I drove 1800 miles in a Hydrogen Car

I'm an aerospace engineering major working currently as a mechanical engineer.  I find it awesome that you know so much about so many great things but find it daunting to learn about renewables.  lol  I'm waiting about a year after I graduate to order my Cybertruck and all my lawncare equipment and hand tools are not only electric but also 100% solar powered.  Most people don't know that running a lawn mower for 1 hour is the equivalent of running a modern car for 40 hours.  There are no emission standards for small engines.  I am not sold on hydrogen power because I prefer electric but I would like to see more on the road.  (Update:  I thought they still burned the hydrogen too!!!  Hydrogen conversions have historically burned the hydrogen!)
