This 2lb pack-able mini/micro turbine looks promising, for those areas where you can get clean winds. Could replace or augment solar panels. When the sun is not out but the wind is blowing..
Estimated to generate "a constant output of 5 Watts at a wind speed of 18 km/h'
It won't run an air-conditioner,, but should keep your cattle prod topped off??

Anyone tried similar gear?
