Manure-Powered Generators On The Rise
Sunkist writes "The San Francisco Chronicle has a report on Marin County rancher Albert Straus that, after 25 years of work, began using a generator powered by manure. While this type of 'power' has been in use for a while, recent legislation has made it more widespread. From the article, 'The Straus Farms' covered-lagoon methane generator, powered by methane billowing off a covered pool of decomposing bovine waste, is expected to save the operation between $5,000 and $6,000 per month in energy costs.' Let's hear it for poop!"
Shit.
I am one of many. My idea is not unique, nor do I expect my voice alone to sway you. I speak in a chorus of opinion.
...but i'll take a shitload of fuel to power a city.

That's great and all but what does Tina Turner have to say about it?
What could possibly go wrong?
..and it arrives at the perfect time, the production of bullshit is at an all-time high!

Oh wait... (or is it "moo wait..."?)
So what's the waste generated from this? Obviously CO2, but what else? Is it considered "clean" energy? Is used poop as good at fertilizing as new poop? Would it work with human poop? Can I build a small version myself? Are their poop bylaws? (I can cover my lawn with poop after all..). And most importantly, does it run Linux??

I don't know if I believe this article... something smells kind of funny about it.

When I was a kid we would visit my Uncle's dairy farm. Even with him using a lot of manure to fertilize his fields - getting rid of it all was still an issue. They went to a system where they processed it to liquid and it went into a big liquid manure pond. I can remember watching their dog- walking around on the 'crust' that formed on the top of it. Every so often his legs would slip through. That was a nasty dog.
Eventually my Uncle's family farm went under and was auctioned off. I wonder if this kind of thing would have been enough to keep him in business? He now works for a big giant 'corporate' farm. Truth be told- from a purely economic perspective he is better off. He gets regular vacation (never had that with his own farm) and makes o.k. money.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
a generator I could run off my septic tank to power my house. But my whole family doesn't produce as much poop as one cow. Although when we have TexMex, we rival cows in overall methane production. But who wants to carry a mini-generator attached to their butt?
That's greenpeace FUD, really. There's not nearly as much CO2 staying in the atmosphere as there should be, and noone knows why not. The best theories are that the oceans (which are most of the planet) sink orders of magnitude more CO2 than all the land-based plants.
On the panel, an electricity meter began running backward, indicating that power originating from a nearby poop-filled lagoon near the town of Marshall was feeding into PG&E's electric power grid.
A well-fed dairy cow produces 120 pounds of manure every day, or 40,000 pounds per year per animal.
These cows are pooping money!
Happy Trails!

Our power company, SRP, does a similar thing with landfills. After the landfill is full, they tarp it and collect the methane in order to generate electricity. Then, a few years later when the methane generation slows down enough they remove the power generation equipment and build a public park on top. Three uses for one piece of land is not a bad idea at all.
In India, they call them gobar gas plants (more details in a 1971 Mother Earth New article). As long as one keeps the 30:1 carbon/nitrogen ratio, they can consume other organic waste too (grass clippings, urine, food waste, etc.). The only problem with them is that they tend to create hydrogen sulfide that makes the gas highly corrisive to iron equipment (some people use a filter of steel wool to remove the H2S).
Two wrongs don't make a right, but three lefts do.
Without forrest like we used to have...
Many forests around the world have been significantly depleted, but the myth of deforestation in the U.S. is just that, a myth. There hasn't been a significant decrease in plantlife except in very urban areas, like New York.
Also, on a world wide scale, much of the plantlife that handles the CO2 issue is in the ocean. I don't remember the number, but something like 70% of the CO2 converting plants live in the ocean. I think that's the bigger issue.

cows would no longer be slaughtered, but still they'd still be raised commercially
I see this as more of a way of recycling. Crap is a by-product of an animal using energy. The actual energy needed to produce that crap is immense. Think of the grass that has to grow and the nutrients placed into the soil, then what your body can't use is the crap. When it gets down to it... we would probably save money, and resources just growing tress on that land and burning those(skip the cow). The benefit to the current setup is that we can raise the cow, eat em, and then recycle the by-products.
They're getting energy from what was considered to be a waste product. If they weren't doing this, we would have to make larger nuclear power plants, or whatever other form of energy product you feel is acceptable for the environment.
This is a win-win situation, for those involved -- they de-water the waste, compact the waste for easier removal, and get energy back in the process to help offset the operational costs for the process.
For those who didn't take sewage treatment classes in college, there are four main types of setting -- type 1 is for things that accelerate from gravity (sticks, rocks, etc), type 2 is things that floculate (clump together as they're falling), type 3 and 4 are not typically done in a water treatment plant as they don't happen quickly enough. So, what they do is syphon off the 'mostly' clean water at the top, and dump the sludge at the bottom... but the sludge at the bottom is still mostly water, which is heavy, and bulky. Depending on the area, they'll spread it out to dry in the sun, or use anaerobic digestion (such as in the bottom of a pond), to get it to compress further.
And let's not forget that composted manure makes great fertilizer, which the farmer might otherwise be buying for the plants that go into feeding the cow. It's all just an example of a nice little ecosystem.
Build it, and they will come^Hplain.
I read recently that there's enough old growth forest in the US to make a band as wide as texas from NY to Seattle.
Much of it is in undesirable areas (mountains etc) or protected parks so it's pretty much safe.

"With net metering, small producers like Straus can reduce or erase their energy bills but cannot be paid for pumping excess energy into the grid. Net metering has been available to owners of home solar systems for several years."
Why do we allow laws that strip us of potential income, and benefit companies like PG&E?
My ancestors didn't fight for millions of years to get to the top of the food chain for me to be a vegetarian.
Saying Java is nice because it works on all OS's is like saying that anal sex is nice because it works on all genders.
This is yet another reason why we have the "Sonoma Aroma" in Marin / Sonoma County.
You'd think the Sonoma Aroma would smell like wine and vineyards. Nope. It smells like shit.... especially in the summer. Nothing beats endless acres of giant turd piles baking, up wind, in 95 degree temperatures.

See the Green-E website. Many landfills already extract their methane emissions. This is good even from a global-warming perspective, as methane is also a greenhouse gas. Finally, the EPA has tips on reducing methane emissions from livestock themselves, as opposed to their turds.
Can't you see that everyone is buying station wagons?

They still use it as fertilizer. While it's sitting in the lagoon decomposing, they capture the methane (instead of letting it outgas into the atmosphere). Then they take the good stuff out of the lagoon and spread it.
it really just depends. One, you don't have to use manure, you can use a variety of any biomass that will anerobically digest, which is hmm, all of it. One idea I heard of was from jaque cousteau, his was to use kelp, because of it's incredibly fast growing nature and the make-up of kelp makes it ideal for digesting. It seems industrial hemp would be ideal, too, it's cellulose production per acre/year is amazing, and it doesn't require that much fertiliser, you could get by just plowing under 1/2 the plants every year for that, then re apply the slurry as well. If you could see in meat space how much quite useable burnable gas you get from even a small amount you'd see it's very practical and economic. The deal is, the big energy companies CAN'T send you a bill for it,because you can own it, so no way will this be pushed officially by the government or it's controllers, big industry, that much. They *dig* having you pay forever into their monopoly, both with cash and with mindshare. It's the same with solar, with wind generation, etc.
Second,to get back to some farm savings, although the nitrogen level % remains the same in the manure and water slurry after digestion, it is in a more available form to plants than normal aerobic digestion or composting (farmers just shoot this stuff back on the fields now, with conveyor spreaders or flail spreaders). I have read it is as high as 600% better with anerobic digestion, so you get significant savings on fertilizer (which is a HUGE cost now and going up because artificial fertiliser is made from natural gas), which is what's done with the slurry after it has exhausted methane production potential. And last, it is "relatively" cheap to build these things,and they are incredibly scalable, there's a size and technique to fit any size operation, from joe water buffalo rice farmer on up. There are hundreds of thousands of them around the planet now,of various sizes,just not much in the US, so here it's stayed mostly "experimental",and they have to "study it", etc, that's all, any place else it's just normal, and sunlight is an excellent conversion tool for getting solar energy into various useful products. It's very productive sunlight is,a great energy conversion tool, especially with living plants, and it's the only practical fusion generator we have, and it's "free and open source", the government or industry can't charge you for it directly. They will play act at supporting it, that's about it, it doesn't lend itself to monopoly control, so they spread a lot of economic FUD around it.
Remember, farming has always been profitable and useful,well, from obvious reasons, food is kinda nice, even before modern techniques were invented, so it's quite do-able. Look at giant forests, grow all on their own, no high tech anything needed for them to grow, just water, dirt, sunlight, air, done. They are just huge biological manufacturing plants, quite sophisticated really, and that's all any farm is, a biological factory, and there's various ways to cut costs and remain profitable, ONCE you as joe big farmer STOP being brainwashed by monsanto and the energy companies and the equipment companies and the banks. You have to break that mindset of "dependence" first before you can wrap your brane around "how to do it" better. That first step is just too much for most people to get over. It's not really their fault, it's how they were taught, and what the "approved" techniques are as taught at ag colleges and in industry orgs. There are VERY few independent farmers around, the vast majority are really just coporate sub contractors and have to follow these corporation rules. The guy I work for owns three large farms, he is controlled by his suppliers and marketing org down to an obscene picky little level like you wouldn't believe on how to run his farm, or he can't market, and that's the biggest problems farmers have now, and they get trapped into it, go along, or go broke. Once in and in debt, they are trapped, it's almost like a form of serfdom on a large scale. It's a hard
