Stirling Generator

Stirling Generator is a Power building in Surviving Mars.

Description
Generates power. While closed the generator is protected from dust, but only produces 10 power. While open the generator produces 20 power.

Strategy
Stirling generators do not currently require maintenance while closed. This is good to reduce the needed materials over a long term.

If you have a couple Stirling Generators at start, when you build your first dome, build a polymer factory and a fuel refinery (for the polymer factory) then open all of your generators allowing them to produce more power and to have the required polymers for maintenance.
