While we’ve written recently about “artificial leaves” that emulate the photosynthesis of their real counterparts, researchers have announced the discovery of a way to extract hydrogen from any plant, which “could help end our dependence on fossil fuels,” according to Y. H. Percival Zhang, associate professor of biological systems engineering in the College of Agriculture and Life Sciences and the College of Engineering at Virginia Polytechnic Institute and State University (Virginia Tech). The school describes the process as a “breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.”  Zhang has been working on the problem for over seven years, and like many pioneers, has endured the critical appraisal of those not in tune with his aspirations. Esquire magazine in its November 2006 issue labeled Zhang’s early iteration of his idea to break down plant sugars to create cheap cellulosic ethanol and possibly even hydrogen as the “Crazy idea of the year: “sugar cars.”  …
