Could great walls prevent tornadoes forming in the American Midwest?

Could great walls prevent tornadoes forming in the American Midwest?: "The Great Wall of China was primarily built to keep out nomadic tribes, but a new study suggests constructing great walls in the American Midwest could keep out a different kind of threat – tornadoes. It might sound far-fetched, but a study conducted by Dr. Rongjia Tao from the Department of Physics at Philadelphia's Temple University suggests there is in fact some scientific merit to it. Strategically placed, 1,000 ft (300 m) high great walls could negate the forming of the destructive wind storms in Tornado Alley, and by extension, the destruction they leave in their wake"

Solar-powered electrochemical cell used to produce formic acid from CO2

Solar-powered electrochemical cell used to produce formic acid from CO2: "Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid."
