Wind speed information greatly improves risk minimisation in the planning, construction and operation phases of offshore wind farms. When compared with measuring masts, the buoy has one decisive advantage:
The Fraunhofer IWES’ LiDAR wind-measuring buoy was successfully installed near the FINO1 meteorological mast. The buoy measures wind speeds at heights of 40 to 200 m.

It can be employed at any location with no extra installation costs and requires a less time-consuming authorization procedure. This is all made possible by a correction algorithm developed at the Fraunhofer IWES.
A validated technology conquers new terrain: Using LiDAR (“Light Detection And Ranging”) appliances on land and on fixed platforms for measuring wind speeds at heights of 40 to 200 m are a proven process. Proper motion, which falsifies measurement values taken from moving surfaces, has hitherto hindered the reliable employment of LiDAR applications offshore. Within the framework of the project “Offshore Measuring Buoy” – funded by the German Federal Ministry for the Environment – Fraunhofer scientists are now extremely excited about the first North Sea deployment of the gloating LiDAR system. A Windcube LiDAR device made by the company Leosphere has been integrated into the buoy.
Rapid implementation and marked cost reductions through floating LiDAR technology should make it possible for wind farm developers to reduce the actual costs of offshore wind energy. The construction of an authorized measuring mast such as FINO1 requires a double-digit million investment. The data quality of mast and buoy should be comparable.High Data Quality Despite Floating Platform:

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
