An interdisciplinary team of researchers at Vanderbilt University have developed a way to combine the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by previous “biohybrid” solar cells.
“This combination produces current levels almost 1,000 times higher than we were able to achieve by depositing the protein on various types of metals. It also produces a modest increase in voltage,” said David Cliffel, associate professor of chemistry, who collaborated on the project with Kane Jennings, professor of chemical and biomolecular engineering.
Connecting 25 gigawatts of offshore wind to the grid among the goals. Fresh off the record-setting solar weekend in Germany, the country's transmission operators say plans are in the works for a huge transmission line buildout to accommodate growing wind power resources.
The goal is to build 3800 kilometers (more than 2300 miles) of high-voltage lines—2100 km direct current lines and 1700 alternating current lines—stretching from the Baltic coast in the south to the North Sea, which is already home to a few offshore turbines (and the government wants about 10 gigawatts of offshore wind installed by 2022 in order to help meet the country's renewable energy goals). By 2030, the hope is that more than 25 gigawatts will be installed—something on the order of 5000 turbines, depending on size.
Transmission is no easy thing to build, however. The new lines will cost around €20 billion (close to $25 billion), and there will need to be some serious buy-in from the public and politicians alike to get the project done.
This device doesn't look like it will save the world. It won't, no miracle. However, "Vampire energy—the power suck when our devices are plugged in but turned off—costs U.S. consumers $3 billion a year alone"!!!
Just before the new Pope Francis was announced in Rome yesterday evening electricity consumption in Ireland fell by 142 megawatts or over 3pc as people stopped using their kettles and other appliances and just concentrated on the TV.
The authors didn’t intend it as an an analysis of the wind power production tax credit, but it’s hard not to see the results as one more argument to keep the PTC alive: Wind power reaches right down to the local level as an economic engine, boosting incomes and jobs in the counties where turbines go up, according to a new study.
“Taking into account factors influencing wind turbine location, we find an aggregate increase in county-level personal income and employment of approximately $11,000 and 0.5 jobs per megawatt of wind power capacity installed over the sample period of 2000 to 2008,” write researchers from the U.S. Department of Agriculture’s Eoconomic Research Service, Lawrence Berkeley National Laboratory and the National Renewable Energy Laboratory.
San Francisco is clearly embracing the 21st century trend of new urbanism. An inspiring proposal was approved last week to turn the heart of San Fran’s downtown area into a mecca of urban living.
Along with the existing plans for a new transit hub, all together it will create a more walkable, sustainable, and dynamic center that promotes core environmental values to the area. The Planning Commission of S.F. approved the addition of six new 850-foot skyscrapers along with one that will be 1,070 feet, superseding the skyline summit of the Transamerica Pyramid building, making it the tallest building on the west coast. In addition, a comprehensive transit hub nicknamed the Grand Central Terminal of the West is already in the works...
"UK-based Green Biologics has a store cupboard of 900 different micro-organisms which could end up changing the way we power our cars. These microbes have been cultivated and developed to break down agricultural waste so fast and effectively that one of the potential end-products, butanol fuel, could become 30% cheaper than petrol."
There is hopes with algae too for 3-rd generation biofuels. This is key research. We need them!
"Hydrogen fuel cells for cars are still wildly expensive, mainly because they have to use costly noble metals such as platinum. Now researchers have demonstrated that aluminium can be treated to store and release hydrogen."
