Denmark: The first test of superconducting wind turbines succeeds
The superconducting generator was successfully tested on an active wind turbine for the first time. EcoSwing Group designed, developed, and manufactured full-size superconducting generators for 3.6MW wind turbines, and conducted field tests in Tiburon, Denmark. Their research results were published in the journal "Superconductor Science and Technology" published by IOP. Corresponding author Anne Bergen from the University of Twente in the Netherlands said: "In the past few decades, the volume of wind turbines has grown significantly. However, today's technology is difficult to keep up with the growing unit power level. trend." Direct-drive (DD) generators based on permanent magnets (PM) provide a state-of-the-art solution for multi-megawatt generators, but permanent magnet direct-drive generators above 10MW require weight reduction. Pseudo-electromagnetic direct drive (PDD) motors, which integrate electromagnetic drive and generator functions, are a feasible method to solve this problem, but they will bring expensive cost and highly complicated production process. To meet this challenge, the team used a rare earth barium copper oxide (ReBCO) high temperature superconducting generator. Compared with permanent magnet generators, these devices only require a small amount of rare earth materials, so the cost is lower. Superconductors can also carry high current density, resulting in greater power and lighter weight. Bergen said: “The field test of the generator was very successful. When the generator was installed in Tiburon, the turbine achieved its target power range, including more than 650 hours of grid-connected operation time. This shows the technology and operation of superconducting generators Compatibility of all elements of the environment (such as variable speeds, grid faults, electromagnetic harmonics and vibration) ". The project also made several other substantial progress. It shows that the production of high-temperature superconducting coils is not limited to professional laboratories, and has achieved a successful transfer from scientific research and development to industry. "Now that the concept has been proven, we hope to see superconducting generator technology begin to be widely used in wind power generation."

The Fiber Optic Sauna Ceiling light are safe for use in wet and humid areas as no heat or electricity is present in the fibre optics or fittings, but the illuminator which contains the electricity, must be located outside the main sauna or steam room.
Sauna lighting is something of a specialist field. This is because the heat of the sauna will cause most traditional light sources to fail. To illuminate a sauna safely and effectively, one must either use a fibre-optic lighting system, or use specialist sauna LED's. Furthermore, getting the light levels and in turn the ambiance in the sauna right, is crucial to the enjoyment of the sauna itself.
