| A mina de água - The water's cave |
Mostrei uns vídeos de uns brasileiros a explicar como se fazia o sistema ao meu pai e a sua cabeça começou logo a magicar.
Nunca conseguimos colocar o sistema a funcionar. Os tubos que passam por dentro das garrafas tinham sempre algum ar (o que não pode ser) e também desconfio que o declive não fosse suficiente para todo o sistema.
Entretanto o meu pai comprou uns sacos pretos com uma pequena mangueira que acabei por utilizar daí em diante. O sistema é bem mais simples mas que me obriga a acocorar para lavar a cabeça.
Construção
Nessa altura só ia ao Montijo aos domingos e o meu pai avançou e muito com o projecto. Recolheu garrafas junto de cafés e restaurantes, comprou, pintou e ligou os tubos. A água é mantida num barril com duas entradas e duas saídas. A altura de cada buraco é muito importante pois a água quente vem para cima e a fria fica em baixo. Assim o furo mais acima é o de entrada da água fria da mina e tem um tubo para a enviar para baixo e um fecho com um braço flutuante para parar quando cheio. O a seguir é o da entrada da água quente que vem das garrafas. Dos dois em baixo, um é donde sai a água fria para as garrafas e o outro é a saída de água quente para o duche mas necessita de um tubo (também com um flutuante para enviar a água quente que está à superfície). As garrafas são encaixadas umas nas outras com o fundo cortado para fazer efeito estufa e lá dentro levam pedaços de alumínio das embalagens tetra-pak que potenciam o aquecimento.
Utilizaçao
Infelizmente nunca foi utilizado :/
Melhorias
Ainda não coloquei esta ideia de parte. O barril te os furos feitos e as garrafas com os tubos estão guardadas. Na altura ainda não perceba bem como "ferrar" um tubo. Isto é, tirar-lhe o ar. Coisa que o meu irmão já faz há muitos anos em aquários e me ensinou (e foi bem útil num projecto à frente). Também acho que alongando os tubos para permitirem que as garrafas fiquem mais abaixo (até mesmo ao nível do duche) ajude. De qualquer forma, agora não é uma prioridade.
Custo
Cerca de 150€ em tubos, conectores e cola.

It was summer (in 2015) and here when the sun disappears, it cools down. The main source of water in the land is a kind of water cave. A structured excavation with big stones made a few decades ago (I still have to know how they did it) where springs will end. Conveniently, it is at a point with a reasonable height. The shower would be on the lower terrace, and the heater would have to stay along the way to heat the water.
I showed some videos of Brazilians explaining how the system was made to my father and his mind started do ruminate.
We never managed to get the system to work. The tubes that pass through the bottles always had some air (which cannot be) and I also suspect that the slope was not enough for the whole system.
Meanwhile my father bought some black bags with a small hose that I ended up using thereafter. The system is much simpler but I have to squat to wash my head.
Making
At that time I was going to Montijo only on Sundays, and my father went on and much with the project. He collected bottles from cafes and restaurants, bought, painted, and linked the pipes. The water is kept in a drum with two inlets and two outlets. The height of each hole is very important because the hot water comes up and the cold stays down. So the topmost hole is the inlet of the cave's cold water and has a pipe to send it down and a floating arm to close it when full. The next is the one of the hot water coming from the bottles. Of the two below, one is where cold water flows out to the bottles and the other is the hot water outlet to the shower but needs a pipe (also with a floater to send the hot water that is on the surface). The bottles are attatched in each other with the bottom cut to make a greenhouse effect and inside them are pieces of aluminum from the tetra-pak packages that increase the heating.
Use
Unfortunately it was never used :/
Improvements
I haven't put this idea aside yet. The drum has the holes and the bottles with the tubes are kept. At the time I still didn't understand how to prime a tube. That is, take the air out of it. This is something that my brother has already done in aquariums for many years and he taught me (and it was very useful in a project ahead). I also think that by stretching the tubes to allow the bottles to stay lower (even at the shower level) might help. Anyway, it's not a priority now.
Cost
About 150 € in tubes, connectors and glue.
