    Apr 24 2012: I understand about the storage issues...but wouldn't it make more sense to really have it self-contained outside? I'd feel safer that way.....like what we currently use for the 500gal tanks of propane gas used for heating....... ?? I wish I could find the dvd that I had watched that showed the new scientists that were working on low pressure storage tank systems and battery fillings that were organic!!! It was soooooo interesting and it's what started me thinking along the lines of personal home use! If I find it I'll post it here. :)

    Apr 22 2012: What is this used for??? Isn't this a power source generator? and..........wouldn't the 'idea' of it work for home use?

    Apr 22 2012: Here is the link for Shell's hydro station that is on site....this is what I was wondering too...why cant this working idea be addapted for a personal home use? I know, I'm out there....but, if we already know how to produce hydrogen power.......seems to me that the logical end would be to power our homes from it too. Electric/hydrogen and wind/solar should, in my opinion, all be utilized to personally power our homes and transportation......but then again I'm thinking more like rural homes not city.....but building a larger on demand site for city users........well why not??? ;) I truly believe that as humans go......we can solve any issue if we work together and let the creative muses out to do what they do best - create! :D

    Apr 22 2012: Here is a snipping from one of the articles I've read....they are looking at several ways to store the hydrogen. I can't remember which documentary I was watching that showed Hydrogen Generators already in use at what I thought, was Googles Headquarters...but for the life of me I can't remember who the company was that produced it. When I find it I will post it here.

    "Electrolysis is a process that is most common for hydrogen production. Hydrogen generators produce
    hydrogen at a flow rate that is not sufficient enough for direct compressor use. A buffer container is used for
    collecting enough volume of hydrogen from the generator for the compressor. Since hydrogen coming out of
    hydrogen generators is
    of low pressure, the
    buffer becomes bulky.
    Both hydrogen
    generator and hydrogen
    compressor are heavy
    users of electricity;
    besides, fuel cells are
    fragile for hydrogen
    supply of unstable
    pressure and low purity
    of hydrogen.
    Metal Hydride (MH) is the answer for the given dilemma. Compared to high pressure tanks, metal
    hydride storages require less pressure and compression. Its volumetric density is no larger than that of high
    pressure tanks. The current development of metal hydride technology has reached point that for same
    capacity of hydrogen content, metal hydride storages are no heavier in weight, but 15 times smaller in volume
    than 150bar high pressure tanks. Charged with lower purity hydrogen gas, metal hydrides purify the stored
    gas instantly, and deliver higher purity gas at no additional cost. For the benefit of fuel cells, metal hydrides
    deliver high purity, stable pressure hydrogen at constant flow rate, which considerably prolongs equipment
    lifespan. "

    Apr 4 2012: The H2 generators that I had seen on a Science show....was working on a bioengineered storage cell that would allow the Hydrogen to be stored without pressure (like current gas tanks) and that would make it safer... The generators I was thinking about would be an outside system that would operate like current backup emergency generators.......but would run on Hydrogen instead of gasoline. ??? I don't know, I was just thinking that with all the people on this planet - we should be able to get a group of like minded people together that can come up with a more cost effective way to power our homes.
