is there something out there that you can get to hook up to a stationary bike

with pulleys to produce some.... electricty while you are peddling to run something small i.e. tv or radio

Interesting McG.....

I've often thought about all the wasted power I've pumped into my trainer over the years.

If I were to do this, I'd set it up to charge a battery, and use that to drive TV or 'puter. The voltage fluctuations of even a relatively steady ride aren't real good for sensitive electronics.

here is one that is on a trainer:

Here are plans to build your own trainer style:

This guy made a "sort of" exercise bike back in 1976 to make inverted 110V.

When I were lad, I hadda thing on backo me bike, called a dynamo. Takes motive force from the rear wheel, used it tu generate elec. for lights....

To build @ home, all y'all need is copper wire, an magnets. Basic physics. Pass a wire thru a magnetic field, in generates a charge. same vice-versa. Spin four magnets attatched round a spindle - centered within a coil of copper wire... instant electric. Although, strength o magnets, No. of coils & RPM of magnets will all alter current.

And a T.V. useually doesn't count as 'somthing small' as it almost certainly features on the list of 'high drain home appliances'
