Willis quando abitavo a Salvador de Bahia il teleriscaldamento funzionava con una centrale nucleare a fusione fredda, ancora qualche mese e la verità verrà a galla, tranquillo...
probabilmente è come per il trottolone egizio, o la supercanna magnetica da usare mentre si guida, in ogni caso il black out sta arrivando?

I believe that in an enlightened society with unlimited energy to fuel it, the free market will provide unlimited innovation and opportunity for growth. Unfortunately we live in a world and society that is neither enlightened, nor do we have a cheap source of unlimited energy. What we have is an expendable source of cheap energy that has provided our race with an opportunity to grow and develop at an unrelenting pace. Take it from someone who once was the number 1 chear leader for the free-market and it's benificent role in modern society, it is blind optimism to believe this trend can continue. I say this simply because there is not a single renewable or alternative energy source that can replace oil. In fact, there is not a single renewable or alternative energy source that does not either rely on an industry that is subsidized by a cheap energy source (oil), or that does not result in a net loss of energy. Oil is a great thing, it's allowed our race to expand well beyond the solar limit's which constricted our growth prior to it's discovery. But with no alternative that is even remotely promising, I believe we're in for some extremely interesting times. My one personal hope is that we can discover how to sustain nuclear fusion and have it produce more energy than it and the supporting industries required to sustain it consume. THAT is our one hope.
Nonsense. Whilst nuclulear fusion would be nice, there is another alternative that we could theoretically move to should it come to that. It is in fact the logical thing to do.
Currently, we have a super source of energy. Oil is great. I mean, we can synthesise plenty of things like it, but that is the point. We have to synthesise them. Oil is just laying around. How awesome. Anyhow, oil also has very little to no significant role in the ecosystems of the earth, being buried far below the surface. This means we can burn it all without royally screwing entire ecosystems. Still, we are lost without it.
First lets look at alternative energy. 'Green' energy, as they call it, doesn't remain green if it is demanded in the quantities that oil is demanded in. If all of the worlds energy demands were placed upon nuclear energy, we would be out of uranium in 50 years. If it was placed of wind energy, you will find horrendous disturbances to global and regional wind currents, upon which millions of ecosystems are built around. If it was placed on solar energy, say by covering the ocean or sahara desert with panels, you would obviously destroy the local environment, but you would also rob the atmosphere of heat, lowering global temperature, and creating unusual convection currents. Geothermal energy demanded in global quantities cools the interior of the earth- who knows what that could lead to.
The problem in each instance is the same, destroying the environment upon which we depend. When you try to source such immense and vast quantities of energy from an ecosystem, you cannot avoid harming it (or at least altering it drastically). So what is the solution? Don't get the energy from earth. We can be as regardless as we please in the uninhabited sterile expanses of space and deserted celestial bodies. Consider this. What if we were to construct an orbital solar energy power station. Work out how much minimum energy we require, convert that into solar panel area, then put them into space. There are obvious hurdles and expenses, but they would easily pay for themseves.
Anyhow, ideal pipe reams aside, what I meant when I said everything would be fine, in reference to the hand of the market, is that market demand for energy will automatically co-ordinate with supply and cosequently price to restrict actual strain on resources to a perfect optimum. As there are less ridiculously cheap forms of energy available, supply will constrict, whilst demand remains more or less stable, pushing the price upward, and thus lowering consumption. It's all about opportunity cost. Right now driving to work costs less than a can of coke. After the dusk of oil driving to work will still be possible, but it might cost you more than a carton of coke cans.
