What the “artificial leaf” needs:
- inexpensive materials (nickel and cobalt)
- water to be split into hydrogen and oxygen
How long does a single artificial leaf work?
- at least 45 hours with no drop in productivity (which is also 10 times higher than natural photosynthesis)
“Placed in a single gallon of water in a bright sunlight, the artifical leaf could produce enough electricity to supply a house in a developing country with electricity for a day“. Dr. Daniel Nocera presented his research at a meeting of the American Chemical Society. If this is all true, who will still need nuclear power ?!?

La Tommesani.it elettronica l’ha pensata bene e organizza un livestream di un suo contatore Geiger in quel di Bologna.
Un servizio utile, specie dopo aver letto qui che in Romagna si sono registrati picchi di 0.22 milliREM/ora, mentre la media naturale potrebbe essere intorno a 0.004 milliREM/ora (se calcolata dividendo i naturali 0,1 milliREM per 24 ore), ossia ci potrebbero essere picchi 55 volte superiori alla radioattivita’ fisiologica dell’ambiente.
Misurazioni piu’ estese e medie di valori invece che “picchi” spiegherebbero molto meglio la situazione, che comunque risulta normale.
NB: L’unita’ visualizza microsievert per ora (una media di 0.11/ora nel momento in cui scrivo il post). Per lavoratori con esposizione professionale a sorgenti radioattive l’unione Europea ha stabilito limiti massimi da 3 a 10 microSievert/ora – ossia al momento siamo 100 volte sotto i limiti.

I would really like to see how any other European country would manage the massive illegal immigration Italy is suffering at the moment.
Tunisia and Lybia, just to cite two countries, are shifting North towards Lampedusa to later reach continental Italy. Neither Germany, nor France or UK give a damn **** to what is going on in the southern shores of the continent.
If I were Italy’s government I would just fill hundreds of train wagons with these thousands of young and healthy immigrants and send them to France if they speak French, for example. Spain (or Morocco?) shot them before they could cross the border: admit at least Italy is acting much better.
I wonder what Italy earned from joining Europe:
- out of control gypsies thrown out of Romania
- tons of communitarian money to feed mafia and camorra
- European parliament seats for Italian parasitic politicians
- a strong currency that killed Italy export
- thousands of migrants bombed by France and UK fleeing to Italy
… and all this happened with one of the worst government Italy ever had – that’s exactly why Europe does not care about it.

It is not easy to organize a relaxing bike tour in Zurich, being the city all up and down. That’s why we transported our bikes uphill and we organized a short 15 kms tour on the up side of the “Zuri Golden Coast” – meeting a couple of forest creatures energized by these first Spring days. Give a look to these playful squirrels and to this nesting bird

Ma come e’ possibile che il vicepresidente del Cnr parli di catastrofi come “voce della bonta’ di Dio” in quanto ci ricordano che la nostra vera natura e’ lassu’ in cielo e non qui sulla Terra? Medioevo chiama Italia, e Italia rispose come sempre! Siete il Terzo Mondo d’Europa
Com’e’ possibile che Roberto De Mattei si chieda “perche’ Dio porta via anche gli innocenti?” e si auto risponda “mica gli possiamo chiedere interventi miracolosi a pioggia per salvare i singoli” ?
Speriamo che un miracolo del Gran Buon Dio personalmente disegnato per Roberto De Mattei lo rimuova dal Cnr, o magari lo porti lassu’ a dare un’occhiata al cielo, dove io credevo ci fossero galassie e materia oscura…
Firma la PETIZIONE ONLINE per far rimuovere questo talebano dalla vicepresidenza del Cnr (carica chiaramente incompatibile con tale personaggio) … nel caso il Buon Dio abbia altro da fare, diamogli una mano: firma anche tu.

Earth Hour is an initiative “to take a stand against climate change”. Earth Hour “has done a lot to raise awareness of sustainability issues”.
So, please, tell me now how turning off lights will save our planet from climate change. In comparison, organized jumping sessions to change our planet axis sounded more logic. And, yes, show me what you do to go “beyond the hour“, I am already thrilled…
Anyway, a banal excuse for a night out.

Although on media Fukushima is not a top news anymore, in the Pacific Ocean close to Fukushima radioactivity levels reached 1250 times the natural radiation. That means, half a liter of this contaminated water contains the maximum annual radiation dose we can absorb.
Good to know, iodine-131 has a half-life of eight days. On the bad side, cesium-137 measured in the same region is 80 times more the normal levels. Cesium-137 has an half life of 30 years.
There are no radioactivity data on larger and more distant Ocean areas, anyway, here are the FAO codes for the fishes caught in the Pacific Ocean:
61 Pacific, Northwest
67 Pacific, Northeast
71 Pacific, Western Central
77 Pacific, Eastern Central
81 Pacific, Southwest
87 Pacific, Southeast
88 Pacific, Antarctic

Wan*ing in a hurry at young ages may promote ejaculatio precox at older stages. This incredible discovery is made by the Italian andrologist Giuseppe La Pera. On 200 examined subjects, he realized that 90% of the patients suffering of ejaculatio precox were used to wan* in their bathroom, where they learned to couple anxiety status to orgasm.
Nowadays 30% of the world man population suffer of this dysfunction. Take care of your kids, parents: let them wan* in there bed without having stress
