how about some more techs involving magnetic applications.
1. like a Cart Booster, that when powered by a magnetizer works similar to a gold track, however, it will boost the minecart forward instance at max speed when placed to the right of the tracks, this way you could prevent boosters from launcher you the wrong way using detector rails to turn the magnetizer off when coming from the wrong direction so your cart will stop, or set it up to correct your direction and launch you the other way.
2. Coil-Gun, works like a mining lazer set at Long Range but travels 32 blocks destroying everything in it's path regardless of the material, except for reinforced stone and bedrock. will only go through 8 reinforced stone blocks or so. this however costs 1 Refined Iron as well as 100EUs per shot. Recipe would be something like this:
=Magnetizer
3. Unit Accelerator (player cannon). when filled with 10,000EUs and applied a redstone current, players equiped in metal armor would be accelerated and "thrown" roughly 128 blocks (on a flat terrain) at a 45 degree angle at the speed of quantum legs when leeping with boots under the effect of Speed Potion 2, into the air at the specified direction. you could then either make a pool of water to catch you, a rubber trampoline to bounce you back up and resume your flight for long distance travel, stop yourself with your epic Quantum Boots, or simply pray you survive the fall by slamming into the tip of a mountain. when used in unison with quantum boots you could set of precise landing points to land on a stone pressure plate and launch you again in a different direction. this would be a hazardous yet more efficient and advanced form of transportation after aquiring quantum armor to survive the journey. or if you did the calculations paerfectly, you could use it as a catapult to get into you mountain side or arial living quarters. i suppose you could also specify this to shoot you straight up to the top of the world (for those of you that want an arial castle or ship with no ground access point other then getting "beamed up").
