I was really bored so i thought I'd calculate how many hamsters it would take to power a house and how much it would cost.

The average hamster weighs about 4oz, runs at an average speed of about 1.2mph and runs about 8 miles each night. If he were to run in an 8" diameter wheel he would produce about
1oz-inch of torque (4oz at 4" radius) at 50.4202860rpm (8" X pi = 25.1327412". 63360"[one mile] divided by 25.1327412"= 2521.0143014 rotations per mile. 2521.0143014 X 1.2 = 3025.2171617 rotations per hour divide by 60 = 50.4202860 rpm).1oz-in. = 0.0052083lb-ft X 50rpm divided by 5252 = 0.0000496 HP = 0.0369867136 watts.

So, the average hamster generates 0.0102741watt (0.0369867136 X 6.6666667 [8hrs/1.2mph] divided by 24). The average household uses about 2900Watts which means it would take 282263.1666034 hamsters to power the average household.

Each day the average hamster drinks about 25cc of water and eats 12 grams of food. A 2lb bag of hamster food costs about $5 and a gallon of tap water is about $0.001 so it would cost about $0.0055118 a day per hamster which would be $536.48 per kilowatt hour. (1000 divided by 0.0102741 = 97332.126415 X 0.0055118 = 536.4752144)

Could you kindly recalculate this for the
following animals: weasels, dormice,
guinea pigs, centipedes, dachshunds...
Let
me know when you have the results.
Graphs would also be helpful. ps
Welcome to the world of halfbaked
ideas.

How much thermal energy would so many hamsters generate? Could this be used to directly heat a house? Could you attach a stirling engine to the room they were in?
