Some people have loads of energy, but what do with it? MAKE PURE ENERGY BRIDGES! With this fancy Machine, you can create semi-transparent glowing drawbridges made entirely of your easily harvested electricity! Doesn't that sound awesome?
Also... The more energy is flowing into the Machine, the longer the bridge is! So for example, if you connect a LV Cable to it, it's 8 blocks long. But If you hook it up to a HV Cable, it can be even 32 blocks long! But beware, it usually explodes if the amount of energy is too high.
How does it look: (Textures. :D, the dark "laser" field has 60% Alpha)
