A cooling system green and sustainable, which works through the heat rejected by a household refrigerator, seems a contradiction in terms, but it is not. Moreover the operation of this device, created by Fabio Molinas (Sardinia, 1988), pupil of the European Institute of Design, has been considered eco-efficient and innovative to the point that has been chosen by the Spanish jury as national winner of the 2013 edition International Design Competition James Dyson Award , organized by the eponymous foundation. we can say that is a smart refrigerator.
This means that Oltu, so called this unusual fridge, along with the other nine finalists among them eAlamp a self-adjusting lamp solar charging and Airoad, sustainable energy system from air bursts cars generate on the roads-will represent Spain in the next round of assessment of this prestigious event, which involves design and engineering students from 18 countries. This selection will include 50 projects, including James Dyson himself, British inventor and engineer, elected on November 7, the winner will get 40,000 pounds (47,000 euros, 35,000 to 12,000 for student and university) and two finalists, recognized with 2,000 pounds each.
Oltu , which in the Sardinian dialect means orchard, is a cooling system that uses the heat expelled by the fridge to keep containers cool placed above it, which is always kept wet by water tanks that the user must fill occasionally. "My main concern was to keep vegetables fresh, as fresh from the garden and also educate people to store food properly, preventing food waste due to inadequate preservation systems," explains Fabio Molinas, author of Oltu, which and in the past worked on design projects for food. br /> "The cold of the fridge is not the best for plants for different reasons: the onion releases gases and affects other foods, tomatoes become paste, citrus acid and cucumber, peach and banana lose most of their antioxidants, while out of the fridge this is increased to 20%. Hence the need to find the best way to recreate a small ecosystem capable of satisfying the needs of different groups of products, "said Molinas. Being smaller and spend half a standard refrigerator is not the only advantage of Oltu. Their real innovation lies in the use that is made of it. "I always say that my invention is like a parasite, which uses the heat and ambient heat to recreate some environments that favor the preservation of fruit and vegetables, which is not placed inside the fridge, so this is becomes smaller to contain only dairy products, meat, fish and frozen "continues Molinas, who has built a prototype intended for the consumption of a family of three people for two weeks.
They participate in the challenge engineering students from 18 different countries
Oltu not the only project focused on sustainable welfare of this young designer who has lived in Madrid for three years. Among those that can be seen on his website emphasizes Leather for vegetarian , leather substitute product, the manufacturing is very polluting, manufactured from cork powder reuse from the filing of the plugs.
