cansolair.com sells a $995 4'x7' air heater that collects "10,000 Btu,"
more than the 4x7x250 = 7K Btu/h that might fall on it on a winter day,
not counting the glazing transmittance and heat loss to the outdoors.
They say "Peak Btu performance will actually increase in colder weather
due to the rise in temperature between input and output."

Gotta luv it when marketing people try to 'puff up' a rather mediocre
product!!! Next, they'll be claiming it collects over 150 degree F !!!
