Carbon Sequestration CE 394K.2 Juan Moran-Lopez
Quote of the Day “I’m not a prophet or a stone-age man, just a mortal with potential of a superman. I’m living on. I’m tethered to the logic of homo sapien, can’t take my eyes off the great salvation of (false) faith. If I don’t explain what you ought to know, you can tell me all about it in the next bardo.” —David Bowie

Possible Carbon Sequestration
Conclusions Austin can produce almost 1500 MW-h/day with only 10% of building area covered with solar panels Trees in 20% of open areas can sequester almost 40,000 tons of Carbon per year
