The Clean Energy project - computação distribuida e pesquisa
Enviado: terça abr 14, 2009 9:43 am
bons dias a todos,
venho apresentar aqui, a quem tenha interesse na pesquisa de novas tecnologias de produção fotovoltaica, e que queira participar.
este projecto é mais um dos projectos de computação distribuida existentes na net.
no entanto é muito interessante, quando pensamos que uma celula fotovoltaica demora 12 anos a produzir a energia gasta no seu fabrico, os custos de aquisição e instalação e retorno do investimento.
o projecto "the clean energy project" é desenvolvido pela universidade de harvard e corre atraves da world community grid, que mantem para além deste projecto, outros de pesquisa para cura de cancro, distrofia muscular, e inclusivamente do hiv.
resumindo (para não estar a traduzir tudo) o objectivo do projecto é pesquizar entre milhares de milhares de compostos quimicos, os mais promissores que possam substituir o silicio como elemento de produção de electricidade e assim proporcionar o fabrico muito barato de celulas de produção de energia, baseada em polimeros (plastico?).
a segunda fase do projecto irá pesquisar formas de acumulação da energia produzida e adequado fornecimento (descarga), também a partir de formas alternativas (e eventualmente desconhecidas até ao momento) substituindo os acumuladores sobejamente conhecidos de forma a que esse lado do sistema de geração seja também barato!
acho o conceito da pesquisa fantastico e já tenho os meus pc a participar!

" mission
the mission of the clean energy project is to find new materials for the next generation of solar cells and later, energy storage devices. by harnessing the immense power of world community grid, researchers can calculate the electronic properties of tens of thousands of organic materials – many more than could ever be tested in a lab – and determine which candidates are most promising for developing affordable solar energy technology.
significance
we are living in the age of energy. the fossil fuel based economy of the present must give way to the renewable energy based economy of the future, but getting there is the greatest challenge humanity faces. chemistry can help meet this challenge by discovering new materials that efficiently harvest solar radiation, store energy for later use, and reconvert the stored energy when needed.
the clean energy project uses computational chemistry and the willingness of people to help look for the best molecules possible for: organic photovoltaics to provide inexpensive solar cells, polymers for the membranes used in fuel cells for electricity generation, and how best to assemble the molecules to make those devices. by helping us search combinatorially among thousands of potential systems, world community grid volunteers are contributing to this effort.
approach
researchers are employing molecular mechanics and electronic structure calculations to predict the optical and transport properties of molecules that could become the next generation of solar cell materials.
a) molecular mechanics calculations: some of the computers contributing to the clean energy project are carrying out molecular mechanics calculations of molecular crystals, thin films and molecular and polymer blends to study the packing arrangements and for predicting charge and excitation energy transport properties of the candidate materials. these calculations will be carried out using the charmm molecular mechanics package developed by the karplus group at harvard university.
b) electronic structure calculations: to obtain the relevant optical and electronic transport properties, some of the computers connected to the clean energy project will be computing calculations using wave function methods (such as hartree-fock or second-order perturbation theory) and density functional theory. these calculations will help researchers build a database of molecular properties that together with the results of the molecular mechanics calculations will help us identify potential candidate materials. the electronic structure calculations will be performed with the q-chem quantum chemistry code, developed by q-chem, inc."
abraço!
