Teenager Designs Safer Nuclear Power Plants - Yahoo! News - 3 views

  •  
    Very interesting presentation at the TED Conference.  Not quite a nuclear battery, but a really good redesign of nuclear power systems. excerpt: "Instead of finding a new way to boil water, Wilson's compact, molten salt reactor found a way to heat up gas. That is, really heat it up. Wilson's fission reactor operates at 600 to 700 degrees Celsius. And because the laws of thermodynamics say that high temperatures lead to high efficiencies, this reactor is 45 to 50 percent efficient. Traditional steam turbine systems are only 30 to 35 percent efficient because their reactors run at low temperatures of about 200 to 300 degrees Celsius. And Wilson's reactor isn't just hot, it's also powerful. Despite its small size, the reactor generates between 50 and 100 megawatts of electricity, which is enough to power anywhere from 25,000 to 100,000 homes, according to Wilson. Another innovative component of Wilson's take on nuclear fission is its source of fuel. The molten salt reactor runs off of "down-blended weapons pits." In other words, all the highly enriched uranium and weapons-grade plutonium collecting dust since the Cold War could be put to use for peaceful purposes. And unlike traditional nuclear power plants, Wilson's miniature power plants would be buried below ground, making them a boon for security advocates. According to Wilson, his reactor only needs to be refueled every 30 years, compared to the 18-month fuel cycle of most power plants. This means they can be sealed up underground for a long time, decreasing the risk of proliferation. Wilson's reactor is also less prone to proliferation because it doesn't operate at high pressure like today's pressurized-water reactors or use ceramic control rods, which release hydrogen when heated and lead to explosions during nuclear power plant accidents, like the one at Fukushima in 2011. In the event of an accident in one of Wilson's reactors, the fuel from the core would drain into a "sub-critical" setting- or tank-

Virtual power plants could tame coming grid chaos - tech - 11 June 2009 - New Scientist - 0 views

  • Fears over energy security and climate change have led to record investment in renewable energy. But a major problem threatens to stall progress towards a more sustainable future: national electricity grids are far from ready to cope with the variable output from the new technologies. A solution might be at hand, though, and would not involve radical changes to the existing infrastructure. Treating groups of dispersed power sources, such as solar and wind generators, as a single entity could solve the problem, creating the virtual equivalent of a single large power station.

Japan Proposes Wind, Geothermal Power Feed-in Tariff (Update1) - Bloomberg.com - 0 views

  •  
    "A Japanese trade ministry panel today proposed expanding the feed-in tariff to require utilities to buy electricity at a premium from hydropower stations, wind turbine and geothermal operators. Utilities may have to buy renewable power at between 15 yen (17 cents) and 20 yen a kilowatt hour, according to a report released in Tokyo today. The incentive program would run for between 10 and 20 years, it said. The government wants to supply 10 percent of the country's primary energy from renewable sources by 2020, compared with about 3 percent in 2007, according to the International Energy Agency. The proposed tariff compares with 5 to 7 yen a kilowatt hour utilities pay for nuclear power and about 8 yen for oil- fired generation, said Tomohiro Jikihara, an analyst at Deutsche Securities Inc. in Tokyo.

Europe could create a 100% renewable electricity supply by 2050 - PIK Research Portal - 1 views

  •  
    " Renewable energy sources could be used at scale by 2050 if supported by an efficient European transmission grid and a single European power market united with similar grids and markets in North Africa. This is shown in a new report released last week by PricewaterhouseCoopers. A group of energy and climate experts from the company in collaboration with researchers of the Potsdam Institute for Climate Impact Research (PIK), the International Institute for Applied Systems Analysis (IIASA) and the European Climate Forum (ECF) have examined possible transformation paths for the European and North African power sector. A transformation of the power sector based on one hundred percent renewables would address energy security and supply concerns while decarbonising electricity generation and at the same time reduce energy poverty, the report says."

Efficiency debate: The pros and cons of consumer electronics - 0 views

  •  
    The American Council for an Energy-Efficient Economy issued a report yesterday touting the role that semiconductor-based technologies have played in making the U.S. economy more efficient. At the same time, the International Energy Agency issued its own report calling on governments around the world to be more aggressive with efficiency standards for ICT and consumer electronics, which are expected to demand twice as much power by 2022 and three times as much by 2030 - creating a need for another 280 gigawatts of power generation (i.e. like adding another Japan to the world, or more than 230 nuclear reactors). "This will jeopardize efforts to increase energy security and reduce the emission of greenhouse gases," according to an IEA news brief.

Efficiency key to making Denmark fossil fuel-free by 2050, says report - 0 views

  • In this ‘green’ future, electricity will comprise 40-70% of energy consumption, up from around 20% now. And a large part of this electricity will come from offshore wind farms, which the report highlights as an economically viable option for Denmark.The Klimakomissionen says many more turbines will have to be erected to cover up to half of the country’s energy consumption.Meanwhile, the energy system will have to become much more flexible and intelligent to cope with the fluctuation of wind energy.Technologies such as smart electricity meters, time-controlled recharging for electric cars and heat pumps in combination with heat storage systems will be crucial to the new energy order.The report says that biomass will play an important role as back up to wind power and to supply heating for homes, along with solar heating, geothermal energy and heat pumps, which will serve district heating systems.

How to unplug yourself from the grid - 0 views

  • "I HAVEN'T paid an electricity bill since 1970," says Richard Perez with noticeable glee. He can afford to be smug. While most of us fretted over soaring utility bills this year, he barely noticed. Nor is he particularly concerned about forecast price hikes of 30 to 50 per cent in 2009. Perez, a renewable-energy researcher at the University at Albany, State University of New York, lives "off-grid" - unconnected to the power grid and the water, gas and sewerage supplies that most of us rely on. He generates his own electricity, sources his own water and manages his own waste disposal - and prefers it that way. "There are times when the grid blacks out," he says. "I like the security of having my own electricity company."

Electricity regulator under pressure - 0 views

  • One can see where the Minister is coming from. Current electricity prices are too low to fund new investment necessary to restore supply security. Average generation prices of around 12 c/kWh are less than half the cost of new coal-fired generation plant. The recently installed turbines, which are keeping the lights on over the Cape winter, produce power at a cost much higher than even the highest industrial tariff.

Pambazuka - Profits before people: The great African liquidation sale - 0 views

  • So what do the world’s great investors have their eyes on in Africa, in addition to the usual natural resources – minerals, petroleum and timber – that they’ve always coveted? In a word, land. Lots of it. The land-grabbing 'investors' are purchasing or leasing large chunks of African land to produce food crops or agrofuels or both, or just scooping up farmland as an investment,

      Biofuels are not sustainable energy. They do not protect food resources.
  • At the moment, the grabbing of Africa’s land is shrouded in secrecy and proceeding at an unprecedented rate, spurred on by the global food and financial crises. GRAIN, a non-profit organisation that supports farm families in their struggles for community-controlled and biodiversity-based food systems, works daily to try to keep up with the deals on its farmlandgrab.org website.[vi]
  • Apart from the African governments and chiefs who are happily and quietly selling or leasing the land right out from under their own citizens, those who are promoting the new wave of rapacious investment include the World Bank, its International Finance Corporation (IFC), the European Bank for Reconstruction and Development and many other powerful nations and institutions. The US Millennium Challenge Corporation is helping to reform new land ownership laws – privatising land – in some of its member countries. The imported idea that user rights are not sufficient, that land must be privately owned, will efface traditional approaches to land use in Africa, and make the selling off of Africa even easier. GRAIN notes the complicity of African elites and says some African 'barons' are also snapping up land.

    "it was all summed up clearly for me by members of COPAGEN, a coalition of African farmer associations, scientists, civil society groups and activists who work to protect Africa's genetic heritage, farmer rights, and their sovereignty over their land, seeds and food. All these knowledgeable people have shown me that the answer is quite straightforward: many of those imported mistakes, disguised as solutions for Africa, are very, very profitable. At least for those who design and make them."
