Cold Sky Lab

Cold Sky Lab is an amateur project on passive radiative cooling: 
a technology that dissipates heat toward the sky without 
consuming any energy.

We are not a professional lab — just an engineer, a garage, 
and a lot of curiosity. We build, measure, fail, and document 
everything.

The idea is simple: Earth's atmosphere has a transparency 
window through which heat can escape directly into space, 
day and night. What if we used this window to cool buildings 
and systems without electricity?

Europe has the highest heat-related death rate in the world. 
We won't change that from a garage — but we can learn, 
share, and maybe inspire someone who can.
