Bioreactor Fuels Statistics

So I just built a bioreactor for the first time today. To say that the experience was underwhelming would be an understatement. I was constantly running out of power, and had to refill the stupid thing every couple of minutes. In addition, the recharge rate is abysmal. I assumed that I was just using a poor fuel, so I created a new world with a testing facility. Here are the results for several different types of fuel:

Fuel Stats


  • Regardless of fuel type, a bioreactor will only output one power every 12 seconds (or 0.0833 p/s). Putting more stuff into the reactor does not change this, it only makes the reactor run longer. To get more power/sec, you need to construct additional pylons bioreactors. As far as I can tell, it would take somewhere from 10-15 bioreactors to run a single water filtration machine non-stop.
  • If you want to use a bioreactor setup, do not feed it with plant matter unless you enjoy constantly micromanaging your power systems. Reginald is the best input that I have seen so far.
  • If you really want renewable energy, your best bet is to build a thermal plant or solar farm and then use power transmitters.

Let me know if I’m missing something that makes the bioreactors great, but in their current state, they are far too underpowered for my taste.
