The U.S. Department of Energy plans to make a $105 million loan guarantee to support the expansion of an Iowa ethanol factory into the nation’s first commercial-scale plant to convert corn waste into motor fuel.

Since diving into the deep end when it comes to energy issues, almost every day sees new concepts, approaches, and technologies — fascinating, exciting, even hope-inspiring at times. And, to top it all off, so many of these are truly Energy COOL as well.
Innovative combinations of rather straightforward, well-in-hand technologies can offer real solutions to problems while creating new opportunities.
Several weeks ago, a group of researchers published an article in the Proceedings of the National Academy of Sciences documenting how relatively low-powered solar systems offer the potential to increase food supplies in impoverished arid regions while reducing demands for fertilizers and other costly (in fiscal and other terms)additives.
The 107 million tons of grain that went to U.S. ethanol distilleries in 2009 was enough to feed 330 million people for one year at average world consumption levels. More than a quarter of the total U.S. grain crop was turned into ethanol to fuel cars last year. With 200 ethanol distilleries in the country set up to transform food into fuel, the amount of grain processed has tripled since 2004.
The United States looms large in the world food economy: it is far and away the world’s leading grain exporter, exporting more than Argentina, Australia, Canada, and Russia combined. In a globalized food economy, increased demand for food to fuel American vehicles puts additional pressure on world food supplies.
