How much torque?

Pasqualle could hardly hide his joy when he received the quote award for his lowest-cost transmission testing service. The award letter came with some questions, though. And it seemed the transmission manufacturer was going to send out a representative to get them answered. Where was his estimate for the heightened cost of gasoline? And what was this line item listing out pellet food?
Not a problem. Pasqualle had been expecting this.

The week before the rep arrived, Pasqualle cleaned out the 1000 cages, changed their water, and oiled the ultra-wide 5 hamster wheels, bearings, cogs, and sprockets. Even the third and fourth shift hamsters were antsy to get going.

Needless to say, the transmission engineer was more than impressed to see the collective torque of 5000 hamsters grinding cornmeal and running generators through the means of selective output shafts. Pasqualle released the clutch, changed output shafts, and the transmission test chamber came alive...

It takes about 500,000 hamsterpower to power a home. http://www.todayifo...cheaper-coal-power/

130 ft-lbs, eh? Not quite enough. The engine I've got to deal with is rated at a peak of 325, and I need to test to failure, with some capacity to run up to 400 or so. Sounds like Pasqualle's pellet food bill is going to break his budget.

you haven't factored in the rate at which hamsters cannibalize eachother.

I'd love to see a brake specific pellet consumption curve.

Mmmmmmm...Hamsters.

OK [Voice] [rolls up sleeves] lets have a look at that links assertions, you'll have to bear with me, not going to be quick.

//An average American household uses // 3240 megajoules// a month .. let's say 30 days a month, 24 hours a day, 60 minutes an hour, 60 seconds a minute.

So, 3240/((30*24)*(60*60)) = an average of 0.00125 megajoules a second, so 1250 joules a second then.

A hamster produces //0.5 joules per second// according to the link.

So by the links own numbers (if not it its math) 2500 hamsters are adequate to run a home, multiply that by 20 to allow for the links claim that only 5% of a hamsters time is spent running on its wheel gives us 50,000 hamsters to run a home.

So not 500,000 then?

Either my math is wrong or I'm not impressed with that site .. you wouldn't care to check my working would you?

A hamster generates .5 joules per second (not counting conversion and storage losses) while running, but only runs 5% of the time. That's .025 joules per hamster per second. Looks like someone is off by a factor of 10.

//thus, instead of around 15.77 Megajoules per year, we can reasonably expect about 0.8 Megajoules per year per hamster//

Yep, built that into mine, not sure I didn't miss anything else though, that sites not very concise, it's a bit all over the place, and coming from me that's either saying something (aka a pretty damning observation) or somewhat glass house depending on how you want to look at it.

As I said //So // 2500 hamsters // multiply that by 20 to allow for the links claim that only 5% of a hamsters time is spent running // gives us 50,000 hamsters//

I didn't say YOU are off by a factor of 10. And I apologize for missing your multiplication by 20. I would call it at 50 kilohamsters but I'm tipsy and therefore not confident in even basic math.

I prefer 0.05 MH, if only to insert the term "mega hamster" into the conversation.

At least it's not mecha hamster
