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-

The American Spectator : A True Energy Policy - 0 views

    Excellent over view of shale gas and compressed natural gas dynamics including conversion kits for automobiles and truck fleets. THE ONLY LOGICAL ANSWER to bridge the conversion from oil based fuels to paradigm alternatives lies in the conversion of personal transportation to the use of natural gas. Consider the following reasons: (long list) ONE WEEK AFTER Obama's energy policy speech, March 31, 2011, at Georgetown University, a bi-partisan group of more than 150 Members of Congress introduced HR.1835, with Rep. John Sullivan (R-OK) as the primary sponsor. The NAT GAS Act (New Alternative Transportation to Give Americans Solutions) Act, is the culmination of efforts of T. Boone Pickens to promote his "Pickens Plan" for changing the focus of American energy consumption. The NAT GAS Act provides incentives for using natural gas in vehicles, purchasing natural gas vehicles, installing natural gas refueling stations, and producing natural gas vehicles in America. The problem is that Obama and his energy secretary do not actually support HR 1835!  The speech was just a ruse.  Watch what he does, not what he says.  CNG-Compressed Natural Gas

Miniature Nuclear Plants Seek Approval to Work in U.S (Update1) - BusinessWeek - 2 views

  •  
    Manufacturers of refrigerator-sized nuclear reactors will seek approval from U.S. authorities within a year to help supply the world's growing electricity demand. John Deal, chief executive officer of Hyperion Power Generation Inc., intends to apply for a license "within a year" for plants that would power a small factory or town too remote for traditional utility grid connections. The Santa Fe, New Mexico-based company and Japan's Toshiba Corp. are vying for a head start over reactor makers General Electric Co. and Areva SA in downsizing nuclear technology and aim to submit license applications in the next year to U.S. regulators. They're seeking to tap a market that has generated about $135 billion in pending orders for large nuclear plants.

Space storm alert: 90 seconds from catastrophe - space - 23 March 2009 - New Scientist - 0 views

    Interesting article from New Science describing how a "coronal mass ejection" from the Sun could melt down the electrical power gird. ".... Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences..." The article does offer a solution: upgrade the ACE solar satellite, to detect an electro magnetic surge and provide power grid operators with about 15 minutes to shut down their systems. The article does not discuss another possible option: stop building centralized power sources that demand increasingly massive power grids. Instead, concentrate on meeting energy needs using localized sources of power; like the highly portable Hyperion Power Module.

Next Generation Nuclear Power: Scientific American - 0 views

    Six page article from 2003 provides an in depth discussion on existing and Future Nuclear Systems:  "In Response to the difficulties in achieving sustainability, a sufficiently high degree of safety and a competitive economic basis for nuclear power, the U.S. Department of Energy initiated the Generation IV program in 1999. Generation IV refers to the broad division of nuclear designs into four categories: early prototype reactors (Generation I), the large central station nuclear power plants of today (Generation II), the advanced lightwater reactors and other systems with inherent safety features that have been designed in recent years (Generation III), and the next-generation systems to be designed and built two decades from now (Generation IV) [see box on opposite page]. By 2000 international interest in the Generation IV project had resulted in a nine-country coalition that includes Argentina, Brazil, Canada, France, Japan, South Africa, South Korea, the U.K. and the U.S. Participating states are mapping out and collaborating on the research and development of future nuclear energy systems."
