Simulation Parameters
Adjust the controls to explore different stratospheric aerosol injection scenarios
Payload: 1.5kg •Cost: $198.78/kg SO₂
Cost Per Kg: Bigger = Cheaper
Standard Helium$292.97/kg
Standard Hydrogen$198.78/kg
Gigantic Balloon$5.21/kg

💡 Cost per kg = Total balloon cost ÷ SO₂ payload. Bigger balloons spread fixed costs over more SO₂, making each kg cheaper to deliver.

Cost Breakdown: Standard Hydrogen
