I have found that a transformer does not require energy to create fuel. He just needs to be on the grid. https://drive.google.com/file/d/1JTyWZZqZjUIYX4tuJ-tVXjL9KQFOjiID/view?usp=sharing

Right, thanks for reporting, I'll try to fix ASAP.

It should be fixed, at least for now.

Yes, now without a reactor, the energy of the machine is not replenished. However, as I noticed, the transformer replenishes part of the transport energy scale when it reaches zero. It makes sense to make a replenishment at a certain minimum, because after reaching zero, the car starts spamming with a signal of the end of fuel.

Oh, I'll try to do it

I've changed the logic a bit, hope it'll work better, uploading a new version soon.
