just informing to fend off possible propaganda, cause most other buildup games here listed as popular are recent TV CO2 view etc ones leaving important details out such as Winter = 0 solar output, which leads to a false image that you could replace preexisting infrastructure. :)

And to learn more: the way "heat sinks" actually work is not by making heat in the air disappear, but  to redirect heat from something it's attached to into the air by maximizing the surface area towards the air, at least that's how it's done in computers, similar to pipes.
