Interesting report about recent breakthroughs at Thomas Jefferson University, which could increase the potential to convert tobacco oil into biofuel. This short "synthesis article" from Wikinews cites a range of credible sources to support its overview of this promising green tech initiative.

Interesting story on how tobacco plants might be genetically modified to produce more oil, which could be used to make biodiesel fuel. Although mention is made of the desire to find "biofuel sources that are not also potential food," the fundamental issues of what else could be planted in place of tobacco, and of the energy/nutrient requirements to grow tobacco, are completely bypassed, lowering the article's interest to mere curiosity.

clear, nicely written, important BUT did the writer not at least question whether the resulting fuel might not give off something like second-hand smoke?

This article is not well sourced and misses the point that growing crops for biofuels uses land that could be used for food whether the biofuel crop can be used for both food and biofuels or just biofuels.
