A Thermopile is a RedPower 2 machine used for generating blutricity. A single thermopile has a maximum output of 1 amperes and 60 volts.  Because it doesn't need light, unlike solar panels, it can produce throughout the night. Thus averaging the same amount of power produced over the course of one minecraft day/night cycle as a single solar panel .  This efficieny is theoretical (see additional effects).

Power Output DetailsEdit

To calculate the power output of a thermopile, one must first count the number of "hot" and "cold" blocks on each of its faces.

Heat and Cold TablesEdit

Block Heat
Lava 100
Fire 25
Torch 5
Jack 'o' Lantern 3
Air (Nether) 1
Block Cold
Ice 100
Snow (Block) 100
Snow (Covering) 50
Water 25
Air (Normal) 1

Additional EffectsEdit

If there's at least 100 heat and 200 cold, every second there is a 1 in 300 chance for adjacent lava source and flowing lava blocks to turn into obsidian or basalt, respectively.

Additionally, if there is at least 100 heat, every second there is a 1 in 300 chance for adjacent snow (block or covering) or ice blocks to melt.

Power OutputEdit

A thermopile will produce 0.005*min(heat, cold) amps, or 0.3*min(heat,cold) watts.

Suggested DesignsEdit

As thermopiles require maintenance with 100 heat or more if the design includes snow or ice, and the next best cooling block is water, it is suggested that one surrounds a vertical stack of thermopiles with 3 water and 1 lava. This produces 0.005*min(100, 3*25) = 0.375, amps per thermopile. Note that a solar panel produces 2 amperes, by comparison.

Thermopiles with a little automation can produce 0.005*min(2*100, 2*100) = 1 amp per thermopile. They use 2 ice blocks supported with Xychorium Ice and 2 flowing lava blocks supported with block breakers. This video explains how to make a tile-able max-output thermopile.
