It's difficult to explain without diagrams.\n\nFirst you have an air supply at about 20 psi that flows through a restrictor and a small nozzle the same size as the restrictor. There is a flapper, a small piece of metal that covers the nozzle and controls the backpressure between the nozzle and the restrictor. The pressure between the restrictor and the nozzle is controlled between 20 and 100KPa (3 to 15psi) by the position of the flapper. The position of the flapper is controlled by the input current (usuall y 4 to 20mA of 1 to 5V). Thus the input signal varies the pressure out. I havent seen any links but I will look

Well, just like they fight fire with fire, you can fight static electricity with static electricity! \n\nWhat you must do is go out and buy a one hundred megavolt Van de Graff generator and bring it home and plug it in. You fire that sucker up and place one hand on the metal sphere and with the other hand, hold on to a metal stair railing or something. Let the machine run for about 15 minutes and get that juice flowing through your body! You may notice your hair standing on end, but don't worry, that's just a normal effect. After 15 minutes, turn the generator off and let go, but continue to hold onto the metal post. All that static electricity will zip out of your body and into that railing so fast, you'll also be free of static clink! \n\nGood luck and have a bright day and have fun with electricity! After all, it does make all our light bulbs work!!\n\nIf you can't afford a van de graff generator, YOU MIGHT WANT TO TRY AND INCREASE THE HUMIDITY LEVEL IN YOUR HOME ENVIRONMENT (ie PLACE OPEN CONTAINERS OF WATER ON OR NEAR ROOM HEAT SOURCES) SINCE IT DOES SEEM STATIC ELECTRICITY IS MORE PREVALENT IN DRIER CLIMATES.

If you think on the lines of the principle of using your bicycle to make the light work which is attached to the back wheel...then how about if you attach a paddle to the the dynamo place it in the house roof drain pipe. In theory when it rained the force of the water running down the drain pipe would generate enough energy to turn the dynamo.\nHence you have solved how to make current with a dynamo at home....brilliant!!!!!!

Not the easiest thing to explain via email but the best way to start is to understand clearly the function of the symbols shown in diagram. Once you understand what each item does find a starting point - usually the power supply and walk through it. ANother way is to get the corresponding termination diagram. I find them much easier to understand.

WOW!!!\n\nI have NO idea how it's done but it sure works ---- unless everyone chooses the same card??? I can't see how that could happen tho - thanks for the link :-)

Try it yourself, its not that bad. \nHere is how:\n1) Set up a stoichometry ratio.\n2) Using the mass that they give you, calculate the theoretical yield of each product.\n3) Whichever product has a smaller theoretical yield, analyze the reactants which caused it to be such.\n4) The one that 'limits' the amount of products is the limiting reagent.\n5) Using that value, calcuate the amount of the other reactant that is necessary. Subtract from the orginal value to find the excess reactant.

Well this isn't always easy to figure out and what I do is track the flow backwards till I hit the nearest data store then watch some data as it flows from the data store to each process checking the inputs and outputs. Your miracle is going to be the process which is taking no input but producing output.\n\nThis is what your data flow diagram is going to show you, where the miracle is occurring. You may need to go up one level to a more generalized overview of the system and find the component which is outputting without inputting. \n\nAnother way is by outputting some debug data before and after each process and comparing it to known data to see if it is working correctly. If you see an output message appear without the input message, then you found your miracle.\n\nStart with the general area you think the miracle is coming out of and watch data as it flows through it. That is the best I can tell you without actually seeing your DFD. \n\nHope it helps you out! Good luck!

How it works\nThe Van de Graaff generator is powered by a high speed electric motor. It has a belt running on two pulleys. The lower pulley is made of an insulating material and the upper pulley is made of metal. There is a grounded comb close to the belt in front of the lower pulley, and another inside the terminal, close to the belt in front of the upper pulley, connected to the terminal.\n\nAdhesion between the belt and the lower pulley charges the pulley, and it attracts opposite charges to the outer surface of the belt from the grounded comb. The belt then transports these charges to the terminal, where they are collected by the upper comb and transferred to the terminal. The shielding provided by the terminal allows the continuation of the process even if the terminal is already strongly charged. The high speed of the belt, along with the large discharge electrode, allows the continuous buildup of charges and great voltages to be achieved.

My God, I've never seen so much misinformation and confusion in my life.\n\nThe word "generator" is a generic name for a rotating machine which converts mechanical energy into electrical energy.\n\nThere are two types.\n\nOne type of generator is a dynamo, which produces d.c.\n\nThe other type of generator is an alternator, which produces a.c.

Are you referring to the Swiss perpetual motion machine?\n\nIf so, probably because no one has been able to duplicate the results at this point.

basically, you generate a list of random numbers (more about random number generation below), then use those numbers to calculate some output function.\nThen, you can have an "empirical distribution" about your output function.\nExample:\nyou can compute the present value of a financial project, GIVEN the values of, say, interest rates , sales level and inflation.\nYou also know that these three variables distribute normally and are correlated.\nThen you can generate a random scenario (one set os observations for each variable) and compute present value for it. You repeat the process a lot of times.\nSince you have a PV for each scenario you can observe its probability distribution.\nThat's it about Montecarlo Simulation.\nAbout Random number generation:\nif you know its cummulative probability distribution function (F(X)), then you can generate uniformly distributed random number in then (0,1) interval; let that be P.\nThe F-1(P) distributes with PDF F,where F-1 is teh inverse function of the cummulative function.\nThis method can be easily expanded to multivariate simulation using independt uniform variables, and the cholesky decomposition of the covariance matrix.\nNow, a note of care:\n\nMontecarlo methods can give the sensation that you can observe the distribution of a variable even if you know nothing about it. But, at the end, it's nothing more than a METHOD for computing PDF's  that are not easily expressed as functions.\n\nFinally, a note about computer power.\nMontecarlo methods are power hungry.Thus, using them to simulate PDF's of variables can indeed be expressed analytically is a complete waste of computin power and human time.

!WARNING!\nFirst before I even answer your question.  I just like to warn you that if your actually attempting a stunt like this be very careful.  Connecting 100 AA Batteries(1.25V) in series will produce 125 Volts.  Be very careful with it!\n\nAnswer:\nThe SI units of the electric field are volts per meter.\nThe equation for an electric field is: (E=V/r)\nWhere E=Electric Field, V=Voltage, r=distance from point.\nSo a higher electric field means two things: Higher voltage, or less distance. In order for you to get the highest voltage connect the batteries in series as follows:\n\nConnection: \nYou would need to connect the battery in series as follows to get the highest voltage. \n Bat1  Bat2  Bat3  Bat4  Bat5  Bat6      Bat100\n[- +]o[- +]o[- +]o[- +]o[- +]o[- +]o....[- +]o\n\n\nWhy:\nThe electric field is dependent on the voltage and distance. Increasing voltage will directly increase the electric field.  Decreasing distance will increase the electric field. Look at the equation above. E=V/r\n\nAnother way to think of it:\nThink of Voltage as pressure. And a ball as an point charge(electron).  Suppose you have a water hose and a ball.  You have to use the water hose to move the ball around.  If your too far away from the ball, the water will not reach the ball and the ball won't move.  The same thing happens in electric field.  The electric field is too far from the electron to make it move.  Now suppose you increase the pressure on the water hose.  Because of the increased pressure(Voltage) the water will shoot further and hit the ball, thus moving it.  If your very close to the ball you can use the water pressure(Voltage) to move the ball faster.

Show a floating ring gear assembly and ask how clean free energy can be produced from it. If you are smart and belive in God and Jesus, you will be allowed to see how it works. It has taken me over thirty years to see the final answer, but it was worth the pursuit. Upon seeing and understanding how it works, the rush is on as to who first presents it to the rest of the world in a working model. May you be a person of God and Jesus and then you will see how it is built. Trust me, it can be done. Dave.
