2) Dispenser fires a fire-charge at the block.

Closing Mechanism

1) Dispenser pours a bucket over portal, extinguishing it.
2) Pistons fling forwards, crushing the water block.
3) Pistons pull back, the water being destroyed.

Areas of Further Development

1) Needs to be expanded to include nether
2) Will be expanded to include architecture other than the portal hall
3) Will try to improve the system to remove the dependancy on water buckets, which is a but- hole to deal with.
