The Earth Institute at Columbia University -- With oil prices reaching near near-record highs in recent weeks, calls have grown louder for the U.S. to develop new sources of affordable, domestic energy. Work by experts from The Earth Institute at Columbia University suggests that relatively low-cost alternatives already exist to meet the country’s’ growing energy demand that would at the same time reduce the need to rely on oil supplies from the Middle East and Latin America.
A report published by Klaus S. Lackner and Jeffrey D. Sachs of The Earth Institute at Columbia University that appears in the most recent issue of Brookings Papers on Economic Activity states that coal alone could satisfy the country’s energy needs of the twenty-first century. In particular, coal liquefaction, or the process of deriving liquid fuels from coal, is already being used in places and with expanded infrastructure could provide gasoline, diesel fuel and jet fuel at levels well below current prices. Moreover, they argue that environmental constraints such as increased carbon dioxide emissions arising from greater use of coal and other fossil fuels could be avoided for less than 1 percent of gross world product by 2050.
"[With widespread use of coal liquefaction] the long-term price of liquid hydrocarbon fuels may be lower than it is today, even allowing for pessimistic forecasts for oil and gas reserves," the authors write. "Even with the most conservative assumptions about learning curves, it appears quite safe to predict that the cost of synthetic oil from coal or other processes, after some transitional pains, will be below $30 per barrel." Sachs and Lackner also point out that the large deposits of coal in the U.S. and worldwide make it less prone to the political uncertainties that currently afflict world oil prices.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
