Petroleum use is rife with environmental and security issues, and first-generation biofuels fall well short of carbon neutrality. Moreover, as global food crops literally lose ground to biofuel production, mounting scarcity is driving up food prices, increasing global hunger and political instability.
But what if we could have our rice and burn it, too? What if we could derive energy from crops without killing them, or generate power using plants and land not needed for food, all through the power of microbes?
How can we live on a planet overflowing with 326 million trillion gallons of water and still face shortages? Even if only about .05 percent of it is drinkable, shouldn’t there be some way to purify the rest? Actually, people all over the world convert seawater to potable water, but the process tends to be prohibitively expensive at large scales. Even so, with looming droughts, natural disasters and the large-scale redistribution of moisture threatened by climate change, the need for a solution grows more essential every day.
