Abstract: Historically, man has used energy sources at its disposal to do a job or to get heat. First his own physical strength or domestic animals, then the energy of wind and water and later would come the exploitation of fossil fuels, such as coal, natural gas, oil and nuclear energy. The availability of energy has been essential for humanity.
However, transportation and consumption of conventional energy is the origin of the major environmental problems afflicting our planet. Against this background, greater energy efficiency and increased use of renewable energy appear as part of the solution. All nonpolluting renewable energy sources except tidal and geothermal come ultimately from the sun. Wind energy, for example is caused by atmospheric pressure differentials caused by the sun's energy. This also causes the evaporation of water that then precipitates to form the rivers to obtain the hydropower energy. The sun also feed seaweeds and plants through the process of photosynthesis, for subsequent obtain organic matter or biomass. Finally, the solar energy uses the sun's rays to produce energy.
This is the reason to investigate and propose a system of clean and renewable energy to produce electricity and heat for an individual family house. It seeks to harness the sun's energy, renewable energy source currently not well developed in the world, but with recent advances in this field can be very efficient and cost effective.
The system proposed in this research project is composed of four well-differentiated parts:
1. Solar Collector
2. Energy Transport
3. Energy Storage
4. Energy Conversion
The solar (light) collector is an idea suggested by the Czech company Alumistr s.r.o. Collected energy is transported (as light) in optical fibers to the storage system, which is a chemical storage system provided by ClimateWell®, which allows the injection and extraction of heat at high temperature. Stored energy for
can be used directly for heating or converted to electric power by a Stirling engine.
The idea that this system should be used as the only source of energy for single-family houses. It is clear that the project is at the beginning of a long road before it is ready for the market.
