    Two Car Speakers NEED MODDING!

    JaValon; Mad props to you... that kicks a$$.

    From an old car audio guy, you made my day.

    Here's mine (not as fancy) but its got a lighter... 6" DVC sub inside under the deck and 40x2 amp above it.

    BTW; see if you can find some 14-16 volt capacitors, large 500+ uF they will help your power supply so it won't clip

    I would think that leakage and possibly trace minerals will be an issue. Nice system by the way. What do you figure the efficiency is?

    Thanks; and the big issue is that since hydrogen is the smallest molecule, over time it will seep through what ever the storage medium material is and make it brittle. even the most advanced materials will break down within a few years and start falling apart. So those fancy tanks you see used for storage will still breakdown after several years.The higher the pressure, the faster this will happen.

    As to the efficiency; we were mainly working on proof of concept. A couple items that the efficiency is tied to is the electrode material and the electrolysis solution, we used standard carbon steel electrodes and many different solutions (lye is the bomb, but major caustic, be careful) oh, then the end of a 25 year marriage canceled forward progress on it, for the time being...

    On 4th of July's we did have fun filling large clear garbage bags with hydrogen and attaching long fuses...

    Then letting them go up over town, the concussion when it blew was the best...

    This system still exists, sitting in my fathers barn right now.

    The generator is on the right in the picture and the storage on the left.

    The generator uses a "W" bin configuration, it also has dryers, filters and flow meters.

    Right now I am building a HHO gas generator for one of my motorcycles. 30 sec burst, then let battery charge.

    Should help the old 1980 kz750 twin do some street fighter gigs at the lights still ;)

    The 1994 CB1000 is getting a turbo next :)

    *Hydrogen is actually really interesting, you can use a form of electrolysis to generate it your self from water. So you could, in fact, use the solar panels/wind turbines to charge batteries then use all the excess they are generating that is not powering the racks to make hydrogen. Though this process is highly inefficient in terms of the energy used to make the hydrogen verse the amount of energy burning the hydrogen produces, but the energy in hydrogen can be stored far more compactly (compressed in canisters) than the energy stored in batteries.

    This is the Hydrogen system I built to heat a garage in northern Minnesota, it splits the Hydrogen and Oxygen and pumps each into separate tanks, then the Hydrogen was used through a propane heater. Cycled the generator between 20 to 60 psi, propane heat only needed 11 psi to work. Used solar to charge the battery about 20% of need, solar alone couldn't keep up with the demand of the generator. solar provided only 100 watts at peak. generator would use upward of 30 amps to run, oh and 30 amps would get the generator damn hot if ran too long (thats why we cycled it).

    Trivia; what part of the hydrogen use process is still a major issue/problem before public use? my system suffers too.

    Hint; even the new hydrogen cars suffer from this issue, it will cost you plenty to fix in a few years in those cars...

    Hint 2; Hydrogen is the smallest molecule...
