Battery Recharging


ttrepasso
 

Has anyone done any experimenting on battery
recharging using a system other than solar or a gas engine
hooked up to an alternator? When a kid in the 50's I had
a small generator that attached to the frame of my
bike and turned by rubbing against my front tire
producing electricity to power my headlight. It seems to
me, something like that could be rigged up to
recharge a battery much like that of an alternator on an
auto???????? Terry

I am far from an expert, but the only motor that
I have found that would regenerate, that is
recharge the batteries as the prop turns due to sail power
moving the boat, is the Electric Wheel by Solomon
Technologies. The only caveat is that it will only regen at a
speed of 4MPH or greater. But this is readily
attainable in pretty much any sailboat with a decent wind.

Thank you, Bill, I'll look into it. I assume this
is the same Electric Wheel that's been mentioned
several times here recently. Haven't had time to read
everything. Don't happen to have an address or website to go
along with this information, do you? Terry

1) I'm expecting some material,prices etc. for
the electric wheel, hopefully soon. I have spoken
with someone, who actually took a trip with the owner
on his sailboat, outfitted with the motor. He got so
impressed, that he decided to invest in the comp!<br>The
sailboat used for the trial run was 30-32' old
(and=heavy), and the reports was rather impressive. Lots of
details missing : how much battery storage, price, etc.
<br>I'll be back when I know some more details.<br>2)
recharging of batteries, I know of several options, apart
from the old umbilical cord:shorepower: Solar, Wind,
and at least one windgenerator manuf. AMPAIR, also
makes a dynamo outfitted with a propeller that is
either towed behind the sailing boat, or transom
mounted. Can be found somewhere under renewable energy on
the web. I don't know how effective this is, but have
heard stories about how sharks go for them...<br>I
remember well, how much drag on the bicycle these small
dynamolights put on, and how little light came out of them.
Technology should have improved a bit since our
childhood!<br>3) I've seen pictures of a boat w. el-motor, but in
that particular case the motor was connected to the
shaft via a belt. To me this seems a little flimsy, and
I don't like the sidewards pull on the shaft. Even
if triple-pulley is used (if one belt breaks, maybe
the other two will hold...)it still leaves the
problem w. the sidewards pull. The biggest advantage I
see with this system is, that you can get the motor
above spray and bilgewater-sludge...
