NOW UPDATED FOR FACTORIO 2!! (Does not require Space Age!)
Have you ever thought "crap, I have way too much wood and need an elegant and extremely dangerous way to get rid of it"? Now you can! The WOODBURNER PRO 2 feeds on wood and your soul -- just try not to get too close while it's running... it will kill you. Happily.
The Woodburner is entirely pre-configured -- just place it down, wait for bots to fill the train with as much wood as it can, and watch it run!
The train will only run when there is enough wood to fill the trains; it will happily chew through all the wood you've managed to collect, so if you need to pause it, toggle the combinator next to the train stop.
