The parent company of Google received the green light on Friday to provide emergency cellular service to hurricane-ravaged Puerto Rico using balloons.
The Federal Communications Commission (FCC) announced it had granted Alphabet Inc. permission to use solar powered balloons to bring cellular service to the island, which has been left largely without power since Hurricane Maria hit last month.
Tidal and wind energy are being used to generate hydrogen in a pilot project installed in Orkney, Scotland, called Surf ‘n’ Turf.
The project was launched earlier this week by Paul Wheelhouse, the Scottish Government’s Business, Innovation and Energy Minister. He officially unveiled the newly installed hydrogen fuel cell at Kirkwall Pier. Other elements of the system, including an electrolyser, have already been installed. The facility produced the “world’s first tidal-powered hydrogen” in August, the European Marine Energy Centre says.
Even a “fatberg” — an enormous clotted, mass of fat and garbage found clogging a London sewer — deserves a second chance, and the biggest fatberg ever found in a British sewer recently got one.
The fatberg, a cement-like plug of accumulated cooking grease, diapers, wipes, sanitary products and other refuse that was flushed down toilets, extended through 820 feet (250 meters) of Victorian sewage pipe, and weighed an estimated 143 tons (130,000 kilograms).
Off the coast of Catalina Island near Los Angeles, a prototype of a new “kelp elevator”–a long tube with seaweed growing on it that can be moved up and down in the water to access sunlight and nutrients–will soon begin tests.
Small farms in Japan are struggling to survive. Rural populations are shrinking, and the average farmer is 67 years old. But two new farms will test a different business model to try to reinvigorate the sector: solar panels with mushrooms growing underneath them.
Talk about having your solar powered cake and eating it, too! A researcher at UC-Berkeley has figured out that when you coat a certain kind of bacteria with nanoscale solar panels, you can get it to make biofuel, plastics and other products from sunlight, carbon dioxide and water. The process is 80% efficient, which tops natural photosynthesis, and it involves zero waste.
In order to rely on renewable energy sources like wind and solar power, the world is going to have to find efficient ways to store electricity, saving it up for times when the wind is not blowing and the sun is not shining.
