In light of the strong evidence that growing corn, soybeans, and other food crops to produce ethanol takes a heavy toll on the environment and is hurting the world’s poor through higher food prices, consider this astonishing fact: This year, more than a third of the U.S.’s record corn harvest of 335 million metric tons will be used to produce corn ethanol. What’s more, within five years fully 50 percent of the U.S. corn crop is expected to wind up as biofuels.

The new recycling program by the U.S. Navy in collaboration with GE Aviation is sure to do wonders for the environment. The duo have initiated a program under which rhenium-bearing aircraft engine components will be recovered from out-of-service F404 and F414 engines, after which the precious metal would be used for the manufacturing of new engine parts. The project known as the GE/Navy Reclamation Program aims at reducing raw-material requirements, lowering dependency on foreign sources of rhenium and providing financial “credits” the Navy can apply to future engines and hardware.

Ocean levels are rising around the globe, so rather than tethering our buildings to the sinking shoreline why not suit them for a life at sea? That’s the approach behind the Water-Scraper, a futuristic self-sufficient floating city. A special mention in this year’s eVolo Skyscraper Competition, the design expands the concept of a floating island into a full-fledged underwater skyscraper that harvests renewable energy and grows its own food.
