  • Chinese firm claims its hydrogen-powered car can travel 500km

    Well, so far it main cargo appears to be it's own fuel, but maybe more will come from this:

    Just add H²0 to go? Chinese firm claims its hydrogen-powered car can travel 500km fuelled by water

    • Vehicle has yet to be seen in public but local media reports it made its maiden journey last week
    • Chemical reaction of water and aluminium powder creates hydrogen to power the car, according to chief executive

    Wasn't the Hindenburg also filled with the same element?

      In the book Skunkworks by Ben R Rich he has a chapter on how they almost blew Burbank off the map playing with Hydrogen. Its a really good read. https://www.amazon.com/Skunk-Works-P.../dp/B00A2DIW3C

          And Challenger iirc

          Joking aside - it's almost inevitable that hydrogen or derivates thereof will be the main fuel in the foreseeable future.

            The problem is though, manufacturing hydrogen is a very "filthy" process for the environment. And 96% of the world's hydrocarbons is used to make hydrogen, which means we are using a superior form of energy to make an inferior one. The amount of carbon dioxide emitted from the processing side is ridiculously high to ever call it a green alternative for the combustion engine.

              Well the article I linked there doesn't call it "Green", just "rerenewable alternatives to fossil fuels" which is not quite the same…..

              If you can make hydrogen (literally "from air") using nothing but solar energy, and be left with nothing but water, and then use the hydrogen as fuel when lacking sunshine…

              you have a circular system no ?

              https://nieuws.kuleuven.be/en/conten...y-hydrogen-gas

              Bioscience engineers at KU Leuven have created a hydrogen panel that produces hydrogen gas from moisture in the air. After ten years of development, the panel can now produce 250 litres per day – a world record, according to the researchers. Twenty of these panels could provide electricity and heat for one family for an entire winter.
              Obviously efficiency needs to be further improved, but that's actually what scientists do best..

                Yes, you'd need solar(and huge amounts of it) to truly call it a better system. Because the energy required to seperate the elements is always as great as the useful energy produced at the other end.
                I'd be glad it something like the OP was true but my spider senses are tingling. Besides, the claim of the test vehicle doing 300 to 500 kilometres powered by 300-400 litres of water isn't exactly very efficient when compared to fuels we use now. It suggests to me that an enormous amount of energy is required to produce the hydrogen... thus a vehicle requiring more energy to produce less efficient energy.
                Electric cars are becoming more efficient, and are gradually improving with advances in battery tech.

                  That seems to be the case yes.

                  When I say "the foreseeable future", I'm thinking the next few centuries or so, not the next few decades

                  Still increasing efficiency of an existing system is what scientists are very good at..

                      The claim to have produced a car that will run on water with a special additive has been made at intervals since the 1930s - somehow the secret still escapes us. I suspect that this much the same

                      On the other hand hydrogen furled buses are already in service in various cities but they do not generate their own hydrogen but have a tank that has to be filled. There are some vehicles that generate gas for fuel but these are methane powered and have a digester that converts animal (or even human) waste into gas. The residue can be used for fertilizer

                        And where, we ask ourselves, is all of this aluminum to come from? How much additional fossil fuel usage to mine it, refine it and ship it?

                        Smelting aluminum requires enormous amounts of electricity. How much coal to produce that?

                        Powdered aluminum, BTW, is a main ingredient of thermite.

                          Hydrogen doesn't burn - it explodes.

                            Same thing, Gun powder and cordite only burn if not contained as in a barrel or a cartridge and hydrogen only explodes if you get a good mix with oxygen. There is the experiment that millions of school kids will remember. You get a gas jar full of hydrogen, slide the lid off and put a lighted spill in - the spill goes out. Repeat the experiment but leave the lid off for a few seconds before putting the spill in -whoomth. This is why WW1 fighters at first found shooting Zeppelins down difficult - even if they were using explosive or incendiary rounds. The incendiaries went out in he middle of the huge gas cells. It wasn't until they mixed the load up so that the gas cells were disrupted and allowed the hydrogen to leak out and mix with air and then it burned not exploded. The Hindenburg didn't explode - it burned - look at the news reels. That's why there were survivors. Explosion is merely very rapid burning producing lots of gas or vapour very quickly- quite different from detonation.

                              Fuel cells are twice as efficient as a hydrogen powered car, batteries are the way to go.
