A practical artificial leaf that can turn sunlight and water into energy as efficiently as the real thing has long been a Holy Grail of chemistry, and researchers at MIT may have finally done it. Today at the National Meeting of the American Chemical Society researchers from MIT’s Nocera Lab, led by Dr. Daniel Nocera, claimed that they’ve created an artificial leaf made from stable and--more importantly--inexpensive materials.
Viruses generally get a bad rap, but they can also be very helpful little machines. For instance, bacteriophages have been engineered to clear up infections that seemed otherwise untreatable, and genetic material from viruses has been used to ease biofuel production.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
