ECOtorio

This early electric furnace is even slower than basic stone furnace, but producing less pollution (for a given amount of resources smelted)
64 of them are needed to smelt a full yellow belt of iron/copper (32 for stone)

Some numbers:
- To smelt a full yellow belt of iron (15 i/s), 64 Electrified Stone Furnaces are needed - This results in using 2.88 MW of power, and producing 32 pollution per minute
- To produce the power via boilers, the output of 1.6 boilers is needed (ignoring inserters), producing 48 pollution (total 80) and consuming 43.2 coal per minute.
- Same result with just stone furnaces (48pcs) produces 96 pollution p.m., and uses 64.8 coal per minute
- Result: The Electric stone furnaces are 50% more energy efficient and 20% less polluting - The drawback is you need more of them and more inserters and belt (more costly) and more space used as well.
- Steel furnaces are 100% more energy efficient than stone furnaces but the same pollution (96), making them slightly less Eco but consuming less coal (and using a lot less space)
- Electric furnaces with 2x Efficiency module 1 (24pcs) however win by far in all categories - Only 9.6 pollution themselves, and 31.2 from the boilers, making them twice more Eco than this mod! They are, however, expensive to build.
