SUPRAPOWER Project to Develop Superconductor Wind Turbines for EU

Despite the clean energy provided by wind turbines, they remain expensive to build and install, especially the offshore type. To help reduce this cost, the EU together with nine more companies and science groups and led by Spain’s Tecnalia, have unveiled a project to develop superconductor technology for wind turbines. The entire project is to [...]

Solar Cells and Supercapacitors Improved by New 3D Germanium Sulfide Nanostructure

Next-generation supercapacitors and solar cells could be improved by a newly-created germanium sulfide (GeS) nanomaterial resembling a shish-kebab. North Carolina State University researchers put up a three-dimensional structure that consists of multiple bi-dimensional nanosheets impaled by a one-dimensional nanowire  of germanium sulfide. To create the heterosurface, the researchers begin by creating the nanowire 100 nanometers [...]

Uranium-Based Material Could Lead to Better Superconductors

Mention uranium, and you may think of two applications right off the bat, nuclear power generation and atomic weapons. These two things may bring some problems to mind, such as nuclear meltdown, fallout, and winter. Physicists, on the other hand, don’t see things quite so dismally, and continue to experiment with uranium for more benign [...]

Superconductors Could Increase Wind Turbine Efficiency

One of the great limitations in any electrical or electronic system is resistance. Electrical resistance, measured in “Ω” or ohms, is not a constant, but dependent on temperature. As the temperature increases, resistance also increases. When considering wind turbine generators, there are limits to the amount of electricity can be generated. The problem is that [...]

Superconducting Generators Increase Wind Power Plant Efficiency

Experts believe that wind power will be the key in the quest for alternative energy solutions. After years of research, scientists have determined that adding superconductors to generators will increase the performance and generate 10 megawatts while also reducing the weight and size of the generator. Superconducting generators also use a fraction of the globes’ [...]

Atom Cooling Leads to Greater Understanding of Superconductors

The processes that occur when atoms cool have long eluded scientists. However, a team of researchers at The Open University believe they have developed a method to understand more about the specifics of atom cooling and hope this may one day be used to more sophisticated superconductors. A superconductor is a material with no electrical [...]

SMES: New Energy Storing Technology by ABB Using Electromagnetic Fields and Superconductivity

ABB, a Swiss-based engineering company, has presented a prototype of their innovative superconducting magnetic energy storage (SMES), at a DOE ARPA-E conference which took place in Washigton D.C. at the beginning of this month. Their 3.3 kWh proof-of-concept SMES is not very cost-effective for the moment, but may one day provide cleaner storage solutions for excess alternative energy.

Scientists Explain Limitations of High Temperature Superconductors in High Currents

Since their discovery in late 1980s, superconductors were thought to revolutionize everything that had an electric current flowing, but allowing it to pass through more easily, and with much less heat produced. Ultra-efficient magnetic trains had been envisioned, then, but …

Scientists Discover Nano-Scale Superconducting Material

Researchers from the Bar-Ilan University in Israel, collaborating with the Brookhaven National Laboratory in the U.S. have designed superconducting thin films patterned with large arrays of nanowires and loops. The temperature at which they superconduct is pretty low and hard to get for the moment – only 30 °K (-243°C). Magnetic fields have proved themselves to change the material’s electrical resistance in an unexpected manner.
