Introduction: Bio Gas Generator. (Small)
BIO GAS GENERATOR (SMALL) Natural gas producing device,that uses the process of Decaying matter to create flammable gases,Decaying Matter will be Animal Droppings To create Methane Gases.
(If anyone has seen the movie "Mad Max" beyond the thunderdome",will remember the whole of barter town was fuelled on and Powered By "Pig" Droppings/Guano Running Turbines with Methane gas)
This has long been a widely used and abundant source of free energy in gaseous flammable fuel form,and has many applications to power devices such as Rocket Stove Additives! ,Bunsen burner Fuel,Or the flammable gases could be used to collect energy with pelter cells,once a stove is ignited via the gas,electrical power can be converted from the fuel !
In the UK temperatures are not so stable or warm,as such accounting for the Cooler climate it may take any time from 3weeks to a month plus or even more for Non flammable Gases to dissipate,Bacteria needs warm and damp conditions to ferment and produce more gases so in warmer climates the reaction won't take as long 2 weeks maybe,before Flammable "Methane" Gases develop.
Step 1: Materials & Parts Needed.
1: 2 Litre Cola Bottle (Or more linked together in/on a line for more gas production)
2: 8ft of Plastic Tubing/Piping,Aquarium/Surgical/Garden whatever kind of tubing you can get hold of.
4: Hydroponic Drip feed connectors & T section. If not available craft one from 2 pipe sections.
5: Plastic Tube Pieces (Not pictured in/on device)
6: Animal Droppings/Guano/Dung (As much as needed leave room for gas build up)
7: Gluegun & glue for sealing pipe fittings to bottle cap.
8: Boxcutter or Exacto Blade,for cutting bottle cap and tubing.
9: Blue-tac/Stick plastic.for sealing ends of pipes will keeping unsealablity.
Step 2: Construction.
1:First collection your pipe fittings and T section pipe fitting,if not available create one by cutting two, 1inch pieces and super gluing them into a T shaped pipe/tube,grab the bottle top/cap and cut a hole the diameter of the bottle top insert the T section about 2inchs into the inner bottle cap/top,with the double pipe T on the outter/top of the cap itself,And then Hot Glue In place,then attach a pipe to both ends of the T section. (one end will be connected to the collector not pictured or created in this instructable see link,and the other end to the apparatus stove/burner etc)
2:Next Decaying matter collection,gather as much as needed,rabbit pellets are a good source of methane rich material,as is horse,pig & cow droppings,ware gloves & goggles while handling any such material as it presents an obvious health hazard if a splash gets in your eye or on a lip,use a wooden dowel or stick to push said material into the small opening of the bottle itself and fill around halfway to the top,add water just below the point at where there pipe from the top will protrude into the bottle,and mix it around nicely with the stick...now use a old rag or dry grass to wipe clean the top of the bottle cap screw point.
3:Last checks before you screw on the top,as you will not want to touch it after its been near such materials,so fill a bucket with water and place the Bottle cap and T Section along with attached pipe under the water and blow into all tube ends one at a time looking for bubbles of escaping air as you do so,if there is glue more around where there is escaping gas,and check again.once done,screw the top and pipe arrangement in place,and leave the bottle to stew/ferment and work off gases you have no use for,carbon monoxide/dioxide etc,try leave in a corner or somewhere the temperature will remain relatively constant and you're done.
Step 3: Storing Gas & Possible Uses.
Storing gas as always will be the most difficult and annoying part,as will releasing the gases building up from the reaction inside the bottle.
A collection device will have to be made separately. follow this link to another instructable for the creation of the collector.
Possible uses are as an additive to Rocket fuel stoves,in order to convert into electrical power by using peltier cells,adding a gas input to a rocket stove along with conventional fuels for it,twigs/paper/leaves,will create faster burning times with more heat created and more power harvested,Attach to a custom Bunsen burner in order to heat up your liquid and or chemical experiments is also possible.
We have a be nice policy.
