- Iran to Step Up Nuclear Fusion Research
Head of Iran's Atomic Energy Organization says country stepping up research on nuclear fusion in bid for alternative energy sources ヘッドは、イランの原子力機関の国が代替エネルギー源の入札に核融合の研究を強化している
- Iran says it gains access to nuclear fusion technology: atomic organization
Atomic Energy Organization of Iran (AEOI) announced Thursday the Islamic Republic has manufactured a machine to produce nuclear fusion laser.
In an announcement posted on its website, AEOI said that researchers have conducted researches in nuclear fusion using inertial electrostatic confinement method, said the announcement.
The research center for science and technology at AEOI designed and manufactured this machine which places Iran the sixth after the United States, Japan, South Korea, ... イランの原子力機関が（AEOI）木曜日イスラム共和国は、核融合レーザーを製造する機械等を製造したことを発表しました
- Nuclear fusion – what is it worth? | Steven Cowley
Experiments in fusion power have at last started to prove its viability. It would be foolish not to continue funding researchFusion is arguably the perfect way to power the world. For one thing, there is enough fusion fuel to supply all of the world's energy needs for millions of years. Furthermore, it produces no environmentally damaging wastes, no carbon dioxide emissions and there could be no accidents that require evacuating the population surrounding a fusion power plant. Fusion plants would also not need significant land area, and fusion fuels (lithium and deuterium) are available in seawater. Unfortunately, it is hard to make fusion work. Indeed, after more than 60 years of fusion research, no device has yet made more energy than it consumes.Iter, the next fusion machine and the first to be built as an international collaboration, is designed to demonstrate the scientific feasibility of net energy production. It is expected that Iter will produce about 500MW of fusion power – 10 times the input power. Just as importantly, it will show how to integrate the many cutting-edge technologies required for efficient and reliable future power station designs. Put simply, it is the big step needed to prove the viability of fusion as a commercial energy source.Unfortunately, Iter's construction expenses have risen from about €5bn to over €13bn and the cost overruns have prompted some to question why chasing nuclear fusion is a priority. How sure are we that Iter will work? Could this money be spent more wisely in other areas of energy research, such as renewables or new fission? My answer is that fusion is more than desirable. It may be crucially necessary.Burning coal, oil, or natural gas generates 80% of the world's primary energy. This simply can't continue much longer. 核融合発電の実験では最後に、その可能性を証明するようになったのです
- Palestine papers: the settlements up for discussion listed and mapped
The Palestine Papers identify land and settlements for potential swaps. See where they are• Get the dataThe Palestine Papers have set the news agenda for today with details emerging of how Palestinian negotiators agreed to Israel annexing all but one of the settlements built illegally in occupied East Jerusalem.Al Jazeera and the Guardian have shared access to thousands of documents in the biggest ever leak over the Middle East peace talks. You can see an interactive guide to them here.As reported today, the Israeli negotiator Tzipi Livni is recorded as dismissing the offer out of hand because the Palestinians had refused to concede Har Homa, as well as the settlements at Ma'ale Adumim, near Jerusalem, and Ariel, deeper in the West Bank. Israel's position was fully supported by the Bush administration.We've extracted the key data for you from this document - which outlines the places Palestinian negotiators were willing to negotiate over. Our map (shown above) is based on a background image from B'Tselem, which produces incredibly detailed maps of the area - the same map seems to have been used in the leaked document.A Google Fusion tables map of the areas shows how they are in the most hotly-contested part of the region - although Fusion tables does not appear to have any roads or town names for Israel. There's a much more useful version produced by Al Jazeera here.The key data appears to be that:• Israel and Palestine would swap 119 square KM• 56,000 settlers (12%) would be evacuated, leaving 413,000 (88%) in situThe full data is below.

- Iran claims to have built fusion reactor
Tehran claims yet another nuclear breakthrough but is there anything to it?While the world was watching Egypt tonight, Iran snuck out a claim that it has built a nuclear fusion device. Press TV reports that:The device uses Inertial Electrostatic Confinement method and can produce isotopes and radioisotopes used in diagnosing and curing cancer. The US, Japan, South Korea, Australia and France are the only countries which boast fusion technology. Press TV did not mention North Korea, which claimed to have mastered fusion technology last May. The Iranian boast is not so bold, though. Tehran is not saying it can generate energy through fusion, simply that it can manufacture medical isotopes. The political significance of the claim is clear. It suggests Iran would not need outside help for its Tehran Research Reactor - a need that was once seen as the basis for a short-term compromise on Iran's nuclear programme, or a confidence-building measure at least. But is the claim feasible? There are many bench-top experiments in fusion going on around the world, and at least one relatively low-tech design which seems to resemble the device Press TV is describing, and which has been shown to be a viable neutron source. But can one of these designs make medical isotopes, or is it a hoax? I would be interested to hear from experts.IranNuclear powerJulian Borgerguardian.co.uk © Guardian News & Media Limited 2011 | Use of this content is subject to our Terms & Conditions | More Feeds
