Wooden conductive pipes are a vital part of any energy grid in BuildCraft. They are used solely to extract energy from engines which would otherwise have to be placed directly next to the machines they are powering. Some machines cannot be powered effecively unless they are connected to more engines than they have sides, necessitating the use of conductive pipes.
Like other wooden pipes the conductive version does not connect to further wooden conductive pipes. Standard stone or gold conductive pipes must be used to connect from the wooden pipe onwards,
