Episode notes
CO2 Is Earth's Dual Key
- CO2 both stabilizes Earth's temperature and supplies the carbon backbone of life through photosynthesis.
- Its dual role makes it central to habitability and biospheric energy flows across deep time.
Life And Fire Share One Reaction
- Aerobic respiration in organisms and combustion in fires obey the exact same chemical reaction: organic matter plus oxygen yields CO2, water, and heat.
- That shared chemistry links biological metabolism, fire, and fossil-fuel power generation.
Cells Use Turbine-Like Nanomachines
- ATP synthase is a literal spinning turbine that converts proton flow into usable chemical energy (ATP).
- Brannen likens cellular turbines to pumped-hydro storage and large-scale energy turbines.
