The U.S. Government is spending millions of dollars to research the feasibility of stuffing carbon dioxide into coal seams and fields of briny water deep beneath the Earth. But, a scientist at the American Association for the Advancement of Science (AAAS) Annual Meeting argues that the government isnt thinking big enough in its plans to remove carbon dioxide from the atmosphere.
Dissatisfied with the long-term potential of most current technologies for carbon sequestration, Klaus Lackner, Ewing-Worzel Professor of Geophysics at Columbia University, has designs for new power plants that would capture carbon dioxide before it leaves the facility, as well as for "synthetic trees" that would pluck carbon from the air, mix it with magnesium silicate, and store the carbon in the "rocks" that would result from the chemical interaction between the elements.
"Injecting carbon underground is a short-term solution," Lackner said. "The oil industry has done this with 20 million tons a year in West Texas, but that is not the scale were talking about here. We need to find a way to put away 20 billion tons." The Intergovernmental Panel on Climate Change has estimated that worldwide carbon dioxide emissions could more than triple over the next 100 years, from 7.4 billion tons of carbon per year in 1997 to approximately 20 billion tons per year by 2100. Lackner argued that large-scale carbon sequestration would allow the continued use of carbon-based fuels during the time needed to develop alternative sources of energy.

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.
Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...
An international team of scientists involving the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.
The researchers from ETH Zurich (Switzerland), the MPSD (Germany), the Center for Computational Sciences of University of Tsukuba (Japan) and the Center for...
