Thermal Curtains Are Conventional Looking Window Coverings That Save Energy

Friday, September 28th, 2007 by MICE Editor

If you are living in a colder climate, it makes you recognize how important thermal
curtains can be used for insulating a house. A cost efficient option, to most additional
heating solutions, curtains are a fairly nominal one-time deal. They can keep your
house comfortable and warm all through the cruel winter months without sending your
heating bill through the top.

Thermal curtains are in the middle of the more useful tools for keeping a home warm.
Additional five times as efficient at insulating compared to a traditional curtain, they
use thermodynamics to keep heat in. Windows are a main source of heat loss, since the
panes conduct high-energy heat away from the home and in the direction of the low
energy area of the outside.

This difficulty is enhanced, by weakening frames and window casings that allow
pockets of cold air to leak in. Thermal curtain uses insulating fabric to create a fence
intended to block this procedure. They can be made from scratch, but these days, it is
just as simple to buy them online. The simplicity of the Internet makes it useful to look
for professional-grade goods that will actually do the trick throughout the most
horrible months of winter.

A Sustainable Alternative – Conventional vs Straw Bale Construction

Saturday, September 22nd, 2007 by MICE Editor

Embodied energy is the energy required to extract, transport, process, install, and dispose of, or recycle the materials that make up the building.

For this study, the total embodied energy was not used to compare the two construction types, only the energy for the material manufacture was used, because energies used to transport, install etc. would in most instances be the same for both construction types and cancel each other out, and because almost 70% of the total energy invested in a building’s construction (Embodied energy) is embodied in the materials themselves, one can compile a rather accurate comparison with using just the energy used for the material manufacture alone, however, when referred to the energy used to manufacture the materials I will refer to the “Embodied energy”.
Materials which will be more or less the same in quantity / volume eg. ceiling boards, cornices, skirtings, floor slab & finishes, because of the same floor area, have been omitted for they will have no impact on the embodied energy outcome.

Construction
To compare the two types of construction, I started with a 12000mm x 6000mm brick building and included 2 bedrooms, a bathroom, open plan kitchen & living and a garage. To justify the comparison, I designed the strawbale dwelling with the same rooms and exactly the same floor area for each room, but because of the bales’ rather wide (approx. 480mm) module width I ended up with a 13200mm x 7250mm external envelope for the straw bale dwelling. This made quite a difference on the material volume of the roof and roof trusses. Both the dwellings’ received one plaster coat, but vary in thickness. Conventional brick wall plaster width vary from apprx. 12mm – 18mm, compared to the 30mm plaster coat for strawbale walls because of the greater surface un-evenness among other reasons.

The foundation details differs from conventional brick buildings. The straw bales are laid on a bed of stone so they will not retain moisture. A cement screed is cast in the bottom of the trenches on the conc. footing to be sure that any water that might find its way into the trench would be directed away through the weep holes on the sides. These are the only bricks used in the strawbale dwelling, thus embodied energy values for mortar and bricks are a lot less for this type of construction. The foundations for strawbale buildings are shallower (200mm deep), thus less conc. Is used as well.

The last main difference is, of course, the wall material which differs hugely in the amount of embodied energy to produce & install them. Embodied energy for straw bales is 31MJ/m3 compared to the 5200MJ/m3 of stock bricks, thus because the walls have the greatest material volume of all the building components, it is understandable that the strawbale dwelling will have a much lower total embodied energy value than it’s rival as is indicated below.

Conclusion
Straw is a viable building alternative, plentiful and inexpensive. Straw-bale buildings boast super-insulated walls simple construction, low costs, and the conversion of an agricultural byproduct into a valued building material. Properly constructed and maintained, the straw-bale walls, plaster exterior and interior remain water proof, fire resistant, and pest free. Because only limited skill is required, a community house-raising effort can build most of a straw-bale house in a single day. This effort yields a low-cost, elegant, and energy-efficient living space for the owners, a graceful addition to the community, and a desirable boost to local farm income. I think, especially in this country, residential straw bale buildings could be a very sustainable viable alternative to residential architecture.

Conventional Mining Will Keep Uranium Price High

Tuesday, September 18th, 2007 by MICE Editor

“I never thought I would say this,” announced Dustin Garrow, marketing director for Paladin Resources (TSX: PDN) at the close of his presentation to an audience comprised of utility and nuclear fuel insiders. Then, he forecast a rise in the price of uranium in the coming months to between $80 and $100 per pound. A long-time industry consultant, Garrow acts as an intermediary between uranium producers and utility fuel brokers.

The Platts Nuclear Fuel Strategies conference held this past week in Washington, D.C. was sobering for U.S. utilities, yet revitalizing for the assorted suppliers and vendors attending this educational workshop. The jump in the spot uranium price to $55.75/pound, over the weekend, was hardly a surprise for those who participated. The conference’s mood was buoyant and electrifying as steady demand continues to strengthen for the ‘active supply’ of uranium. Analysts may be forced to upwardly revise their price expectations going forward through the end of this year and for 2007.

TradeTech published on the company’s website commentary on uranium transactions, writing, “Many sellers continue to seek market-related pricing terms for spot delivery and buyers continue to show a willingness to raise bid prices in order to secure supply at fixed prices. The buyer mix remains diverse, with utilities, producers, intermediaries, and speculators seeking market purchases. Long-term uranium demand remains strong and continues to exert upward pressure on the spot uranium price. The spot uranium market is expected to remain active through October.”

We talked further with Gene Clark, Chief Executive of TradeTech, by email after briefly chatting at the Platts conference. He added his company was tweaking assumptions on price projections for utilities in a soon-to-be-published uranium market study. “We expect prices in the fourth quarter to continue to significantly exceed all previous expectations,” Clark wrote to us. “Active supply, which is our measure, determined by telephone interview of uranium actually being offered in the market, is back to the level of its historical low in the second quarter of 2004.” Earlier this year, Clark forecast spot uranium would reach $55/pound.

Clark considers this a major factor for uranium price forecasting. “Many potential sellers of uranium are holding back supply, making it ‘inactive,’ because they are satisfied with their level of sales for this year,” he explained. “Barring the entry of a major new source, active supply is expected to remain low for the rest of the year.” The major source of demand, through the end of the year is likely to come from traders and hedge funds, Clark informed us. He lowered the demand status of primary users such as utilities from the ‘must have’ category to discretionary buying.

World Uranium Mining Trends and Outlook

“We’ve been trying to encourage utility companies to work more closely with junior uranium companies,” announced Michael Knapik, Chief Editor of Platts’ NuclearFuel, before the uranium mining panel began their presentations. In a previous presentation that morning, Charles Peterson, a partner with the DC-based law firm Pillsbury Winthrop Shaw Pittman LLP had talked about the security of future uranium supply. Utilities have been hooked on buying low-cost uranium from Canada, Australia and Kazakhstan. Peterson has been advising utilities to begin discussions with speculators who have been purchasing uranium as the price has soared. “Some utilities are cooperating with speculators,” Peterson observed.

As we reported at the conference last week, Scotiabank’s vice president of economics Patricia Mohr believes uranium will continue to be a bright spot in the commodities market in 2007. She pointed out her bank’s commodity index had probably peaked in August, but she felt uranium would be the “exception to this.” Mohr cited inadequate mining supply as the primary driver in the spectacular rise in the uranium price. Uranium producers only contributed 65 percent to last year’s demand, while the balance came from inventory sales and blended down uranium from decommissioned Russian warheads.

Paladin and Namibia

Dustin Garrow talked about Paladin’s amazing success story, discussing how he was approached by the company’s CEO in 2003 when the stock was trading for three cents and offered stock options. Three years later, Garrow remains ebullient on Paladin’s growth prospects in Africa and elsewhere. It is a tribute to unrestrictive environmental regulations in Namibia and Paladin’s rapid execution at the Langer Heinrich uranium project that the company can announce it will be shipping its first yellowcake in early 2007.

In an interesting disclosure, Garrow explained how Paladin had arranged a syndicated loan agreement to fund its mine development and construction. Clauses within this loan agreement required the mandatory forward sale of a portion of the mine’s production. Those two sales contracts of more than 5 million pounds of U3O8 are scheduled for delivery between 2007 and 2012 to two U.S. utilities. Garrow led the audience to believe selling at such a low price was not something Paladin desired. Arranging the sale with his partner, Garrow said, “My partner and I have a combined 50 years in this business, and we provided this uranium to our most preferred customers.”

Currently producing about seven percent of the world’s uranium, Namibia has become a hotspot since we reported on this country last March. At the time, there were but three companies. Since then, the number has grown to 14, according to an announcement by the Ministry of Mines and Energy. We checked the progress on Forsys Metals (TSX: FSY), which we reported upon in March. Forsys spokesman Sean Felker told us, “We are revising our resource calculation and releasing it in the fourth quarter.” The company has spent this year further proving up their resource, while the company’s stock continues flying under the industry’s radar screen.

A research report by Orion Securities in Toronto, which participated in raising money for Forsys, suggested the all-in cost to mine the company’s Valencia project could come in under $25/pound and would have an IIR of 30 percent after tax. Early estimates show the Valencia project might annually produce 2.5 million pounds of U308 over ten years. This was sufficient to interest the fuel broker for a major U.S. utility. Felker said, “We’ve started the process of marketing our uranium after the utility sent a consulting geologist to study the property.” Due diligence was done on site in Namibia. Felker explained his company’s Valencia project was about 30 months away from where Paladin’s Langer Heinrich is today.

Forsys appears to be following Paladin’s lead. As success was developing for Paladin in Namibia, the company moved to near completion of a bankable feasibility study at the Kayelekera uranium project in Malawi. Now, Forsys is considering other uranium properties in Africa. Both companies, and others developing uranium projects in Africa, will utilize the open pit method to maximize recovery of uranium from their mines.

David Miller Predicts More U.S. Uranium
Will be Conventionally Mined

It is likely that rising uranium prices will beget more costly uranium extraction methods, which of course will provide a more solid floor for the uranium price over the next ten to fifteen years.

The presentation made by Strathmore Mineral’s President David Miller vividly illustrated why the United States can continue mining uranium over the next two decades. Admittedly, the United States is unlikely to return to the glory uranium production years of the 1950s and 1960s. “The U.S. can still become a medium size uranium producer,” Miller told the audience. He predicted conventional mining would replace the preferred method of ISR mining in the United States in less than ten years. In Miller’s presentation, he forecast conventional uranium mining – through underground and open pit mining methods – might exceed 16 million pounds annually by 2020.

Miller’s research demonstrated a number of uranium companies whose combined annual production could reach nearly 30 million pounds by 2020. In several slides, he extrapolated production estimates from various companies – such as Uranerz Energy (Amex: URZ), UR-Energy (TSX: URE), Energy Metals (TSX: EMC) and Strathmore Minerals (TSX: STM) – to reach annual uranium production in excess of ten million pounds after 2012.

Miller explained to the audience that U.S. production could surpass 20 million pounds later in the second decade and help provide U.S. utilities with more than one-quarter of their annual consumption. He has argued, along with the Uranium Producers of America, for the development of a domestic uranium supply to benefit U.S. utilities from over-dependence upon foreign uranium.

We talked with him after his presentation about time frames and the mine operating costs at various uranium grades. Miller told us, “It will take the U.S. about four to six years to get up to steam.” A lot of the hurdles to overcome were not the mining issues or fund raising to bring those projects into production. “There are a number of interested parties wishing to participate in different U.S. uranium projects,” he told us without naming anyone in particular. “It is the permitting time which takes so long.”

He calculated, from studies he was recently involved with, that the operating costs for an underground mining and milling operation would cost about $80 to $120/ton. An average grade of 0.1 percent U3O8 would yield two pounds per ton, but a feed grade averaging 0.2 percent would yield four pounds per ton. Uranium ore yielding four pounds per ton would cost about $25/pound. Miller explained that grades at Green Mountain, which SXR Uranium One is currently investigating for purchase, and his company’s Roca Honda property, should be profitable using the $100/ton benchmark. Both properties have reported economic grades through various studies.

Strathmore’s Roca Honda property in New Mexico demonstrated its resource through a National Instrument 43-101. Miller emphasized the higher percentage of recovery in New Mexico. “Historically, the Grants Uranium District in New Mexico recovered mid 90s percent,” he told us. “You don’t produce mine 340 million pounds (historical production in this area) by having poor recovery.” By comparison, Miller said the recovery rate in Wyoming was in the low 90s percentage-wise. These percentages exceed conventional mining average recovery rates as stated in the IAEA Red Book.

In evaluating production costs, derived from discussions with other industry insiders, it is likely the resurgence of conventional mining could potentially double the capital and operating costs of several uranium projects. While it is possible some or several ISR uranium projects in Wyoming, Texas or New Mexico could enjoy operating costs for less than $30/pound, the capital cost for an underground U.S. uranium mine and mill could reach $200 million.

Rising labor costs, environmental regulations, increased start-up costs and even weather-related occurrences, such as the cyclone impacting production at Australia’s Ranger uranium mine, point to a continued rise in the price of uranium over the next few years. At the very least, utilities might be facing a new floor price should the overheated uranium market step back a few price levels over the coming year or years.

In the next feature in this series, further conversations we had at the Platts conference confirm Gene Clark’s comments, and those made by others, that the uranium price has exceeded nearly everyone’s expectations. And it should continue doing so in the months ahead. To be continued.

Attending a Convention or Trade Show in Denver Here’s Helpful Information

Tuesday, September 18th, 2007 by MICE Editor

If you’re attending a convention or trade show in Denver, and you’re a stranger to town, here is information that can make your visit here more enjoyable.

1.DIA (Denver International Airport). When you arrive at DIA, you will walk down your concourse to a center area. This is where you will find steps down to the trains that connect our concourses to the main (Jeppesen) terminal. When you reach the terminal, you’ll get off your train and walk up two flights to the main level, which is actually called Level 5. This is where you will pick p your luggage. If you are renting a car, you will find the major car rental companies are also on Level 5.

2.Catch a taxi to the downtown area. Denver’s largest taxicab companies are Yellow Cab (303) 777-7777) and Metro Taxi (303-333-3333). Be aware that a cab ride to downtown Denver isn’t cheap. Yellow Cab charges $43.00 plus a $3.25 gate fee, plus $1.00 for every passenger beyond the first. You can pick up a cab on Level 5 (where you got your luggage), Island 1.

3.Save money. Take a shuttle downtown. A less expensive alternative to taxis is to take a shuttle. My choice would be Super Shuttle (800-525-3177). It offers service to just about any hotel in the metro area and its fares are reasonable.

4.When you need copies or printing services. Just about every downtown Denver hotel has a business center where you can get copies made or other business-type services. But not all of these are open 24/7. So, if it’s 11:00 pm and you need 200 copies of a brochure pronto, you can go to Fed Ex Kinkos at 1509 Blake St.

5.The Colorado Convention Center. The Convention Center is located at 700 14th St. (between Stout and California on 14th St. It has onsite parking (daily event rate = $7.00) , wireless Internet access and excellent food and beverage service. If you are lucky enough to be staying at the new Hyatt Regency Convention Center, you will be literally across the street from the Convention Center. All downtown hotels are relatively close to the Center but the to closest are the Denver Marriot City Center at 1701 California St. and the Hyatt Regency at 650 15th Street. You can get more information on the Colorado Convention Center by going to http://www.denverconvention.com/center.asp
