Boat to produce hydrogen from the ocean for clean energy storage

February 21, 2017

In a bid to prove the effectiveness of hydrogen as a renewable fuel, Victorien Erussard and Jérôme Delafosse will sail around a world in a boat powered by the gas – made from the elements they encounter on the way. “The problem is that 95 per cent of the hydrogen that you use already is made out of fossil energies,” says Delafosse. “We will produce hydrogen onboard from the ocean, we…


Multi-energy-harvesting device to push IoT development

February 8, 2017

Researchers from the University of Oulu in Finland have found that a mineral with the perovskite crystal structure has the right properties to extract energy from multiple sources at the same time. Perovskites are a family of minerals, many of which have shown promise for harvesting one or two types of energy at a time—but not simultaneously. One family member may be good for solar cells, with the right properties…


Computer energy to be regulated in California

California’s state energy agency voted unanimously Wednesday to approve new regulations for energy efficiency in desktop computers and monitors. The rules, passed by the agency, the California Energy Commission, are the country’s first attempt to regulate the energy use of desktop computers and represent another step in the state’s efforts to drastically lower its greenhouse gas emissions to address climate change. Computers use more energy than many other consumer electronics…

Methane emissions blow away efforts to slow down climate change

December 12, 2016

The powerful greenhouse gas, and main cause of climate change, Methane, is growing faster in the atmosphere than ever before. In fact global concentrations of methane is growing faster now than at any other time in the past 20 years. That is the message of a team of international scientists in the journal Environmental Research Letters. The group reports that methane concentrations in the air began to surge around 2007…


Google giant going green by 2017

December 7, 2016

The online giant, Google, said that all of its data centers around the world will be entirely powered with renewable energy sources sometime next year. Last year, Google consumed as much energy as the city of San Francisco. Next year, it said, all of that energy will come from wind farms and solar panels. This is not to say that Google computers will consume nothing but wind and solar power….


Tesla’s SolarCity sets example for the world

November 28, 2016

To celebrate its $2.6bn acquisition of SolarCity, Tesla has announced a major solar energy project: wiring up the whole island of Ta’u in American Samoa. Previously, the island ran on diesel generators, but over the past year Tesla has installed a microgrid of solar energy panels and batteries that will supply “nearly 100 percent” of power needs for Ta’u’s 600 residents. The project seems intended to show off the potential…


Nuclear waste to batteries starts diamond-age of power generation

November 28, 2016

New technology has been developed that uses nuclear waste to generate electricity in a nuclear-powered battery. A team of physicists and chemists from the University of Bristol have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current. New technology has been developed that uses nuclear waste to generate electricity in a nuclear-powered battery. A team of physicists and chemists from…


From-farm-to-fork: A Thanksgiving turkey tale

November 25, 2016

The carbon footprint of a typical Thanksgiving feast – roasted turkey stuffed with sausage and apples, green bean casserole and pumpkin pie – for each state has been calculated by Carnegie Mellon University researchers. The team based their calculations on the way the meal is cooked (gas versus electric range), the specific state’s predominant power source and how the food is produced in each area. They found that dinners cooked…


Microalgae: Fuel for your car, and for you?

November 22, 2016

Microalgae may soon combat global warming, climate change and food insecurity, according to a study published in the journal Oceanography. “We may have stumbled onto the next green revolution,” said Charles H. Greene, professor of earth and atmospheric sciences at Cornell University, and lead author of the new paper, “Marine Microalgae: Climate, Energy and Food Security From the Sea.” The study presents an overview of the concept of large-scale industrial…


Harnessing carbon dioxide needs engineered efficiency

November 18, 2016

The vast diversity of organisms on the planet expresses enzymes for the conversion of carbon dioxide into organic compounds, like sugar. Plants do the same through photosynthesis, and the efforts to harness these capabilities to transform CO2 into high-value products such as bio fuel and renewable chemicals have met with limited success. While increasing concentration of CO2 in the atmosphere poses a challenge, researchers also see it as an opportunity….
