Hi o/
I downloaded your mod to try it out, and it's very interesting to play with it :)
However i have a small feedback : it's quite hard to understand how they work. I tried giving them liquid fuel but they have no input, i tried manually inserting burnable items but there is seemingly no inventory dedicated to that... then only i tried with inserters and it worked :D
So i would advise to clarify that in the tooltip, adding something like "fuel can only be inserted via inserters"
Also, if I open the beacon UI and wait some time, the consumption tooltip disappears for some reason
Thanks !

Yeah, these are just powered by solid fuel. Currently there's no way to insert fuel manually, I need to implement that and rebuild the UI to show everything at once. The tooltip disappearing is unavoidable due to how it's implemented, it's only built for the tooltip in-world, not the UI.
