LOL its part of a mod but yes XD and they do not need power! Just don't stand too close... Look at these game launchers, they install the mods FOR you so you don't have too.
(i have had SOME issues but they are fixed after the last update) Home | Feed the Beast :: Minecraft Modpacks - Texture pack - Maps Technic Launcher - Technic Platform ATLauncher - Home
I play the Yogscast ones on FTB, technic and ATL. They have mod pack support so if you have an issue they can help you, and they check the packs regularly to make sure they are working.
The issue with ATL is that you need a 64 bit computer with 64 bit java. My computer is a custom built gaming computer (still needs a few upgrades but we are getting there) so I do have the 64bit windows and java.
FTB its the most computer friendly one.
If anyone needs help with these let me know, my brother and I are good and fiddling with them. And if everyone gets on the same modpack we can hop on a server and play :)
