    written: 2 H2O + Electric current => 2 H2 + O2 Now we know that it is: 2 H2O + Electric current => H + H + H + H + O + O => 2 H2 + O2 The middle step


    Hydroxy (hydrogen and oxygen) :
    Stan Meyer used a signal generator, rewired alternator, and a tube style electrolysis cell to run his Dune Buggy on water. He had numerous patents in the US and Internationally I've read most of Stanley Meyers patents and although I don't agree with his interpretation of the chemistry, he's inventions works.
    We also have the ambition to run cars on water, but it is very difficult. The main reason is that the gas demand varies a lot depending on the driver and driving conditions. To get a car to idle on pure hydroxy gas is easy and also to keep steady highway speed. The challenge is when the driver is climbing a steep hill or in city traffic. To cover both extremes; low gas production when idling at a red light and then huge gas production when the light turns green, we have to develop the hydroxy generator further. We are confident that we will succeed but it will take time. Right now we have an electrolyzer in production that will be five times more efficient than the car electrolyzer we have now. I doubt that it will be sufficient to run my Jeep Grand Cherokee, but time will tell. If not, we'll ad electronics to boost the hydrogen production and also get more hydrogen atoms. That should definitely be enough. Meanwhile, I use the electrolyzer to reduce my fuel bills significantly and at the same time releasing almost no harmfull emissions.
    The pictures below show water burning. The hydroxy gas comes from our electrolyzer. Note the red color of the flame. That's typical for hydrogen.
    Here are three favorite videos that show that it is doable. Click on the video you wish to view below.
    Especially "XOGEN" and "Danny Klein" shows the hydroxy gas that our car electrolyzer produce.
    Look at those videos and it will be a lot easier to understand.
    Danny Klein says he has patent on the method, which is NOT true or at least the patent is not valid, because there has to be something unique about it to get a patent. This is simple electrolyses and the gas HHO, is nothing new. It is just lately that more thorough studies of it began though. Earlier the electrolyses process was written: 2 H2O + Electric current => 2 H2 + O2 Now we know that it is: 2 H2O + Electric current => H + H + H + H + O + O => 2 H2 + O2 The middle step is very important because it is in that form the gas is used. The single atom hydrogen does not react like normal molecular hydrogen. It is just as powerfull in single atom stage as two hydrogen atoms in a molecule are. It also has other unique properties which we are just beginning to discover.
    During our experiments, we've found that the hydroxy gas has variable energy value ! When the flame is put close to a brick stone the temperature rise to over 4.000 Centigrade. When burning in air, like in the pictures above the flame has a temperature of app 300o C. Based on this we are getting some steel tubes built in brick stones to be used as heaters. We'll see how that works.
    To install the electrolyzer in a car is very easy as you can see:

    room condition, but this is an every day driver.

    Pin connections


    You can use the 555 effectively
    without understanding the function
    of each pin in detail.
    The 555 timer is an extremely versatile integrated circuit which can be used to build lots of different circuits.
    Up
    .
    Astable circuits


    Astable circuits produce pulses. The circuit most people use to make a 555 astable looks like this:

    As you can see, the frequency, or repetition rate, of the output pulses is determined by the values of two resistors, R1 and R2 and by the timing capacitor, C.
    The design formula for the frequency of the pulses is:
    The HIGH and LOW times of each pulse can be calculated from:

    The duty cycle of the waveform, usually expressed as a percentage, is given by:
    An alternative measurement of HIGH and LOW times is the mark space ratio:
    Before calculating a frequency, you should know that it is usual to make R1=1 kW because this helps to give the output pulses a duty cycle close to 50%, that is, the HIGH and LOW times of the pulses are approximately equal.
    Remember that design formulae work in fundamental units. However, it is often more convenient to work with other combinations of units:
    resistance capacitance period frequency F s Hz µF s Hz µF ms kHz With R values in MW and C values in µF, the frequency will be in Hz. Alternatively, with R values in kW and C values in µF, frequencies will be in kHz.
    Suppose you want to design a circuit to produce a frequency of approximately 1 kHz for an alarm application. What values of R1, R2 and C should you use?
    R1 should be 1kW, as already explained. This leaves you with the task of selecting values for R2 and C. The best thing to do is to rearrange the design formula so that the R values are on the right hand side:
    Now substitute for R1 and f :

    You are using R values in kW and f values in kHz, so C values will be in µF.
    To make further progress, you must choose a value for C. At the same time, it is important to remember that practical values for R2 are between 1 kW and 1MW. Suppose you choose C = 10 nF = 0.01 µF:

    that is:

    and:

    This is within the range of practical values and you can choose values from the E12 range of 68 kW or 82 kW. (The E12 range tells you which values of resistor are manufactured and easily available from suppliers.)
    A test circuit can be set up on prototype board, as follows:

    With the values of R1, R2 and C shown, the LED should flash at around 10 Hz.
    What happens if you replace R2 with an LDR or a thermistor? This gives an astable which changes frequency in response to light intensity, or with temperature.
    Up
    .
    Astable component selection


    With a little practice, it is quite easy to choose appropriate values for a 555 timer astable. To make things even easier, you might like to download the DOCTRONICS 555 timer component selection program.
    The program works with Windows 95 and looks like this:

    Up
    .
    More astables


    Extended duty cycle astable:
    An extremely useful variation of the standard astable circuit involves adding a diode in parallel with R2:

    This simple addition has a dramatic effect on the behaviour of the circuit. The timing capacitor, C, is now filled only through R1 and emptied only through R2.
    The design equation for the output pulse frequency is:
    HIGH and LOW times are calculated from:

    With this circuit, the duty cycle can be any value you want. If R1 > R2, the duty cycle will be greater than 50% (*****alent to a mark space ratio of more than 1.0). On the other hand, if R2 > R1, the duty cycle will be less than 50% (mark space ratio less than 1.0).
    This version of the 555 astable is used in the cyclist/pedestrian safety lights project.
    Up
    Minimum component astable:
    This is a cheap and cheerful astable using just one resistor and one capacitor as the timing components:

    Note that there is no connection to pin 7 and that R1 is linked to the output, pin 3.
    The design equation for the circuit is:
    The HIGH and LOW times are supposed to be equal, giving a duty cycle of 50% (*****alent to a mark space ratio of 1.0).
    However, if you build this circuit, it is probable that the HIGH time will be longer than the LOW time. (This happens because the maximum voltage reached by the output pulses is less than the power supply voltage.) Things will get worse if the output current increases.
    If you need an astable circuit which can be adjusted to give an accurate frequency, this circuit is not the one to choose.
    Up
    Diminishing frequency astable:
    The excitement and realism of electronic games, including roulette, can be increased using an astable circuit which is triggered to produce rapid pulses initially, but which then slows down and eventually stops altogether.
    It is easy to modify the basic 555 astable circuit to produce this result:

    When the 'go' button is pressed, the 47 µF capacitor in parallel with the timing network, R1, R2 and C, charges up very quickly through the 100 W resistor. When the button is released, the astable continues to oscillate but the charge stored slowly leaks away, with the result that it takes longer and longer to charge up the timing capacitor. To trigger the next pulse, the voltage across C must increase to two thirds of the power supply voltage. After a while, the voltage across the 47 µF drops below this value and the pulses stop.
    With the values shown, the initial frequency is about 100 Hz and the output pulses coast to a stop after around 40 seconds.
    The initial frequency can be calculated from the design equation for the basic 555 astable. To give a realistic coasting time, you should use large values for the resistors R1 and R2. The coasting time is determined by the 47 µF capacitor. Experiment with different values until you get the effect you want.
