Solar harvesting: can make a fortune from this. Ofset costs and you could be raking in around 100k week if you run 2-3 harvestors.

Wind harvesting: Similar to solar, but is cheaper to maintain. Doesnt get the same amount of resources

Selling fac items: Weapon upgrade kits seem to be lacking on the market. Can split crates into 10 and sell them for 3k on the bazaar i guess.

Thats it for the time being, personally i want to grab a few solars over the next few days, should be about 25-35k and start raking in the cash and powering the factory.
