    Generating hydrogen for a 36m³ tethered balloon with HCl and aluminium

    I was referring to the oxygen released if H2O was involved. I'm going to purchase some aluminium powder and give this a go tomorrow. (Stupid Quastion) Is it possible to dehydate AlCl(H20)6 then recombine with stream? At what tempreture/pressure? Does anyone know of a more efficient (read...

    Generating hydrogen for a 36m³ tethered balloon with HCl and aluminium

    Are you sure none of the water in the HCl solution is converted? My understanding is that the aluminium chloride reacts with water to produce HCl and aluminium oxides, is this not correct? This is what I'm unsure about, that the aluminium is just a catalyst in the first part of the...

    Generating hydrogen for a 36m³ tethered balloon with HCl and aluminium

    I'm in Australia. I have several quotes from our major gas suppliers, and USD$1800 (AUD$2200) is the best I could get, including cylinder rental. I need the system to be portable, so that really rules out electrolysis. (Also, seperating the O2 is also an issue, as well as the time it takes)...

    Generating hydrogen for a 36m³ tethered balloon with HCl and aluminium

    Hi All, I am currently designing a tethered balloon. The balloon is 36m3 and I was hoping to fill with hydrogen. The balloon will only be fully inflated at 400ft as I am aware of the risk of a hydrogen explosion. Unfortunately I live in Australia and 36m3 of hydrogen is USD$1800! I am...
