i guess you mean 1400 w-h? are you wasting the rest of the 8,000-10,000 w-h
of sun that falls on the photovoltaic panels on the roof of your van as heat?

you don't mention how you keep the van warm inside or make hot water. perhaps
the fan could be a solar chimney. or you might trickle a little water over
those pv panels, under another layer of single polycarbonate glazing. or hook
up a small model-sized jet engine powered by freon, a mini-version of the
ormat turbine generators used to make 5 million watts of electrical power
from 63 acres of solar salt ponds in the dead sea, starting from 170 f brine.
