Try to dedicate more ram for technic launcher.

It may be just because you didn't dedicated enough ram to java.Though i am not sure cause i am on mac it's little bit different when you launch server and do this kind of stuff.

NP :D

No, you can use steam,redstone or combustion engines(you just put them next to quarry and power it up) i suppose you use energy link to be able to run quarry by electrical power . Of course electrical energy is way faster i think it's most powerful way to run quarry especially if you use solar power.You don't need to hydrate and it never explodes like combustion or steam engines.I don't recommend use redstone engine cause it's really slow... I hope i helped..
