Desertec projects moves beyond planning stage

European and North African governments have ushered in a new implementation phase of an ambitious green energy project called Desertec. It hopes to bring renewable energy from Africa to Europe. (from dw.de)

A number of governments in Europe and North Africa have redoubled their efforts to finally get an ambitious green energy project off the ground, Germany’s daily “Süddeutsche Zeitung” reported on Wednesday.

France and Germany, whose Desertec Industry Initiative aims to source future European energy supplies from solar and wind power produced in the deserts of North Africa and the Middle East, have been important financial supporters in the initial phase.

The two nations have been joined by Spain, Italy and Morocco for intensive talks on letting the project finally take shape. According to newspaper reports, negotiations are under way on building a 600-million-euro ($778 million) solar power station in Morocco which is to transport energy to the European mainland.

Pilot project

The “Süddeutsche Zeitung” said a corresponding declaration of intent would be signed as early as November this year. It added that a government-level multinational agreement would be inked in the first half of 2013, quoting Morocco’s Industry Minister, Abdelkader Amara.

Desertec Chief Paul van Son stated the solar power plant in question would be built between 2014 and 2016 and would eventually have a capacity of 150 Megawatts.

The project will be co-financed by industry, national governments and international energy organizations. Nations other than those already involved in the scheme would be welcome to join in the process, the industry initiative said.

Kanayo F. Nwanze Change Africa from Within

Kanayo F. Nwanze is President of the International Fund for Agricultural Development (IFAD), an international financial institution and a specialized agency of the United Nations. A severe food crisis currently threatens southern Sudan. In East Africa, where millions of people already are dependent on food aid, a sharp rise in the cost of staple crops looms.
(Interview 29.08.2010 from project-syndicate.org)

These are just the latest sources of concern in a turbulent period that began two years ago when food shortages hit many countries in Africa and Asia due to a worldwide spike in prices. Higher food prices meant that poor people, already struggling to meet basic human needs, were pushed deeper into poverty. On its heels came the global financial crisis, which also hit the poorest the hardest.

Agriculture is the main employer, job creator, and export in most developing countries. Historically, agriculture has driven economic performance in many countries, generating growth that has been shown to be at least twice as effective in reducing poverty as growth in other sectors. Investment in agricultural and rural development is therefore vital to food security and sustainable economic development.

Indeed, the vast majority of today’s developed countries grew from strong agricultural foundations, where surplus production generated wealth and prosperity. This is what is happening today in Vietnam, and it is the path that China and India took on their way to becoming engines of economic growth.

Poverty is predominantly rural. Globally, three-quarters of people living in extreme poverty are in rural areas and depend on agriculture and related activities for their livelihoods. About 380 million women, children, and men in sub-Saharan Africa live on less than $1.25 a day.

Many are malnourished or hungry. But, with some 80 million small farms in sub-Saharan Africa producing 80% of agricultural goods, smallholder farmers have a key role to play in resolving the financial and food crises and unleashing Africa’s potential to feed itself.

In order to lift people out of poverty and ensure food security, a sustained effort is needed to develop Africa’s agriculture and the associated infrastructure – notably roads, telecommunication, and energy – needed to unleash agricultural potential. Strengthening agriculture is one of the best investments any African country can make.

Members of the African Union recognized this in 2003 in Maputo, Mozambique, pledging to increase spending on agriculture to at least 10% of national budgets. Although eight countries have met or surpassed that target, the continent as a whole has not.

But reaching this target is not enough. Governments must create the right policy environment to allow for appropriate investments in research and development to enhance productivity and increase production.

Investment in agriculture in Africa must focus on creating a dynamic smallholder sector. A vibrant rural sector generates local demand for locally produced goods and services. In turn, this can spur sustainable non-farm employment growth in services, agro-processing, and small-scale manufacturing. This is crucial for rural employment, without which poor rural young people will be driven away from their communities in search of work in the cities.

Agriculture, predominantly on a small scale, accounts for about 30% of sub-Saharan Africa’s GDP and at least 40% of export value. In a number of small countries in Africa, agriculture plays an even greater role, representing 80% or more of export earnings.

The potential in these numbers will remain untapped unless African countries put the right policies in place to help agriculture to develop and flourish. But transformation of African agriculture will not happen until the private sector is fully engaged in agricultural production, processing, and marketing. Governments must become more investor-friendly to attract greater private-sector interest.

More broadly, African countries need to put their political and economic houses in order. They must continue to deepen the foundations of democracy and ensure the political stability that is so critical to economic growth. It is also crucial that they continue to improve their systems to create an enabling environment for dynamic rural growth to transform subsistence farmers into entrepreneurs.

Given their central role not only as mothers and caregivers, but also as farmers, rural women hold the key to food security. That is why any nation that does not provide opportunities for women will not reach its full potential. Significant progress must be made in Africa to advance both women’s empowerment and their status in society – particularly with regard to land and credit.

Finally, although investment in development assistance is key to supporting Africa’s advancement, nations will ultimately have to take responsibility for their own development. No nation, no people, ever experienced growth that sprang solely from external support.

So Africa’s development must be made in Africa, by Africans, for Africans. Every tree, every plant, must be fully rooted in its own soil to flourish. Change cannot be imposed from outside, it must be cultivated from within.

 

Major Crisis For Rossi and his E-Cats

Information from websites that monitor the development of the Rossi E-Cats (3 or 4 separate models) indicate that Rossi has sidelined the original “low-temperature” E-Cats in favor of developing the new 1200°C “Hot-Cat”. This new reactor would be the “Holy Grail” of energy production and supply all types of energy (heat, electrical, mechanical, etc.) for domestic and industry.
(from rossifocardifusion.com)

Apparently in frustration with the progress from Rossi, a private Swedish investors group sent a technician to monitor the testing of the new, high temp. reactor at Rossi’s Bologna facility. The INPUT power measured by the technician were 2 to 3 times higher than those mentioned in a report by the Rossi engineers. So, the ‘technician’ prepared a PRESS RELEASE that told the world about this discrepancy! The Swedish group promptly halted their involvement with Rossi.

If INPUT power is 2 to 3 times higher than Rossi is reporting ‘on all his reactors’, the calculated over-unity OUTPUT values are much, much smaller? Is this proof of deliberate fraud by Rossi? Can we rely on the ‘measurements’ by the technician to know that?

Rossi’s response is that Investors measurements were done on a new high-temp model, with higher operating temperature, different power supply and hydrogen supply. Also, the method of input measurement is now different from the earlier method where there was lower input power. Thus, the Rossi September 9 report reflected the earlier testing of another E-Cat.

Engineers working with/for Rossi acknowledges that there are problems with measurement of input power. “The problem was solved (after the Swedish incident) through use of a VARIAC (variable voltage and current transformer) to stabilize the current and voltages,” “Cures”, the test engineer said.

Apparently Rossi let his guard down by allowing this unknown ‘technician’ to wander around the shop and grab a quick (probably a clamp-on meter) INPUT reading on the Hot-Cat? Without knowing what is in that power supply, how could anyone measure and calculate accurate INPUT values? All of these measurements; Technician’s and Rossi’s are of little value – only INDEPENDENT, THIRD-PARTY VALIDATION TESTING can be relied on for confirmation that the E-Cat and Hot-Cat are real and are a new science and technology ready for commercial use.

All we can do now is be patient and hope that Andrea Rossi can prevail and deliver his E-Cat technology for both domestic and industrial use. The world is counting on you Rossi. Be brave and be strong – don’t let this crisis stop you.

What is the Smallest Star?

The biggest stars in the Universe are the monster red hypergiants, measuring up to 1,500 times the size of the Sun. But what are the smallest stars in the Universe? (from universetoday.com)

The smallest stars around are the tiny red dwarfs. These are stars with 50% the mass of the Sun and smaller. In fact, the least massive red dwarf has 7.5% the mass of the Sun. Even at this smallest size, a star has the temperature and pressures in its core so that nuclear fusion reactions can take place.

One example of red dwarf star is the closest star to Earth, Proxima Centauri, located just 4.2 light-years away. Proxima Centauri has 12% the mass of the Sun, and it’s estimated to be just 14.5% the size of the Sun. The diameter of Proxima Centauri is about 200,000 km. Just for comparison, the diameter of Jupiter is 143,000 km, so Proxima Centauri is only a little larger than Jupiter.

But that’s not the smallest star ever discovered.

The smallest known star right now is OGLE-TR-122b, a red dwarf star that’s part of a binary stellar system. This red dwarf the smallest star to ever have its radius accurately measured; 0.12 solar radii. This works out to be 167,000 km. That’s only 20% larger than Jupiter. You might be surprised to know that OGLE-TR-122b has 100 times the mass of Jupiter, but it’s only a little larger.

And that is the smallest known star. But there are certainly smaller stars out there. The smallest theoretical mass for a star to support nuclear fusion is 0.07 or 0.08 solar masses, so smaller stars are out there.

Noted Women’s Rights Activist in Congo Eludes Group of Gunmen

A leading human rights activist from the Democratic Republic of Congo said on Friday that he had narrowly escaped what appeared to be an assassination attempt when gunmen infiltrated his home, took his children hostage and killed a security guard in a spray of bullets before fleeing in the family car. (from nytimes.com)

On Thursday evening, four or five unidentified gunmen entered the home of the activist, Dr. Denis Mukwege, 57, while he was out, forced his two daughters and their friend onto the floor, confiscated their telephones and threatened to shoot them if they made any noise, according to a statement from Physicians for Human Rights, a humanitarian organization based in the United States, and a neighbor.Dr. Mukwege, one of Congo’s most high-profile personalities and a past Nobel Peace Prize nominee, said in a telephone interview on Friday that when he pulled up to the gate at his home in Bukavu, in eastern Congo, about an hour later, he saw “very strange people.” The gunmen forced their way into his car, and one stepped out and trained his gun on the doctor. Then one of his security guards appeared out of nowhere. The gunman menacing Dr. Mukwege whirled around and opened fire on the guard instead, Dr. Mukwege said, then fired at him. “They were shooting bullets in my direction,” he said. He scrambled to get away, and the assailants ran out of ammunition without hitting him. “And then they just jumped again in the car.”

The three children were also unharmed, but Dr. Mukwege’s security guard — Papa Djef, as he was known to the family — was killed. “He was like my child,” Dr. Mukwege said. “He was really a brave man. He just paid his life to save mine.”

The Loongson Low Power MIPS Processesor

Loongson is a general purpose RISC processor. It is a 64-bit MIPS compatible processor, which is patented by MIPS Technologies. The silicon is designed by ICT/CAS China and manufactured by ST Microelectronics. The online retail price for Loongson-2F chip is about USD30~40, which is available from the Lemote’s online shop. Of course, you can order it in the name of STLS2F from ST as well.
(from dev.emcelettronica.com)

Loongson-2F, the latest version operates at 1.2 to 1.5GHz and only consumes 5 watts. Additionally, Loongson-2F also supports DDR2 and USB2.0. As a RISC processor, Loongson processor is struggling on its way to the market for a long time. As we know, the processor market is highly competitive. ARM has been a de facto standard RISC processor IP in mobile terminals and embedded SoC. MIPS is not the market leader. It is mainly used in digital video and telecommunication segments like STB, HDTV, IPTV, DSL modem, laser print and video game consoles (Sony PS/PSP). MIPS processors are usually available in IP and embedded SoC, you can find some old types available for legacy SGI workstation, Windows CE PPC and HPC. AMD acquired Alchemy MIPS processor in PMP and HDTV, and finally it got rid of this business line before long. Sometimes, I wonder why AMD bought Alchemy at the very beginning.

Although it is hard to find the market opportunities for MIPS. ICT offers a series of open source MIPS based designs for NAS, Linux desktop PC, thin client terminal and others with their own Loongson processor family. Recently, they start to promote the MIPS Netbook to the consumer market. The price is comparable to the ATOM/Nano based Netbook, many local Linux developers enjoy it very much. Because it is very hard to buy a high speed MIPS board with low price. Can you find a 300USD evaluation board for 1.5GHz MIPS processor? The system has been installed with Debian MIPS distribution and native GCC for MIPS. Compare to an ordinary x86 Netbook, the user experience is same. MIPS still have major OS support from Windows CE and Linux. Most of the popular software components are available on these platforms. Netbook and MID are great chances for MIPS to return to the desktop/mobile computing market. However, I can name many limitations for MIPS: you can not play Real Video and QuickTime, you can not run WINE, you can not use commercial DLLs for x86 and Windows, and you may face to the driver issues. The MIPS Netbook only fits the requirements for the highly experienced communities or the people who have no PC experiences at all (like my parents) and just want to check their emails or browsing. The MIPS device is good for them because it is totally virus-free.

I don’t want to promote MIPS IP or Loongson Netbook here. I also don’t think MIPS Netbook can win the market. Non-x86 structure can not beat x86 in Netbook, because people consider Netbook a low-cost laptop PC. However MIPS should focus its advantage on digital video segments, including media adapter, PMP and PND. And so we, as the engineers, let us check the specification and find out its opportunities.

– MIPS-III 64 bit superscalar architecture
– 900 MHz clock frequency
– Single/double precision floating point units
– New streaming multimedia instruction set support (SIMD)
– 64 KB I-cache, 64KB D-cache, on-chip 512 KB unified L2 cache
– On chip DDR2 667 and PCI-X controller
– 4W@900MHz power consumption:
– Voltage/frequency scaling
– Standby mode support
– L2 cache disable/enable option
– 90 nm process technology
– JTAG interface

Apparently, this chip has advantage on 64-bit performance, FPU, SIMD over mainstream ARM products. Meanwhile it has much lower power consumption over x86 processor. It requires 3rd party north/south bridges (VIA) to complete the system design. A Chinese company HiSand also developed a Loongson-1 based SoC for Internet Radio, digital photo frame and other consumer products. Its HS3210 has integrated a lot of peripherals on-chip with a 266MHz MIPS core. It is the first step of the right direction. Only if its MIPS SoC wins the market, the Loongson can live on. I have no doubt about the market capacity of consumer electronics, if HS3210 has good quality with low price as they claimed, it is make sense to buy a Loongson computer/Netbook for development purpose with the native toolchains. Loongson also offers a simulator so you can evaluate the system.
