    So the tank is just slightly larger than the bottomless "gas holder". And the open bottom gas holder, more properly called a collector or trap, floats, bottom edges submerged, in the slurry. The guide tube and the close proximity of the sidewalls of the two "cans" (plastic buckets), one within the other, keep the collector/ holder upright and oriented so as to maintain the bottom edges in the fluid, trapping the gas as it rises from the slurry, not escaping under the bottom edges of the collector (floating dome made from a plastic bucket), and out the top of the collector, through the couplers and up the gas "pipe" (i.e. hose, a pipe is ridgid, a hose is flexible, in all technologies). From there it can flow to a burner, or be compressed into a storage cy...

    Wow, I only posted this once.

    Make Energy From Weeds

    Evolution has eliminated the problem of "wild bactetia sufficiently that modest control measurrs are all that is tequired.

    My weedwhacker does a great job to begin with. Soon to be run on alcohol, to produce both methane and alcohol.

    I am a little disappointed. A general description of the digesting bin and a photo are pretty slim. Where in the world can you get one, and what are the exact specifications as a reference. I have never seen a tub/barrel/bin like that in 61 years, 44 of them focused on this and other self sufficiency strategies. Not to mention years in commercial and residential construction and maintenance. A little to vague. And the linchpin of and only critical one of a kind item in the design. A 50 gallon drum needs some moderate level modifications.but the picture and the text are difficult to collate from the lack of labeling, or materials that are applicable...it is the centerpiece of the system, yet I get zero idea how to go about aquiring one.

The author doesn't even say what the thing is called by the manufacturer. Can't even google it. Just this picture is what I used, and it's triple walled? Please understand, I appreciate the time, effort, and info, but the author seems to think his readers are mind readers. Or that they have an encyclopedia of industrial containers in their heads. No clue what the containers product name is, or what it is usually used for, or where to get one. Just "anything like this is good". I also noticed a lack of an x-ray image or cutaway view, or a schematic for non experts to use in configuring one from other vessels. It is the only critical part of the entire apparatus.

    The oxygen gets depleated quickly beneath the surface unless the pile is very small, or very thin. That is why it is recommended to turn compost regularly, especially in warm weathrr.
