  1. You will now notice that the Construction Intelligence Center website has again been updated for both Paducah and Wilmington since I last posted it here! http://www.construction-ic.com/HomePage/Pr...rview%2F151013# http://www.construction-ic.com/HomePage/Pr...rview%2F168133# You will notice that they have changed the wording from this -: GE Hitachi Nuclear Energy (GEH) is planning to construct a laser enrichment facility in Kentucky, the US. To this -: Global Laser Enrichment (GLE), a joint venture between General Electric Co. (GE), Hitachi Ltd and Cameco, is planning to construct the Laser Uranium Enrichment Facility in Kentucky, the US. See how they have now broken up the ownership now of GLE into seperate entities, I reckon one of those three companies is leaving, I think it may be Hitachi who may be selling their share, that would effectively mean that GEH is leaving wouldn't it? I very much doubt that GE would ever sell it's controlling interest of it's 51% holding in GLE and then let another company build a laser enrichment plant on GE land (Their Land), I don't believe for one minute that could or would ever occur? Also in an earlier version of the Construction Intelligence Center release about Paducah, they said that the NRC will be providing the License for it to GLE in September 2016. So we may get to see something next month, in other documents it said that the NRC license for Paducah would be provided BY November 2016, so I guess September 2016 would still fit that bill BY November wouldn't it?
  2. Regarding the ownership structure of GLE, I am of the opinion that it may be Hitachi pulling out? which in effect would still leave GE or GENE in particular with the 51% holding still in place? I could see a company like Converdyn who would have some great synergies with GLE/GNF-A being a company that would be interested? they are a company that would also have a great deal to lose if recycling gets up and they were not part of this? they would also have deep pockets, they are owned by General Atomics and Honeywell, as an aside they also make the drone Predator for the US military. I really can't see GE who also hold the license to the Silex process pulling out and then letting some other company build a laser enrichment plant on their land (which as you can see is still happening), it would not add up in my book, I can see Hitachi selling their part, they will need funds shortly to start building the first PRISM reactor in the US, I will show some links on that later' Can anyone here see that if you took out only Hitachi, you would have effectively taken out GEH and the GE component would then come under GENE possibly? I reckon in the end we may get to see four companies owning GLE GE/GNE 51% Cameco 25% Converdyn say 21% and Silex say 4% or somthing along those lines maybe? I believe there may also be a reason why Silex get to own a certain percentage for a very small outlay? It was done for a reason and I think I know what the reason was, it relates to the sudden increase of SP in SLX, we then had the GEH announcement, I believe it had the desired effect! Have a look at page 62 where it shows the ownership structure of GLE http://www.nrc.gov/docs/ML1122/ML11229A173.pdf
  3. If you look at the company structure, I believe that GEH were always going to leave at some point? but I very much doubt that GE will be parting with it's 51% controlling interest in GLE and then allow another company to build the Wilming plant on THEIR land, it won't happen in my opinion, I think what may be happening is that Hitachi may be parting with teir 25% because I believe they now have other fish to fry.<br /><br />If wilmington is going ahead then so is Paducah, because part of what they get there (the u235 in the form of UF6 and also the U238 as a future fuel for fast breeder reactors) is a necessary component of the re enrichment of RepU from the Used Nuclear Fuel, all of this is associated with PRISM and the Advanced Recycling Center, the ARC separates out three bundles, one is the Plutonium and some actinides mixed in, the second is what they call the Candu bundle, because it can be used directly in a Candu reactor but only once more, or they can re enrich it back to LEU grade and re use it back in a light boiling water reactor and they can do this many times over, besides nthe US doesn't have any Candu reactors.<br /><br />I will post more on this later.
  4. It,s been a long time since I posted here, this is something that I posted on Hotcopper, maybe some of you are interested as someone from here was asking me? There is more to this but I won't be posting it here, but if I know you I will share it, so long as it isn't revealed here or anywhere else! Paducah and Wilmington are both going ahead NEXT YEAR, Q2 of 2017 is when the estimated start is occurring. Paducah is an integral part of the Wilmington plant, it is required to provide top up fuel in the form of UF6 to enable recycling of UNF. Paducah is a dual purpose plant also just like I predicted, they are going to build a purpose built storage area for the recovered U238, something that Michael Goldsworthy said is valuable in his address to the SA royal commission, it will be used as part of the fuel for next generation IV reactors, I have always said the plant had to be serving more than one purpose and it is, I also said that they would not be selling the Uranium on market and it looks to me as if they are not, they will lease it to GLE for recycling, I won't post the second link about PPaducah, it may possibly be harmful to Silex, for non disclosure reasons? Early this year I found the link below , I was excited about that, but I decided to look further. I first of all found this link -: http://www.construction-ic.com/HomePage/Pr...rview%2F151013# GLE – Laser Uranium Enrichment Plant – North Carolina Project Overview Project Stage: Planning Profile Status: Live Project Type: Parent Project Announcement Quarter: Q1 2009 Project Value: USD 1000 million Construction Start Quarter: Q3 2016(Estimated) Project City: Wilmington Project End Quarter: Q4 2020 Construction Type: New Project Country: United States Location Type: OnShore Last Update: 9 Dec 2015 Funding Mode: Private Project Description Global Laser Enrichment (GLE), a joint venture between General Electric Co., Hitachi Ltd and Cameco is planning to construct the Laser Uranium Enrichment Plant project in North Carolina, the US. The project involves construction of a laser uranium enrichment facility. The project includes the construction of production units, storage tanks and other related facilities and the installation of machinery and safety systems. Silex Systems Ltd (Silex) has been appointed to provide laser technology for the project. In June 2009, GE-Hitachi (GEH) submitted the last part of its license application for the GLE plant. In third quarter of 2009, GLE began a 'test loop' for the commercial use of the laser enrichment process. In April 2010, GLE announced successful completion of the first phase of the test loop program, designs for the commercial facility were evolved and economic feasibility was verified. In February 2012, Nuclear Regulatory Commission (NRC) published a favorable environmental review of the project. The US Nuclear Regulatory Commission (NRC) has issued a license for development of the project in September 2012. In May 2013, further tests are being conducted to accumulate performance, operating reliability and life-time data on the technology. Planning activities are underway. Stakeholder Information: Planning Authority: US Nuclear Regulatory Commission Consultant Contract (Technology): Silex Systems Limited You will note that if you open the above link now the info has been updated, it is for a 1MWSU pilot plant in my opinion. to test recycling of UNF. Finding this link above made me think! hey I wonder if they also had something on Paducah? So I tried a few tags from the Wilmington one but changed the name to Paducah ! Maybe you can find it yourself if you look hard enough? For those that don't believe GLE are preparing a pilot plant for UNF recycling? just read this link it has lots of useful info in it, some of which I have posted here. The Russians are in the UNF recycling race already, I posted a link about that previously, and guess what? they will alos be adding U235 into the recycled UNF to bring it back up to specs as LEU and the Russians are also going to lease the Uranium in the recycled UNF. http://www.nrc.gov/materials/reprocessing.html#repro Background In 2007, the Commission directed the staff to complete an analysis of Title 10 of the Code of Federal Regulations (10 CFR) to identify regulatory gaps for licensing an advanced reprocessing facility and recycling reactor. In mid-2008, two nuclear industry companies informed the agency of their intent to seek a license for a reprocessing facility in the U.S. An additional company expressed its support for updating the regulatory framework for reprocessing, but stopped short of stating its intent to seek a license for such a facility. At the time, the staff also noted that progress on some Global Nuclear Energy Partnership (GNEP) initiatives had waned and it appeared appropriate to shift the focus of the staff's efforts from specific GNEP-facility regulations to a more broadly applicable framework for commercial reprocessing facilities. I have documents that show that the two companies that approached the NRC were AREVA and GLE.
  5. Several weeks ago now I received an email from someone called service @ support dot com dot au they asked me to update my paypal records, they even had the paypal logo, alarm bells rang, so I called Paypaql and spoke to them asking if they had sent something like that? the answer was no, the person at Paypal said they always address you by your full name whereas in this email they just said Dear Customer , so don't be fooled, it is a scam, more than likely they have your ebay info and are trying to marry up the paypal info. Cheers Moosey
  6. http://www.heraldsun.com.au/business/break...o-1226641319565 Samsung announces 5G data breakthrough From: AAP May 13, 2013 3:25PMSAMSUNG Electronics says it has successfully tested super-fast fifth-generation (5G) wireless technology that will eventually allow users to download an entire movie in one second.The South Korean giant says the test has witnessed data transmission of more than one gigabyte per second over a distance of two kilometres. The new technology, which will not be ready for the commercial market before 2020 at the earliest, will offer transmitting speeds "up to several hundred times faster" than existing 4G networks, it said in a statement on Monday. That will permit users to "transmit massive data files including high quality digital movies practically without limitation", it said. "As a result, subscribers will be able to enjoy a wide range of services such as 3D movies and games, real-time streaming of ultra high-definition (UHD) content, and remote medical services," it added. Samsung said it had found a way to harness millimetre-wave bands which have proved to be a sticking point for the mobile industry to date. The test used 64 antenna elements, which the tech titan said overcame the issue of "unfavourable propagation characteristics" that have prevented data travelling across long distances using the bands. One of the most wired countries on earth, South Korea already has around 20 million 4G users.

    What's up? SP doing very well today?
  8. After the latest release, I emailed Dr Kelly and spoke to him about some concerns I had with the setting up of Novogen North America, especially after seeing what had happened with Marshall Edwards, he did answer me very promptly and said it was a good question and it gave him the opportunity to explain a few things in the blog, I again emailed him and thanked him and apologised to him for the prickly question, he told me it wasn't a prickly question and he understood completely where I was coming from. here is what Dr Kelly placed on the Novogen website blog. Following question from shareholder ‘Moosey’. The announcement on the 18th April 2013 was great, my only concern was the setting up of Novogen (North America) Inc. I would like an undertaking by Dr Kelly that the company remains an Aussie company and any IP found belongs to the parent, one that doesn’t end up resembling something like MarshallEdwards did. I understand why Novogen would like an American presence, that is where the money is and that is also close to some of the most important cancer research centers, but I have seen other companies who did something similar, the old Novogen being a case in point and then see the American offshoot end up either taking over completely or causing the parent in Oz to fail and then they pick up all the pieces for bugger all and shareholders in Oz end up with stuff all, but in the old Novogen’s case though at least we did end up with shares in MEIP. Like I said I don’t mind an American presence so long as it stays just that, a presence, one where the intent is that the parent Novogen remains in full control and always will unless it is sold. I would love for this great technology to stay here in Australia if possible? Can we have that in writing Dr Kelly? Dear Moosey, One big difference between the MEIPharma Inc situation and the Novogen (North America) Inc. MEI was set up to house oncology drug development. It was always intended to be an independent company, which it eventually became 10 years later. And as you point out, Novogen shareholders have retained their investment in that company which we all hope will deliver a pay-off in due course. The only part of the plan that didn’t work out was that the rest of Novogen was meant to go on to bigger and better things, which for various reasons didn’t happen. In a way I am glad that part of the plan didn’t work out, because it has given 3 ex-Novogen scientists the chance to come back in and take Novogen to a level which we believe will be well beyond anything we ever dreamed of before. Novogen (North America) Inc is not a drug development company. It owns no IP and conducts no R&D and has no intention of ever doing so. It is purely and simply an administrative arm of the parent company. I wanted a presence in North America. We might be an Australian-based company, but two-thirds of our shares are held as ADRs and to the best of our knowledge, our current 3,900 Australian shareholders are about half the number of US shareholders. That situation warrants and deserves a local presence. Also, increasingly we will be conducting more and more of our R&D in the US and Europe. Plus we have made a substantial commitment to having all our manufacturing conducted in Switzerland which Andrew Heaton is overseeing. Plus he is responsible for our patent portfolio and for the lodgement of an IND with the FDA. It just makes sense to have someone closer to that action and able to respond to issues in real time. The challenges of basing an Australia resident in the US on an open-ended basis meant that we needed to have that person employed by a US company. That is the genesis of Novogen (North America) Inc. The Novogen technology will stay in Novogen. You want it in writing? ….. OK. It will leave Novogen Ltd over my dead body. But let’s not get too precious about this country thing. The Company’s primary listing might be Australia…. but we are for all intents and purposes a US company as it currently stands in terms of ownership. Graham Kelly
  9. A poster who calls himself Toby10 posted this on HC, I don't think he posts here or hasn't for some time so I will repost it here with credit to him. I post it because it shows that the Uranium Enrichment Plant/s appear to be going ahead with possibly not one plant but two and maybe more in the future? It also seems clear to me that they intend to use the laser system for enriching Uranium for more than just reprocessing tails or normal new UF6 which comes from the mines and is then treated to become UF6, I believe that this new advancement they are talking of is for special nuclear fuel from the Advanced Recycling Centre that GE talks about.

  10. CS-6 is basically an extension of a platform that came from other older compounds already in trials with MEIP and also owned by them now, I really don't see any problems with safety first of all, but also with the drug in general because of the path it has taken to where it is now, I just hope they don't try and change the delivery systems whilst in trials, at least not this time around. It is also worth remembering that CS-6 when it was first tested in the US, was when it had both the left AND right handed forms combined which are known as enantiomers,In manufacturing terms, CS-6 is classified as a chiral molecule, meaning that the molecule can exist in both left and right hand forms known as enantiomers. usually one of these entantiomers is much stronger than the other, so the result in that those tests would have been much lower than would have been the case if they had used only the better side of CS-6, but even then they were fantastic, they say this new form is 200 times better, that has to be good for dosage requirements etc, I remember years ago when they were talking about some of the earlier drugs from the earlier platforms, would lead to chemotherapy where only a very small amount of the drug was required, which in turn led to no hair loss or many of the horrific side effects experienced by cancer sufferers when undergoing chemotherapy. "Novogen Chief Scientific Officer, Dr Andrew Heaton, today said, “The ability to manufacture CS-6 in both left and right hand forms represents a significant milestone in the development of this compound. The indication that one form of CS-6 is active at "nano molar concentrations" against a broad spectrum of brain cancer lines is exciting and indicates that the earlier potencies we have seen against cancer cells and cancer stem cells are likely to be even greater with the purified enantiomer. "We are now positioned to rapidly progress CS-6 to the clinic.†This is the definition of nanomolar from wordnik-: “Scientists have for decades been doing experiments using chemi­cals in ­nanomolar quanti­ties, which simply means that they're ­extraordinarily dilute.†http://www.wordnik.com/words/nanomolar So that means bugger all active is required, which is good for profits and I also have read that it is comparatively easy to manufacture in quantity using a new method also developed by Novogen/Triaxial. Hopefully one day this cancer cure may mean that it would be equivalent to not much more than having a flu injection or two?
  11. WHY I'M DEPRESSED Over five thousand years ago, Moses said to the Children of Israel, "Pick up your shovels, mount your asses and camels, and I will lead you to the Promised Land." Forty years ago Whitlam said "Lay down your shovels, sit on your asses, and light up a Camel, this IS the Promised Land." Today Julia Gillard has stolen our shovel, taxed our asses, put camels in plain packaging and mortgaged the Promised Land! Last night I was so depressed thinking about all this. The Health Care Plans, the Carbon Tax, the Slow Economy, the Wars, the Lost Jobs, Savings, Interest Rates, Social Security and Retirement Funds, so I called a Suicide Hotline. I had to press 1 for English, and I was then connected to a call center in Pakistan . I told them I was suicidal. They got all excited and asked if I could drive a truck....
  12. I hasn't held it's price YET simply because this was basically just a repeat of the first release in a fashion, saying that the results were confirmed in a second test, there is more news coming soon, I think that by years end the SP will be much higher if all goes to plan.
  13. It's nice to see Josiah T Austin is still on the board of the new Novogen as Non-Executive Director, that surely means that he hasn't sold his shares one would think? Mr Austin was appointed to the Novogen Board on 20 September, 2010. He is the managing member of El Coronado Holdings, LLC, a privately owned investment holding company, which invests in public and private companies. He and his family own and operate agricultural properties in the states of Arizona, Montana, and northern Sonora, Mexico through El Coronado Ranch & Cattle Company, LLC and other entities. Mr Austin previously served on the Board of Directors of Monterey Bay Bancorp of Watsonville, California, and is a prior board member of New York Bancorp, Inc., and North Fork Bancorporation. He became a director of Goodrich Petroleum, Inc., in 2002. Mr Austin also serves as a trustee of the Cuenca Los Ojos Foundation Trust, a non-profit organisation working to preserve and restore the biodiversity of the borderland region between the United States and Mexico through land protection, habitat restoration and wildlife reintroduction.

  15. UCLA researchers develop new technique to scale up production of graphene micro-supercapacitors By Davin Malasarn February 19, 2013 http://newsroom.ucla.edu/portal/ucla/artwork/4/3/5/5/3/243553/Micro-supercapacitor-c.jpg Kaner and El-Kady's micro-supercapacitors While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors. Now, Richard Kaner, a member of the California NanoSystems Institute at UCLA and a professor of chemistry and biochemistry, and Maher El-Kady, a graduate student in Kaner's laboratory, may have changed the game. The UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors  devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom–thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers. The new cost-effective fabrication method, described in a study published this week in the journal Nature Communications, holds promise for the mass production of these supercapacitors, which have the potential to transform electronics and other fields. "The integration of energy-storage units with electronic circuits is challenging and often limits the miniaturization of the entire system," said Kaner, who is also a professor of materials science and engineering at UCLA's Henry Samueli School of Engineering and Applied Science. "This is because the necessary energy-storage components scale down poorly in size and are not well suited to the planar geometries of most integrated fabrication processes." "Traditional methods for the fabrication of micro-supercapacitors involve labor-intensive lithographic techniques that have proven difficult for building cost-effective devices, thus limiting their commercial application," El-Kady said. "Instead, we used a consumer-grade LightScribe DVD burner to produce graphene micro-supercapacitors over large areas at a fraction of the cost of traditional devices. Using this technique, we have been able to produce more than 100 micro-supercapacitors on a single disc in less than 30 minutes, using inexpensive materials." The process of miniaturization often relies on flattening technology, making devices thinner and more like a geometric plane that has only two dimensions. In developing their new micro-supercapacitor, Kaner and El-Kady used a two-dimensional sheet of carbon, known as graphene, which only has the thickness of a single atom in the third dimension. Kaner and El-Kady took advantage of a new structural design during the fabrication. For any supercapacitor to be effective, two separated electrodes have to be positioned so that the available surface area between them is maximized. This allows the supercapacitor to store a greater charge. A previous design stacked the layers of graphene serving as electrodes, like the slices of bread on a sandwich. While this design was functional, however, it was not compatible with integrated circuits. In their new design, the researchers placed the electrodes side by side using an interdigitated pattern, akin to interwoven fingers. This helped to maximize the accessible surface area available for each of the two electrodes while also reducing the path over which ions in the electrolyte would need to diffuse. As a result, the new supercapacitors have more charge capacity and rate capability than their stacked counterparts. Interestingly, the researchers found that by placing more electrodes per unit area, they boosted the micro-supercapacitor's ability to store even more charge. Kaner and El-Kady were able to fabricate these intricate supercapacitors using an affordable and scalable technique that they had developed earlier. They glued a layer of plastic onto the surface of a DVD and then coated the plastic with a layer of graphite oxide. Then, they simply inserted the coated disc into a commercially available LightScribe optical drive  traditionally used to label DVDs  and took advantage of the drive's own laser to create the interdigitated pattern. The laser scribing is so precise that none of the "interwoven fingers" touch each other, which would short-circuit the supercapacitor. "To label discs using LightScribe, the surface of the disc is coated with a reactive dye that changes color on exposure to the laser light. Instead of printing on this specialized coating, our approach is to coat the disc with a film of graphite oxide, which then can be directly printed on," Kaner said. "We previously found an unusual photo-thermal effect in which graphite oxide absorbs the laser light and is converted into graphene in a similar fashion to the commercial LightScribe process. With the precision of the laser, the drive renders the computer-designed pattern onto the graphite oxide film to produce the desired graphene circuits." "The process is straightforward, cost-effective and can be done at home," El-Kady said. "One only needs a DVD burner and graphite oxide dispersion in water, which is commercially available at a moderate cost." The new micro-supercapacitors are also highly bendable and twistable, making them potentially useful as energy-storage devices in flexible electronics like roll-up displays and TVs, e-paper, and even wearable electronics. The researchers showed the utility of their new laser-scribed graphene micro-supercapacitor in an all-solid form, which would enable any new device incorporating them to be more easily shaped and flexible. The micro-supercapacitors can also be fabricated directly on a chip using the same technique, making them highly useful for integration into micro-electromechanical systems (MEMS) or complementary metal-oxide-semiconductors (CMOS). These micro-supercapacitors show excellent cycling stability, an important advantage over micro-batteries, which have shorter lifespans and which could pose a major problem when embedded in permanent structures  such as biomedical implants, active radio-frequency identification tags and embedded micro-sensors  for which no maintenance or replacement is possible. As they can be directly integrated on-chip, these micro-supercapacitors may help to better extract energy from solar, mechanical and thermal sources and thus make more efficient self-powered systems. They could also be fabricated on the backside of solar cells in both portable devices and rooftop installations to store power generated during the day for use after sundown, helping to provide electricity around the clock when connection to the grid is not possible. "We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors," Kaner said. http://newsroom.ucla.edu/portal/ucla/ucla-...que-243553.aspx
