I posted this last week on some horse sites and got some
good advice. I was wondering if a treadmill could be used to power a wagon and a horse could be made to operate the treadmill. I have since found out that horses operated stationary treadmills for powering machines and ferryboats, but that was almost 200 years ago. I'm wondering if the technology could be developed that would enable an ordinary horse and rider to beat Lance Armstrong and/or Smarty Jones. (I'm thinking 100 relatively flat miles at 35 mph would be a good goal, better than anything possible by a bicyclist or horse and rider.) Basic data, a horse weighs around 1000 pounds and can generate up to 3 horsepower in short bursts. Treadmill would probably have to be around 10-12 feet long, would need some sort of automatic transmission to keep the horse operating at it's best speed and keep it from falling off either end on a hilly road. On a more practical level, if there are some of you who DON'T think it would be worthwhile to do this just to see if it could be done, this could magnify the output of a horse just as a bike magnifies the output of a human, and in parts of the world where animal power is still used, it could make peoples' lives better. I don't own horses, don't know how to weld, don't have any money. Anybody thinks this is a cool idea, give it a shot and let me know if it works. There are lots of challenges, both ergonomic and engineering. |

Won't work for two reasons that I can think of. 1. too much weight for the apparatus; 2. four-footed animals use not only their four feet, but also their midsection at the gallop, which functions like an additional leg or similar. The mid section contracts and extends adding a lot to the power and it would be difficult to transfer this power to a treadmill, IMO; 3. lack of proper fit and friction to transfer as much power from the horse's feet to the treadmill. OK, that's three reasons... ;-p -Badger Oh, and you'd have to change horses well before 100 miles. I think the pony express riders changed up at like 30 miles or 50 miles, IIRC. |

I think it could work, but don't think you'd get 35 mph out of it for any length of time. Do some of the math, and figure out how much power it would take to move 1200 lbs at 35 mph over a typical road, and then compare that to how much power a horse can put out for 3 hours. I don't think those numbers will be consistent with each other. Consider a bicycle: a top human sprinter (Cipo, etc) can put out a little over 2 hp for a few seconds, and that gets him up to around 50 mph, with a total weight of bike and rider of less than 200 lb. I don't think you'll get a horse and carriage to 35 for very long, even without carrying any useful payload. -- Remove the ns_ from if replying by e-mail (but keep posts in the newsgroups if possible). |

But a horse, developing full power (picture a horse at full gallop) would be out of contact with the treadmill a lot of the time. So, to keep him from running off the front of the system, you would have to tether him, and he would end up pulling on a harness. That is what draft horses already do, except they push against the ground. I believe that is the most efficient method of drawing power from a horse. And, I believe a rider on the back of a horse would be using the horsepower more efficiently than any contrivance you could rig up. A rider at full gallop could surely beat Lance Armstrong. |

Secretariat's time in the Belmont was 2:24 for 1.5 miles, which is about 37.5 miles per hour. (He won by 31 lengths, and it's one of those records that may stand for a long time.) But even Secretariat couldn't maintain anywhere near that pace for many miles. |

But the ground/treadmill is still the only thing against which the horse can push. The force doesn't go anywhere else. >So, to keep him from running off the front of the system, >you would have to tether him, and he would end up pulling >on a harness. Or use an incline to offset the resistance of the system, but I suspect that if you rigged such a device you'd want a harness anyway. --kyler |

The horse has evolved to cover long distances efficiently. It's one of the most efficent animals on land. Anything you do to change it's energy transfer system only detracts from the horses performance. Marty |

Little arows so they know which way to run. And maybe a whip. Curtis L. Russell Odenton, MD (USA) Just someone on two wheels... |

A horse on a running on a treadmill is using the exact same motion as a horse running on the ground. All the treadmill and wagon can do is add friction and slow down the horse. The reason a bicycle is more efficient than running is that the weight is supported and the power is transferred directly to the wheels. If you could design a wheeled contraption to support the horses weight and let it transfer power directly to the wheels, you would have something that would go very well. Also people would pay to see it ![]() Jeff |

Actually using bad or no physics, I fsked up, and now I'm trying to do damage control. It might have been I wasn't awake yet. Yeah that's it. ;-p -Badger |
