Having worked with compressed gas the other day, I'm fairly certain that compressing air heats it up.

So you're saying these Indians are either retarded (it's actually getting hotter inside their houses) or it's just a placebo effect?

>Dhaka now in INdia

>zero-electricity cooler
certainly possible
>not requiring energy to function
not possible

yeah, the theory indicates that it shouldnt, yet these people are doing it and funding it

looks like theres something not taken into the equation

the only way I can imagine this happening is if the faster air increases evaporation of sweat

You can have zero electricity air conditioning
If you evaporate water, it's the oldest form of A/C

But the air will expand again. It doesn't heat up.
The heat was already present, compression in itself doesn't add heat to the system its just all of the previous heat in a smaller space

>So does this shit really work?
No. Blowing air through a funnel doesn't cool it down.
