During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The last panel of the day focused on energy/environmental solutions and the innovation behind four R&D 100-winning technologies and the complexity of bringing such technologies to the market.
Natural gas power plants produce substantial amounts of gases that lead to global warming. Replacing old coal-fired power plants with new natural gas plants could cause climate damage to increase over the next decades, unless their methane leakage rates are very low and the new power plants are very efficient.
A new study by researchers at the Univ. of Exeter has found early warning signals of a reorganization of the Atlantic oceans’ circulation which could have a profound impact on the global climate system. The researchused a simulation from a highly complex model to analyze the Atlantic Meridional Overturning Circulation, an important component of the Earth’s climate system.
Before it can put the party in party balloons, helium is carried from deep within the Earth’s crust to the surface via aquifers. Aquifers contain water that has filtered there over hundreds of millennia. Using an atom trap built at Argonne National Laboratory to date the water in a deep South American aquifer, scientists tracked the rate at which helium pooled in the aquifers.
A groundbreaking research project by the GW4 Alliance aims to clean up water from a Cornish tin mine, using algae to harvest the precious heavy metals and produce biofuel at the same time. GW4 brings together the South West and Wales’ four leading, research-intensive universities: Bath, Bristol, Cardiff and Exeter.
Hydrocarbon exploration by definition is the search by geologists or geophysicists for hydrocarbon deposits beneath the Earth’s surface, such as oil (petroleum) and natural gas. In such exploration, the oil and gas industry drills holes into the Earth’s surface to extract the petroleum or natural gas. However, such exploration is expensive, not to mention a high-risk operation.
Rice Univ. scientists have discovered an environmentally friendly carbon-capture method that could be equally adept at drawing carbon dioxide emissions from industrial flue gases and natural gas wells. The Rice laboratory of chemist Andrew Barron revealed in a proof-of-concept study that amine-rich compounds are highly effective at capturing the greenhouse gas when combined with carbon-60 molecules.
New research shows that relatively small volcanic eruptions can increase aerosol particles in the atmosphere, temporarily mitigating the global warming caused by greenhouse gases. The impact of such smaller eruptions has been underestimated in climate models, the researchers say, and helps to account for a discrepancy between those models and the actual temperatures observed over the last 15 years.
It takes just 10 years for a single emission of carbon dioxide to have its maximum warming effects on the Earth. This is according to researchers at the Carnegie Institute for Science who have dispelled a common misconception that the main warming effects from a carbon dioxide emission will not be felt for several decades.
Declaring the "fight is nowhere close to being over," President Barack Obama on Tuesday heralded strides in the effort to confront Ebola in West Africa and in protecting the U.S. against the spread of the deadly virus. He said squelching the disease remains an urgent priority even if the American public's attention has shifted elsewhere.
Chemists and engineers at Oregon State Univ. have discovered a fascinating new way to take some of the atmospheric carbon dioxide that’s causing the greenhouse effect and use it to make an advanced, high-value material for use in energy storage products. This innovation in nanotechnology won’t soak up enough carbon to solve global warming, but it will provide a low-cost way to make nanoporous graphene for use in supercapacitors.
Microbes of interest to clinicians and environmental scientists rarely exist in isolation. Organisms essential to breaking down pollutants or causing illness live in complex communities, and separating one microbe from hundreds of companion species can be challenging for researchers seeking to understand environmental issues or disease processes.
As much as two-thirds of Earth's carbon may be hidden in the inner core, making it the planet's largest carbon reservoir, according to a new model that even its backers acknowledge is "provocative and speculative." In a recent paper, Univ. of Michigan researchers and their colleagues suggest that iron carbide, Fe7C3, provides a good match for the density and sound velocities of Earth's inner core under the relevant conditions.
A National Science Foundation-funded research team has successfully tested an autonomous underwater vehicle (AUV) that can produce high-resolution, 3-D maps of Antarctic sea ice. SeaBED, as the vehicle is known, measured and mapped the underside of sea-ice floes in three areas off the Antarctic Peninsula that were previously inaccessible.
Fluorocarbon, a generic term for organic compounds with carbon-fluorine (C-F) bonding, is a chemical material used as a refrigerant in refrigerators and freezers and air conditioners in cars, buses, other vehicles and buildings. It’s also used as a cleaning agent for electronic components and precision parts.
Farmers interested in bioenergy crops now have a resource to help them determine which kind of bioenergy crop would grow best in their regions and what kind of harvest to expect. Researchers at the Univ. of Illinois have published a study identifying yield zones for three major bioenergy crops.
Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory (LLNL) scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.
In a study that identifies a new, "direct fingerprint" of human activity on Earth, scientists have found that agricultural crops play a big role in seasonal swings of carbon dioxide in the atmosphere. The new findings from Boston Univ., the Univ. of Michigan and other institutions reveal a nuance in the carbon cycle that could help scientists understand and predict how Earth's vegetation will react as the globe warms.
The R&D 100 Awards have a 50+ year history of recognizing excellence in innovation, earning the name the “Oscars of Invention." And at the annual event, the high rollers of the science and technology industry were honored on stage for their innovative, high-tech products and processes that are, or will, make a difference in our everyday lives.
Engineers have created a new way to use lidar technology to identify and classify landslides on a landscape scale, which may revolutionize the understanding of landslides in the U.S. and reveal them to be far more common and hazardous than often understood. The new, non-subjective technology can analyze and classify the landslide risk in an area of 50 or more square miles in about 30 mins.
The world still isn't close to preventing what leaders call a dangerous level of man-made warming, a new United Nations report says. That's despite some nations' recent pledges to cut back on carbon dioxide emissions. The report looks at the gap between what countries promise to do about carbon pollution and what scientists say needs to be done to prevent temperatures rising another two degrees.
Truth shines a light into dark places. But sometimes to find that truth in the first place, it’s better to stay in the dark. That’s what recent findings at NIST show about methods for testing the safety of nanoparticles. It turns out that previous tests indicating that some nanoparticles can damage our DNA may have been skewed by inadvertent light exposure in the lab.
Reducing greenhouse gas (GHG) emissions, which result from the burning of fossil fuels, also reduces the incidence of health problems from particulate matter (PM) in these emissions. A team of scientists has calculated that the economic benefit of reduced health impacts from GHG reduction strategies in the U.S. range between $6 and $14 billion annually in 2020, depending on how the reductions are accomplished.
An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres.
Here’s another reason to pay close attention to microbes: Current climate models probably overestimate the amount of carbon that will be released from soil into the atmosphere as global temperatures rise, according to research from Lawrence Berkeley National Laboratory. The findings are from a new computer model that explores the feedbacks between soil carbon and climate change.
