Hydrogen power is the past not the future it's just a past that never came to be so we sort of feel like it's something futuristic.

It's a great idea in theory but there's so many problems with the idea not least of which is where do you get the hydrogen from? The amount of power that you would need to compress hydrogen into liquid on an industrial scale would practically necessitate dysonsphere.

    I think Toyota and Honda... maybe somebody else was developing a Hydrogen cell car. I remember seeing James May on Top Gear talking about it and driving it. It was in California. It seemed really promising and very exciting at the time that's why the memory imprinted on me a bit.

    Toyota at least was getting their hydrogen from natural gas which rather defeats the whole point really.

    In order for hydrogen power to be sustainable it has to come from electrolyzing water. But the power requirements are prohibitive since the process is unimaginably inefficient. Something insane like 80% of the power goes to waste when converting water into hydrogen and then you've got to find a way of compressing that hydrogen and transporting that hydrogen.

    I'm not saying it's impossible but in a world where you can recharge an electric car in 5 minutes what's the point in even going to the effort of solving those problems.
