COURSE OVERVIEW • 1) Understanding how plants work.
Understanding how plants work. • Solar input = 1.3 kW/m2
Understanding how plants work. • Solar input = 1.3 kW/m2 • 5% (max) can be stored in organics
Understanding how plants work. • Solar input = 1.3 kW/m2 • 5% (65W/m2) can be stored • Humans consume ~ 100 W (360,000 J/hour)
Understanding how plants work. • Solar input = 1.3 kW/m2 • 5% (65W/m2) can be stored • Humans consume ~ 100 W (360,000 J/hour) • Plants must have high surface area & low metabolism
