Clark, SD | Their numbers are off. This is the actual math using the Birkeland eyde process, which is the process the machine uses.
Energy Requirements for Claimed Production
Claimed Production: 110,000 lbs of nitrogen annually
100% efficiency :
N2 bond energy:0.942 MJ/mol
Power input: 1.1 kW continuous
Annual energy: 9,636 kWh = 34,689.6 MJ
Moles of N2 that can be split: 36,825 moles
Mass of nitrogen produced: 1,031 kg (2,273 lbs - in a full year of operation)
Energy required at 2.0 MJ/mol (roughly 50% efficiency, still super optimistic) : 3,571,428.57 MJ
Required continuous power: 113.3 kW
Actual Machine Specifications
Power draw: 1.1 kW
Annual energy consumption: 9,636 kWh
Maximum theoretical production: 485 kg (1,069 lbs) annually
Assuming you are paying $0.10 per kWh thats $963.60 for 1069lbs of nitrogen
Meaning that even using better than actual efficiencies it is theoretically impossible that the machine produces the amount of N that they say it does. To hit that number...even figuring better than actual efficiencies...it would require 113kW of continuous power...yet they saw it only requires 1100W. | |
