We cool every space and physical system, except humans. Until now.
Cooling vests built for the crews that work in real heat.
Above 80°F, your crew slows down.
The hottest days cost crews 30% or more of their output. The map shows how many days your region runs above 80°F, and where heat rules are already law.
