This power was just clicked upon and will begin transmitting electricity, eventually powering the heater block.

Power is a fixed solid which functions as a controllable source of electricity. Power functions exactly like metal, but it can spontaneously create electricity by being clicked upon with the touch tool. After being clicked upon by the touch tool, power generates electricity from the point where it was clicked. Power, like metal, can both use this electricity and pass it along. Universes may use power as a start point, in which the player of the universe must click the power to start transmitting electricity and begin the level.
