Sorry I know this is a bit old, but I just got to say; they got to you.
Optic focusing 'will' contradict the second law, but you nor nobody else wants to face that burden...

Thank you Mapes.
Yes I think that will help me as soon as I understand the formula correctly.

Okey. But is this only because air closer to total zero is harder to expand, or is it more or less proportional with the change of temperature?
Sorry if this is a dumb question...
Okey, simple question. As written in the title, I'm really not sure how this should work.
Should hot air need more energy to compress than cold air, is it the other way around or is there no difference?
This is asked because I need to find out if a physical system could work or not...
Any...
