I'd prefer to hook my spin trainer up to the grid ....
Nukes vs Coal, protests about wind turbines(!) ... I want to hook my fluid II up to the grid and get back some of my watts! |

Dammit... now you've got me thinking... hmm... one grid feed inverter, one dynamo, presumably some kind o AC/DC convertor thingamyjig... assume a price around 5c/kwH (residential rates are around 10c an assume they'd buy it bake at 'screw-you' rates). we'll be optimisti and assume that if we're 'training' we could churn out 15 watts/hour... hmm... barely 1 cent an hour... gonna take a while to pay off tha inverter! bugger.. -- eddiec |

Given the roughly 20% efficiency of the metabolic process, for that ~300w at the flywheel, you can also get at the remaining 80% (~1200w) that's given off as heat with some form of heat exchanger. So, if it's winter, you're not only contributing enough wattage to run the PC that you're hooking the HRM up to, but you're heating the house, saving the need to burn precious fossil fuels. Or, you could rig up a heat exchanger and use it to generate power, probably from bits found in Hip's shed and the dumpster across the road from Dutchy's office. A win, I think. Of course, to maximise efficiency, it would have to be a SS, as we all know that the weight savings and frictional losses in jockeywheels and cassettes are of such a significant magnitude as to completely overwhelm the issue of cadence and efficiency. YMMV ... |

(and i think they all do net metering, some even used to pay up to 4 times more for "green" power, not sure if this still goes on) now if i could find 100 spare hours in the day for pedaling, i would beak even(not including the gas for water and heater). still finding 100 hours in the day seems easy compered to getting a reactor built |

If you are on a trainer, inside, during winter.. you wont NEED heating! Yay for $aving million$ in fuel cost$! hippy |

was almost, but not quite, entirely unlike tea: Nukes vs Coal, protests about wind turbines(!) ... I want to hook my fluid II up to the grid and get back some of my watts! I wish bikes had regenerative braking. Then those stupid traffic lights at the bottom of valleys would be no problem. Just spin your flywheel up to 200000 RPM (and make sure you don't turn any corners!), stop, wait, then spin it back down. Easy! -- TimC -- http://astronomy.swin.edu.au/staff/tconnors/ Oooh, Look!

I was just this morning dreaming up a lighting system with a wind generator built in to regenerate the batteries. It made sense to me, because the forward motion of the bike will always produce air movement to spin the turbine. Brilliant, a foolproof plan! If only I was an engineer! Bjay |

Just be careful how you connect that thing up. Make sure it doesn't become an electric motor and take off down the road with you on it! Marty |
