Block of Redstone

Blocks of Redstone act as piston-movable redstone power sources which cannot be turned off. When power is applied to the block, it is unaffected and will still output a redstone pulse regardless. However, because of the way blocks act; they cannot power blocks adjacent to it.

Usage
The block of redstone was introduced mainly to serve the purpose of providing a solid block that can act as a redstone source.

A block of redstone will power adjacent redstone wire (including above and below), correctly-facing redstone repeaters and redstone comparators, and adjacent mechanisms (pistons, redstone lamps, etc.). It will not power adjacent opaque blocks. Redstone wire will configure itself to point towards an adjacent block of redstone.

The block of redstone also serves as compact storage for redstone dust, like other blocks of minerals (Block of Iron, Block of Gold, etc.).
