Energia solar o futuro energético do sul

Para Portugal o futuro energético passa muito simplesmente pela energia de uma célula fotovoltaica cujo principio é tão básico que deveria ser ensinado e experenciado em todas as escolas do ensico básico,  principio esse que deve ter sido descoberto por alguém que muito simplesmente fez aquecer ao sol dois velhos discos de vinil provocando o  aquecimento de um destes que eletrolisando um liquido à base de etileno, talvez alcool provocou através do seu aquecimento a "eletrólise" desse liquido que funciona como semicondutor no conjunto dos dois discos de vinil um mais aquecido do que outro.
Escrevo isto num telemóvel Samsung produzido na Coreia que funciona sobre o mesmo principio.
As lâmpadas led funcionam com uma potência de 3 a 5 w e ainda menos comparadas com as de filamento 10x mais potentes, e depois todos os computadores, telemóveis, leitores de mp3 e tudo o que precisa de uma pequena tensão continua e uma baixissima potencia como até os comandos de televisão funcionam com baterias de lithium, material abundante em Portugal, sendo as nossas reservas avaliadas como as 6as maiores do mundo e para mim talvez as primeiras do mundo...

START POINT OF THE UNIVERSE

Back to basis, I have no doubt that absolute darkness was the start point of light, and the Universe as we know it. What science has to find is time development. With C14 we can not say that Earth began 4000 million years ago. So we'll have to find out how to search. From the sun, the earth, the solar system, to the center of the Earth. To the center of the Earth, that would not give us with magmatic rocks, anything like 4000000000 years, what I read from dating with C14 was something like 60000 years. We can find a "Go between" scale linked to waves to date coal. But it is hard to believe in this gap above. On the other side there is the biology, the bacterias, unicellular cells and multicellular cells, but their dating is linked for sure with the Big Bang theory that it is right at the start, but we can not prove the exact start point on time and time developping. Due precisely for what we can prove or not with light. So light is a wave, no light should be no wave, so t...

To see or not to see

This is a blind date. People can no longer see absolutly nothing, as I do, besides perhaps on Youtube. Cinema on tv... Cannes was the meca of cinema, "La berlinale" showed movies from allover, worldcinema. Venice, I just do not comment. In the US as in europe in generall people are no longer gathering besides american apps. Content for television is now linked to "La HBO and Netflix". The rest is what I referred yesterday, the films of Edgar Pêra, Pedro Costa and first Miguel Gomes who are caracterizing this pitoresque landscape of the so called "tv reality", that I could not escape myself. In a way as I did 13 years ago, not in the mood for 1h30m long film in a daily basis, but short films are easy to watch, so that is what I'm trying to do daily. For cinema directors allover, people who are in the schools of cinema of not, people from around the globe, I would like to see 15m to 30m short film, on the internet, to aknowledge people, arts, politics, s...

Round commentary on present and future economical issues concerning Portugal and the EU

Unemployment rate in Portugal is good, but due to what I think is an excessive time people waste atending tv,  specially at lunch time, say 2h, I am a bit for emmigration in Portugal and in EU, it will allow concorrence on the labour market, higher levels of produtivity, that can perform a better economy in order not to continue to make debt, that has to be paid someday and keeps pushing inflation and  that can really ruin economy.  What do portuguese and worldwide economists think about a 15%  bank ratio between credits and deposits? I will not comment this latest gates linked somehow with irrealistic politicians, and personally what I think what has to be done with people who perform public jobs is to limit to 8 year the time they can remain in power. I just read the title of an opinion of mr. Francisco Louçã on expresso online, and he was bringing underlines the link between British airways and Iberia, do not people from London fly to Portugal? To Lisbon, to Oport...
