Hello Sailing Friends,
I have to maintain cardio fitness, I mean I have a slightly defective heart valve, in my 60's that is no threat as long as I maintain cardio fitness.. Anyway, for twenty years I have thought that a 10-20 speed stainless bike to charge batteries would be cool.
Now that I have a cat with huge amounts of room with the Helia 44, is it a possibility.. ?
Like maybe with a DC permanent magnet motor
, or better yet with an alternator
with a regulator
bypass to a variable potentiometer that you could dial up the charge on... ?? Before I re-invent the wheel here, I am just wondering if any of you have seen such a production model?
It is not so much about power..
Yes, I have solar
, plus portable solar
, and a 9.5 kva Cummins Onan. And yes I am up with wind
generators, I have had them before.. A bit noisy at times.. This is for when at anchor...
I will have no power problems for maybe 30 days in summer when it is so hot I will run the genset a few hours at night to get to sleep in a hot spell.. (I cannot sleep if over 30 C or so..) Maybe about 30 days in winter it will be nice to run the genset a few hours a night for heat as my multiple Cruiseaire units are salt water
condensed reverse cycle. The rest of the year though, I will be trying to run as much on solar as possible and this could be a little boost. I mean my workout on it for 45 min- hour, my Wife, maybe my Daughter or guests?? That plus the solar might supplement the power for my three refrigeration
systems.. This would be cardio exercise with a purpose... ??
So, really not for the power,
more for the cardio-vascular work when cruising, with a purpose...
But 10-20 amps or more might make it worthwhile...
Look Friends, if you can show me it is just crazy, fine.
I do not remember my engineering math enough to calculate the horsepower for say 10-20 amps at 14 volts, gear
drive down with say maybe a 20 speed bike drive or if it is even possible. Something tells me it would be too much torque, but then I was thinking get it going on a low gear
and then step it up changing gears???? ...
Tell me I am nuts and I can forget about it forever... That or tell me if you have seen one OK?
Anyone can have this idea if it works and could go into production.. I will be job one.. heh he..
