    Gonna take this as ironical coz it's posted in /c/memes , but I see some comments aren't getting it so I'll mansplain:

    Hydrogen is an energy storage mechanism, not a source of energy. You can use energy to split the h2o in water into hydrogen and oxygen, and use that hydrogen to run a car, but the energy had to come from somewhere. The hydrogen serves the role of a battery; a car that runs on a battery is powered by the energy it gets from the charger, not by the battery itself.

      Plants use energy from the sun to split H+ ions and O2, maybe he invented a photosynthesis car?

        Broke: fossil fuels

        Woke: plant fuels

        Bespoke: plant cars

        Baroque: fossil cars

          They're really good at running on sunshine and very bad at all the things you would want a car to do.

          I mean, you don't really want a solar powered car. You want a battery powered car that's charged with solar energy collected on a prior day.

          That said, vehicles like the Sunswift lay the groundwork for efficient transfer of solar energy into mechanical energy. And there's definitely value in further researching this field of study for - say - building scale solar powered air conditioning or portable charge pads.

      That might be a little confusing - the hydrogen is no more a "battery" than diesel is a battery that stores the energy from the sun - like that's indeed what the molecule does but not really what people tend to think of when they think of a battery.

      Like it's probably simpler to explain that hydrogen is a fuel, but to make that fuel from water you had to put more energy into splitting the water than you get out of the burning of hydrogen as a fuel.

      Also hydrogen is explosive as fuck, so hydrogen-powered cars spook me out.
