introSeparate Hydrogen and Oxygen from Water Through ElectrolysisElectrolysis a method of separating elements by pushing an electric current through a compound. It is used in various industrial applications such as removing copper from its ore. It is also used to separate hydrogen and oxygen from water. Electrolysis isn't the most efficient way to obtain hydrogen, but it is one of the easiest and cheapest ways to "homebrew" hydrogen. 

Hydrogen is the most abundant element in the universe. With the "green-energy" craze and talk of powering our future oil-free economy on hydrogen, it has gotten much attention in the last few years. Learning about this potential fuel of the future is important and interesting. Besides, hydrogen is a powerful fuel, and blowing stuff up in the name of science is fun .

tep 1Electrolysis of Water - An ExplanationThis section is an explanation of the electrolysis of water, feel free to skip it if you don't find it interesting. 

2H2O(l) = 2H2(g) + O2(g)

As everyone knows a water molecule is formed by two elements: two positive Hydrogen ions and one negative Oxygen ion. The water molecule is held together by the electromagnetic attraction between these ions. When electricity is introduced to water through two electrodes, a cathode (negative) and an anode (positive), these ions are attracted to the opposite charged electrode. Therefore the positively charged hydrogen ions will collect on the cathode and the negatively charged oxygen will collect on the anode. 

When these ions come into contact with their respective electrodes they either gain or lose electrons depending on there ionic charge. (In this case the hydrogen gains electrons and the oxygen loses them) In doing so these ions balance their charges, and become real, electrically balanced, bona fide atoms (or in the case of the hydrogen, a molecule).

The reason this system isn't very efficient is because some of the electrical energy is converted into heat during the process. There have been reports of 50%-70% efficiency, but I doubt that is possible in a home environment. Anyway, enough with the boring stuff, lets go make some gas!

step 2Materials****DISCLAIMER**** You are putting electricity into water. It has the potential to be dangerous. Do so at your own risk. Be smart about it. If you wouldn't touch it with your hands don't stick it in the water. If you're worried about it wearing rubber gloves will give some extra insulation. ****DISCLAIMER****

****DISCLAIMER**** Hydrogen is highly flammable and explosive (think Hindenburg). The amount we're making isn't extremely dangerous, but be careful. Flying shards of glass are never fun.****DISCLAIMER****

Separating Hydrogen and oxygen from water is really simple. It can be as easy as sticking two wires leading from a battery into water and watching the bubbles form. We however want to collect all the little bubbles, so its just slightly more complicated.

Things you will need:

@ (1) Med.Container - To hold water. Preferably clear so you can see whats going on.@ (1 or 2) Gas Collecting Containers - A test tube, or an old soda bottle like me. Also clear. 2 if you want to collect both the hydrogen and the oxygen@ (1) Power Source - I use a 12v 1000mA adapter, 9v batteries (in a series) and other sources work too. Bigger the power source, faster the bubbles form. 

@ (2) Graphite Electrodes - Optional. You can stick a bare wire into the water, but it corrodes pretty quick. You can pull them out of a 6v Lantern Battery@ Salt@ Water 

step 3Water and SaltWater alone is not a very good conductor. You need to add some sort of electrolyte. Regular old table salt works fine. Add as much as will dissolve into the water, and don't worry about it if there is some sitting on the bottom, it really doesn't matter. Pour this salt/water solution into your med. container, and also fill your 1 or 2 gas collecting containers

step 4The Tricky PartOk, this is the tricky part. You need to flip the gas collecting container(s) upside down in the med. container, so that no air is trapped in the gas container(s). I do it by holding my thumb over the hole, and flip it really quickly. Its not a huge deal if air is trapped, your hydrogen just won't be pure. 

i

step 5The ElectrodesNow take the two electrodes leading from your power source. The hydrogen will form on the positive electrode, and the oxygen on the negative. If you don't know which is which, turn on the power source and stick the electrodes in the water. The one with more bubbles is the hydrogen. Now stick the electrode underneath the gas collecting container. (turn off the power first) If you're having trouble making the gas collecting container stay up, and the electrode stay in the right place, tape it. Thats what I do anyway. 

step 6Thats it!Thats it! Turn it on, and watch it bubble. The amount of time it takes depends on how powerful your power source is. Stronger it is, faster it bubbles. Mine takes about 5 min for a test tube.

The electrodes do corrode if you don't have graphite, its pretty gross, but i don't think its dangerous. (don't quote me) 

Here is a video of it bubbling:

introCollecting Hydrogen and OxygenIn this instructable I'll give you a simple way to collect Hydrogen gas and if you want also, to collect Oxygen. Depending on the voltage and current that you use for the project this could be hazardous. I used a 14.4 volt power drill battery pack for the process but don't recommend it, I only used it to achieve a noticeable effect in a short time period (about 20 minutes).

i

step 1MaterialsThe required materials are:

-Sufficient length of wire-DC power source-Deep water basin or bowl (preferably plastic, there is a chance you could ruin a metal one)-Water, logically-Weak acid (ex.vinegar as acetic acid)-At least two plastic bottles with caps (I like the Gatorade ones because they are thicker and for some reason the Hydrogen at least will compress itself after a few days)-A sacrificial pencil (or if you have lead [graphite] from an architect's pencil use that instead)-Small pencil lead case or even just the cap (the refill material case for mechanical pencils)-Tape-Putty-Marker to label the gases-Long piece of tubing if you cannot find a bowl deep enough-One sided blade or knife if you use a pencil

-You may also want other materials to plate or turn into Oxide salts

step 2The Non-Electric SetupFill your bowl most of the way with water, the purity of which doesn't make much difference so long as you don't use mud or something. Now add your salt or weak acid to the water, it doesn't take a large amount of either to get a good result so be moderate with it you can always add more later but can't take it out. Fill the two bottles as full as you can with tap water and carefully put it into the water so that the lip of the bottle is turned down, do this with the second bottle. Make about two or three fingers worth of room between the bottom of the bowl and the lip of the bottle and tape it to the side so that the tape is not underwater. If you were unable to get all the air out this is the point where you want to get out that tubing and put it in the bottle while still underwater and suck the air out but try not to get a mouthful of acid or saltwater in your mouth.

tep 3Electric SetupTake the pencil and shave off the wood so that all you have left is graphite, if it breaks wait to throw it way if it is long enough you may be fine. Then take two lengths of wire and strip the ends off for each wire wrap one end for both around a length of the graphite. Then take your pencil lead (graphite) case and push putty into it so that it is a solid mass and has no cracks. Take one of the wires and push the end with the graphite into it so that none of the metal of the wire is showing but the graphite is. Then secure the ends of the wires that do not have graphite to your DC sourceIMPORTANT-place the wire with the case on the positive (generally red) end of your source otherwise the unshielded wire will dissolve into an oxide salt

step 4Combined SetupNow you're ready to place your electrodes into the electrolyte (saltwater / dilute acid). Arrange the electrodes so that the bubbles are floating into the bottles. If you have no bubbles then you did something

wrong if you only have bubbles coming out of the negative side then you may be usingactual lead (unless you are intentionally oxidizing some other metal this is normal).

step 5Filling and ConatainmentNow all you have to do is wait for the bottles to become filled with the gas coming from the electrodes. When doing this the unshielded wire's bottle should be filling faster, about twice as fast because water is two parts Hydrogen and one part Oxygen (and because they are both part of the diatomic BrINClHOF [If you have not taken Chemistry disregard this statement it's not important]). If the unshielded wire is making less than the shielded one, turning blue or falls off then you may have switched the charges.

If / when they do fill take the bottle cap of that bottle and make a ring around the inside of the cap and place it underwater and screw it on without letting air out or in. Once you do this use your marker to label it the bottle with the unshielded wire is Hydrogen and the shielded one is Oxygen if you did this correctly.

step 6Extra PossibilitiesAlong with making Hydrogen and Oxygen there are other things you can do with this concept. One is Making Oxide salts (i.e. metal+Oxygen such as Fe2O3) although this will not allow you to collect gaseous Oxygen, you can make pigments out of this such as turquoise blue with Copper or Orange with Iron. You can also make Aluminum powder for thermite, with the positive being Aluminum and the negative being Carbon (Graphite/pencil lead) the Aluminum either does not bond or it decomposes. If I'm wrong it will stay bonded but can still be used as a pyrotechnic. You may also plate a metal using this with the plating metal on the positive and the object to be plated on the negative although this will also crate it's oxide. All you have to remember is that the

positive will dissolve into an oxide salt and the negative will be plated. Have fun experimenting

introHow to build a water assisted engine systemFriends,I have an Idea budding in my head to run engines on water as fuel.Today, I will share my thoughts with you and provide you a good clue of what could be the solution of GAS alternative.Friends, before starting with the instructable I want to make it clear that I haven't build anything with this idea as of now. So, I am not completely sure how far it is safe and possible.With this in mind lets start the 'project ENVIRONMENT'.....

I TAKE NO RESPONSIBILITY OF HARM CAUSED DUE TO THIS INSTRUCTABLE.

P.S.: Those who are looking for the prototype, this instructable will not help you.

I will like to thank all those whose instructables I have used here.

step 1 Basic Concept The concept is to generate hydrogen from water through electrolysis and use it to power the usual petrol engine. Electrolysis of water: Go to my instructable on 'HHO …

step 2 Supply hydrogen gas to engine Supply hydrogen generated from electrolysis to engine through the petrol intake valve. Petrol engine uses a mixture of petrol and air to fire. Instead of petrol we will …

step 3 Vary voltage of DC supply to control Electrolysis process THIS IS THE STEP WHERE I HAVE NO CLUE OF WHAT CAN BE USED TO VARY VOLTAGE. HOWEVER, I can help you of what can be done. Use a tachometer sensor (tachometer is used to r…

step 4 The DC supply DC supply powers the electrolysis process.... To charge the supply, use a battery or dynamo/alternator. Read the following instructable: http://www.instructables.c…

introHHO generatorHi frnds!

Here I am at my attempt to give you more information about powering engine using water.This instructable is a part of my previous one. Do visit that one to get a clear idea.

I am posting a video on how to build a HHO generator which will produce HHO gas to power your car's engine.The video has part 2 for details. It leads you to a site and wants you to buy the guide.

I am posting my version and giving you a detailed information on how to do it.

Let's start!

i

tep 1Things we needThings we need.

Parts:1. Glass jar with plastic lid2. Pet/squeeze bottle3. 1000mm long braided wire4. 500mm long water pipe5. 1000mm long electric wire6. CD case or thick plastic sheet7. 2 screws with nut8. Hollow screw with nut9. Cheap pen without refill10. Fuse

Tools:1. Drill machine with bits2. Screw driver set3. Saw4. Ruler5. Plase

step 2Setting the plastic lidRemove the lid from the jar and with the help of ruler mark the centre of the lid.Mark four holes for HHO gas, 2screws and fuse.Drill holes through the marked points and insert screws and fuse respectively.

Now, take the cheap pen and cut near the rear end and insert the piece in the HHO gas hole (watch the video).

Now, insert the water pipe at one of the pen. Connect the wires to the screws.

The lid is now ready.

step 3Making the wire mesh for electrolysisFor making wire mesh, take a plastic sheet and divide it from centre. Then cut into 2 pieces using a saw as shown below.Mark the center of each of 2 pieces and draw a line from the centre to one end. Cut using

saw as shown below.

Now, carefully drill holes and cut small grooves at the end of the piece and join them as shown below.

Use the braided wire and cut it into 2 and insert in each of the 2 holes of the plastic sheet. Cover the sheet with the wire as shown below and then connect the 2 ends of the wire to each screw respectively.It should look similar to figure shown below.

http://www.instructables.com/id/S8QMPLOFJ8OHYNN/

tep 4setting up the pet/squeeze bottleMake a hole and insert the pipe in the bottle. Make sure the pipe reaches to the bottom of the bottle.

Now, drill a second hole and insert the hollow screw there.This hole is for using the HHO gas. Fill the bottle with water and leave some space for air.

The Center one will pass the HHO gas through water and you will see bubbles coming out. The gas will than escape through the hollow screw which can then be used for combustion.

tep 5SummaryThe assembly is complete.

Fill some distilled water and 3-4 tea spoons of baking soda. Connect the electric wires to 6V to 12V battery to start the process. HHo gas is released from water. It travels through the pipe into the bottle releasing bubbles and escape from the hollow screw.

You can use this gas to run your vehicles engine.

MAKE SURE YOU HAVE SEALED ALL LEAKS.

I TAKE NO RESPONSIBILITY FOR ANY ACCIDENTS AND/OR CASUALTY CAUSED DURING TRYING THIS EXPERIMENT.

VISIT www.hho4cars.com to know more about the use of this gas. Pass on this instructable to all your friends and relatives and let them know the benefits of water.

Enjoy!

introHHO car adaptationHHO is the gas resulting from electrolysis of water. Two H's and an O when seperated are very flamable. On top of being abundant it is cheap and cleaner burning than gasoline. Operating on purley HHO requires lots of modifications to a car but suplementing your gasoline with HHO requires little. There are a million sites out there on HHO car conversion kits. All of them are building plans for anywhere between 50 to 500 dollars. It seems odd that there is no instructable on it. So here, for free, is my attempt at making one. The text at the top is my first try and the text under the "-" line is my second try.

step 5From container to carNow do the same for your plastic hosing as you did for the electrodes. Melt(or cut) a hole IN THE TOP and seal your hose into it. The hose needs to be long enough to reach the outlet coming from your air filter in your car. Melt(or cut) a hole in the hose leaving your air filter and seal in the hose coming from your HHO container. Ouch, I hated to do that step. Willful destruction of car parts. It helps a lot if you have an easily removable piece like I did.I wanted to mention it somewhere and I thought the inserting your electrodes step was already to long, wrap some teflon tape around the teeth that hold the cap on. This will cause LESS HHO to leak out the top. I don't think its possible to completly stop hydrogen from leaking out of a container while allowing easy access to pour more water in.The water you put in this container needs to have baking soda mixed in. I read that using salt will produce chlorine gas. That seems likley to me as salt is NA CL. Sodium and chloride on their own are deadly to you but combined they sure taste good. In other words don't use it.

-updates--I was going to use baking soda origianly but I later read that it lets out solutions that are corossive to aluminum. Chances are your car's engine is made out of it. Furthermore, the chlorine will be coming out of your tail pipe. Who breathes in car emissions that wants to live anyway? The chlorine released is small ammounts too.

.

step 4Inserting your electrodesI did this all wrong at first. I was cutting holes in the plastic with my knife. It is so much better to use a soddering iron to melt a hole in your grape juice bottle and then using a circular motion widden it it to fit your electrode. I had to seal over and over again on the knife cuts but the soddering holes sealed in one try.Now you ask where do I put these holes at? I placed my electrodes on opposite sides of the container. I was thinking that the further apart they were the more water the current would pass through and create more HHO. I later read that having them closer together is actually more preferable as the electricity is "burned up" in the resistance rather than actually doing work on seperating the molecules. Please post if you think you know how it really works.(update: not necessary. Put them very close together)However it works, it is very important to know that the electrodes are NOT continuous. That means they do not touch anywhere and they need to be secured so that while driving they do not run into each other. To secure my electrodes I soddered two holes next to it while it was in the container and fed some wire sheathing through to tie it down. It is likley this step will frustrate you unless you plan on big holes and more sealant. I would not recomend using any sort of metal(tie wire)because it will corrode inside the container. A tie wrap would probably be nice though.The wire and connector on the electrode need to be on the outside of the container. Then you can begin the sealing. Generously apply sealant to anywhere water may leakout. Let it dry for 24 hours(so says the tube) then fill it with water. If it leaks drain it and put more sealant where it was leaking.Advice from a big dummy: If your electrode is hollow like mine seal one or both ends. I will let you think why.(there's 24 hours wasted)

-updates--the graphite I used is much much smaller than the original electrodes but produces almost the same ammount of gas because they are so close. Holding the graphite down inside the container isn't as necessary because the tye wraps will always hold them a certain distance apart.

step 6Giving life to your monsterThis is going to be the scetchiest part of my instructable. I am still searching on a good way to power it only when the car is on without having to drill through the fire wall, without having to connect some wires, or flip a switch everytime I get in the car. A wire from one electrode needs to go to negative and the other to positive of your car battery. I just ran the wires up to the top of the hood so I can connect them when I get to my car and tuck them in neatly the rest of the time.

-updates--Going through the firewall wasn't as bad as I thought. I just looked under the steering wheel and saw all the wires running through a rubber stopper. I rammed a fishtape through there and caught it inside the hood. I pulled 1 wire through and cut it. To turn it on simply connect that 1 wire back together. For now I am using wire nuts but it shouldn't be a problem to connect it to a button or switch. I took apart my dash because I was going to connect it to the rear defrost button(I have used it maybe twice in 3 years) but there was all kinds of circuit board wiring hooked up to it so I said forget it.

tep 7ResultsI have a 2003 Cavalier. The worst mpg I ever calculated was 28. I was purposfully flooring it every where I went just to see what the worst case scenario was. The best I have ever calculated was 45 while following closley behind truckers(they sure hate that). On average I fill my tank up and go 400 to 420 miles before my "pull over and get gas" light comes on. When my light comes on I am able to put 13 gallons in the tank.400/13=about 31The electrodes lasted for half a tank and I got 500 miles out of it. Assuming I got 200 miles out of the other half as usual: 500-200=300 300miles/6.5gallons=46mpg46/31=1.48 thats a 48% increase in fuel economy!

-updates--With the graphite I got 510 miles out of a tank. 510/13=3939/31=1.25 a 25% increase in fuel economy. I'm sure that if I increased the size of the electrode the mpg would increase. The pencil lead is just so small. I will update again.

P.S. My wife ran off with the camera to a florida vacation in the middle of my build. Thats why there are no pictures of the graphite electrodes. When she came back the camera wasn't working.

step 1Tools and MaterialsThis page ended up changing through the process and can vary depending on how you choose to improve upon the design I used.Tools:

knife or stripperssoddering iron(not essential but saves time)screw drivervoltage tester(depends)*drill*#7 bit*1/4" tap*may change depending on the electrode you use and how you connect it to the wireMaterials:(Keep in mind all the materials I used are "borrowed" from work or I had around the house so they won't be the most effective solutions. Be creative with what you use)

Plastic container (I used a grape juice bottle)High temperature silicone sealant <-expensive; regular silicone sealant MAY workWire (I used some left over wire from the amp that went in my wife's car, 14awg)Teflon tapePlastic tubing (I had to siphon gas once to change the fuel pump and had this hose from it, not sure why I kept it but I'm glad I did)salt (for an electrolyte in the water)Stainless Steel Electrode(update: THIS WILL NOT WORK)I put this one on bottom because it will have the biggest explination. I am told stainless isn't esential but will not corrode like other metals. I also read that coiled wire would be the best type(i.e. pipe, plate, wire).Platinum would be your number 1 choice but who can afford that? I used some pipe I found at work.

-updates--I ended up using the graphite from 2 pencils as my electrodes
