Venture capital firm Andreessen Horowitz just announced that it has closed its Fund IV. And it’s a massive $1.5 billion fund for all sorts of investments from seed rounds to late-stage rounds.

Previously, Andreessen Horowitz had raised $300 million in 2009 (Fund I), $650 million in 2010 (Fund II), $200 million in 2011 (Growth fund) and $1.5 billion in 2012 (Fund III).

“We’re going to keep doing the things that we’ve been doing,” partner and COO Scott Kupor told me in a phone interview. “We want to look at everything and be able to invest.”

Among the reasons cited as to why venture capital is an exciting space right now, mobile comes first. Kupor writes that billions of new people will get a smartphone in the coming years, which will greatly increase the Internet population.

At the same time, technology costs have gone down dramatically. For example, Andreessen Horowitz recently…

Grande successo l’ Arte Fiera  di  quest’anno con quasi  50000 visitatori  in aumento rispetto all’edizione passata.

In aumento anche il numero , 172, di gallerie presenti .

Interessanti le sezioni proposte, dall’Arte Moderna e contemporanea, alle “Nuove proposte”  con opere di artisti nati dopo il 1979 e quella di “Solo Show”  con stand monografici fino a quella della Fotografia  che vede la collaborazione con MIA, la fiera milanese specializzata in fotografia.

Come fotografia ho trovato particolarmente intrigante la produzione di Nino Migliori , della Galleria Duemila&Novecento  che rende, con maestria, frutta e verdura, notevoli  protagonisti  delle sue fotografie. Qui un’immagine  della serie “Il tempo rallentato” (2009, pure pigmented print on cotton paper.securedownload

Ho apprezzato in modo particolare l’allargamento dell’arco temporale nelle opere esposte nella sezione Arte Modera con l’ultima produzione dell’Ottocento, con gallerie che trattano quasi esclusiva mento questo periodo come la Parronchi di Firenze qui  un Lodovico Tommasi con caratteristico paesaggio toscana,

054 o la Bottegantica di Savona con alcuni bei Boldini, De Nittis, Mosè Bianchi

046o ancora la Enrico di Genova con questo  ritratto di Alice Regnault di Boldini,


accanto a quelle che trattano sia l’800 che il ‘900 come la Galleria Studio d’Arte dell’800/900 dove mi ha colpito questo Galileo Chini di atmosfera.


Nella sezione Arte Moderna il ‘900 e ancor più il secondo novecento fanno la…

You probably won’t be receiving a utility bill from Google anytime soon, but the search giant is slowly but surely morphing into a literal power broker. Yesterday (Sept. 17), for instance, Google announced that it would buy all the electricity generated by the 240-megawatt Happy Hereford wind farm to be built near Amarillo, Texas.

Google’s main goal is to make itself greener. Google Energy, the company’s power subsidiary, which has a US government license to buy and sell energy like any utility, will sell the electricity from Happy Hereford into the wholesale market in Oklahoma where one of Google’s massive data centers is located. The data center can’t take the power directly from Happy Hereford; it buys electricity from its local utility, which may buy it from the wholesale market. But by selling green power to the grid, Google gets to deduct emissions from its carbon footprint as if it…

There has been much talk of alternative fuels to keep our classics going as petrol becomes ever less attractive. But after all is said and done, more has been said than done.
Here is a brief summary of my experience and some hearsay from down the pub, it is quite possible I have made a mistake here or there so if you spot one do let me know.

Mostly Propane with a splash of Butane, stored as a liquid under a pressure of about 5 bar in steel cylinders. The fuel is turned into a gas and the pressure regulated in an evaporator that is heated by engine coolant. The simplest way of feeding the gas into the engine is by using a gas carburettor, but these are quite restrictive…
