Thermoelectric Generator

The Thermoelectric Generator is a power generation block that generates electricity by using the difference in temperature between two blocks. The maximum power it is capable of providing is limited to 250 F/t. The greater the difference in temperature between the two block in pairs of temperature source, the more it produces.

The power Output is calculated as such

n is either 1 or 2 depending on how the block is surounded (see below)
i is a coefficient multiplier value defined in configuration
Δθ is the absolute diference in temperature between the two blocks

as the square root of the absolute difference in temperature between the two blocks divided times 2 then multiplied by the config coefficient and the number of pair surrounding the block.

You can either make a single pair generator or a dual pair generator:

the X pattern is two times more productive than the simpler I Pattern.

Blocks & Fluids Temperatures

Here is the list of every Block & Fluid that can be used with the device as well as their temperature in Kelvin:
