$Cash from Trash$ Make your very own electricity!!

Picture of $Cash from Trash$ Make your very own electricity!!
   Hi guys! Today we will be making something I'd like to call the "EGG". EGG stands for "Electricity-from-Garbage Generator". This simple machine produces electricity without polluting environment. It is easy to make, all materials are cheap and even can be found in the backyard of your house! And of course it DOES make cash from trash!! Still not involved, so get involved! This machine let you recycle EVERY piece of trash!  If you recycle plastic, glass, paper and metal in the ordinary way AND use this machine then you don't have to use bins any more! Sound's weird? Then see how it works:

   You put the trash (only organic materials ) in a container (see pictures ), then you wait till the bacteria eats "Digests" the trash. In this process a kind of "Biogas" called methane is produced. This gas is flammable and produce CO2, but it produce 50% more energy for the same CO2 production than gasoline so it doesn't pollute environment very much. After the biogas is produced, all you have to do is to to collect it in a hose and store it in a safe place because it explodes if touches air. So you have to store it in a place far from air, for this purpose you will make a reservoir filled with water (see pictures). Then another hose will transfer the biogas to the boiler in order to make electricity using steam engine or you can use biogas to cook, heat water and many other uses.

   So, did you get involved now ? If your answer is "yes" then continue to step 2, if your answer is "no"  then visit this site  to see that this machine is safe and used in larger scales or watch "Planet Mechanics" in the episode called "cow power" to be sure.

Is it good to use non biodegradable masses in this project?? i guess it also produce methane gas?! plese reply asap

Methane is a hydrocarbon (CH4) and all hydrocarbons produce CO2 and water vapour when burned.

It produces CO. But I read that it does not pollute environment!!
CO does pollute the enviroment, yet it does burn, and if burned it will produce CO2 + H2O :)
It produces CO2 if supplied enough oxygen, CO if the oxygen is restricted during combustion. CO, carbon monoxide is a poisonous gas that kills.

burning anything pollutes, what you should keep in mind, though, is that if whatever waist you put in the digester to be consumed were instead moved to a landfill, It would still produce methane, which- unburned is a greenhouse gas almost as prevalent and harmful as CO2, but it would not produce electricity.

Further more, in reference CO (carbon monoxide) it can be deadly, but so can any other gas. look at it this way, you release more carbon monoxide driving to and from work than you would probably produce in a whole day using methane produced by a digester of this caliber, its essentially a harmless way to recycle your waste and lower your electricity or gas bills.
I guess methane exploding on contact with air explains the flashes of light I see at night in the cow pasture and the soot I see on the cows' tails in the morning??
this is a cool project that you have made.i want a little clarification.if we use this methane without stopping for how much time this gas can be used for cooking.

cool i might use this to heat a home or cook in a gas stove

While this is a legitimate way to produce a combustible gas, there are some problems that have not been considered, as well as some misleading statements that I think should be cleared up.

1. Methane is an organic gas, and is the principle component in "natural" gas. Chemical formula is CH4. Burning any organic material of any kind always produces CO2. CH4 + 2 O2 -----> CO2 + 2 H2O

This is pretty basic high school chemistry.

Note: while CO2 will be produced, the amount of sulfides and NOx compounds (the really nasty stuff) produced should be negligible as compared to coal and diesel.

2. While this method will definitely produce methane, it will only produce a very small volume. You would need a much larger reaction chamber and a lot of biomass to produce a usable quantity of gas. Furthermore, if you plan to store the gas, as opposed to burning it as it is released, you would need some way to compress it. And, of course, that would require energy.

3. The assertion that methane contacting air will explode is false. Methane is combustible and concentrations between 5% and 15% in air are explosive, but only if an ignition source is available. Of course, if you plan to burn it, you have to have air available as well.

Overall, this idea is workable, but only at large scale and with the right equipment.
Buck Minster Fuller, (I think), designed a biogas producer in India to be used in villages. It was a cement tank with a floating cement lid that had a means to introduce bio waste of all kinds, including human, and also a way to divert the methane to a cooker or heater. The heavy cement lid provided the pressure. Not necessarily very efficient, but effective. I read about it years ago but can't find much about it now.

Visit the following link and see the book in it. On the book you can see a small scale of the digester and it's used for cooking:
Actually, you don't need to compress it because water produce enough pressure (water make pressure on methane causing it flow through the hose). If you don't have enough pressure, then you can put heavy thing(stone, etc.) on the reservoir to produce pressure. But don't forget to rope it with the reservoir!
And you can watch "planet mechanics" in the episode called "cow power" to see that methane explodes when contacting air!!
Then why doesn't natural gas explode when released to the atmosphere? No, pure methane will not explode with exposure to air, but if an ignition source is available, then an explosion may occur. An ignition source may only be static electricity, so it is quite dangerous.

And yes, your idea of using a submerged vessel would suffice to capture the gas. That is a pressurized system, although I'm not sure how much gas you would be able to store and what size water tank. It could get rather large.

Did you watch the episode? they made an experiment to show you it explodes! And you can buy the book and chick it.

Very useful and interesting!

Excellent machine, and God help you, and God willing, for the better of them and we want you moving in the other machines more creative and beautiful design of these and you sincerely

This is a great instructable for getting more people into using alternative energy! But I have to contest one point:
Methane is multiples stronger in producing the green-house gas effect than carbon dioxide. In fact, the thawing of the permafrost is quickly becoming an accelerent for global warming because of the frozen methane being released. That said, burning it- like you are doing here- is a smart way to get energy out of an anaerobic process to release the carbon dioxide that would have been released had it been broken down aerobically anyway.
Other, than the nit-picking, this is a great job! Keep up the good work!
baker amin (author)  1tri2god3 years ago
Thank you. Hope you vote for this instructable!
The organics would rot and release methane anyway.
You're absolutely right, if in an enclosed space like this, or if packed down in a landfill. But most times, organic material decomposes with enough surface area exposed to the environment that it will decompose aerobically. In fact, this is the purpose of composters like tumblers or of the "spread around your garden" method of organic recycling.
So, its all about how you let it rot.

And, lately, the landfills have been wising up to the free energy they've been producing with anaerobic methane production to the point of capturing the methane to run in gas turbines for electricity production!

Good instructable! Do you use any yeast or additives to make the digestion faster?

Do you have to clean out the digester occasionally?
baker amin (author)  sam D3 years ago
The best materials to add to the digester is the manure of cows or even human manure. And yes, you can add something called "digester" which helps in this process. See it in planet mechanics in the episode called: cow power.

Some materials don't digest fast such ass plants. And a liquid will appear in the base of the digester so you can remove it and put it on trees, it's useful! You can just "stir" materials in the digester from time to time so the methane can raise up.
