  • Lime Kiln Calculations - $2400 for a minimum 100kW heater element for 1 ton batch kiln, lasts 50-300 heats.
  • Bulk lime is $150-200 per ton - 10 cents per lb.
  • Around 1.4 kwhr/kg of lime production - or 1400Mwhr for a ton
  • Basic cost of open source - with 1 Cent Solar - we have 1400 kWhr * 1 cent/kWhr = $14 in electricity
  • Absolute base cost is $14 energy and $24 in Kanthal A1 wear - making a 100 lb sack of concrete mix come out to $4, which is near zero marginal cost.
