In a recent interview, Carlo Rubbia (Nobel Prize for physics) (as Scajola) said
"The oil and other fossil fuels are being exhaustion, but uranium is destined to run out within 35-40 years. We can not therefore continue to develop energy plans on the basis of incorrect predictions that might lead us astray. We must develop the most important energy source that nature always puts at our disposal, without limitation, at no cost: namely the sun every day illuminates and warms the earth. "
"When was the last reactor built in America? In 1979, thirty years ago! How important is the nuclear energy production in French? About 20 per cent. But the high cost of their 59 reactors have been supported by the fact State to maintain the nuclear arsenal. Let us remember that to build a nuclear plant requires 8-10 years of work that the proposed technology is based on a fuel, uranium in fact, of limited duration. And still, all over the world, waste problem. "
" There is no nuclear power safe. Or low-waste production. There is a probability, that every one hundred years, a step Nuclear power is possible, and this obviously increases with the number of power plants. "
" Coal is the dirtiest source of energy, most dangerous to the health of humanity. But it does not solve the problem by hiding carbon dioxide underground. In reality no one is saying how long it should remain, yet the CO2 lasts up to 30,000 years, compared with 22 000 of plutonium. No, the return to coal would be dramatic, disastrous. "
"There is a plant for the production of solar energy, built in the Nevada desert on English project. Costs 200 million dollars, produces 64 megawatts and to realize it takes only 18 months. With 20 such plants, it produces a a third of one gigawatt nuclear power plant. And the costs, which is still high, can be reduced considerably when they are manufactured in large quantities. Suffice it to say that a hypothetical square mirrors along 200 km on each side, could produce all the needed energy to the entire planet. And an area of \u200b\u200bthis size is equivalent to just 0.1 per cent of the desert areas of the so-called sun-belt. To supply electricity to one third of Italy, an area equivalent to 15 nuclear plants by a gigawatt, a single ring as big as the solar connection of Rome. "
"The new solar thermodynamic plants capture the energy and concentration to the hold in special containers until needed. Then, through a heat exchanger, to produce the steam that drives turbines. Neither more nor less than a dam, hydroelectric plants, water stops and releases it at the appropriate time to supply power. "
If it is so simple, why did not you?
"The sun is not subject to monopolies. It does not pay the bill. I believe this is a great opportunity for our country if we do we will do so very soon the Americans, as happened for the rest of the computer twenty years ago. " (March 30, 2008) Taken from the blog of Daniel Luttazzi.Può be an answer to those who ask if the problems concerning energy ............. CF
