Sail boats are a bag of shit
Sail boats are amazing. Wtf. Have you never been in one?
Yes I have been, they are wildly impractical for real international travel
Apparently you don't know history.
That's a stupid argument, sail boats are not practical in the world we live in today. Their use in the past doesn't matter, because that world no longer exists.
Absurd amounts of material and food are moved quickly and safely by modern shipping , sail boats are not capable of this.
If sail boats were practical then somebody would be using them already.
Enjoy your block bot
No.
