Hi Really need some help with this one, have searched everywhere but cant seem to figure it out. I know there is probably a very easy solution i'm missing so please help. Basically I want to compress CO2 at around 80 psi into a hollow metal. I have drilled a micro hole and created an opening (about 2mm radius) into the metal. My problem is after I compress the CO2 in there how do I remove the compressor nozzle and seal the hole without the CO2 escaping. The metal is small and there is no place for a valve. Is there such a thing as a self sealing removable valve? Or could I use a valve with two openings and pump liquid metal (that would than solidify) and seal the hole so I can remove the compressor?

I want to store hydrogen gas(not browns gas) in some kind of pressure container. Since the propane tank is not a good idea from your forum, I was thinking about using a truck tire that could be pressurized to 120 psi. What are the hazards in this process. I would suck out the air from the tube tire with a vacuum pump and then generate hydrogen gas, compress it into the tire. Will it work or will it become unstable and blow up?.

So the other day i was talking with my friend and he told me that gas can leak out of a metal tank. he said gas can leak out of scuba tank going through the metal just like it goes through a latex balloon. so i wanna know is this true? could gas leak out (given enough time) through a 12 gram CO2 tank used for airsoft for instance?

There is a big movement going on about making your car get better gas mileage with different kits and fuel additives. I read about Ethos over atIncrease Gas Mileage Increase Gas Mileage. Is it really possible to increase your gas mileage with simple solutions? Maybe the oil industry really is trying to keep a tight lid on this whole industry....

I'm afraid you're going to hear more than a few bits of money-saving advice from me! I'm a self-proclaimed Queen of Tightwaddery! We've been honing our skills at our house since I quit my job 3 years ago. I was determined to be a stay-at-home mom, and discovered that by being careful, I could save as much as I was bringing home, and be happier doing it! Hypermiling is one way we save money. The term "hypermiling" is new to us - we read about it in Reader's Digest a few months back. Some hypermilers go crazy and take risks. In our house, we've chosen a few things we can do to improve gas mileage without risking our lives or ticking off other drivers. Here are a few that anyone can do:1. Watch your speed. Driving 75 on the freeway might be legal, but it uses a lot more gas. Keeping it to 65 (or better yet, 60) can save 2-3 miles per gallon or more.2. Avoid accelerations and braking. While this might sound like using cruise control, it goes beyond that. You want to make your speed changes gradually, a) allowing your vehicle to stay in the highest gear possible when accelerating (lower rpms), and b) taking advantage of momentum (coast, don't brake, whenever possible). So if you see a stop sign ahead, stop accelerating sooner and coast. Perfection would mean coasting to a stop without needing the brake (but consideration for drivers behind you usually prohibits this!). See how close you can come! When accelerating, do it gradually, allowing your vehicle to shift earlier (let up on the gas a little to encourage the shift). If you see a slow-down or big curve ahead, ease up and leave room so you don't have to hit the brakes.3. Get the lead out - of your vehicle, that is. I improved the gas mileage on my van about 1-2 mpg by taking out the back two (unused) seats! Don't use your vehicle as a storage unit!4. Check your tires. Under-inflated tires will cost you a mile or two per gallon. There are lots more ways to improve your mileage and save money. Google "hypermile" or "ecomodder" and learn specific things you can do with your make and model of vehicle.Do the math - you might be surprised how much you can save. Here's an example, using a 20 gallon gas tank and 20 MPG:You can drive around looking to save 10 cents a gallon on gas. Assuming you find cheaper gas without burning a lot of it while looking, you'll save $2.00 on a fill up. OR you can apply a few of the principles listed above. I improved my van's gas mileage doing only those things by about 5 mpg. 5mpg x 20 gallons is 100 extra miles I can go on a tank of gas. At 20 mpg, that's a 5 gallon savings - at $3/gallon, that's $15 per fill. (That's like finding gas 75 cents per gallon cheaper!) How many times do you fill in a year? You do your own math and see the savings! My husband drives a lot and is squeezing 41-44 mpg from his car rated for about 33 mpg. With all his driving, he figures he's saved about $175 per month over the last 3 months.All this hypermiling has made us very aware of how much driving a mile costs. Now we look at every trip out in dollars and cents. If you had to pay $2 to run to the store and back, would you still do it? (If you're going for a gallon of milk or a dozen eggs, tack the $2 in gas onto that item - is it worth it?) We've started combining trips, planning ahead to avoid extra trips out, carpooling, using the car instead of the van when we can, etc, etc, etc.Awareness is the first step. Try it and see!

Everybody knows that rising gasoline and fuel prices are taking a toll on consumers' wallets. But few anticipated this problem: a shortage of numbers at gasoline stations. Since gas prices have easily surpassed $4 per gallon, gas stations in New York don't have enough 4s to advertise their prices--so they've had to improvise and make DIY numbers.Of course, with gas expected to hit $5 per gallon soon, some stations are prepared: On Monday, at a BP station on Coney Island Avenue and Lancaster Avenue in Gravesend, Brooklyn, a 2 had been turned upside down to make a 5 for the large sign on the corner.When the price hits the $5.20 range, though, they'll probably have to start improvising again.New York Times

Hey guys and girls, I am after a supplier for gas inlet valves, or a standard or anything... Basically I have a laser tag system that I want to add high pressure air recoil to, but I want the air supply in a removable magazine, that will then connect to the gun and go through a blow back valve once the trigger is pulled etc. Now, the problem I have is the connection between the magazine and the gun, to allow the gas to flow through, I know airsoft guns have recoil magazines that they can use, (Im in Australia, so i don't have access to these). But would really like to know where I can get some of the parts from. Or designs maybe.

Years ago I saw a documentary about an African country which most villages and towns use bottled gas to cook. One guy had made a stove from an empty gas container that split water, using a car battery, into a usable flammable gas. It was very basic; the electrodes were nails and the amount of electricity it used was minute, (shown by a very dim bulb in part of the circuit); it worked very well, just like a normal gas stove. The guy had been kidnapped three times and his family threatened by the people who make their living from selling gas. Here was Trevor Baylis, (The man who, in 1991, saw a programme about the spread of Aids in Africa and set about developing the wind-up radio), with the guy using the stove to make a meal. Trevor Baylis was going to take this project on and allow everyone to have a very cheap and eco -friendly cooking fuel. I can't seem to find any info on it using Google....So my question is: Did this ever happen? Thank you.

I need a relatively simple way to produce a few milliliters of dry H2 gas. I do NOT want HHO and I do NOT want electrolysis of water, I also would like this method to produce little to no water as a byproduct. I'm looking for generators because the minimum tank size of hydrogen I could buy (unless someone could locate a supplier in the UK that would sell me something the size of a propane tank or smaller) is far too large. I'm Interested in a chemical reaction or hydrocarbon cracking method that would require a maximum of 200 degrees C if it requires energy input, but I don't mind if it's terribly exothermic (unless its an thermite-like reaction, then we have a problem) since I have a very effective cooling system in place for it and the rest of the system. I forgot to add what its for, glow brazing. It'll be ionized and remove surface oxides while simultaneously heating the parts to be brazed.

Hi,Pennsylvania State University researchers last week announced that they have developed a method of producing hydrogen gas by combining electron-generating bacteria, acetic acid and less than .2 volt source in a microbial fuel cell. Info at this URL... http://afp.google.com/article/ALeqM5iXbROJgdF3_6BtG3TZFEs9hiw8CgI first heard about this last week on NPR's Talk of the Nation. Here is NPR link - http://www.npr.org/templates/story/story.php?storyId=16343702&sc=emafThe researcher who led the project Bruce Logan, the director of the Hydrogen Energy Center there said last week on the show that this was actually a relatively simple process.He claims 90 percent efficiency. Also claimed is that the process produces 288 per cent more energy in hydrogen than the electrical energy that is added to the process.I would love to build one small scale and combine it with solar panels. Or maybe try to generate some hydrogen and try using it as a fuel supplement for my car using something like this - http://www.hydrogen-fuel.ca/ . Anyone willing to tackle this one?

Hello, I live in Arizona so we just tried to use our gas wall heater for the first time tonight (hasn't been necessary before now). This is the type of heater we have installed in our hallway/bedroom. http://www.homedepot.com/buy/williams-monterey-50-000-btu-natural-gas-top-vent-wall-furnace-5009622.html#.UJ-qvYaElhE I lit the pilot and then moved up to the thermostat that is mounted on the wall. I moved the dial from the left (which starts at 50) over to the far right (which stops at 90). I felt and heard the thermostat click over at about the 65 degree mark (which seems accurate to me), but nothing happens. Usually, immediately after the thermostat clicks over, the gas flow increases, and the heater starts to do its thing. I have included some pictures of the thermostat, and heater itself. If someone could tell me which connections I need to check with a volt meter, it would be greatly appreciated. One thing I want to add, we had a light socket go out on the same wall about a month ago, that doesn't seem to be getting any power. I have tried several new bulbs and it doesn't work. So I would need to figure out how to check if the thermostat is even getting power as well. It's possible that the thermostat isn't even getting power. Thanks SOLVED: Thanks everyone for your replies. It actually was the solenoid inside of the heater, but the good news is it works fine, a wire just came loose. Everything is working great now. I wouldn't have thought to look there if it wasn't for your comments. Thanks again!

The exact setup I have is a little difficult to explain, but basically I'm designing an extremely simple heat engine, based on boiling ethanol, and need to be able to mechanically alternate the flow of vapour. I have a little boiler, sealed except for a pipe out of which the vapour escapes. This lifts the column of ethanol in the pipe, pouring it into a water wheel which turns. The ethanol then runs back through a second pipe into the system to be pumped up again. It works, and fairly well since I'm not looking to get a lot of power or efficiency, but only if I pinch the tube on and off. This allows the bubbles to collapse, which sucks in more ethanol to replace them. When I release the tube the bubbles rush out, lifting the eths, and repeat. I have two valves to keep the system one directional. So now I'm looking for a way to automate the opening and closing of the gas feed. I've been trying a few things but nothing seems to work well enough yet. The other consideration is that; due to the nature of the larger project, whatever I use has to be extremely simple to construct, preferably from reclaimable materials. 1 second on, 1 second off seems to work best. Any ideas? cheers, Daniel.

Asked by elainedc 6 years ago
Sorry if it is in the wrong section of the forum. If it can be moved to a better place then do so. This is a quick mention to anyone that is playing around with any burners such as: wood gas generator bio-gas wood gasifier 'hobo' stove I am not severely concerned but it did happen, I think it needs a mention, as it is for everyone's safety. After playing with wood gas and attempting methanol creation from a small gasifier unit for a few weeks, I had started to realize that each day I had a most annoying headache / migrane in my frontal area of my brain / head. They ended up getting so bad that my body could not tolerate them anymore and started to go into shock, causing a rather painful, endless throwing up session for many hours each time even. It came to a point where after 3 weeks of playing with a bio-gas generator for about 4 hours a day had started to lead me into temporary blindness an hour and a half at a time. This was when I was concerned as I could not read any more instructables :( After a quick jot to the local doctors, I explained what I had been up to and I was correct. I had given myself the rather classic, and very close to death, carbon-monoxide poisoning where my doctor insisted I go to emergency at the hospital ( 2 hours away ) immediately and have someone else drive me. Pretty much equivalent to staying inside a garage with your car running for 5 hours, all the doors closed. I was very close to severe carbon monoxide poisoning and death. At the hospital, blood was taken, analysed, and they had discovered large traces of C02 that they attempted to flush with some oxygen, but this only works to a point and they mentioned that nothing else could be done apart from telling me not to use or be near any smoke sources for at least 3 weeks and I should recover fine. I am still playing with my wood gas generators, and attempting to make methanol, but these days, after 3 days ago, I take further safety precautions to make sure it wont happen again. Such as: ventilation / exhaust fan ( I WAS OUTSIDE WHEN I WAS POISONED! DONT TAKE THIS LIGHTLY! ) keep a distance, find a better way to ignite / extinguish the burner keep your face and body out of the smoke dont watch the flames / smoke from above for any longer than 2 seconds do not taunt the Criosote by-product of wood. I am not sure which is more toxic. The smoke or this. ( criosote / bio-crude, whatever you want to call it, it is the condensate of the burner unit containing more chemicals, very stinky) do not store criosote indoors withough a sealable container ( the smell likes to soak into things, like my kitchen ) if you know what you are doing, keep oxygen tank nearby use all protective clothing and masks, etc. There was a small arrogance in my head when playing with these units. And that is simply that I was thinking 'it is just smoke'. Wood gas generators are generating a much more toxic smoke than just sitting around your camping fire and should not be considered to be something to play with, without proper valves, pipes, burn off points etc. It contains on some scale: carbon-monoxide, methane, acids ( acetic ), tar and many other defects that will cause you issues if you are not careful. Keep it safe guys, this was a rather difficult one for explination, but I do not want someone other than me to be in that same sickness / position as I was with the poisoning, as it is the most painful experience I had yet had. Worse than me hitting a tree head on at 80km/h. Worse than falling 2 stories off a cliff onto rocks. Worse than being hit by a car and thrown over it's windscreen. Worse than the feeling of an unsuccessful home made rocket launch. All of these above I have had happen to me, and the poisoning was by far the worst and I was scared more for my life than than any above accidents. It is not a very nice feeling, it is a deathly, sickly, useless feeling, blindness is not far away from death if found in this situation. Oxygen / fresh air is the only thing to help you if poisoned, even if in hospital. Keep it safe guys. If you want me to write up a full on poster on wood-gas / wood-heater safety I can or even just a propper write - up on general safety with this smoke and the wood gas units etc. Ask please and I will. Hospital staff will most likely give you 'items of interest' for instructables if you just ask them too. I have a heap of things from a stethoscope to vials to 'red dots' for homemade ECG machines. They tend to like crazies like me that make weird stuffs .. i hope ive gotten the point across anyway.
