[MRCA] Field Day

[Scott Johnson]

I would do a bicycle mounted alternator.  FWIW, a brushless DC motor makes a nice PM three phase generator, the output of which can be rectified, filtered, and regulated.  How about a thermoelectric pile, heated by a Coleman lantern?  There are surplus Russian thermopiles on ebay all the time. AND you can still make partial output from a PV on an overcast day.  My home PV system (10kW nominal) make over 1 kW on a completely overcast day.

Thanks to all my fellow members for the creative  and well thought out suggestions.
Thanks to one of our members - - I think the best and simplest  solution (KISS) is to use "road flares" - - a single flare in front of each solar panel. The panels are small enough so 1ea flare should do the trick. I am off to the local Farmers Supply.

Anybody have any suggestions as to how to run a low power(5 watts or less)  solar powered station(no batteries) when it is raining and overcast?
