Steam Upgrade (GregTech 4)

The Steam Upgrade is an upgrade added by GregTech 4, for EU-powered machines. It allows them to use Steam Power instead of EU, at a rate of 2 mB (Steam) : 1 EU.

Upgraded machines can use BOTH Steam and EU.

Upgrades are applied by right-clicking a machine, and cannot be removed, even with a Wrench.
