Our group works in mountain areas in high
latitudes, betwen 35º and 55º S, daylight in winter varies from 8 hs in the
north to 4.5 hs in the south end, so lighting is a concern. (Open fires
lights!!) HBLED, high brightness LEDs, seems to
be an appropiate solution (See http://www.lightuptheworld.org/ )
Thermoelectric generators could be in many cases a better power source than
PV panels, given the power reqs of HBLEDs (1 W HBLED gives 40
lumens!!).
( In fact our most cost effective
power source is a pico-wind generator, the area has quite strong and
regular winds but.... people are clever and most houses are built in wind
protected locations!!)
