"If you're using first-class land for biofuels, then you're competing with the growing of food. And so you're actually spiking food prices by moving energy production into agriculture" Bill Gates
"Better biofuels are a really big deal. That means we can precisely engineer the molecules in the fuel chain and optimize them along the way. So, if all goes well, they're going to have designer bugs in warm vats that are eating and digesting sugars to excrete better biofuels. I guess that's better living through bugs." John Doerr
