Hydrogen vs. Battery Electric Cars

9:02 nice hydrogen powered boat.......but wait a min are those solar panels?? No, wait, those are glasses for style, noice..... But this gave me an idea, I watched one of the Linus tech tips video in which then converted a boat to modern boat(installing a tv, speakers and kinds of modern home things), in that video they also said that the solar panels could also run the boat, well that is very convenient if you ask me. Instead of refueling constantly (hydrogen or petroleum), wouldn't it be more convenient to refuel it while using it?? Ok, but the last part is actually good, energy diversification is important!
