Coral reefs will continue dying unless carbon output drops
Growing an endangered species of coral in a lab is one thing, but rebuilding a reef damaged by ocean acidification is a complete other. On paper, though, it's possible. A group of researchers attempted to counter the effects of rising carbon dioxide levels around Australia's Great Barrier Reef by pumping sodium hydroxide into lagoons that were isolated from the ocean during low tide, according to The Verge.
RC car runs on soda can rings, Doc Brown approves (video)
Many a future engineer was inspired by Back to the Future's Dr. Emmett "Doc" Brown, and not just because he proved that unkempt eccentrics could truly change the world. No, he also pioneered Mr. Fusion, the coffee maker/cold fusion reactor that turned garbage into energy. And while we're still waiting for cold fusion and time travel to become a reality, today we're all one step closer to waste-powered cars. A pair of Spanish engineers have recently unveiled the dAlH2Orean (see what they did there?), a R/C car that runs on aluminum. Dropping a few soda can tabs into a tank of sodium hydroxide produces enough hydrogen to power the little speedster for 40 minutes – at almost 20mph. Hit the video above to see it in action, along with your daily helping of the Chemical Brothers. Fitting.
