In 2002, nuclear engineers Rusi P. Taleyarkhan of Purdue University and Richard T. Lahey Jr. of Rensselaer Polytechnic Institute announced that they had produced thermonuclear fusion by imploding tiny deuterium-rich gas bubbles with sound waves and neutrons. The news about their fusion method--dubbed sonofusion--made headlines worldwide. Yet many skeptics greeted it with scoffing. Now, after repeating the experiments with an improved apparatus, Taleyarkhan and Lahey have more convincing evidence.
In the May 2005 issue of IEEE Spectrum, they discuss their latest experiments in detail and also explain how they plan to turn their tabletop apparatus into a full-scale electricity-generating device. "If this proves possible--and its still a big if--sonofusion could become a revolutionary new energy source," they write.
They also say that other groups may soon have new findings to confirm that sonofusion works. "Now at least five groups--three in the United States and two in Europe--are working on reproducing our sonofusion results," they write. "Some have apparently already succeeded and are now preparing to publish their findings."

It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries
20.08.2018 | Forschungszentrum Jülich
There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
