DevBlog #20 - Characters filled with character! And some other cool stuff.

Space and asteroid stations should be a great addition to the game, but I am wondering how will they (and our ships) be powered?

Will there be some sort of crystals that you can harvest during travels or maybe we will use more conventional fuel stored in tanks?

Will powering the ship engines be different from powering the ship rooms? (for example crystals for power core and fuel for engines)
Maybe there will be possibility of refining power source (be it fuel or crystals) to be more effective?
