which sounds like Yahoo directories <| sep |> You should not need any vents at all , nor hardly any management if you built it right . Build 1 pistonwheelgenerator . Now make a small boiler and add pieces on to it until you max out the piston . You ' ll notice that adding extra pistons or wheels or generators makes no difference in the total output . Only steam volume really matters , and that ' s set by the boiler . So if you have pistons getting damage from going too fast , you have too much boiler . Note when you first hook them up , the boiler may be overpressure and cause some damage until it ' s equalized . That ' s normal . Also , you should be charging batteries with a turbine instead of pistons . In steam engines these are separate things , where as in fuel engines it does both . A turbine has no pressure cap , so an equal number of turbine pieces and boiler pieces can just be piped together very easily . A 6 piece SMALL turbine will create 1200 energy per second for about . 5 material . It also only takes up 2 x 6 or 1 x 12 space and needs no outside venting . This will NOT run propellers , but it will charge batteries . I have found no reason to release steam in the current system at all . You just need to fix your boilers . I would really like a pressure based switching pipe , but we ' ll just have to hope .
