1.15.2 - Forge

Cobblestone Generator - The "SimpleCobblestoneGenerator" from the old mod. It works the same with cobble being produced as fast as you can take it out. This can optionally require power (see server config which is found in the world folder)
Tree Farm - The "SimpleTreeFarm" from the old mod. It works the same as the original design with a small difference. The farm prevents trees from growing nearby, instead simulating the tree's growth in a pocket dimension. This process prevents block updates occuring in a world, making it less laggy on servers in theory. It has some configs to control whether it uses power.
Coal Generator - This is a block which generates power by burning any item that could be used in a furnace. The amount of power it creates is modifiable in the config.
Solar Generator - This is a block which generates power using the sun. It only works if it can see the sun, so not when it's indoors, at night or when it is raining.

1.14.2 - Forge

In 1.14.2 I have rewritten this mod from the group up. So the features are being re-added one-by-one.

Features added so far:

Cobblestone Maker - This creates cobblestone as fast as you need it to, optionally requiring power (not by default)
Tree Farm - This farms wood, optionally requiring power (not by default)
... thats all for now

The only thing in the 1.12 version of the mod is some metals, namely copper, tin and lead.

Note: The 1.12 version is broken and should not be used as it has an outdated version of the RFAPI

This mod adds a bunch of stuff..... but you can turn most of it off.

Here is a list of things that are included in the mod:
