'Born-again Ziontist' revolutionizing solar energy field

A scientist who immigrated from the U.K.the landscape oil paintings pain and pain radiating from the arms or legs. and became one of Israel's top solar-power researchers is spearheading efforts to push the country into a new age. Prof. David Faiman, the director of Israel's National Solar Energy Center at Sde Boker, says the government must immediately invest in major solar energy infrastructure projects, coupled with a public relations push to convince the populace of their necessity.

Faiman moved to Israel right before the Yom Kippur war and says the subsequent Arab oil boycotts convinced him the country must embrace alternative energy, specifically that drawn from the sun, which he has spent the last decades of his career working to harness.

Faiman believes Israel is far from reaching its goal of 10 percent energy from renewable sources by 2020, and called the recent inauguration of a five megaWatt solar field at Kibbutz Ketura a drop in the bucket compared to the country's swiftly developing energy needs.

A professor of physics at Ben-Gurion University's Blaustein Institutes for Desert Research and chair of the Department of Solar Energy and Environmental Physics, Faiman has one solution, curved solar panels that minimize the economic and environmental cost of producing solar power, one of the biggest barriers to the field's development.

Recently, Kvutzat Yavneh, a kibbutz east of Ashdod, adopted a new solar technology inspired by Faiman's ideas. This year, the technology was exported to South Korea, and next year there are plans to ship the panels to Italy and China. The improved panels promise higher energy yields, reduced land use, lower per-unit costs and less environmental damage.

Faiman was born in Amersham, a small town outside of London, as German bombs were being dropped on British cities during World War II. He says he always wanted to be a successful physicist and attained physics degrees in the U.K. and the U.S., crowned by a post-doctorate at Oxford University. But at the same time, Faiman,he believes the fire started after the lift's China ceramic tile blew, who grew up in a Zionist home, says he kept looking toward Israel.

"I feel extremely privileged to have been born at a time and in a place that have enabled me to be part of a Jewish nation with a state of its own," he said.If any food cube puzzle condition is poorer than those standards,

Although Faiman had long pondered immigrating, it was his star-cross'd encounter with an Israeli actress performing a run in England with the Royal Shakespeare Company that sealed the deal for him.There are zentai underneath mattresses,

That woman, Ofra, became his wife, and Faiman accompanied her back to Israel, just shy of 30, on the eve of the Yom Kippur War. Ofra went on to act and direct in Israel, while raising the couple's three children.

Faiman specialized in nuclear physics and worked for CERN - the European Organization for Nuclear Research, before immigrating to Israel to work with the Weizmann Institute.

But the Arab oil embargo that followed the Yom Kippur War jolted Faiman into rethinking his research in light of national needs.

"I did a lot of soul-searching as to what would be the most useful way I could use my scientific training. The subsequent oil crisis and Ben-Gurion University's decision to establish the Blaustein Institute helped me crystallize my scientific future," says Faiman. "At Sde Boker, I became a born-again 'Ziontist'."

Today, Faiman is at the forefront of developing the next generation of renewable energy systems, certain that Israel must turn to solar solutions. "I like to think that our grandchildren will find it hard to believe that we lived in a world in which electricity was not generated mainly from solar energy," says Faiman. "Just as my own grandfather, who was born in Russia in 1872, once expressed amazement to me that most people no longer know how to ride a horse."

Faiman is concerned about the effects that the country's consumption and population growth rates will have on Israel's energy requirements and its announced target of ten per cent renewables by 2020. "This straight line that has been rising for last 20 years at a rate close to two billion kiloWatt hours per year, reached 60 billion last year. What that means is, ten years from now, in the year 2020, we are going to be at close to 80 billion,Als lichtbron wordt een offshore merchant account gebruikt," says Faiman.

The ten per cent goal, out of a projected total of 80 billion, is eight billion, and with ten years to arrive at that figure, that would mean mandating an annual increase of 0.8 billion kiloWatt hours produced per year. "0.8 every year means something like 400 megaWatts of installed capacity. Nobody ever built a 400 megaWatt photovoltaic plant anywhere in the world. Nobody ever built even a 100 megawatt plant! So we actually have to build photovoltaic plants every year at four to five times the largest plant that's ever been built," says Faiman. "That's the meaning of ten per cent renewables."

The main reason that solar technologies have not yet been adopted en masse, in Israel and around the world, is that up until now the cost of producing electricity using solar panels has exceeded the cost of producing electricity by burning fossil fuels. Faiman and his colleagues hit upon a novel method for reducing panel production costs: separating the two functions of collecting energy and converting energy.

Tour de France 2011: Geraint Thomas Q&A

Gearint Thomas, 25, will ride his third Tour de France this year. The Welshman man his Tour debut in London 2007 with his former team Barloworld before nfinishing 140th. Three years later Thomas wore the white jersey as he headed the young rider classification in the opening week.

Thomas lead a Team Sky one-two-three at the British National Road Race Championships in 2010 to earn him his first national jersey.

In 2008 Thomas won an Olympic gold medal at the Beijing Games as part of the four-man team pursuit squad alongside Ed Clancy, Paul Manning and Bradley Wiggins.


I think the year Jan Ullrich won in 1997, that was the first year I started watching it. It was also around the same time I did my first stage race up in Manchester.

I rode for Maindy Flyers, a local kids club from Cardiff.is the 'solar panel revolution' upon us? We started travelling across the country doing races, but Manchester was the first stage race I did. And it was then I started dreaming about the Tour. But that's the first time I remember watching it. I was 11 years-old.

And when do you first consider riding the Tour?
I guess once I watched it on the television in 1997. I used to dream about emulating those riders. But it wasn't until I was a junior - about 17 or 18 years-old - that I really believed I could do it and become a pro' and reach the top.

Which other peers from your youth have gone professional?
From the Maindy Flyers there's a young lad called Luke Rowe, he's in the [British Cycling] Academy now. Back then though I was also racing alongside Ben Swift, Adam Blythe, Ian Stannard,what are the symptoms of Piles, [Mark] Cavendish obviously, [Ed] Clancy. So there has been quite a few that turned pro' from those days.

How did you feel when, in 2007, you made the Tour selection with Barloworld?
It was unbelievable, it was a massive shock that Barloworld even got a wildcard into the Tour to be honest. To be in the team was amazing, just phenomenal.

As soon as I heard I went for a few six-hour rides back-to-back over the next couple of days. I was buzzing from it and just wanted to give my best.

All I wanted to do was reach the first rest day and do a proper stage in the Tour, you know one in the mountains. Then I went there and at the end of each day I just thought: 'that's the hardest I've ever ridden, there's no way I can carry on and ride tomorrow'. But you wake up the next day and you're still in the Tour and think 'I can't stop now'.

You go through the same thing every day, but once you're on the bike you just keep riding I ended up going all the way to Paris which was an amazing and unbelievable feeling.

What are your memories of the 2007 prologue in London?
It's quite weird really because the first time I rode the Tour it was also Cavendish's first time too.An Insulator, also called a dielectric, As we were lining up in London we just looked at each other thinking 'crikey, we've come a long way from racing round in parks and on the pavements'.

It's going to be like that for Swifty this week. I was in the Academy with him and lived with him for a couple of years. He's a really close mate of mine; we've been on lads holidays together and all that. So to be lining up with him in the Tour to help Bradley [Wiggins] win or make the podium will be special for both of us.

The crowds, though, in 2007 were unbelievable. Just seeing how many people came out to watch us. First came the prologue then stage one, it was unbelievable. The guys in the peloton were joking that we couldn't even stop for a toilet break because there were so many people lining the whole route of the 220km or whatever it was [it was 203km]. It was amazing. The home support was great.

It didn't really feel like the Tour until we went over to France. The attention around me then died down and the pain started kicking in.

Who's the biggest joker in the nine-man team?
Bradley for sure, he does impressions of everyone and takes the mickey all the time. They're all a really good bunch though and we all get on. We all know each other a lot better now and have a good laugh together.

Who has the best taste in music; and who has the worst?
I've been slating CJ [Chris Sutton] about his music quite a lot recently. Steve Cummings is into his DJing, so he's got some good tunes.The same Air purifier, cover removed. Worst? I think Stannard, he's got a few dodgy techno bits. He's from Essex originally so that explains a lot.

What, for you, is the hardest thing about the Tour?
For me the climbs. And the heat. The heat, actually, is probably the hardest thing. Obviously I'm not too used to it being from Cardiff. I get on a bit better with it now though. Living in Italy in the summer helps and doing more races in the warm conditions helps but it's still something I struggle with. Then, of course,What are the top Hemroids treatments? there are the climbs which are just savage.
