hi ppl,
How do these guys http://www.solarmissiontechnologies.com/ work out what the interior temperature will be and how fast the resulting hot air will move?
thanks :)

Reasoning
Well,
A lot of thought and explanation has been given to the argument
'..,and since he has a PhD in <insert field name> he knows what he is talking about!"'
I prefer to attack the root, why choose that arguement? Obviously the argument is an old one or at least prviously...
Hi
Can anybody tell me if there is a way to work out how hot it gets in a glasshouse?
I realize it would depend on the properties of the glass but I don't know that either. Which properties do what?
thanks guys

answers' answers so far
Hadn't thought of ice Lethe. But I would like something that doesn't change it's physical properties so radically with the change. Does mercury fit the bill? if so is there something similar?
Alas no Lurch the reverse lava lamp was just the analogy. But tell me more...
Are there any materials that contract when a small electrical current is applied to it? What would be the necessary physical properties of such a material?
CJ
Ok, is there any solid, liquid, or gas that becomes heavier as it gets warmer and lighter as it gets colder? Like a reverse lava lamp.
The little physics I know says no but I Know VERY little, you know?
