Resumo
O grande problema que a sociedade moderna deverá equacionar, sem dúvida, é a questão do abastecimento energético. A questão do crescimento e desenvolvimento econômico da humanidade passa, necessariamente, pelo desafio prático e material de buscar criar fontes energéticas alternativas que possam garantir a existência da indústria, nossos meios de transporte, a vida urbana e até mesmo a agricultura. Durante anos, a humanidade conseguiu sobreviver com fontes energéticas com base no trabalho braçal e de animais. A criação de fontes de energia inanimadas, como rodas hidráulicas e moinhos de vento, significaram um importante aumento na produtividade. O sol pode ser a solução para a questão do abastecimento energético no futuro. Estudos revelam que somente este ano, o sol lançará sobre o globo terrestre, 4.000 vezes mais energia que consumiremos. O presente estudo tem como objetivo analisar propostas, e fazer um estudo da viabilidade econômica de alguns sistemas para o aproveitamento desta fonte de energia limpa, inesgotável e gratuita, em se tratando de aquecimento de água para fins domésticos, principalmente como forma alternativa de propiciar às pessoas mais afastadas dos centros economicamente desenvolvidos, uma melhor qualidade de vida e fazer uma comparação com os sistemas tradicionais de aquecimento de água. Considerando que o homem do campo, por questões técnicas, geográficas e econômicas, foi ao longo do tempo sendo privado de alguns benefícios que são comuns nas cidades, mas não tão comuns a eles, e que estas privações têm impacto direto em sua qualidade de vida e na produtividade, se torna importante encontrar alternativas simples de geração de energia que possa ser difundida de forma a propiciar que cada cidadão construa de forma barata, através de materiais reciclados, utilizando elementos que lhe são...
The biggest problem that society should solve, unquestionably, is the matter of energetic supply. The question of economic and development growth of mankind go necessarily through practical and material challenge of trying to create alternative energetic sources, which may guarantee the industry existence, our means of transportation, the urban life and even the agriculture. For many years the mankind has managed to survive with energy sources based on country work and on animal traction. The creation of inanimate energy, such as hydraulic wheels and windmills, meant an important increase in the productivity. The sun may be the solution for the matter of energetic supply in the future. Studies show that only this year, the sun will throw out 4,000 times more energy on the Earth that we will consume. This study aims to analyze proposals and also to study economic viability of some systems in order to make the most of this clean, inexhaustible and free energy. By dealing with water heating for household use, mainly, as an alternative way to help people living far from economically well-developed centers, a better life quality and also to compare the existing and traditional water heating system. Whereas the country man, for technical, geographic and economic reasons, has been foregone from some benefits which are common in the city, but not so common to them, and these privations have direct impact on their life quality and also on their productivity, this becomes important to find simple alternatives of generating energy that can be spread in order to help each citizen build cheaply through recycled material, by using familiar elements, instruments that can collect and transform the most plentiful energy on the Earth: the solar energy. The present study analyzes the economic viability of the implantacion of alternative systems of heating of water, through the solar energy, mainly...
