This Technology Review article on EEstor’s new battery-ultracapacitor for energy storage. EEstor claims that their battery hybrid has 10 times the capacity of a traditional battery at half the cost. That seems like a bold claim to me.
This USA Today article discusses how the increased (subsidized) production of ethanol has increased the demand for corn, leading to higher corn prices. These higher corn prices are rippling through the economy, not surprisingly. The article also does a good job of its economics, because it points out that the ripple will include rising soybean prices as farmers shift acreage from soybeans to corn.
Relatedly, see this Times (UK) article on the cool reception among Congressional Democrats to increased ethanol in President Bush’s State of the Union address (with my Midwestern senator, Barack Obama, as a notable exception).
