AGRIBUSINESS: How plants can generate electricity to power LED light bulbs.Researchers have discovered that living plants are literally 'green' power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an 'hybrid tree' made of natural and artificial leaves can act as an innovative 'green' electrical generator converting wind into electricity. Sustainable energy sources, which are pollution free and environmentally friendly, are one of the key challenges of world's future society. The interdisciplinary team of roboticists and biologists at IIT-Istituto Italiano di Tecnologia in Pontedera (Pisa, Italy), found that living plants can help with electricity. Fabian Meder, Barbara Mazzolai and their coworkers at IIT discovered that living plants are literally "green" power source, which may become one of future's electricity supplies that perfectly integrates in natural environments and is accessible all over the world.

Scientist discovers particular seaweed reduces methane to nearly zero in cow burps, farts.

Scientist discovers particular seaweed reduces methane to nearly zero in cow burps, farts. A P.E.I. farmer has helped lead to a researcher's discovery of an unlikely weapon in the battle against global warming: a seaweed that nearly eliminates the destructive methane content of cow burps and farts. Joe Dorgan began feeding his cattle seaweed from nearby beaches more than a decade ago as a way to cut costs on his farm in Seacow Pond. He was so impressed with the improvements he saw in his herd, he decided to turn the seaweed into a product. "There's a mixture of Irish moss, rockweed and kelp, and just going to waste," he said. "And I knew it was good because years ago, our ancestors, that's what they done their business with." The agricultural scientist, then at Dalhousie University, helped test Dorgan's seaweed mix, and discovered it reduced the methane in the cows' burps and farts by about 20 per cent. Kinley knew he was on to something, so he did further testing with 30 to 40 other seaweeds. That led him to a red seaweed Asparagopsis taxiformis he says reduces methane in cows burps and farts to almost nothing.
