mref, ases, and sbse meetings in june 30 apr 2000 dbarley@ases.org writes: join us in madison, wisconsin for the solar 2000 conference june 16-21, 2000 early registration deadline is may 3 -- register now to get the best rates! you can register on-line at: http://www.ases.org/solar2000/register.php3 general conference information including the preliminary program is posted at: http://www.ases.org/solar2000/index.html information on the midwest renewable energy fair is posted at: http://www.the-mrea.org/ presented by: american solar energy society american institute of architects committee on the environment american society of mechanical engineers solar energy division interstate renewable energy council hosted by: midwest renewable energy association the society of building science educators will meet from june 21-24 at nearby taliesin, wi, after ases... http://www.polaris.net/~sbse.web/ dr. richard komp will be giving an ases talk about a pgv/still that uses the waste heat to evaporate sea water to produce fresh water: the photovoltaic still: desalinate sea water and make electricity at the same time richard komp sunwatt corporation rr 2 box 7751 jonesport me 04649 sunwatt@juno.com susan kinne douglas garcia alternative sources of energy project universidad nacional de ingenieria managua, nicaragua skinne1@juno.com abstract the photovoltaic still is a device that uses the evaporation of sea water to cool solar cells, to make the photovoltaic cells operate more efficiently while at the same time condensing the water vapor into fresh water. we have succeeded in constructing and testing the first prototype pv/still. the small, 30 cm by 125 cm device has a rated electric output of only 18 watts, but is of sufficient size to demonstrate the concept of using evaporative cooling to increase the electrical output of a 2 to 1 concentrator photovoltaic device, while at the same time condensing the water vapor to recover fresh water from sea water. preliminary measurements made of the performance of the still show the cell temperature dropping after introduction of the sea water and the production of distilled water. the concentrated brine is removed separately and evaporated to recover the sea salt. nick |
