reportAfter 5 days in Switzerland we headed towards the North.800 kilometres separated us from our destiny, Berlin.We spent one day on the never-ending German freeways, and after many hours, service stations, fast meals and more kilometres, we finally arrived at the capital. Awaiting us was the restored communications tower of the old Berlin-East.
When you have spent some days driving around Berlin, covering many kilometres along its avenues and streets you realize how large it is. For example, to go from our campsite, in the west of the city, to the centre, we crossed about 20 kilometres. That explains the impeccable network of public transport that they have; the innumerable tramlines, underground, train and buses arrive to all the corners of Berlin. What attracted our attention was the lack of barriers and “security” in order to control the sale of tickets. We assume that they consider that it really is a “public service” and the action of paying for the ticket is the contribution of each one to maintain it. A good public transport means less traffic and therefore less pollution (acoustic and of the atmosphere); something that unfortunately is not applied too much in our lands, where often the lack of efficient public transport and/or the prices force people to use the car.
The first impression of Berlin was strange. It seems strange that an old city, or historical constructions or monuments do not exist. In terms of the city the mark left by the wars of its recent history lasts. On the other hand World War II devastated the entire city, its churches, monuments, and their old districts. And on the other hand, the “cold war” and its famous Wall divided it into two parts with different systems to it.
La verdad es que estuvimos muy a gustito allí, pero el deber
nos reclamaba y pronto pusimos rumbo a nuestro siguiente destino...Dinamarca. Ekogaia projectTo continue with what we began in Switzerland, in Berlin we used our time in completing the infrastructure necessary to work from our caravan, as well as in visiting those places of which we had reference (and some more that we were discovering in Berlin). As far as the infrastructure, we had no problem locating the material
as well as the necessary advises in a type of supermarket of caravanning
equipment. There we could confirm our idea that in Germany they
are more familiar with renewable energy. On the other hand, referring exactly to the Ekogaia project, we
got to know closely diverse experiences around renewable energy:
two powerboats comprised of the network of distributors of biodiesel;
the UFOP, an organ of management created by associations of farmers
and producers of rapeseed; and UFA FABRIK, an echo-district that
has been self-sufficient for years.
According to our data, in all Germany there is a network of more than 1600 powerboats that sell biodiesel. So that it was not difficult to locate these powerboats in Berlin. Therefore, we decided to visit a couple of them and to fill the tank with their biodiesel that was somewhat thicker than ours to be able to verify its yield. On seeing the wide use of “ colza” in Germany, or to elaborate biodiesel for its nourishing use, we remembered the bad image that this oil had for us, in spite of it being verified as one of the healthier ones. We wish to emphasize the fact that biodiesel turned out to be quite
a lot cheaper than the mineral diesel in all the powerboats that
we saw. Thus, while the mineral cost 89 cent/euro, we got to find
biodiesel for 76 cents. That is the reason why biodiesel is widely
consumed in Germany, according to our contact in the UFOP. On the other hand we noticed the great difference between the great
multinational companies and the small chains. When driving around
the freeways whose petrol stations were of great oil (Shell, BP
e.t.c.) no biodiesel was available. Absolutely the opposite of
what we ran into once in the city, where it was in the powerboats
of the small chains.
During the summer of 1979 a hundred people took over land and buildings that had been abandoned in an old factory of cinema, with the intention of creating a place for trying out new forms of life, integrating art, work and daily life. While they were renovating the place it soon turned into an echo-district within West Berlin and was a pioneer in rubbish separation and recycling, for example. With this philosophy, today we can find there houses, restaurant-cafeterias, a cultural centre, (concerts, theatre, and diverse courses and workshops), a farm, the store with its own ecological products, space for children and all in green surroundings. A variety of interesting experiences: - Earth roofs. By means of a roof made of a plaque stuffed with recycled paper, where a stone layer is placed, with another layer of earth where the grass is allowed to grow and that replaces the roofing tile, they have obtained a system that adapts to the effects of the climate on the tiled roof and keeps the temperature of the houses warm. - Solar panels. From the entrance of this special centre, different
facilities from solar panels could be seen, as much thermal as
photovoltaic. They commented that they had installed different
types from panels (with polycrystalline, monocrystallines and
amorphous cells) to be able to make a comparative contrast of
the yield of the different types. Also they experiment with different
systems from solar pursuit for the solar panels. One of them is
controlled by a computer to follow the solar trajectory. It’s
more expensive but more efficient than the others; although it
was the other ones those that attracted our attention; the first
used two small panels facing itself, and the last one consisted
of a simple hydraulic system, where the movement caused by the
pressure of the heat causes the plaque to face the sun. - Aeolic generator. As the process to make the blades of the Aeolic generators was very expensive for them, they decided to try something new and thus they were able to patent their own system, which at the moment is being tested and is giving very satisfactory results. Having obtained higher yields than some similar generators as we could verify. Its plan is to put it on the market if they obtain a good product. - Filtration and reusability of the water. In order to reuse the rainwater, they use a system in which, once gathered the rain waters are passed through a filter made up of a land with vegetation that for its growth absorbs chemical substances, partly cleaning the water, that will still have to pass a last filter in the form of stone layers. Once clean, as it is not drinkable this water will be used for various purposes (watering and Toilets). This way a lot of water and money is saved.
www.ufop.de UFOP is a managing organisation created by different associations from farmers and agricultural producers, that work in the following areas: such as the element of political pressure in German and international institutions, promoting investigation and innovation for the production improvement, creating new forms of operation, and promoting the use of oil and native protein plantations. Besides speaking to us about
the UFOP, Norbert, our contact there, he spoke to us extensively
about biodiesel. About the cultivation and elaboration of rapeseed
to produce biodiesel, the laws that govern their commercialisation,
as well as of the awareness of the society towards renewable energy.s. There they confirmed the importance of the visit to the Biodiesel plant of Leer, also in Germany, where all the process can be followed, from the harvesting of the rape plant, the pressing of the seeds and the elaboration and distribution of biodiesel. We’ll visit it later.
In addition to biodiesel it is to emphasize the abundant presence of the renewable energies, as much Aeolic as Solar, in all Germany including Berlin. In the capital city there is a large amount of panels: as much on the roofs of public buildings as on the private ones, or on the parking meters. The use of the solar panels power contrasts with the idea that we have about Germany as a cold land, demonstrating its capacity and potential. But the Aeolic energy is not left behind, as we could verify during the long trip to Berlin. Along the sides of the motorways (all of which are free) were innumerable dispersed groups of windmills, perfectly integrated in the surroundings. Finally we do not want to forget to mention the infrastructure
that they have regarding the rubbish collection and its selection.
In the same way that they prioritise the returnable and re-usable
package, (the bottles, the bags of the purchase.) you can find
everywhere (in the Underground, airport or in the streets) containers
of all types and sizes, for the selective rubbish collection.
It would be good for seeing all these advances in our countries.. |
