Study: Algae Could Replace 17% of U.S. Oil Imports
http://www.renewableenergyworld.com/rea/news/article/2011/04/study-algae-could-replace-17-of-u-s-oil-imports

High oil prices and environmental and economic security concerns have triggered interest in using algae-derived oils as an alternative to fossil fuels. But growing algae — or any other biofuel source — can require a lot of water.

However, a new study shows that being smart about where we grow algae can drastically reduce how much water is needed for algal biofuel. Growing algae for biofuel, while being water-wise, could also help meet congressionally mandated renewable fuel targets by replacing 17 percent of the nation's imported oil for transportation, according to a paper published in the journal Water Resources Research.

Researchers at the Department of Energy's Pacific Northwest National Laboratory found that water use is much less if algae are grown in the U.S. regions that have the sunniest and most humid climates: the Gulf Coast, the Southeastern Seaboard and the Great Lakes.

"Algae has been a hot topic of biofuel discussions recently, but no one has taken such a detailed look at how much America could make - and how much water and land it would require — until now," said Mark Wigmosta, lead author and a PNNL hydrologist. "This research provides the groundwork and initial estimates needed to better inform renewable energy decisions."

3. The Algae will pay for the war. The merpeople will greet us as liberators.
Shouldn't take 6 weeks, never 6 months.

5. ...but they won't
Feeling pretty cynical about our ability to do anything but keep on going down the fossil fuel/peak oil/fracking death spiral.

6. Like fusion - promises and disappointments
...so far no practical mechanism exists for getting oil from algae on any useful scale. Like fusion, it sounds great on paper, then it fails to work out, over and over and over again.
