I have a Personal Mineral extractor that I've used before without any problems. I recently set it up again, but when I click on Deposit Power, the amount of power I can use is 0. I have in my inventory Class 5 Solid Petrochemical fuel and "unknown" liquid petrochemical fuel. Why won't these work in the harvester?

Those two types of fuels just dont work in harvestors. The only ones that do are wind energy, solar energy, and radioactive.

D'oh!! Thanks for the info.
