Nanotechnology can improve the solar water heating up to five times
Research conducted by scientists at the University of Rio de Janeiro (UFRJ), has enabled the development of nanotechnology from a new solar heating system allows rise the water temperature up to five times. Reportedly, the project has emerged from one of the enterprises of the business incubator of the URFJ.
Luiz Carlos de Lima and Marta de Moraes Well, both doctoral degrees in Metallurgical and Materials Engineering, began his research at the Laboratory of Thin Films of the university in 2004. That was the origin of Nano Select, the first company in the country that developed through nanotechnology selective surfaces for solar collectors, with high capacity to absorb heat.
According to Lima, the new technology, and heat the water five times more than ordinary solar heaters, is able to retain up to 98% of heat from solar radiation.
In concrete terms, the water can reach 300 º. “With that level of warming is possible, for example, the use of water in vapor form, allowing you to use turbines to generate electricity more efficiently,” said the investigator.
The surfaces created by Nano Select have been developed from film-coated aluminum oxide thin layers of metal and secured for use in solar collectors to produce heat and electricity through photovoltaic cells.
The company has won the award for Technological Innovation awarded by the FINEP, the Brazilian federal agency for financing science and technology studies. In addition, funding has been granted funds for micro enterprises and small innovative companies. According to Lima, thanks to these resources, new technology could enter the market on an industrial scale in the first half of 2011.
