      It is a nightmare fuel, even for NASA, and is absolutely not suitable as a general purpose transport fuel.

      Fun facts to know and tell.

      High purity hydrogen is used to fill the generator casings of steam turbo generators.

      The low viscosity significantly reduces drag on the rotor and the high thermal conductivity extracts heat more efficiently than other gasses. Maintaining gas tight seals is a mission, however.

      That’s about as near to electricity generation as you’d want hydrogen.

    Good article about some of the difficult issues with using hydrogen as a fuel.
    He does not mention that hydrogen causes embrittlement of most materials which makes it even more difficult to store it under pressure.

      The fact that the practical realities of hydrogen use such as hydrogen embrittlement of metals (known about since 1875), problems of sealing pipes, tanks and valves, an exceptionally wide explosive and flammability range, storage etc. are never mentioned by the wokesters and subsidy harvesters who promote this fuel shows you their utter ignorance of the relevant science and technology.

    So, I’m on a flight inbound to Australia (connected via onboard WiFi), and it was announced that someone was caught vaping in the toilet and upon landing they would be handed over to authorities and prosecuted.

    I am amazed that anyone would try smoking or vaping on an aircraft these days. Especially on flights under Australian jurisdiction where regulatory enforcement tends to be strict with heavy penalties (although laws relating to crime and violence are not strictly enforced as we can see in lawless Melbournistan).

    Wow of all the “Engineering degrees” that its possible to get, one can now become a “Climate Engineer”
    Once again the dreamers come up with ways to save the planet from its self.

    There is a new buzzterm.

    Renewable gas.

    It refers to biomethane and hydrogen.

    Renewable gas is a term used to describe gases produced from renewable or replenishable sources. These include biomethane and renewable hydrogen.
