surely some mighty fine gearing could be created to step up the power

step up the torque, or the speed [mutually exclusive], but not step up the power. it actually decreases the total power output due to friction. however, it would be very beautiful.

The power available is strictly limited to 1hp. (hamster power)

Unless you've got special zero point hamsters who can access the potential of the free energy from the vacuum.
(which doesn't exist.)

Hmm?? Hamsters as Orgone accumulators.
Pass me the crystals. (Sound of high pitched squeaky chanting.)

love to imagine our lady rats enrolled in such an undertaking, although we have a rather large wheel due to the extensive girth of our rather portly lady, she does love to run though

hmm, zero point hamsters... perhaps an inter-universal matter-energy bridge would solve the problem, although are the hamsters skilled in astrophysics?!

Yes, well.

Pan dimensional hamsters may be an amusing side discussion, but it perhaps does not help with the original posters question.

It's far too easy to digress into silliness,(I tend to do it a lot)

But, there is a serious point to be made.

Getting yougsters to understand concepts about energy is vital.

It doesn't just appear from nowhere and figuring out that it needs a source and machines to convert it from one one form to another is fundamental to a rational understanding of the real world.

Sure, lets keep it fun but a bit of real science in the mix is what's needed.

Depends on whether the Pee H is more than seven or less.

From the smell of most Hamster cages I've ever encountered, It's definately less.

(You see , I'm doing it again.)

Yes, I quite agree, pardon my silliness! Actually my friend's son of 9 years was quite excited by the prospect of rodent energy generation when I mentioned it to him ~ perhaps another project in the offing...

A similar project that might be pleasing for a child, and appealling to childhood practicality: Affix the little generator and LED not to a hamster-wheel, but to an old bike drive-gear, and add a very long bike chain, with a heavish weight on one end and a stop on the other. Hang this on the wall next to the light switch by the door. Pull the chain to raise the weight as high as it will go, flick the light-switch off and let go. The falling weight will power the wheel, probably generating enough energy to run a fairly bright LED and lasting just long enough to light your way as you dash across the room and leap into bed.

With a more handsome wheel and chain and the sort of stairwell that allows a free-fall of more than one story it might run the light for a pretty decent length of time and be a fantastically steamy emergency lighting solution, allowing you to carry your mutants up to their cages without having to juggle a lighted candle at the same time.

Shocked I need this.
For a long time now I have been turning my lights off with a wooden sword I keep on the wall by my bed.
But then "how would I see in the dark to replace the sword?" I hear you say, for that I have a tiny little joule theif lamp which is 40% pipe-cleaners and attaches to the shelf near my bed by a clothes peg.

I need a couple of them too, come to think of it. One for just inside the front door, where, if one comes home at night, one must walk about four steps across the room in pitch darkness and feel about on the wall to turn the overhead light on. I'm so used to it I'd forgotten how annoying it used to be. And another, just outside the same door, to light it just long enough to fit my key in the lock, a problem that is still annoying. Feeling around for a chain to pull would be a much simpler operation than trying to fit the key blind, and I never remember to waste electricity by turning the porch light on before I leave.

You can buy dynamo lights for your bike that works by putting some magnets on the side of your wheel. I´m sure that could be modified for a hamster wheel.

Hmm... well, if you know the diameter of the wheel and the weight of the hamster, you could calculate the maximum torque the contraption could produce. If you know the maximum speed of the hamster, you can work out the maximum rotational speed of the hamster wheel. The torque figure and the speed rating together could then form the basis of your horsepower calculation, which then in turn is easily converted into Watts..

Which brings up the question as to how much hamsterpower is a horsepower.  (x hP = 1 HP)

This obviously means that I require 1000 hamsters for my horseless carriage.  Horseless, mind you, not that infernal ICE.

what's the technical term for this type of generator? it escapes me at the moment  Undecided
and now this thread has me thinking of ways to power my new lantern using the same concept but using the gears in a small clock movement.

the lantern I made can be seen here if anyone cares to have a look

if you consider the wheel diameter proportional to the animals length, how many horsepower would a horse generate, in a giant wheel?

i dont know the length of a horse, nor the one of a hamster, to calculate the size ratio for the wheel size, nor do i know the average speed of a horse, that he can maintain for quite some time.... the weight is equally unknown to me.... i'll happily do the math, if someone can provide me the numbers. as much as i like horses, i am an urban person, and the horses are scarce in my city.... so taking measures is out of question

I think everyone is forgetting to calculate the sheer WILL of the hamster!!! *raises fist to the sky*
*drops fist down suddenly* because if you have a lazy hamster no amount of math can predict the outcome.

realistically you'll only generate as much energy as your hamster feels like generating. doesn't mater how elaborate the gear drive or optimized the device is (although it certainly will help) if the hamster doesn't want to run, he wont.

One for just inside the front door, where, if one comes home at night, one must walk about four steps across the room in pitch darkness and feel about on the wall to turn the overhead light on.



A few years ago I attached a motion detector device, supposedly for use outdoors, to a low wattage light in my kitchen.
http://www.brasswings.com/images_misc/motionlight.jpg
Now, when I get up in the middle of the night to get a glass of water or a snack, a lovely dim non-blinding light illuminates the way for me automatically, and kindly also turns itself off a few minutes later.
Looks like you need one for the hallway.
