Conductive Pipes

Wood, Stone and Gold pipes can be combined with Redstone Dust to create Conductive Pipes. These pipes are the only kind of pipes that can carry energy produced by Engines to machines that can normally be powered by engines (e.g. Quarries, Mining Wells and Oil Refineries). Energy is displayed as a solid line of blue matter travelling through the pipe, with varying thickness depending on how much energy is passing through the pipe.

Pipes can explode if you make a loop.

There are 4 types of conductive pipe: Wooden, Stone, Gold, and Teleport.

Stone Conductive Pipes
Stone conductive pipes are used to transport the energy after it has been extracted by the wooden pipes. These pipes lose 1% of their energy for each block travelled.

Gold Conductive Pipes
Gold conductive pipes are also used to transport the energy. These pipes only lose 0.01% of their energy for every block travelled and so it is better to use these for transporting power long distances. In theory, you could use these to make a power grid that can cover your entire world, so if you want to make a Quarry, just tap into your power grid!

Teleport Conductive Pipes
Teleport conductive pipes can send power to any other teleport pipe if placed by same player, on the same frequency, and have "can recieve" option activated. There is a distance limit, so placing pipes to "boost" the teleport signal may be needed.
