What I see in Italy and also in Germany is a shift in paradigm. We go from a centralized electricity production to a distributed electricity production, following what happened in computers, from centralized processing to distributed processing. Of course this shift has many problems, which can be overcome using new tools, like "smart grids" and energy storage. They are widely discussed in the pages of the magazine "L'energia elettrica", published by the Italian Electrotechnical Association, of which, as I said, I am a member. Its seems to me that Italy is again leading the field of new electricity production methods, as in the first decades of the XX century, following the ideas of Galileo Ferraris.

ITER will not produce any electricity. It will only consume it, and of course it is based in France with its 54 fission reactors.

Solar energy has not the problems of spent fuel elements to be stored safely,as demonstrated in Fukushima. There is no agreement in Italy, but also in USA, for a storage of radioactive materials. France has chosen a location and is going to drill a deep well and a horizontal tunnel, but such a decision would start a revolution here in Italy. Fusion power is still a dream.

I am not proposing to eliminate power plants, just not to build new ones when unneeded. Just to give a few figures, electricity from renewable sources in Italy has reached 29.52% in 2013, including hydroelectricity. Photovoltaic, wind and geothermic account for 13.14%, Thermoelectricity is down to 57.7%. Trends are: hydroelectricity +21%, photovoltaic +16.4%, wind +22.4%, geothermic +5%. Thermoelectricity -18.8%. Those are official figures from TERNA. It is clear that every country must provide to its needs and there is not a common solution. But Italy has a lot of Sun and is going to use it.

Any new building should be self-sufficient by 2020, according to the European Community. No need for big power plants, and ENEL in Italy is shutting down many older thermal plants.

All CERN BOINC projects (Test4Theory@home, ATLAS@home and LHC@home), are to be united in a new vLHC@home project. The first 2 need Virtual Box, the third not so far, but it will need it in the future. I am running T4T and LHC@home, which studies the particles' orbits. I haven't been able so far to run ATLAS@home since it needs a 64-bit Virtual Box, while mine is 32-bit on my 32-bit Linux.

I still think we should use a very big fusion reactor at a safe distance, the Sun. Germany and Italy are using more and more photovoltaic energy, and there are also thermal plants as sponsored by Carlo Rubbia. In my small hometown there is a new building which gets electricity and heat from renewable sources, without impacting the environment. Electrical energy production should follow the some route of computing, going from centralized to distributed structure. Of course this needs to have "smart grids" and energy storage to give electricity also at night. I know that Italy's ENEL is working in this direction, as I receive the magazine "Energia elettrica" edited by the Italian Electrotechnical Association, founded by Galileo Ferraris, of which I am a member.

Oggi Nibali e' arrivato terzo a Arenberg, dando due minuti e mezzo di distacco ad Alberto Contador, dopo una gara drammatica sotto la pioggia e sul pave' della Parigi Rouubaix, che ha fatto numerose vittime tra cui Christopher Froome, caduto oggi due volte e ritirato, dopo essere caduto gia' ieri. Anche Mark Cavendish era gia' caduto durante la prima tappa in Inghilterra. Ma cio' che mi ha colpito di piu' in questa tappa partita da Ypres in Belgio sono gli enormi cimiteri militari della Prima Guerra mondiale, che ospitano centinaia di migliaia di caduti francesi, inglesi e canadesi. Domenica scorsa Riccardo Muti ha diretto il Requiem di Verdi nel cimitero di Redipuglia, che ospita centomila caduti italiani, alla presenza del Presidente Napolitano e dei Presidenti di Slovenia, Croazia e Austria, tutti Paesi nemici nella Prima Guerra mondiale, in quanto facenti parte dell'Impero Austriaco.

All good, but any fusion machine produces only high energy neutrons, not electricity. Neutrons are deadly beasts which destroy any metal in matter of hours (I've used them in my youth on a project for IAEA). So you must substitute the "first wall" in a short period of time but of course it is radioactive,and you must use machinery.The engineering problems of fusion reactors are huge, much more than any plasma physics problem. Enrico Fermi was able to produce some electricity from his "atomic pile" in a matter of days. So far no fusion experiment has produces a single watt of electricity.

Ok I think I know which reactor type your talking about . America probably pulling out mite have more to do with pride ? C.E.R.N is in France now this ? and then there is the American version with Lazers (which I think is a dud) and the money poored into that ? Deos anyone know if the Yanks are going to put the money into some other project ? or general coffers of the gov

There is ALCATOR at MIT, designed by Bruno Coppi. It costs much less than ITER. ALCATOR stands for ALto CAmpu TORus.A European version called IGNITOR (Italy and Russia) should be built at the Igor Kurchatov Institute in Moscow. Cost should be about 250 million dollars.

ITER was to cost 5 billion euro in 2006. It has already cost 15 billion euro in 2010 and is going to cost even more. Its start up was to be in 2016, now it is foreseen in 2026.But it is just a proof of concept plant, not even a demonstration plant, which means it won't produce any electricity, only 14 MeV neutrons. Then you must use them to heat some water, produce vapor which powers the turbines and the generators. There must be a simpler way to heat water.

ITER is both beyond schedule and beyond budget. I think nobody has the courage to say stop, it is too big to fail. The US decision is right.

The Cebit2 results are much in doubt today.We are still waiting for the Planck results, to be announced in October. My friend Roberto Battiston, one of the proposers of AMS-2 experiment on the ISS, has promised me to give a summary of the Planck results on his blog in "Le Scienze" online magazine. But since he has been nominated as president of the Italian Space Agency he must have his hands full now.

Ypres. That was where chlorine gas was used, as counseled by Fritz Haber, a Nobel prize winner. The story is told by Kurt Mendelssohn, a German physicist, in his book "Rise and fall of German science". When the German General Staff understood that the Blitzkrieg had failed, they asked the two top German scientists, Walter Nernst and Fritz Haber, for help. Nernst, a Prussian, advised the use of N2O, a gas used for anesthesia, while Fritz Haber advised chlorine gas. He was accepted. His wife, Frau Professor Haber, asked him not to put science in the support of war. He did not heed, and she killed herself with her husband's pistol. But Haber was a good German and went to the front. When Hitler came to power, Haber, as a Jew, had to flee to England and was welcomed by the English scientists.
