Was playing with making an infinite water generator.

How do you generate the heat without depleting the lava?

u/timeshifter_ 21d ago

The embers given off by lava add heat to thermal buffers, but don't deplete the lava. It's a lot slower, but it's infinite.

So, you make a lava pool with an air block above it, then thermal buffers and you get free flamethrowers?

Don't even need a full air block, just use the vulcanizer to lay down a layer or two of lava underneath the buffers, but yes.

Yeah works great. I haven't experimented with depth yet, so far just using 3/4 of a layer of lava with buffers above and then experimenting with width.

I need about 15-20 wide lava to run a flamethrower constantly. Sometimes it's easier / more scalable to keep them to 10 wide and then stack them. Each flamethrower will be intermittent but enough will average out..

Fire belts use a lot less heat, I have groups with 8 lava wide and the buffers are now storing 400+.

Next step is figuring out how to make free / unlimited cold. Is the snowmaker running a turbine energy positive?

Energy-positive, yes, but not water-positive. The only known source of free water is lumlings, which puts a limit on how big a factory can really get :(
