The “Lark” Is Waiting For The Wind

27.02.2006


Electric power is needed in remote regions difficult of access, settlements, expeditions and at timber-felling. Where can it be obtained from? Specially for such occasions, researchers from the Moscow Institute of Heating Engineering have invented a wind turbine, which can be delivered by car in a container or by helicopter, for example, MI-26 at external load. The developers promise that the device would supply energy without interruption. “What about dead calm weather?” – you would ask. In this case, the second part of the wind turbine will start working – Diesel generator.



The both devices ensure capacity of 30 kW each. When there is no wind, the Diesel is working, when the wind is gentle, both devices are operating. The LARK’s control algorithm is built in such a way that maximum of energy is collected by the wind turbine from the wind, and the missing part is added by the Diesel. The windwheel diameter is ten meters, it is able of whirling without interruption for twenty five years!

Moreover, the system is fully automated and does not require operations staff’s permanent presence. But the most interesting thing about it is that the device does not require building the foundation, in contrast to ordinary wind turbines. In the regions difficult of access, where stand-alone power sources are needed, construction of the foundation is comparable to the wind turbine itself in terms of cost.


It is only necessary to deliver the LARK wind turbine to the destination, to unload the device,and it will turn downwind with the help of horizon scanners. That is, the wind turbine is a factory-assembled device, which does not require foundation construction, assembly work and balancing and commissioning. Its price is about USD two hundred thousand.

“Two devices have already passed a complete trial cycle, received certificates of conformance, they have been patented, full-scale production is being prepared in Moscow. Buyers are already in place. By the way, the LARK wind turbine received diplomas at the International exhibitions in Brussels “Eureka–97” and in Geneva in 2000”, said operations manager Valery Kisilev.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
