Power-to-Liquid: 200 Liters of Fuel from Solar Power and the Air's Carbon Dioxide

Production of liquid fuels from regenerative electric power is a major component of the energy turnaround. The first 200 l of synthetic fuel have now been produced from solar energy and the air’s carbon dioxide by Fischer-Tropsch synthesis under the SOLETAIR project. Here, INERATEC, a spinoff of Karlsruhe Institute of Technology (KIT), cooperates with Finnish partners. The mobile chemical pilot plant that can be used decentrally produces gasoline, diesel, and kerosene from regenerative hydrogen and carbon dioxide. It is so compact that it fits into a shipping container.

Great Lakes scientists identify research challenges

The Great Lakes could be in hot water if the quality of the research and partnerships are not improved, warns a University of Windsor professor.

“Fresh water is arguably the most important issue for the world going forward to support the planet,” said University of Windsor professor Aaron Fisk, the Tier 1 Canada Research Chair in Changing Great Lakes Ecosystems. “But the amount of resources that are dedicated to the Great Lakes from the U.S. and Canada is only a fraction of what is funded for the oceans.”

Technology tracks bee talk to help improve honey bee health

Simon Fraser University graduate student Oldooz Pooyanfar is monitoring what more than 20,000 honeybees housed in hives in a Cloverdale field are “saying” to each other—looking for clues about their health. 

Pooyanfar’s technology is gleaning communication details from sound within the hives with her beehive monitoring system—technology she developed at SFU. She says improving knowledge about hone

Tiny terahertz laser could be used for imaging, chemical detection

Terahertz radiation — the band of the electromagnetic spectrum between microwaves and visible light — has promising applications in medical and industrial imaging and chemical detection, among other uses.

But many of those applications depend on small, power-efficient sources of terahertz rays, and the standard method for producing them involves a bulky, power-hungry, tabletop device.

For more than 20 years, Qing Hu, a distinguished professor of electrical engineering and computer science at MIT, and his group have been working on sources of terahertz radiation that can be etched onto microchips. In the latest issue of Nature Photonics, members of Hu’s group and colleagues at Sandia National Laboratories and the University of Toronto describe a novel design that boosts the power output of chip-mounted terahertz lasers by 80 percent.

Cooking up new ways to clean up our planet

In a win-win for a cleaner planet, scientists have devised a way to use waste cooking oil and sulphur to extract the neurotoxin mercury from the environment.

For the first time, researchers have demonstrated that the dynamic new canola oil polymer can trap the most dangerous and common types of mercury pollution – mercury metal, mercury vapour and highly toxic organo-mercury compounds which harm both aquatic and terrestrial systems.

Not all Glaciers in Antarctica Have Been Affected by Climate Change

A new study by scientists at Portland State University and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder has found that the effects of climate change, which are apparent in other parts of the Antarctic continent, are not yet observed for glaciers in the western Ross Sea coast.

Published online ahead of print for the journal Geology, the study found that the pattern of glacier advance and retreat has not changed along the western Ross Sea coast, in contrast to the rapidly shrinking glaciers on the Antarctic Peninsula.

Virginia Tech researchers discover potentially harmful airborne nanoparticles produced through burning of coal

Environmental scientists led by the Virginia Tech College of Science have discovered that the burning of coal produces incredibly small particles of a highly unusual form of titanium oxide.

Annual Wind Power Report Confirms Technology Advancements, Improved Project Performance, and Low Wind Energy Prices

Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the U.S. Department of Energy and prepared by the Lawrence Berkeley National Laboratory (Berkeley Lab). Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.

New ultrafast method for determining antibiotic resistance

Researchers at Uppsala University have developed a new method for very rapidly determining whether infection-causing bacteria are resistant or susceptible to antibiotics. The findings have now been published in the US journal Proceedings of the National Academy of Sciences (PNAS).

Distributed wind power keeps spinning, growing

Both businesses and homeowners are increasingly using distributed wind power thanks to innovative business models and other trends, according to a new report released today.
