His grandpa would have called it waste. He called it hundreds of thousands of dollars a year. |

Revealing ignorance of the cattle industry in 3...2...1... Are they fed something different, which is better for fuel? Does it have to do with how old the cows are? Perhaps dairy cows get to live longer, or cows must reach a certain age to, ahem, produce fuel properly? Or does it have to do with how much energy the farm requires? What type of energy? Would the manure be supplying power to the milking machines? |

However, keep in mind that this energy source only works for "him" (I can't believe we haven't named him yet. How about Greg?). It would not have worked for Greg's grandfather -- even if the energy-harnessing technology had been available at the time. |

Machinery that didn't exist on grandpa's time relevant? yes Technology? and yes Ok, NOW the crux of the original puzzle is solved. The farmer (Greg) has machinery that collects manure, collects the methane gas that it products, and heats it to turn a turbine that generates electricity. He saves hundreds of thousands of dollars a year by producing his own electricity this way. This machinery/technology did not exist when his grandfather was alive. Now, my secondary question remains...why does this scenario specify dairy cows? |

Because he runs the milking machines with this electricity? irrel And in Grandpa's time they had not been invented, and so they would've had to hand-milk the cows yes even with all the free electricity? irrel I think a RECAP of the dairy cow related posts is in order: As you have established, Greg collects cow manure from his dairy farm and uses it to generate electricity. My question for you is why this system makes sense on a dairy farm but not on, say, a beef cattle farm. The following are irrelevant: - The suitability of the cows' food source for making fuel. - The age of the cows - The amount of energy the farm requires (though you are correct that Greg's farm would require more electricity than his grandfather's farm) - The type of energy the farm requires - What the power is used for - Government regulations - How the milk is marketed ("organic") What IS relevant: - the mechanical milking process, but NOT because it uses electricity - no one in the grandfather's time would have been able to do what Greg does, even if the technology for making electricity out of manure had existed. On the right track: Dairy cows have to be brought to a specific location each day to be milked (making it easier to collect the manure) whereas beef cattle do not. Come to think of it, this is actually more than just ORT, it's actually half of the answer. Now, why would this work for Greg's modern dairy cows, but not his grandfather's? If you can figure this out, then you'll figure out the other half of why this system works for dairy cows. |

Would this method work for goats that are milked, assuming you could use goat waste as fuel? Would it work with pigs, which I understand produce a heckuva lot more waste than cows? So there are two reasons for the success of the process -- reason 1 is that milk cows are milked at a specific place, whereas beef cattle presumably are scattered all over the prairie. Would this method work on beef cattle in the stereotypical non-PC factory farm where they never leave their stalls? Is it easier to herd cows today? Or to simply keep them in place, given new methods of keeping them healthy without normal exercise? |

I would think it would be possible for both, if you presume that they're handled the same way as dairy cows are. So there are two reasons for the success of the process /b{not exactly. There's one reason. Half of that reason is that cows are milked at a specific place. The other half of that reason relates to what makes this work for Greg but not his grandfather. But it's really just one reason.

HINT/RECAP: Greg is a dairy farmer who collects manure from his dairy cows and turns it into electricity. His grandfather was also a dairy farmer. However, even if the technology Greg uses to generate electricity had existed then, Grandpa still wouldn't have been able to do it. Why? The reason that this works for dairy farmers but not other cows has something to do with the cows being brought to a central location to be milked (making manure easier to collect?), but that is not the whole answer. The whole answer lies in the comparison between Greg and Grandpa. What Greg and Grandpa have in COMMON: - Both dairy cattle farmers - Both milk their cows in a central location (barn) What is DIFFERENT between Greg and Grandpa: - Grandpa - milk by hand; Greg - mechanical milking - Grandpa - all cows milked at roughly same time of day; Greg - cows milked throughout day - Because of the differences above, something important is different about the way the cows are fed (HINT: *where* is relevant) - (Greg also would have a much larger herd, due to mechanical milking, but this is irrelevant) |

Are the cows fed in Greg's milking stalls? /b{yes!! (well, the barn doens't have individual stalls, but yes)} Did Grandpa feed the cows out in the field? /b{yes} How to ask this delicately...Do dairy cows typically eat and defecate at the same time? Or within a short time before or after eating? no to both, and that's actually important(Ick...do I even want to know that answer?) I could draw this out and have you tell me why they do it that way, but I don't think it's necessary, so... *****SPOILER****** *Original puzzle:* Greg collects manure from his dairy cows and uses it to generate electricity. He has a special machine that heats the manure, collects the methane it releases, and uses the methane to turn an electricity generating turbine. He saves $200,000 a year on electricity -- partly from not having to buy electricity from the public utility, and partly because he generates so much extra electricity that he is able to sell it. In addition to his farm, 12 neighboring houses are powered by his electricity. Based on this article: http://www.cnn.com/2009/TECH/07/31/cow.power/index.html (includes a video if you want to see how they collect it) ******SPOILER, FOLLOWUP QUESTION********* The question was why this had to be dairy cows. Dairy cows are brought to a central location to be milked, making the manure easier to collect. However, who's to say that they're going to defecate while they're at the milking barn? In Grandpa's day, the cows would have been collected up all at once, milked by hand at a certain time of day, and then turned loose back into the field to eat, so collecting the manure for this purpose wouldn't have been feasible. However, today's dairy cattle are milked by machine. This allows for a much larger herd, but they can't all be milked at once, so they are milked in shifts throughout the day. Because of this, they eat, sleep, and get milked in the dairy barn. Most modern dairy cows spend almost their entire lives standing on a concrete floor in the dairy barn. That creates a manure disposal problem that dairy farmers have to deal with, but the kind of system featured in this puzzle turns the manure disposal problem into a huge advantage.
