Multi-task Work Canon
Just the same idea as the Mining Laser, but mounted in some static base, a cannon that could be pointed in any direction and "fired".
There are some modes around there that have items like this in some way, just like the Planes mode made by Flan. But the difference is the next:
The canons that already exists are only-weapon designed, and also they use no power, but bullets that you must have in your hand.
This different canon could use energy, work as the same way about maneuverability (turning capacieties and so), and like the Mining Laser (but stronger) too,... But with something more. Trough some plot about generating great static charges and using for levitate some objects, the canon could be capable of placing some blocks too (previously in hand, or into some slot of some GUI).
The use of this kind of canon could be the deffense of a place, the attack, the work in a quarry or so for long range and big scale mining, and also the building from some distance.
In this way, 4 canons, place in 4 sides of a construction, maybe they could make an entire house in just seconds (eating EU balls with the same size of the Sun).
This could be the best ever building tool, and give to the nuclear power and high tier energy production an use.

Also,... this kind of canon could be used later mounted in some vehicles (water, ground, or air). But at this starting point, it could be a really good deffensive/ofensive weapon, a good masive mining tool for long-while quarrys, and very good building tools. Also, the energy, if the canon is conected to some kind of big battery just like a MFS, will never lack (also de MFS conected to energy generators...).
1: would need an MFSU, not an MFE.
2: Alblaka already denied all weapon requests.
3: Buildcraft already has a fast builder.
4: This would take a freakin long time to code, and would you rather have this 1 thing or half of T4?
