    Oil spill experience often shows that response activities are hampered due to the absence of operative autonomous support capable of reaching particular sites or operate in safe and efficient conditions in areas such as saltmarshes, mudflats, river banks, cliff bottoms… This is the purpose of the so-called FP7 Hoverspill project (www.hoverspill.eu), a 3-year European project that recently reached completion: to design and build a small-size amphibious vehicle designed to ensure rapid oil spill response. The result is an air-cushion vehicle (ACV), known as Hoverspill, based on the innovative MACP (Multipurpose Air Cushion Platform) developed by Hovertech and SOA. It is a completely amphibious vehicle capable of working on land and on water, usable as a pontoon in floating conditions. Its compactness makes it easy to transport by road. The project also included the design and building of a highly effective integrated O/W Turbylec separator developed by YLEC. Spill response equipment will be loaded on-board based on a modular concept enabling the vehicle to carry out specific tasks with just the required equipmen

    Evaluation of a New System Combining Wood-Burning Stove, Flue Gas Heat Exchanger and Mechanical Ventilation with Heat Recovery in Highly-Insulated Houses

    The performance of an innovative flue gas heat exchanger (FGHE) located at the exit of a wood-burning stove (log or pellet) to pre-heat ventilation air has been assessed for highly insulated detached houses. For this purpose, transient thermal simulations (TRNSYS + TRNFlow) were carried out on a Norwegian house typology (passive house standard NS3700) and a French house typology (building regulation RT2012) – both equipped with mechanical ventilation systems with heat recovery (MVHR). Seven different climates were considered ranging from mixed (Nice, France) to subarctic conditions (Karasjok, Norway) in order to evaluate the impact of the system in terms of energy use for space-heating and thermal comfort for a broad range of operating conditions. The tested system allowed an improvement of the thermal comfort in the bedrooms furthest away from the stove: up to 7.6 °C of the 5th percentile of the operative temperature (Top 5%) for France and up to 9.5 °C for Norway, compared to the houses without the system. Furthermore, energy savings of up to 19% over the space-heating season were reported, depending on the type of wood-burning stove (i.e. log or pellet) and control used during operation.© 2019 Elsevier B.V.
