attempted to build several hydrogen generators and none seemed to proform well,,why?

Because the bonds between the atoms are very strong, it takes a lot of energy to break them.

...And by "Hydro" you mean water? or Hydrogen?\n\nWhat type of power output do you need/want?\nHow much are you willing to spend?

I know that one thing they're using them for is car engines, although that's still in it's early phase.  Please to note, though, you left out the fact that extracting hydrogen from it's chemical friends is, as of yet, not energy efficient.  This is the main downfall of hydrogen fuel cells.  Currently, though, photoenzymes are being developed to solve this problem.  Until then, though, fuel cells are not a good alternative energy source.

Hey Bob,\n\nApparently, Yes, it can be done.  it can be a lot easier than you might think as well.  If you hold a flow of hydrogen to the carburettor, the hydrogen will be drawn into the chambers and combust, powering the engine.  There are a couple of major problems with this though.  First, you need a source of hydrogen, which means driving around in an H bomb effectively.  If you were to use water, and make hydrogen that way, the vehicle would have to be very very big to produce enough hydrogen to allow the combustion to work, so even though it can be done in theory, it's not safe or is not feasible just yet.\nAs soon as someone works out how to get the hydrogen from water more efficiently, they will probably be the new Einstein (or shot by oil tyrants)

e-mail me: intel_knight-at-yahoo-dot-com\n\nAnd I have no clue how to build that EMP thing, or if it is even possible. I just thought it would be a cool thing to have.

Start with the Ca then balance the number of PO4 ions, then balance the Oxygen and the hydrogens should balance themselves out.  Its just trial and error. Monkey with it until it works.

Get a glowing splint (piece of wood that is still burning out). \n\nPlace near the oxygen and it will glow brighter as it uses the oxygen to burn more.\n\nPlace near the hydrogen and you will hear a 'pop' sound. \n\nHope that helps! :)

Making a domestic bio-gas is not a big problem and failure chances are less if you operate or maintain it well. I would recommend to check web pages of any Madrass based firm or kerala. lemme find a web page for you and will b back soon,

One word of caution! The generators must be in phase for you to connect them in series and that will be nearly impossible to find in a small, commercial generator.  Without very tight control over each generators sync with the other, you could end up with anything from approx. double one generators voltage to the voltage of one generator alone and most likely fluctuating in between.  This will reek havoc on many things you may want to run with it and destroy lots of others outright. It could be done with the right electronics, engine and generator modifications and know how, but it would also be very expensive and time consuming.  If you need a 480V genny, it's much easier to find a used industrial engine welder or scavange one for its transformer.

Depends on what you mean by "new". There are lots of new sources in development, but nothing that is practical or economical yet. Hydrogen fuel cells are clean, efficient and non-polluting. But they are still very expensive and you still need a source of elemental hydrogen to make them work. \n\nOur best bet is hydrogen fusion - thais is what powers the sun. But we are still decades away from a successful commercial power plant. Until then, we are dependant on oil and natural gas.

I had this problem.  I had to make sure it was getting plenty of ventilation by moving it UP off the flat surface.  I have a Dell now....can't beat a Dell!!!  Try building some type of "stilts" only about an inch to set on, so it won't be setting flat on the surface.  It needs AIR.

fuel cell technology provides huge energy.....that's why they use it in power plants and space crafts....now Mercedes have their technology to reduce this power and use it in "Buses" and they were succeed to do that in 1998.  Now they are trying to implement this tech. in small cars. but they are facing some difficulties in using Hydrogen because it is very dangerous element.....they are trying to solve this issue by using some bi-products of the Hydrogen...as a result of that ...the efficiency will be less.\nso the limitations are :\n*the Huge energy that will be produced should be compatable with the engine been used.\n**using suitable Hidrogen bi-products for safety issues.\nI hope that I answered your question .....please try to answer mine.....\nRegards,\nFouad

Yes, we've known about electrolysis for a long time.  It's how submarines make breathable air while submerged -- they electrolyze seawater and just bubble the hydrogen overboard while releasing oxygen gas into the boat.  However, it takes a lot of energy to convert water into hydrogen and oxygen, which isn't a concern in a small space with a nuclear reactor to power everything, but it isn't a 100% efficient conversion of electrical energy into chemical potential energy.  There is a loss of energy due to heat, for instance (the electrodes heat up with current passing through them, and even the wiring that carries it there), and as with any energy system, you have to take entropy into account.  Depending on who you talk to, you can get anywhere from 50% up to 94% efficiency, but you'll always put more energy into it than you get out of burning the hydrogen later on down the line.  The reason we're still researching fuel cell and hydrogen cars comes from the mechanical efficiency of the different types of engines -- you currently still get more bang for your buck out of fuels than from an electric motor-driven car.  The energy is only reusable if burning the hydrogen generates the electricity to separate the water back into hydrogen again, in which case, you're talking about a perpetual motion system, and that's physically impossible.

Are the actuators getting fire?  Maybe you can spray a little WD 40 on the pistons.  Check your leads for corrosion.

There are many ways to generate hydrogen outside electrolysis. Steam reforming, methane reforming, propane reforming, etc... Coastal countries may appear to have an advantage but you cannot have a fair comparison of supply and demand.  Consider the following:\n1. Many, many, many countries have access to coastal water, thus competition would be extremely fierce\n2. Countries will be more than self-sufficient and may "sell" excess product at a very low cost.\n3. Rivers, streams, rainwater etc... is available to more countries in the world than petroleum to many. \n \nI would not worry about it, depleting the sea is way way way way off, and besides, using H2 as fuel means that emission is....water. And no, the roads are not going to be slippery from algae (sorry, but I have heard a statement like that in the past)\n\nEver considered that we may come up with the technology to recover and re-use the water emission? Thus less filling up at your local Shell H2 station? \n\nI hope I was able to answer it for you in a objective manner

General Motors is currently researching a Hydrogen Cell Vechicle.  If successful this vehicle would run on H2O.  The have a video on the research.  I wish i had the cash to buy stock in the company making the motor/cell.

Most small fans use shaded pole motors (see the link) and likely would not serve well as generators.  Also it would take a gale wind to rotate the fan nearly as fast as the motor can.  I have seen a vertically mounted 55 Gallon drum, cut to make wind vanes, that was used at a windy river location to drive a car generator.  Good luck!
