<i>Until we have electric airplanes</i><p>While I believe battery-powered cars like the Tesla S make more sense than hydrogen&#x2F;fuel-cell based cars, perhaps fuel cells make sense in airplanes. For cars, the weight of batteries are an advantage as they provide down-force and can be readily charged by virtue of being close the ground where there&#x27;s infrastructure, in stark contrast to flying at 36,000ft where infrastructure is non-existent.<p>Addendum: The infrastructure issues that come with fuel-cell distribution and refueling would be eliminated thanks to the centralized nature of airports.
