    Ok, let me ask you this. What do you use to create Hydrogen?

    Electricity is not a limited resource, water makes it
    What the **** are you on about?

      I assumed he was speaking of hydroelectric dams.

        A fuel cell is an electrochemical device. There is no combustion at all. Spec has stated that this car has a rotary engine, which is an internal combustion engine.

        Something can't both be a fuel cell and a rotary engine. They're two incompatible terms.

          There isn't infinite ****ing hydro capacity. Certainly not infinite economically viable hydro capacity.

            I believe a fuel cell can be used to break off hydrogen forming hydrogen gas (instead of an electric current) and then the hydrogen can be combusted to power an engine.

              That must be a new generation of fuel cells because normally the point of a fuel cell is to use hydrogen gas and react it into water without th ebang in between. Using hydrogen in a combustion engine has bno advantage over this, nor is a device that produces hydrogen out of another substance called a fuel cell.

                I saved them and tried to attach but the images are to big. If I shrink them down enough to get uner 500k they get to small and we cant read anything.

                Far east canada is one of the places that increased the most.

                What you're looking at is a graph which related precipitation to potential evaporation. That is not a ****ing measurement of humidity in the air.

                  What are you talking about? A fuel cell is a device which transforms chemical energy (in a hydrogen fuel cell this is the heat of reaction of 2H2 + O2) directly to electrical energy.

                  I honestly have no idea where you're getting the idea that a fuel cell is a source for hydrogen gas. In fact, a hydrogen fuel cell uses up hydrogen gas and converts it into water.

                      Actually, it might. Converting the chemical energy directly into mechanical work may be more efficient than first generating electrical current and then running an electric motor.

                        Less so if you have to generate that chemical energy out of a hydrogen source first, using one of Oerdin's magic "fuel cells"

                          Well, yeah.

                          Then the question becomes "where did the energy come from"...

                            Let me think, I've once seen a model where the overall energy balance was positive as in even after cracking some methane or whatever the car could still run on the leftover energy. So all you'd need would an ignition of some sort and then the energy would stem from the fuel cell reaction.

                            Basic condition: the 2 H2 + O2 --> 2 H2O would have to generate a lot more energy than whatever reaction in use to produce the hydrogen. Might work for a lot of basic substances. The lower the energy requirement for this cracking process, the more power is leftover for whatever mechanic use behind it.

                            However I think most applications use hydrogen in a tank. Alternative: a hydrogen supply network/infrastructure to avoid storing. Hydrogen drains in households like with electricity. Small tanks in cars and lots of service points to refuel. Easier to imagine in big sites for industrial use.

                              If you put in methane or any other hydrocarbon then you're back to releasing CO2, dude...

                                Hydracine? IIRC that one was used on the Apollos. It's said to be carcinogenic though.
