Effect +0.5 Extraction Rate

"Develop techniques to improve the rate of extraction from all refineries."

Raise the extraction rate from every refinery. It's the same effect as half a collector.

It also raise from 10% to 15% the amount you gain from unextracted crystal at the end of a level.

Good research, but expensive (because of the prerequesites).
