Making a better invisibility cloak

The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ties up one of the ...

Bose-Einstein condensate: Magnetic particles behave repulsively

Data transmission that works by means of magnetic waves instead of electric currents: For many scientists, this is the basis of future technologies that will make transmission faster and individual components smaller and ...

Successful tests of a cooler way to transport electricity

Like a metal python, the huge pipe snaking through a CERN high-tech hall is actually a new electrical transmission line. This superconducting line is the first of its kind and allows vast quantities of electrical current ...

With changes, the grid can take it

Over the next two decades, the U.S. electric grid will face unprecedented technological challenges stemming from the growth of distributed and intermittent new energy sources such as solar and wind power, as well as an expected ...

Robots designed to inspect power lines

(PhysOrg.com) -- Overhead transmission lines traverse thousands of kilometers, often crossing remote areas. Inspecting the often ageing lines and the vegetation near them is an important aspect of maintenance, but it can ...
