Redpower Machines is a module that has a lot of things in common with our other mods, as in, it has an item pipe/transport system too, plus some other stuff.
Here is a page that describes the stuff in it: (aside from the recipes page linked in the MC thread):
http://integratedredstone.wikispaces.com/Redpower+MachineMy main reason for proposing this module would be the Block Breaker. It would allow us to build cobble generators without needing bedrock, or quarries.
From that page:
The Block Breaker is used for tasks such as building automated cobblestone factories or wheat, flax, or sugar cane farms.
The recipe involves 6 cobblestone, a piston, redstone and an unused iron pick. Notice that it is so much cheaper than a quarry, which involves 11 diamond.
Also, ignore the Blutricity part of that page, it requires nikolite, which only comes with the Redpower World module, which won't be installed.
