  2. 1. Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy

    Author : Randi Phinney; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pervaporation; solar drying; membrane pouch; juice concentration; fruit preservation; marmalade; tangerine; Vangueria infausta; microbiology; water activity; soluble solids; Brix;

    Abstract : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. READ MORE

  4. 2. Energy Efficiency through Thermal Energy Storage : Possibilities for the Swedish Building Stock

    Author : Johan Heier; Viktoria Martin; Chris Bales; Signhild Gehlin; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Abstract : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. READ MORE

  5. 3. Modelling of  Ocean Wave Energy Conversion for Increased Power Absorption

    Author : Tatiana Potapenko; Irina Temiz; Cecilia Boström; Sandra Eriksson; Felice Arena; Uppsala universitet; []
    Keywords : ;

    Abstract : The Earth is also called the blue planet, because more than 70 % of its surface is covered by water, mainly in oceans and seas. Wind blowing over the oceans is creating water waves, which can travel thousands of kilometers with just a small energy loss. READ MORE

  6. 4. Wave energy converter: hydrodynamics and control

    Author : Tatiana Potapenko; Irina Temiz; Cecilia Boström; Sandra Eriksson; Halvar Gravråkmo; Uppsala universitet; []
    Keywords : ;

    Abstract : Waves, just like wind and solar radiation, is a widely available renewable energy source. Waves are created when winds move across the sea surface. The estimated potential of wave energy is abundant, but the commercial harvesting technologies are still in their infancy. READ MORE
