		<description><![CDATA[Designed by C. F. Møller Architects in cooperation with Moe &#038; Brødsgaard, Cenergia, Phillips, Schüco, Erik Juul and Vogt landscape, the Housing+ is a passive housing that supports on-site renewable energy generation. Located around Aalborg waterfront in Denmark, the pilot-project features a long sloping elevation, which provides a plane for a 1200 m2 solar array to produce the 104.400 kwh of electricity (annually) to power 60 housing units without external resources. The sustainable housing uses the fjord to power heat pumps, while a highly insulated water-tank (W 3 x H 12 m) is integrated to store the solar energy. Apart from solar array and heat pump, the housing project also integrates 4 vertical low-noise wind turbines that generate energy to recharge electric cars. Moreover, the slope shelters a public gazebo and cafe for community gatherings.]]></description>

One of the options is compressed-air storage; till now only possible in underground caverns. But SustainX Energy Solutions; a Dartmouth College start-up  that got $4 million in VC funding from Polaris Venture Partners and Rockport Capital this year is working on compressing and storing air in cheap off-the-shelf shipping containers.]]></description>

They will present their concept at the 62nd Annual Meeting of the American Physical Society&#8217;s (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneapolis Convention Center.</strong></p>
<p>About a half-inch by one inch in size, these devices might be mounted on the roof or tail of a car or on an airplane fuselage where they would vibrate inside a flow, producing an output voltage. The power generated would not be enough to replace that supplied by the combustion engines, but it could run some system &#8212; such as batteries that would be used to charge control panels and other small electronic devices such as mobile phones.</p>
<p>Led by CCNY professor Yiannis Andreopoulos, the researchers are currently attempting to optimize these devices by modeling the physical forces to which they are subjected in different air flows &#8212; on the roof of a car, for instance, or on the back of a truck.</p>
<p>When the device is placed in the wake of a cylinder &#8212; such as on the back of a truck &#8212; the flow of air will cause the devices to vibrate in resonance, says Andreopoulos. On the roof of car, they will shake in a much more unsteady flow known as a turbulent boundary layer. In Minneapolis, Andreopoulos and his colleagues will present wind tunnel data showing how the devices work in both situations.</p>
<p>&#8220;These devices open the possibility to continuously scavenge otherwise wasted energy from the environment,&#8221; says Andreopoulos.</p>
<p>The presentation, &#8220;Harvesting energy in the wake of a circular cylinder using piezoelectric materials&#8221; by Dogus H. Akaydin, Niell Elvin, and Yiannis Andreopoulos of the City College of New York is on November 22, 2009.</p>

Start uga_filter: <p><strong>Within the Consolider HOPE project (projects funded by the Ministry of Innovation and Science), a group of scientists at Universidad Pablo de Olavide (UPO), headed by Juan Antonio Anta, are working on the optimisation of a type of photovoltaic cell (Grätzel cell) that artificially mimics photosynthesis.</strong></p>
<p>Grätzel cells are photovoltaic devices that take advantage of the interaction of a structured semiconductor less than nanometre in size and an organic dye that acts as a solar collector.</p>
<p>According to Elena Guillén, member of UPO&#8217;s Coloides y Celdas Solares Nanoestructuradas (Nanostructured Colloids and Solar Cells) Group, this dye can be either synthetic or natural and can even enable the use of chlorophyll for this type of cell.</p>
<p>Thus, researchers at UPO have begun a study with which they hope to increase the efficiency of these eosin or mercurochrome -based organic components by incorporating ionic salts, known as green solvents, with a view to preventing evaporation of the liquid compounds and the consequent reduction in efficiency.</p>
<p>Previous studies show that ionic salts are less volatile and it is this characteristic that the group headed by Professor Anta seeks to exploit. &#8220;Notwithstanding its liquid state, these types of solvents have high viscosity levels and, therefore, during the coming months we will continue our study, working on different alternatives within ionic liquids, their synthesis, etc.,&#8221; comments Elena Guillén.</p>
<p><strong>The pros and cons of the new generation</strong></p>
<p>Although there are already some third generation cells on the market (for example, for recharging mobile phones), according to the researchers their practical use is anecdotal. However, due to their properties of flexibility and variety of colours and shapes, the future of these cells lies in new market niches such as decoration or use in coloured windows that not only allow light through but use this light to generate electricity.</p>
<p>On the other hand, apart from the rapid amortisation of energy production costs -estimated in one year&#8217;s use-, there is also the low cost of the materials. &#8220;Organic materials are usually cheaper,&#8221; affirms the researcher, despite which the search continues for an alternative organic dye to the one currently used, derived from ruthenium.</p>
<p>&#8220;The paradox lies in the fact that if one uses these cells because their competitive edge is that they are cheaper and more readily available, and then one uses a dye based on a precious metal, what is the advantage?&#8221; points out Elena Guillén.</p>
<p>On the other hand, the researchers are aware that it is a relatively new technology -this type of cell was invented in 1991- that still need to be greatly developed. Furthermore, the maximum efficiency obtained in laboratory is only 11%, which is competitive but it drops when extrapolated to an industrial scale.</p>
<p>The main technological challenge is currently the problem of cell degradation. &#8220;If you use an organic dye, it can be degraded by the action of sunlight, with the consequent reduction in useful life compared to silicon cells. On the other hand,&#8221; the researcher highlights, &#8220;our group is working on one of the key aspect for improving cell stability &#8211; elimination of the need to use liquids that can present problems with evaporation, etc. and for which, as already mentioned, our focus is on the use of ionic salts.&#8221;</p>
