I am having a bit of a quiet chcukle at all those people who are
planning on including a laptop in your bugout & longer kit. Mainly
because I believe very few of you would have seriously worked out your
power generation requirements. I'd be interested in hearing differently.

Accordingly you are invited to post you calculations here for the
education of others.


87 watts of solar panels (4 that produce 15 watts and a bunch of smaller
ones)
Chicom hand crank generator still in the box from CheaperThanDirt
Bike powered generator(s) that produce upto 24 volts
A car alternator I been playing with for a couple years that I've gotten to
produce current with both a lawn mower engine and a bike powered belt drive
monstrosity that turned out to be a big pain in the ass.
Nearly 600 amp hours of deep cycle and gel cell 12volt batts and several
6volt nicad lantern batts.

Now when the hell are YOU going to post something useful instead of your
usual sneering bull*** oneliners?

Yes, but have you actually used these to power your needs?

What usable power do you actually get from the solar panels? aka how many amp hours a day can you put back into those deep cycle batteries? my rough calcs suggest that it would take those panels about three days to recharge a 100AmpHr deep cycle battery.

How long can you wind that hand crank generator?
What power does it produce?

Same questions with the bicycle powered generator?

you are ahead of me in the car alternator area. I have recently been given two old lawn mowers that are targetted for my first home built battery charger.

Why did you go for 600Amphr in 12V batteries?
a) it was what i could afford,
b) it was the only way I knew.
c) the batteries need to be moveable by hand to power pumps, etc
d) ????


Someone has posted a classic example of the problem with modern laptops aka they do not run easily at the convenient battery values. This means conversion and inefficencies.

Have your worked out how many hours you need to handcrack or ride that bicycle gnerator to run your laptop for an hour?
