Nah, not very fine. I wonder if it could be less eco-friendly to run something like this over an ICE car simply due to the massive energy demands of such a vehicle and the losses on energy to hydrogen to energy conversion.
Flying transportation is only reasonable at a large scale and high speeds, which is not a characteristic of an air taxi.
Also, better use hydrogen-powered car then.
While hydrogen is expensive to produce, it can be produced from reusable sources or surplus energy which makes it way cheaper and way cleaner. Also solves energy storage. A side note: ICE is around 20% efficient. I’m also sure that flying in choppers and private jets is not that clean and efficient. And yes, cars would be better, but both can coexist.
True, but that would require building expensive infrastructure that would sit idle for most of the time while we wait for the surplus - assuming we talk intermittent renewables.
Sure enough, hydrogen fuel cell is cleaner than ICE, my objection was to the form of transportation that might require so much power an ICE car would be a better alternative (but not an ICE air taxi, to be clear)
From an ecological perspective, they can not, and that’s what this “invention” pretends to be about. Also, cars too are far from perfect, but at least better than this monstrosity
