Cows On Treadmills Produce Clean Power For Farms 640

Posted by CmdrTaco
from the mooves-you-to-tears dept.
separsons writes "William Taylor, a farmer in Northern Ireland, recently developed the Livestock Power Mill, a treadmill for cows. Taylor uses the device to generate clean, renewable power for his farm. Cows are locked into a pen on top of a non-powered, inclined belt. The cows' walking turns the belt, which spins a gearbox to drive a generator. One cow can produce about two kilowatts of electricity, enough energy to power four milking machines. It may seem like a kooky idea, but Taylor could be onto something: According to his calculations, if the world's 1.3 billion cattle used treadmills for eight hours a day, they could provide six percent of the world's power!"

        Apparently you've never watched cows grazing out in an open field. They do move around, but only enough to get fresh grass between their lips. They don't trot from one end of the field to the other. They mow a bit, take a step, mow a bit, take a step. Sure, they do end up going a fair distance over time, but nothing like being forced to walk a treadmill.

              I was about to say, I pay $2 to $4 a bag for that stuff to put on my blueberries, blackberries, etc. Better yet: use human waste for lawns, fields and golf courses.

              We cleared off 1/4 acre of wood (which was taken to the lumber mill and turned into railroad ties) and in order to get grass to grow in the poor soil, we hauled in a tandem load (about 11 cubic yards or about 9-10 cubic meters) of "sterilized compost" from the waste treatment plant. This means grass clippings, leaves and human poo, sterilized and composted, all "trash" that the county has to deal with. It costs $110, delivered, and we spread by hand. Best. Lawn. Ever. And no, it doesn't smell like poo, just a little like ammonia (like all compost) for a couple of days.

              I'm a conservative who is a conservationist (ie: I have no use for environmentalists as I want to USE the resources we protect) and this is the right way to recycle and reuse, as it gives great results, cheaper, and creates less landfill, which is where it would have gone if I didn't spread it on the lawn. AND it allowed the waste plant to make a profit on something they normally would have to pay to dispose of.

              There's this *really* cool thing called a free market economy that prevents bozos from implementing cockamamie schemes that don't create any economic value. Then we go and do stupid shit like subsidizing corn production to fuck up these economics. I'm not an absolutist, but when it comes to energy production technologies, we really should just let the market sort it out, and abolish the corn subsidies.

              Things that make no sense in terms of net energy production will inherently be money-losing ventures in the absence of state intervention. So we won't have to listen to people whining about how bioethanol is inherently a net energy-wasting fuel (gee, if it is, and it produces no economic value otherwise, it will be a money losing venture and nobody will make it).

              Beyond that research funding and venture capital investment should finance the technologies that are actually capable of producing net energy, rather than those that have figured out how to game the system of subsidies best.

            How many generations are you separated from the farm Ellie??

            Don't bother answering that, it's retorical. Animal production farms are always associated with crop production farms where the manure is spread on fields as fertilizer. Landfills are full of trash, not animal waste (unless you count cat and dog feces).

            We don't feed 75% of our grain production to ruminants. We don't even feed 75% of our grain production to livestock (which includes pigs and poultry). According to the USDA [], nearly a third (~ 4.25 billion bushels) of domestic corn production is expected to be used for ethanol in 2009/10. In the same season, ~5 billion bushels (~45%) will be used for "Feed and residual uses" which includes both human consumption and livestock use, and another ~2 billion bushels will be exported.

            As to the original topic, putting cows on treadmills, I don't see it being feasible. Cows are rough on equipment, so the treadmills would need to be very robust. Cow manure is very corrosive, so they'd either have to use expensive equipment that is durable, or have a high rate of failure of various parts. I do have to admit though, that cows do a fair amount of walking in free stall barns, but I just don't see how you'd get them to use the treadmills instead of walking up and down the isles as they do now. IMO, it's a case of something being technically plausible, but ultimately unfeasible.

            Definitely an intriguing idea though. I'd be interested to see if they could do something similar with an animal that is raised in a more confined environment, like a gestating sow. It would require that she get more food, but her appetite already oustrips what she's allowed to eat so that's not an issue (whereas dairy farmers don't want their cows to be wasting any of the energy that could be going into milk production, and the cows are already offered ad libitum feed). It would come down to whether the electricity a sow could generate would save the farmer more money over the increased feed, equipment, and management costs.

            Why we insist on feeding 75% of our grain production to ruminants baffles me.

            For beef cattle, we do it because they bulk up faster on grain than on grass. It is possible to buy range-fed beef, though if I recall it is substantially more expensive. The rancher is a business man and he makes better profits feeding grain to his cattle to get them ready for slaughter. This in turn enables him to sustain his (usually modest) livelihood and enable the consumer to afford beef as a staple rather than as a luxury. If all beef were range-fed then the economics of beef production would be totally different.

            For dairy cattle, they are often range-fed in my region (New England) but due to freezing temperatures cattle have to be fed on silage in the winter. Otherwise they'd stop producing milk and we'd either have to import milk from outside the region, or go without.

            So, we feed 75% of our grain production to cattle so we can have readily available beef and milk. Why we think we need so much beef is another question, and one that does make me scratch my head a little.

              We eat beef primarily because they will stand in a feedlot and chew cud instead of breaking down fences or harming each other trying to escape, like Bison. Unfortunately, this feedlot approach results in sick animals, period, the end. So we treat the animals with antibiotics. The cattle can't move around so they don't develop any muscle tone. The result is insipid and often unsafe beef. Sure, it costs more to buy grass-fed, free-range beef, but the quality is superior in every way. Meanwhile, I'm buying buffalo meat at comparable prices; you can't put them in a feedlot, so all of them are grass fed. Actually, there is a movement today towards native grasses, at least in this country; native grasses don't ever need to be fed because they grow in what a permaculturist would call a guild, with each plant providing for its fellows. Some grasses anchor soil, some fix nitrogen, and some send deep tap roots to mine the lower parts of the soil for minerals. This native grass will support nearly any kind of animal; the "improved" grasses commonly planted for animal grazing tend to be species-specific. For instance, the pasture mejorado being planted in Panama causes increased beef production in the cows, but a horse will starve in the field. And more importantly for the beef, it produces a lower quality of meat with reduced flavor and texture as compared to the native grasses. So ranchers who are aiming for quality rather than quantity are very much replanting their ranges in native grass.

              So, we feed 75% of our grain production to cattle so we can have readily available beef and milk. Why we think we need so much beef is another question, and one that does make me scratch my head a little.

              Beef is delicious. The real question is why we need so much milk. Milk subsidies in the USA led to the production of milk hormones to increase their production... or was it the other way around? Thanks, Monsanto. Regardless, we produce so much milk that we have to invent new ways to get rid of it, which is why we got all that Recaldent-brand gum which is made from milk. It would be nice if we could get some milk paints out of it, so we could use less of the toxic bullshit housepaint that we tend to use, but I guess the chemical lobby would put a quick stop to that. The really sad part is that the rest of the world is less than interested in hormone-infested milk (rBGH has been proven to increase udder infections which means that milk with rBGH also has increased levels of both antibiotics and pus from infections in it... I like my milk with extra pus, how about you?) so the only place we can get rid of it internationally is those parachuted milk powder bombs that we keep dropping on the third world.

              Ending all food subsidies would be a very good way to improve the quality of food production in the USA, not to mention, it would enable the free market to provide us with more logical foodstuffs.

Furthermore, there is no different in fat content, protein content, etc.

          Correction # 1:
          Cattle are not as sedentary as you may believe. Range raised beef cattle walk between 2.8 and 4 kilometers/day according to a 1991 study published the Journal of Animal Science []. This means they are already doing a lot of walking. The real question is whether we can capture that energy they are already spending, and turn it into electricity at a price that is acceptable. (I doubt that they can, but I could be wrong)

          Correction # 2:
          Exercise does not increase "stress byproduct" concentrations (what every that's supposed to mean), unless the exercise in forced. As I mentioned before, the animals already do a fair amount of walking on their own initiative. In that case the actions taken to force the exercize would be causing the stress, not the exercise itself.

          Correction # 3:
          It is the intramuscular fat that is responsible for the great taste. Backfat is often cut off by consumers and not eaten due to texture issues, and sometime for cooking issues. Kobe beef is completely unlike anything raised for the general consumer market, so trying to draw conclusions based on that niche market is inadvisable.

    There are two glaring faults with this setup:

    #1) The cows are 'locked in'.
    #2) The treadmill is inclined.

    This results in the animal walking out of 'fear' from falling. The inability of the animal to stop whenever it wants is cruel treatment. On the other hand, if it were 'elective' and the cows got a special treat (a yummy grass/feed?) then it is a different story.

    I would like to see how guy would like to be locked onto a treadmill 8hrs a day, walking uphill the entire time.

    I doubt the quality of the milk would be very good. Stress does not make for a nice quality or quantity of milk. (I used to work on a dairy farm.)

    Funny and innovative as the idea is: I wonder how clean this energy really is. It doesn't come out of thin air, those cows have to eat. And a cow's digestive system tends to produce quite some methane (a major greenhouse gas), and quite some waste - which also releases lots of ammonia amongst other harmful chemicals. On top of that the fodder also has to be produced (often using power for machinery and so), and a cow that walks that much definitely eats a lot more than a cow that grazes the pasture or is kept in a stable without much room to move.

    And besides I think there are much more cattle-friendly ways to exercise your cow.

  • I was a little concerned over the treatment of the cows but the guy doing it made an interesting point:

    It may seem cruel to make cows sweat it out on a treadmill, but the routine is actually quite similar to the animals' normal behavior. Cows walk about eight hours a day while grazing. Doing that walking on a treadmill provides the same amount of exercise with the added bonus of renewable power production.

    Also, after thinking about it, I can't think that this is any worse than making them stand shoulder t

  • Wake me up when they come with their own mounted systems for bovine freedom.

    I think they might want to take this technology to Southeast Asia... elephants are not only much more massive but also seem much more active, and the elephant conservatories in Thailand are always looking for things to do to make money to afford to keep their brood occupied and healthy. /drove through Wisconsin last week, saw mounted cows.

    How do the Hindus feel about their ancestors being forced into manual labor like this, when they could have used human beings instead? And how does the cost of buying and maintaining a cow treadmill compare to the cost of a solar power array that would generate 2 kilowatts without the constant trouble of cleaning all the cow shit off of it? Cows are one of the least efficient animals at turning grain into meat; I suspect they are also grossly inefficient at turning grain into power. If you take that same grain, ferment it, distill it, and use it to power an engine, how much more or less power output would you get?
  • The next logical step is to install these at MacDonalds.

  • It'll be even better when PETA finds out about this.

    Put cow in tiny box which is sloped so they keep walking up hill, shove food in its face, hook the belt they are turning while walking up hill to a generator which in turn powers the milking machine that is hooked to the cow's udders.

    They milk themselves, while being put on a forced march.

    That should generate entertainment in the form of PETA ravings.

    In Lincoln's New Salem, near Springfield, Illinois, there is a reconstructed carding mill [] powered by a tilted tread wheel on which an ox walked to supply the power. This would have been in use around 1830.

    Some people have joked about methane, but for those concerned about greenhouse gases, this would probably be worse than burning coal. Methane from livestock is a major source of greenhouse gases, to the point where one's personal impact on greenhouse gases is greater from giving up animal products than giving up one's car.

      Methane has indeed a high global warming potential compared to CO2, however that calculation misses one important fact. And that is that methane has a rather limited limited lifetime in the atmosphere, around 12 years. After that it breaks down and to a large degree it goes back into circulation, becoming new methane eventually.

      When you burn oil you release CO2 that has a life cycle of (conservatively) tens of thousands of years.

      This means that if you kill off all cows and other methane production today you will see the methane effect start to wean after about a decade. Stop burning coal today and the effects will last longer than civilization has existed. As we are speaking of additive effects on the climate you quickly realize that you probably should be much more worried about the gases with long lifetimes and/or high GWP (CO2, HFC-23, SF6 etc) and less about those gases with short lifetimes/low GWP.

  • why doesn't the `Y' hook it's treadmills up to generators? I have seen fat cows walking on them all day - the energy they produce is just lost as waste heat. It would be far better to redirect it into the grid.

  • As a side effect, you could get better tasting meat. Where does meat gets it taste from> From the blood and the more blood, the more taste. Moving will increase the blood flow and thus the taste. The downside is that meat won't be as tender anymore and in todays world tender is more important then taste.

    What the effect is if these are milking cows (which I assume, as they are talking about milking machines), I have no idea. Will the production and/or quality be the same, higher or lower?

    Have you ever seen a field or corn, wheat or strawberries? Those plants are packed in tight. This is completely opposite to how plants grow in the wild. It's so cruel that we force these plants to grow in tight, geometric formations, never able to get proper air circulation, we force grow them in pots which is never found in the wild and in densities never intended to by our mother, earth.

    Seriously, I'm not a PETA-type person at all, and even I think this is kind of a cruel thing to do to animals, even if it's cows we're talking about. Granted, they're not in the least bit bright, but we already use them for milk and eventually kill them for their meat and hide, it seems rather heartless to make them generate power as well.
  • The article should have gotten Gary Larson (Far Side) to illustrate the concept. I picture the Cow standing on hind legs running on a treadmill at the gym with an ipod and watching Oprah.
