You mentioned Nenana, and I’m assuming it’s Nenana Alaska. We are looking to build one on our farm in Alaska as well. I am an engineer and would love to compare notes.
Hi I am planning on taking my home in Cornwall UK off the grid. I am going to put a generator in my garage and rig it to a 10 kwh solar system. I have a wood burning system in my kitchen that powers my heating and hot water. The only piece of the puzzle that is missing is the convenience of our gas sentral heating boiler. If you are interested in my project please get back to me*. Regards Martin steele
I have been wondering if you have a bio digester in a cold climate could you just let it go dormant in the cold months and then re start it when it gets warm? Instead of using up energy trying to keep it warm.
Yes, I currently manage the Home biogas at the Nexus project at Appstate that Richard mentions. We let ours go dormant the winter of 2018-2019 and it started right back up once we started getting consistent 70+ degree weeks in our greenhouse. Hope this helps!
Toy Gangster so I heard him talk about other gasses in the output. He didn’t say how they separated them. In the bio generator I’ve designed I was going to use a scuba pump to get high gas pressure. Boy was I glad I didn’t need that much pressure. I was worried about heat generation in the pump and it becomes one big bomb. I didn’t quite catch how much pressure though. I think he was too nervous. My bioreactor you just feed it and out comes the compost at the end eventually. I never thought of using the liquid for my plants. Got me wondering if the particulates would be small enough to go through a soaker hose. Probably not.
@@rosstemple7617 So Ive done a little bit of research into that. So the output from our anaerobic digester is roughly 60-72% CH4, 39-27% CO2, and 1% trace gases (hydrogen sulphide, carbon monoxide, nitrogen, water vapor) respectively. Ill prelude with my sourcing and say check out "Lucky Hill Farm" here on youtube. The guy uses bleach water to scrub out the Co2 and steel wool/clay pellets to scrub out the hydrogen sulphide (because it can corrode your equipment), then he compresses it using a gas bag and an air compressor. Low tech, looks like a good proof of concept, and no need to spend loads of capital on liquid nitrogen to compress your free gas. We're currently beginning research into using the effluent from the anaerobic digester in hydroponics systems. We did a demo test of this last year using an ebb and flow system and got pounds on pounds of delicious cherry tomatoes. I would not apply your effluent directly to the soil without appropriate dilution. Would be interested to see +living web farms do something similar using a biochar grow media. Cheers, keep building, and growing resiliency.
Toy Gangster where are you conducting this research? I don’t know why these systems aren’t mandatory for pig, chicken and dairy farms? They could cut their bottom dollar.
It would be fantastic if there was simply a set of requirements and barriers to methane farming instead of the extra yap flapping, forgive the bluntness, but I want to know how long to keep the waste before it stops producing methane, and what is a source for bacteria that are more productive?
It's definitely possible. You would need a UV system capable of disinfecting opaque liquids. I'm only used to UV water treatment, so I don't know much about opaque fluid treatment.
For crying out loud, they recycle digestate back to the 1st stage of the AD process to put mesophile (or thermophiles) into the fresh feedstock to start the AD process more efficiently. I hope these guys are seeking outside advice.
I HOPED THIS WOUD BE A DIAGRAMATIC EXPLANATION OF HOW TO BUILD AND OPERATE A DIGESTER. DO YOU ACTUALLY HAVE SUCH A CLIP OR DO YOU ONLY TALK ABOUT TALKING ABOUT DIGESTERS? A PICTURE OF HOW YOUR DIGESTER WORKS WOULD BE A GOOD START. WE ARE NOT INTERESTED IN YOUR EMPLOYMENT HISTORY.
Jason Bean a shame you can’t give a guy sharing knowledge for free, his due credit. Thank you to the presenter. This guy is too cool for free school and wants everyone to see him belittle this presenter lol.
I want to repeat i much i vallue this chanel. So much i allready learned from this. Thank you.
Cool stuff, I have to check out the rest
Is it possible to get a copy of your handout that you had? If so at what cost?
i want one
Can your normal gas stove use biogas w
Thank you good, but how to removeal of h2s not clear, can you please give any suggetion for small plan home use, gas without h2s
instablaster...
Steel wool in a tube, the s in h2s will react with the iron oxide.
It's a sacrificial style scrubber.

Was this in Europe in cold climate please, like UK? Thanks

Nice
Would running the effluent through a UV sterilizer take care of the pathogen problem and allow for immediate use on a veggie garden?
It's definitely possible. You would need a UV system capable of disinfecting opaque liquids. I'm only used to UV water treatment, so I don't know much about opaque fluid treatment.
I would suggest using an ozone bubbler to kill off pathogens before adding to your digester just leave it a bit so the o3 changes back to o2

Hey David, interested in what you have to say. What outside advice and resources do you recommend?
@David
Please elaborate.
Yes, and?

An interesting topic. A shame the presenter is so awkward.:)

It kept me interested! The weirder the better in most cases! Go weird jason. Be awkward
He had a great presentation
Have you watched any of the other living web presenters? lol
