Can a Nordic Trak become a Generator???greenspun.com : LUSENET : TimeBomb 2000 (Y2000) : One Thread
I know this will sound ludicrous, but...
I saw a thread on Gary North's site about possibly rigging an exercise bike up to generate power, such as to charge batteries, etc.
The responses talked about getting a car alternator for the job. I know there are many very bright and resourceful people who frequent this forum, so I wanted to know what you folks thought about the idea.
I know, of course, that lil' ol' me couldn't generate more than a pittance of power, but I do use my Nordic Trak everyday, for a minimum of 30 minutes (no I am NOT either lying!!!) and it seems like I should be able to capture some of that energy and put it to use. If nothing else, maybe I could recharge the batteries in my walk-man?
Is this a completely stupid idea?
Pop quiz: If I 'ski' for 30 minutes at an average speed of 5 mph with a low-medium tension setting, how long do you suppose it would take me to recharge a 12-volt marine battery? (We have one connected to our pellet stove as a battery back-up.)
Boy, wouldn't that be keen? And if it would work with a Nordic Trak, maybe I could do it with the tread mill, too, and take the dog for a walk at the same time!!! Okay, maybe not.
Any thoughts? I mean aside from suppositions about my mental stability...

Yup, you can do it.......are you sure you want to?
Answer to ur pop quiz -- Assume that you need a total charge of 75 amp-hrs for your battery. Superwoman can do it in about an hour. If you're more normal than superwoman you can probably charge the battery in about 6 hours.
But, if you're going to ski on the darned thing for 6 hours you won't need any more heat in the house.
 Truck generator will put out 75 amps, so will recharge the battery in an hour.  Assuming that you can generate about 1/3 horsepower, this equals about 250 watts, or 12.5 amps. You'll need to charge 75/12.5 hours = 6 hours.
Have at it, Debbie. You'll stay slim and have great leg muscles when (if)we recover from Y2K.

I certainly can't answer your question but, I think that q's like that are excellent.....Thought provoking in that they sometimes lead the way to thinking of other untraditional methods of doing "things".
