    Artificial Photosynthesis: Solar-Powered Green Chemistry Rehabilitates CO2
    A breakthrough in artificial photosynthesis has been achieved with the development of a hybrid system of semiconducting nanowires and bacteria that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and liquid fuels.

    The system mimics the natural photosynthetic process by which plants use the energy in sunlight to synthesize carbohydrates from carbon dioxide and water but this artificial photosynthetic system synthesizes the combination of carbon dioxide and water into acetate, the most common building block today for biosynthesis.

    By combining biocompatible light-capturing nanowire arrays with select bacterial populations, the new artificial photosynthesis system offers a win/win situation for the environment: solar-powered green chemistry using sequestered carbon dioxide. The system starts with an "artificial forest" of nanowire heterostructures, consisting of silicon and titanium oxide nanowires.

  • Decommissioning work at the Fukushima Daiichi nuclear power plant has suffered a setback after a robot sent in to a damaged reactor to locate melted fuel stalled hours into its mission and had to be abandoned.

    The plant’s operator, Tokyo Electric Power (Tepco), said the robot stopped moving on Friday during its first inspection of the containment vessel inside reactor No 1, one of the three reactors that suffered meltdown after the plant was struck by an earthquake and tsunami in March 2011.

    Tepco, which recently conceded that the technology for robots to retrieve the nuclear fuel had yet to be developed, said on Monday it would cut the cables to the stranded robot and postpone a similar inspection using a separate device.

    Developed by Hitachi-GE Nuclear Energy and the International Research Institute for Nuclear Decommissioning, the robot was supposed to be able to function for about 10 hours even when exposed to radiation at levels that would cause ordinary electronic devices to malfunction.

    The “transformer” robot, which can alter its shape depending on its surroundings, was sent in to photograph the inside of the reactor containment vessel and record temperatures and radiation levels.

    More than four years after Fukushima Daiichi suffered the worst nuclear accident since Chernobyl a quarter of a century earlier, radiation levels inside the three reactors are still far too high for humans to enter.

    Tepco is pinning its hopes on a new generation of remote-controlled robots, the first of which will monitor the state and location of the melted fuel before others remove it from the reactors’ outer containers.

    When somebody points out that China's per capita emissions are lower than ours, I reply, "Yes, but they are growing their per-capita emissions seven times faster than we are as well!"

    Perhaps China needs to steal more clean, nuclear technology from the US.

    Big GE Deal

    If you were a long term investor in USEC and Silex, you really did lose your shorts! Sorry to hear that.

    Going forward, I think GE halting their Silex Plant was kind of a death knell for Silex. I wouldn't be looking to LEU to restore my fortunes any time soon.

    The first rule of investing is to diversify. If your funds are limited, you can buy a sector ETF like UPRO which is triple leveraged to the S&P 500. It was up 54% in the past 12 months. Of course, if the market is down this year, UPRO could be down three times as much.

    The only thing you need to know about Obamacare is that it will dump trillion$ of taxpayer dollars into healthcare. The triple leveraged healthcare ETF, ticker CURE, is up 122% in the past twelve months. It's up 700% in the past five years.

    Good luck!

  • China this year surpassed the U.S. as the world's largest emitter of greenhouse gases.

    Despite the surfeit of smut, the average Chinese citizen is responsible for a fraction of the greenhouse emissions of the average American—and the country is not bound by any international treaty to reduce its emissions. Yet, the government has launched a pilot project to address the problem by capturing and storing the carbon dioxide (CO2) produced by using coal as a fuel for electricity generation at a power plant dubbed GreenGen.

    The project in the port city of Tianjin will proceed in three phases. First, a consortium of power and coal companies will fork over funds to construct a so-called integrated gasification combined cycle (IGCC) power plant (in which coal is turned to gas and pollutants removed before burning) that is capable of producing 250 megawatts of electricity. Such technology could cut acid rain–causing sulfur dioxide emissions by more than 90 percent, smog-forming nitrogen oxides by 75 percent, and—ultimately—capture more than 80 percent of the CO2 normally produced by combustion, storing it in nearby depleted oil fields by 2015.

    China's $1 billion GreenGen power plant became the world's leading clean coal technology project after the U.S. government in February pulled the plug on FutureGen, a similar program that lost steam as the costs for building the demonstration plant in Mattoon, Ill., skyrocketed. Yet, the U.N. Intergovernmental Panel on Climate Change (IPCC) and leaders of the world's eight richest nations, including President Bush, among others, have called the development of clean coal technology essential to preventing the consequences of climate change.

    But completing GreenGen may yet prove a challenge as well. "There's no co-benefit to doing the carbon capture and storage," says energy technology expert Kelly Sims Gallagher of the Harvard Kennedy School of Government.

    GE halted production on its Silex plant, but may still be interested in a uranium enrichment plant. GE just raised a buttload of money by selling a bunch of assets.
    If Silex doesn't work on a commercial scale, GE can take advantage of LEU's financial problems and pick up the best enrichment technology for pennies-on-the-dollar.

    Just speculation. GE is still claiming Silex works just fine...

    The United States expanded its lead as the world's largest producer of oil and natural gas last year as output from fracking fields surged, the US Department of Energy reported Tuesday.

    While hydrocarbon production in Russia and Saudi Arabia remained relatively flat, US output, by the British thermal unit (Btu) measure of energy content, gained about 10 percent to nearly 55 quadrillion Btu last year.

    That increase represented a 1.6 million barrel a day rise in crude production and a 13.9 billion cubic feet a day rise in natural gas production. US output now stands at about double that of Saudi Arabia.

    US production is evenly split between crude oil and natural gas, according to the EIA. In Russia output is also balanced between oil and gas, while Saudi Arabia mainly produces crude oil.

    The US production gains came despite a 50 percent fall in oil prices during the second half of the year, the EIA noted.

    One aspect of the proposed Iranian nuclear agreement is that Iran would turn over its 20% enriched uranium to Russia for reprocessing. Centrus Energy (when it was USEC) acted as the sole agent for selling Russian SWU under the Megatons to Megawatts Program. Maybe somebody is speculating that the agreement will be revised.

    I'm not sure anyone knows how much of this enriched uranium Iran has produced.

  • Plants remain offline following Fukushima crisis until clearance in safety review
    Published: 14 hours ago
    (Anadolu Agency) A Japanese nuclear regulation watchdog created after the Fukushima disaster has accepted a report saying that a reactor at a plant on the Sea of Japan coast is situated above an active geological fault.

    The report, submitted to the Nuclear Regulation Authority, explained that at least one fault under the No. 2 reactor of the Japan Atomic Power Co.’s Tsuruga plant could move in the future, Kyodo News reported.

    After the 2011 Fukushima nuclear crisis, all commercial reactors in the earthquake-prone country remain offline until their clearance in the regulator’s safety review.

    It is prohibited for reactors and other safety-requiring facilities to be built directly above active faults.

  • (Reuters) - The European Union has backed Euratom's decision to block Hungary's 12 billion euro nuclear deal with Russia, a move that could worsen the situation between the Kremlin and Brussels, the Financial Times reported.

    The decision, which was not made public, was taken at a meeting in Brussels last week, the newspaper said.

    Hungary requested that Euratom, the European Atomic Energy Community, revive the decision, the newspaper said, citing people close to talks.

    Russia and Hungary agreed last year to build two units with 1,200 megawatts capacity at Hungary's Paks nuclear power plant, a decision that was criticized by opposition parties.

    Hungary, which relies on Russia for most of its gas and oil imports, agreed for a deal with Russian state-owned nuclear company Rosatom to build the units.

    Blocking the deal would put a hold on Hungary's plans to import fuel exclusively from Russia. Hungary will now have to negotiate a new fuel contract or pursue legal action against the commission, the newspaper said.

    "If the Russians now refuse to modify the original contracts, this will be the end of the road for the project,” said Javor Benedek, a Hungarian member of the European Parliament's Green group, the newspaper reported.

    The newspaper said the commission launched a probe into the deal after Budapest awarded the bulk of contracts for two reactors to Rosatom without a public competition.

    The European Commission, Euratom and Rosatom could not be immediately reached for a comment.

  • are politicians. Maybe some report or bill favorable to Centrus is moving through Congress and they are buying LEU today. It could be an addendum to an appropriations bill currently being debated. Congress exempted itself from insider trading rules.

    On the other hand, it could be a "fat finger" error where somebody placed a market order for more LEU stock then was available. Always place limit orders for thinly traded stocks.

    Finally, the recent rise in stock price may have spooked a big short seller who closed his position and started a short squeeze.

    I would LOVE to see LEU close above $5 for a few days. We may actually get some institutional buying!
    Congrats to the longs today!

    Bid $4.46, ask $4.90

    A trade occurs when bid price meets ask price (I'm sure you know that). A wide spread between bid and ask means no shares are currently being exchanged. Sunday afternoon the bid is $4.01 and the ask is $11. I try to avoid thinly traded stocks.

    There are other ways to trade stocks such as black pools and options exercises, but I don't think they affect LEU.

    Check out JBLU, up 26% in 3 months. Airlines benefit from cheap oil.

    One popular theory expressed on this board is that Silex was a flop but GE won't publicly admit it because the threat of the new ACP becoming essentially worthless will drive LEU into bankruptcy and GE can buy its assets for pennies on the dollar. Shareholders would be essentially wiped out by bankruptcy, so I wouldn't own the stock for that reason.

    GE has a lot of influence with the Obama Administration so they may be working behind the scenes to keep the Energy Debt from coming to Centrus's rescue.

    On the other hand, the company;s market cap has fallen so much it would be ridiculous for GE to wait longer if it was interested in buying out Centrus.

    There was a 1000% short squeeze a couple of years ago

    Basically, once the new plant is built they will have the most energy-efficient enrichment facility in the world. Unfortunately, they are taking so long to build it they run the risk of losing their technological edge.
    The company is hoping for a government loan guarentee but the Obama Energy Dept passed it over in favor of wind and solar pojects.
    GE owns the rights to the Silex process which is even more energy efficient but may not be practical outside a laboratory. GE pulled the plug on the plant they were building, but Silex remains a threat.
    Meanwhile nuclear power has struggled with bad press from Fukushima and cheaper alternatives like natural gas from fracking.

    Bottom line, LEU is a lottery ticket. Ignore the pumpers and the bashers.
    LEU is a newsdriven stock that rarely has any news.

    Physicists are getting antsy. Their most highly prized tool for studying the smallest bits of nature—the Large The Large Hadron Collider (LHC) particle accelerator—has been shut down since the end of 2012 for $163 million worth of upgrades. But within two months it will be back with a vengeance, colliding protons at mind-numbing energies that have never been achieved in a man-made machine. Physicists hope that these energies will be enough to produce new particles or phenomena that expose secrets the universe has thus far been unwilling to give up. In particular, the upcoming run at the LHC could yield evidence for an idea called supersymmetry, which would be upheld if extra particles and dimensions of matter show up—and which would explain many puzzling facets of the cosmos.

    The largest machine on Earth, the LHC comprises an underground loop with a circumference of 27 kilometers beneath France and Switzerland. Inside the ring, first opened in 2008, protons sent off in opposite directions accelerate to near light-speed then smash head-on into one another and explode. In the aftermath their energy is converted into mass in the form of particles—some of which are exotic species rarely seen in nature. One such, the Higgs boson, revealed itself at the collider in 2012 after theorists predicted its existence more than four decades earlier. Now scientists are hoping the LHC can reprise the feat and expose more new particles—perhaps even other, heavier versions of the Higgs boson.

    LHC’s energy boost might make these new particles accessible. Its protons used to collide at energies of 8 trillion electron volts (TeV), but the machine’s electromagnetic fields will now inject them with more energy, causing them to crash together at 13 TeV.

    The idea of powering humanity by gathering an endless supply of solar energy from space has taken a huge step towards becoming a reality. Scientists working for JAXA, Japan's space administration, have announced a major breakthrough in wireless power transmission ... in that they've actually been able to do it with a high degree of accuracy for once. The team reportedly beamed 1.8 kilowatts, enough juice to power an electric tea kettle, more than 50 meters to a small receiver without any wires. Up next: scaling the technology for use in tomorrow's orbital solar farms.

    The researchers were able to do so by first converting the electrical signal to microwaves, then beaming them to a remote receiver, and finally converting them back into electrons. This successful experiment is the first time scientists have been able to move electrons over any appreciable distance with such a high degree of accuracy, one JAXA researcher explained to the AFP.

    This was much talked about in the '70's but never came to fruition. The program aims to harness the constant supply of solar energy directly from space using orbital solar farms, then beaming it back to Earth (and into a global grid) via microwave transmission. What's more, these orbital arrays would never have to deal with obscuring cloud cover or darkened nights as their terrestrial counterparts do.

    I'm guessing Al Gore will say it causes Global Warming.

    China Approves Units 5 And 6 At Hongyanhe NPP

    On the eve of the fourth anniversary of the Great East Japan Earthquake, the state-owned China General Nuclear Power Corp. announced that it had government approval to build to new reactors in the northeastern province of Liaoning.

    The expansion project involves a fifth and sixth reactor at the Hongyanhe nuclear power station.

    China's National Development and Reform Commission approved the plant expansion after a four-year hiatus from nuclear plant approvals, including a two-year moratorium that was prompted by the 9-magnitude earthquake that lead to the crippling of the Fukushima Daiichi nuclear power station.

    The official moratorium on plant approvals in China was lifted in 2012 after safety standards were revised. Construction of plants begun in 2013 involved approvals given before the March 2011 earthquake. Construction also continued at Hongyanhe, where Units 3 is expected to go online this year and Unit 4 is still being built. Units 1 and 2 have been operational since 2013 and 2014, respectively.

  • Estimates of the chance of a magnitude 8.0 or greater earthquake hitting California in the next three decades have been raised from about 4.7% to 7%, the U.S. Geological Survey said Tuesday.

    Scientists said the reason for the increased estimate was because of the growing understanding that earthquakes aren’t limited to separate faults, but can start on one fault and jump to others. The result could be multiple faults rupturing in a simultaneous mega-quake.

    Stated another way, the chance of an 8.0 or greater quake in California can be expected once every 494 years. The old forecast calculated a rate of one 8.0 or greater earthquake every 617 years.

    “The new likelihoods are due to the inclusion of possible multi-fault ruptures, where earthquakes are no longer confined to separate, individual faults, but can occasionally rupture multiple faults simultaneously,” said USGS seismologist Ned Field, the lead author of the report.

    “This is a significant advancement in terms of representing a broader range of earthquakes throughout California’s complex fault system.”

    The report says that past models generally assumed that earthquakes were confined to separate faults, The report says that past models generally assumed that earthquakes were confined to separate faults, or that long faults like the San Andreas ruptured in separate segments.

    But recent large California earthquakes showed how earthquakes can rupture across multiple faults simultaneously. Many are in the Los Angeles area.

    Note: I know they closed San Onofre Nuke Plant. Are their any other nukes in California?
