The main objective of the project was to find a cheap and ecological solution for producing drinking water for the water stressed islands of the Aegean by integrating a desalination unit with wind power in the same structure. The project also set out to: reduce the costs of connection between the desalination unit and the wind turbine due to the absence of a network for transferring energy offer the possibility of locating the platform far from populated areas in order to minimize disturbance linked to noise offer the possibility of moving the unit to different areas for optimal use depending on weather conditions The system developed is environmental friendly and autonomous, meaning that the floating platform operates unmanned, that energy comes from renewable sources and that it does not have any adverse side effects. From an operational point of view, drinking water is produced from the seawater desalination unit with energy provided by a wind generator and photovoltaic system.

Bei der Membrandestillation handelt es sich um ein thermisch getriebenes Separationsverfahren, bei dem die Separation aufgrund eines Phasenwechsels erfolgt. Eine hydrophobe Membran stellt hierbei eine Barriere für die flüssige Phase (z. B. Salzwasser) eines Fluidstroms dar, die dampfförmige Phase (z. B.

The active materials in redox-flow batteries are dissolved salts in liquid electrolytes. The electrolyte is stored in tanks and is pumped for charging and discharging into a central reaction unit. Unfortunately the equilibrium concentration of most of the salts is low and therefore the volumetric energy density is comparable with lead-acid batteries.

Flow battery
A flow battery is a rechargeable fuel cell in which electrolyte containing one or more dissolved electroactive species flows through an electrochemical cell that reversibly converts chemical energy directly to electricity . Additional electrolyte is stored externally, generally in tanks, and is usually pumped through the cell (or cells) of the reactor, although gravity feed systems are also known. [1] Flow batteries can be rapidly "recharged" by replacing the electrolyte liquid (in a similar way to refilling fuel tanks for internal combustion engines ) while simultaneously recovering the spent material for re-energization.

Im Mittelpunkt des Projektes steht die effektive Verwertung von Rest- und Abfallstoffen im Botanischen Garten Berlin. Als Rest- und Abfallstoffe zählen im Botanischen Garten u.a. Laub, Rasen-, Baum- und Strauchschnitt. Ziel dabei ist es, einen wesentlichen Beitrag zum nachhaltigen Bodenmanagement im Bereich des Urban farming auch unter dem Blickwinkel der Vermeidung von Kohlenstoff- und Nährstoffverlusten und der Anpassung an die Folgen der Klimaveränderungsprozesse zu leisten.

Biotechnik gegen Klimakiller: Algen sollen Treibhausgas fressen
Wissen Donnerstag, 22. Juli 2010 Im Braunkohlekraftwerk Senftenberg testet Vattenfall Algen im Kampf gegen CO2. Verlaufen die Tests positiv, könnte das ein Durchbruch im Kampf gegen den Klimawandel sein. Mit einem trägen Gluckern steigen Blasen in der trüben dunkelgrünen Algenbrühe nach oben.Als EE-Gas wird ein Brenngas bezeichnet, welches mittels Elektrolyse unter dem Einsatz von Strom aus erneuerbaren Energien (EE) hergestellt wird. [1] Je nach Art der eingesetzten erneuerbaren Energie wird das Gas auch Windgas , Solargas oder ähnlich genannt, je nach chemischer Zusammensetzung des Gases wird statt des Begriffes „Gas“ auch „ Methan “ oder „ Wasserstoff “ verwendet.

The challenge - SolarFuel GmbH - Electricity from renewable sources
Only the large-scale storage of energy can reliably secure an economic supply from renewable sources. The amount of electricity being generated from the wind and the sun is increasing the world over. One problem is the lack of electricity storage facilities for green electricity, which is generated at irregular intervals, since wind and solar power is often produced at times when it is not needed. In collaboration with leading German research institutes, SolarFuel has succeeded in converting renewable electricity into synthetic natural gas, thus enabling it to be stored.A selection of dye-sensitized solar cells A dye-sensitized solar cell ( DSSC , DSC or DYSC [ 1 ] ) is a low-cost solar cell belonging to the group of thin film solar cells . [ 2 ] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte , a photoelectrochemical system. The modern version of a dye solar cell, also known as the Grätzel cell, was originally co-invented in 1988 by Brian O'Regan and Michael Grätzel at UC Berkeley [ 3 ] and this work was later developed by the aforementioned scientists at the École Polytechnique Fédérale de Lausanne until the publication of the first high efficiency DSSC in 1991. [ 4 ] Michael Grätzel has been awarded the 2010 Millennium Technology Prize for this invention. [ 5 ]
