Visible Gas? Answered

I wan't to fill a chamber with hydrogen, have a chamber of the same size linked with it, with a heavy visible gas in it, then as I pump out the hydrogen the heavy gas displaces it and I can see when I need to stop pumping and refill with hydrogen.  What gas can I use,  I know just about any visible gas will work because hydrogen is the lightest, but it would be nice if it was heavier than average air so I could allow air to flow into my heavy gas chamber to displace it.  Or can I just die the air with some kind of smoke from my smoke machine. Yes hydrogen is extremely explosive, so this would be on a very, very small scale with hopefully 0 oxygen.

Need a Gas Tank

Hey guys, this is my first time on the forum section of the instructables! Not a bad place to be, really. So here's the thing. I have this old scooter that I've had for as long as I can remember. It was the very first thing I rode that was powered by a motor and my father bought it for me so I could get ready for my first motorcycle (Which was sadly stolen about a year ago :/). Last year, my dad went back to our hometown to visit family and he brought it back with him, but there was one problem. We have no gas tank for it. I have NO idea where it could have gone or why it wasn't brought back. Oh well though. I have this scooter, the same as Wesley666 does. I'm having trouble finding the gas tank on my own. Notice that there is a gas tank that I took from a weed eater just to try it out. But I'm not sure it would work out very well. I mean, look at the size comparison between the two? I also want to keep original parts on this nostalgic machine. Sorry if the pictures are oriented weird, but these are taken with my phone.You can see from the thread posted above there is a picture that shows a blurry close up to the gas tank and I can't really tell what it says. "Something EBR Motor". Long story short I need to get that gas tank, maybe even the gas line that comes with it, in order to get this thing working again. Does anyone know of the brand name of the scooter so I could get the original parts I need?

How to compress air into a hollow solid without a valve?

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?

Hyper-mile!

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!

Help Me Establish Gas Station Fraud- By Exposing Fuel Manipulation.

Prelude:Every week I only ever travel the same route, at the same time, with the same amount of traffic on the road.I fill my cars fuel tank once a week, with $50AU of petrol.The prices lately have been stable and around $1.30AU/LWhat this post is about is the fact that due to me travelling the exact same Km's per week, I have noticed a significant difference between the two petrol stations fuel that I fill at.Can anyone educate me as to why when I fill at one station I get 8 days of travel and when I fill at the other station I only get 4 days of travel?Once again I am filling the same amount of fuel at each station, just one stations fuel (Major corporate outlet) seems to be of a much lower quality.Is it possible that something is a-miss with this situation. Is there a variable im not considering?After 4 months of weekly refills I feel that conclusively, one stations fuel seems to combust better than the others.Is this possible and if so are there any home experiments I could try to prove my theory via testing the fuels combustion/quality.I only write this as I sit here on a week, where I was forced to fill up at the "suspect" station. Im on day 3 now and my fuel is red lining... What is happening?I know the difference of 3 -8 days is a massive, surely others would have noticed this also. I thought I was mistaken the first few times it happened. But now I am positive, something is wrong.I might add, I use premium fuel with the same octane level at both stations.Could that be it? Would they be mis-quoting the octane level in their fuel? That is the only thing I can think of.

Help with fire concrete/ forge making Answered

Firstly "Hello all", I am a long time lurker, first time poster. With that out of the way, I am gathering materials to make a small gas forge to cast some bespoke jewelry for my lady wife.

Wood/Biomass Gasifier? Answered

I have always been interested in the principles behind gasification, but I have had some problems fully understanding it due to some differences in the devices I have seen.  I have noticed two real differences which I can only describe as closed and open systems.  Closed systems have some heat source which heats a closed container of wood, this wood is directly fed to an engine or flame.  No air can enter and their is no combustion prior to reaching a torch or the engine.  The open systems I have found to be more common but I can't really grasp how they work.  The fuel source is lit and then the smoke is captured, but this captured smoke is then somehow flammable.  I just find it difficult to understand how this can work in an open air-fed system.  Does anyone have more details on the differences between these two styles?

I am not very experienced in auto mechanics so I was wondering if anyone here could figure this out.  PS : This option of shutting down cylinders was also available in older Cadillacs I beleive it was called the 4-6-8, which shut down either 2 or 4 cylinders.  This engine however, was known for it's problems, which is why I was wondering about doing this.

And is there a way to manually adjust the ratio of air-to-combustible? The reason I ask is because I was hypothesizing whether or not it would be feasible to replace gasoline with a more efficient combustible, and this combustible would greatly depend on what is actually put into a modern petroleum-based car engine's pistons.

Solution to turning on/off gas: new pump design.

I've been working a couple weeks now on solving the problem I posted here on how to improve my pump design by alternating the feed of ethanol vapour. I got good feedback but ultimately all the solutions involved mechanisms which were going to be somewhat tricky to build and source, which is against the brief of the project I'm working on; being an open source solar tracker concentrator makeable from scrap. In the end I solved the problem by largely redesigning the whole pump. Since it's driven by boiling ethanol, rather than add an extra mechanism for turning the feed of vapour off and on, I reduced the amount of ethanol being boiled, so that it boils itself out after an appropriate period. The vapour is then able to collapse fully, which sucks in more liquid ethanol and refills the system. 1. At the bottom right is the boiler, which holds about 2-3 ml ethanol. 2. This boils and the vapour enters the 'chamber' (the half blue, half white (liquid and gas)), forcing out the liquid, which pours into the wheel, ending up in the main reservoir. 3. This continues until the eths in the boiler has boiled away to the extent that it can no longer overcome the rate of re-condensation in the chamber, which starts to suck, so to speak. 4. This draws liquid from the reservoir, which passes through the boiler, shutting off the boil, the pressure drops quickly and the chamber and boiler refill with liquid. 5. Two valves (the only moving parts, besides the wheel) keep all this going in the right direction. 6. Repeat. The wheel provides the motion for the solar tracker. It's not in by any means powerful or efficient, but the whole thing can be made from a bit of metal tube, some thin pipe, a glass jar and two valves from bike inner tubes (plus a paint tin, bike wheel bearing and some drinks cans for the wheel). I haven't had a chance to try it in the field yet, but powered by a candle it seems to work fairly well. Blog entry here, will post photos and videos when available.

Would you guys like an instructable for this gas powered bicycle?

I was wondering, who would like to see a detailed instructable with step by step instructions, lots of pictures, and parts lists for how to make this powerful motorized bicycle from scratch (without a kit)? The motor is a heavily modified 79cc horizontal stroke predator engine from harbor freight. The bike has a top sustainable speed of about 40mph. It also has enough torque to accelerate uphill, take off from a standing start with no pedal assist, leave Lance Armstrong in the dust, and do wheelies even with my 29" tires. Gearing can be adjusted for higher top speed at the expense of having less acceleration and hill climbing power. (Although in all honesty, I wouldn't gear it to go much more than about 45). Other features include an automatic clutch, the ability to get 170 miles per gallon, allowing you be cooler than all your friends, and costing a fraction of what you'd pay for a vespa. If you want me to make an instructable, comment below! Also tell me whether you might actually build one, or whether you just want to see how I did it.

Construction ideas for this concept?

Recently, I have been working on a gas 'vaporizer' that evaporates gas before being fed into an engine. During my short-term experiment, I found that this saves ~70% (+-20% for crudity of measurement.) This works because the vapors will burn more thoroughly and cleanly, leading to higher apparent efficiency. Below is a basic diagram of how the system works. You can see there is a container that is half-full with gas, and a hose goes down with many small holes. As the engine's compression draws a vacuum on the container, air will come up through the holes. As it rises, the gas-air surface area rises dramatically, leading to the vaporization of gas. To further increase the surface area, I also added a felt liner on the inside to allow the gas liquid to rise and evaporate. The final mixture ends up very rich, so to compensate, a 'T' fitting has been added to allow air to mix in with the vapors/fumes. Some valves have also been added to control the air inlet (similar to a 'choke') and the amount fed to the engine (similar to a throttle. In fact, it is possible to use the original throttle or choke as a throttle on the carburetor on my tractor!) The problem is: My original design utilized a plastic folgers coffee can, and the flimsy plastic top was hot glued to a thicker plastic cutout for strength and support. Since most glues will dissolve in gasoline, including hot glue, it could not be used. most did not hold anyway. I also tried JP weld plastic cement and it did not hold at all. I had to trash this build. I did, however, get enough use to run the tractor for several minutes while testing gas use. I found that the tractor used nearly twice as much simply running on gas than the fumes. I did not have the float valve and electric pump hooked up with the prototype. Also the 3/4in housing I used may be a bit constrictive and also seems to get slightly damaged by the gas. It will not be a long-term solution.  So I need to redesign the project, and I am thinking of using a 1-3 gallon bucket that is sealed or a gas tank. I need good almost air-tight seals on everything. I am asking for any ideas related to the construction of this device and any tips you may have.

Has anyone ever burned wood inside an electric or gas oven? I was thinking of modding and oven with refractory cement, and a water mist sprayer,for bread baking, when it occurred to me that broken gas/electric ovens are cheap, mostly air tight and temperature resistant,to say the least. Obviously burning wood in them is not an UL approved usage, but clearly these devices are tested a lot more than your average barrel stove design.. So, any experience with this idea?
