Clay-land pasture (not sure if that affects it!) and I need to explain it using simple energy budget factors such as latent heat, sensible heat, solar radiation, reflected radiation, heat absorbed into the soil and outgoing long wave radiation... any ideas?!

if it works half as good as they say, why doesnt it outsell regular air conditioners?
since it is so simple and cheap to make it should cost way less than a complex window AC, but it costs more, why?
are they greedy or hiding something?

One problem creationist sceince has encountered is that stars are millions of light years away, and yet we can see countless numbers of them. Is it possilbe that, because the speed of light is affected by gravity, that it would go much faster in space, where there is little or no gravity? Be sure to support your answer conclusivly and logically.
