Energy Mastercourse @ Telethrion

...For The English Translation Please Press Here Free and Real is hosting in the premise of the Telaithrion Project, in cooperation with SEYN (Sustainable Energy Youth Network) a ten day practical and theoretical workshop in Northern Euboea about: Low Impact Technologies, (DIY), Renewable Energy Recourses and intro to the Telaithrion Project The Workshop will Start on Friday 17 February and it will conclude on Sunday 26 February Deep into the waters of renewable sources of energy, DIY/DIT applications and low impact technologies, we will dive for this ten days extensive workshop with the valuable help of SEYN and Alexandros Filippidis. In this workshop we will construct together many different applications and we will deeply analyze in theory their possibilities. The seminar is aimed at those that wish to acquire knowledge both theoretical and practical, about renewable energy sources to meet workable alternatives to a personal and community level. Some of the subjects that we will be dealing with: Biodigester construction. A biodigester operates as a kind of mechanical “stomach”. Fed with organic material, which then decomposed, creating biogas and valuable fertilizer. Off grid system sizing and calculations. Through this workshop we calculate our energy needs and consumption and then design from scratch the desirable system. Our scope is to gain a complete knowledge on various system components like wind/hydro turbines, solar panels, batteries, inverters and energy systems on theory and practice. Building a solar charger for mobile devices and tools A very useful and portable device, a solar charger can give life to a large range of gadgets such as laptops, cell phones, digital cameras etc. Upcycling old speakers to a portable Bluetooth sound system. We all have a pair of old speakers from an old hi-fi. Here we will learn how to get them a new life and build a portable, off grid Bluetooth sound-system with low cost, ideal for events, parties, etc. Building a solar panel. In this case, we will learn how we connect simple solar cells to make a functional and low cost solar panel. Building a solar water heater. The solar heat can be used for heating domestic hot water (DHW) and also can be used for space heating by preheating the water. In both cases it takes advantage of the solar radiation and therefore the use of it is for free. Solar thermal systems can cover from 10% -60% the needs of a house of heating and hot water, giving a corresponding saving in current oil , LPG, … etc.The solar heating systems can function in combination with any other of heating system* oil boiler, wood, biomass, gas, heat pump, etc.), whether in an existing heating system or due to new facility. Solar cooker and solar dehydrator Here we will see how to build a solar oven, a simple construction that can cook any food or boil water by using only solar energy and without the need of electricity. The solar radiation penetrates the glass and it’s been converted into heat which get trapped in the interior of the box by continuously increasing the temperature .The idea of drying is very old. The sun helps us to get rid of the liquid and the humidity of the foods we want to preserve. The solar dehydrators Are made of two parts. At one part happens the “collection” of solar radiation which heats the air and the other part is the food which we want to dry. Solar air heater This construction will consist an autonomous solar air heater with an integrated solar panels. Every time there is sun, the radiation passes through the transparent cover and the special absorber heats the fresh air in the collector. The outside air has already been filtered before it enters your site. Pedal power and retrofitting an old washing machine And other types of kinetic energy. The basic idea is to use a bicycle e as an energy source , and...
