10 Amazing Homes-Local Festus MO Home Included #4

10 Amazing Homes You Won't Find In Your Neighborhood

By Diane Tuman, Content Manager , Zillow.com
Sep 9, 2010

If you consider yourself a non-conformist, or one who shuns traditional ways of doing things, then here is a perfect lineup of nontraditional homes that should fit your spirit perfectly. Take your pick from a church, an old firehouse, an earthship home, a geodesic home, a floating home, and even a decommissioned missile site. Plus, some of these homes are for sale!

Old Firehouse - 117 Broad St, San Francisco, CA
Old Firehouse

1. Old Firehouse - 117 Broad St, San Francisco, CA 94112
Status: For Sale - $975,000

San Francisco's Firehouse 33 was in the business of fighting fires from 1896 to 1974. Up until 1921, it had two horses, a steamer, a Dalmatian and a rotating crew of firefighters. When bigger fire engines were built in the 1970s, Firehouse 33's doors could not accommodate the wider girth and so, the original Firehouse 33 became obsolete and a new Firehouse 33 was built around the corner. An entrepreneurial couple bought this firehouse and turned it into a home/business - the "San Francisco Fire Engine Tours & Adventures" business. It has two beds, two baths and 4,000 sq ft of space, plus interesting amenities such as the original redwood lockers the firemen used, lots of closet space, a garage that can fit six cars (and a firetruck, if you had one) and of course, a fire pole!

Old Church, 601 Dolores St, San Francisco, CA
Old Church

2. Old Church - 601 Dolores St, San Francisco, CA 94110
Status: For Sale - $7,490,000

Yes, here we are in San Francisco again (surprised?) where we find a fabulously restored Gothic Revival home that was formerly a church. At 17,000 sq ft, it is said to be one of the largest single family homes in San Francisco. The living room features a soaring, coffered, hand-painted ceiling with seven enormous chandeliers, stained glass windows (naturally) and arched windows looking out to Dolores Park. Climb to the tower meditation room and deck for a 360-degree view of the city.

Round House- 122 Olmstead Hill Rd, Wilton, CT
Round House

3. Round House- 122 Olmstead Hill Rd, Wilton, CT 06897
Status: Presently off the market

Known as the "Connecticut Round House," this unique property has been listed for sale a couple times before being recently removed with a list price of $1,750,000 (it was listed in 2008 for $2.3 million). Designed by architect Richard T. Foster, it is a cylindrical masterpiece that sits 12 feet off the ground on its "base" and has the ability to rotate slowly 360 degrees, taking in the nearly four acres of land and a pond. It takes about 50 minutes to complete an entire rotation and can be stopped, slowed down or speeded up. Made of steel, glass and shingles, the 3,000 sq ft home was renovated in 2005 and is completely walled in glass. It features custom ash cabinetry, state-of-the-art Xenon interior lighting, marble and limestone bath finishes, and "Smart House" technology in the main house." Plus, there is a separate guest house and in-ground lap pool.

4. Cave house - 1101 N 11th St, Festus, MO 63028
Status: Presently off the market

The "Cave House" was on the market in a distress sale in 2009, but it appears the owners were able to re-work their adjustable-rate loan and have now happily settled back into cave life. The 17,000 square foot house - er, cave - is in Festus, MO, and has three chambers: a front chamber that contains three bedrooms; a middle chamber that holds the laundry room, storage, and a spare bath, and the back chamber that still has the stage where Ted Nugent, Bob Seger, Ike and Tina Turner, and many other entertainers performed. Obviously, the owners of this cave are very well connected. No furnace or air-conditioning needed; geothermal and passive solar systems keep the home comfortable year-round.

Earthship - 6 High Meadow Dr,Taos, NM
Earthship

5. Earthship - 6 High Meadow Dr, Taos, NM 87571
Status: For Sale - $265,000

That's right - you won't find this "earthship" in a well-manicured cul-de-sac in most regions of the U.S., but your chances are much greater in New Mexico or Arizona. Called "Sol Ship," this one-bed, one-bath earthship is designed for off-the-grid living and uses passive solar thermomass construction that heats and cools the interior. But don't worry - you can tap into traditional systems if you have a craving for microwave popcorn. Many earthships are a little rough around the edges with recycled materials visibly poking out (tires, cans, bottles) but this is a higher-end earthship with an indoor koi pond and hand-plastered walls with whimsical sculpted displays around the fireplace and walls. Two underground, 3,000-gallon cisterns hold water. Own this home and no one will insult you about your carbon footprint, because it doesn't exist.

Geodesic home -  2643 Birch Ave, Batavia, IA
Geodesic home

6. Geodesic home - 2643 Birch Ave, Batavia, IA 52533
Status: No longer on the market

Geodesic dome homes rode a wave of popularity in the 1960s and 70s, but their construction is now limited due to challenges in code requirements. While the exterior is round, the interior of geodesic homes contain many angles - just try to find a wall in which to hang a photo, or a long flat wall to position the couch. This four-bed, 3.5-bath dome home sits on 20 acres.

t
Floating home

7. Floating home - 2466 Westlake Ave N, Seattle, WA 98109
Status: For Sale - $975,000

No, Tom Hanks does not live here and this is not the Sleepless in Seattle floating home, but this is a quintessential floating home on Seattle's Lake Union and better yet - it's never been lived in. The shingled-style master craftsman design offers two bedrooms and one bath.

Old Barn - 9424 Windsong Loop NE, Bainbridge Island, WA 98110
Old barn

8. Old Barn - 9424 Windsong Loop NE, Bainbridge Island, WA 98110
Status: Recently sold - $542,000

This Bainbridge Island, WA barn was built 104 years ago and was used as a dairy farm before being converted into a home. It retains its barn shape with soaring, cathedral ceilings with exposed beams and rough-hewn floors. Rolling barn doors serve as shutters to two bedrooms and one original wall reveals the original penciled shopping list that includes 2,100 pounds of seeds. Sixteen windows in the open living area draw passive solar heat and natural light.

Shoe House - 197 Shoe House Rd, Hellam, PA

9. Shoe House - 197 Shoe House Rd, Hellam, PA 17406
Status: Not listed on the market

Shoe store tycoon Mahlon Haines built this landmark home in 1948 as an advertising gimmick. The house features a front door with a stained-glass portrait of the owner himself, an observation platform, and even a shoe-shaped doghouse. Fittingly, Mahlon once used the home as a guest house, offering weekend stays to elderly couples.

Decommissioned missile site, 1874 N Batum Rd,Othello, WA
Decommissioned missile site

10. Decommissioned missile site - 1874 N Batum Rd, Othello, WA 99159
Status: For Sale - $3,500,000

We saved the best for last and no - this is not a joke. This is a decommissioned military Titan 1 missile complex that is being listed as a potential residential property and it's for sale for $3.5 million in Othello, WA (about 3 hours east of Seattle). That's the "front door" in the photo to the right, which is a two-ton hatch that leads down six flights of stairs to a network of subterranean rooms and tunnels that all connect to a 125-ft diameter "superdome" with a 65-ft ceiling. According to Windermere real estate agent Kelvin Wallin, 18 Titan 1 missile sites were built during the years 1959-1962 between Colorado and Washington state. This one has three underground missile silos that measure 160-ft deep and 40-ft wide. According to Wallin, this site can withstand and survive any nuclear blast. Twenty years ago, a man purchased this property from the government and intended to turn it into a youth camp, but he died before he could realize his dream. Enjoy your own private well, generator power, and live off the grid. Not much curb appeal, but this beauty was built to last!

Indoor Air Quality-Green Desgn

Indoor Air Quality


 

For most people, terms such as "green design" and "sustainable building" conjure up images of high-performance spaces marked by ample daylight, rapidly renewable materials, water-efficient fixtures, and products made from recycled content.

But sometimes, a building that's seemingly good for the planet isn't good for the people occupying it. Many man-made products and materials—even those dubbed "good for the environment"—can off-gas, or release potentially harmful chemicals into a building's indoor air, which a building's occupants end up inhaling. These products include everything from a building's drywall, insulation, and flooring, to its paints, furniture, and cabinetry.

Paradoxically, some high-performance green buildings may worsen the problem by trapping these pollutants inside. Energy-efficient buildings are, by design, tightly sealed to minimize fresh outdoor air exchange and conserve energy; but this can cause airborne chemicals to amass indoors. This creates a "bubble" of hazardous pollutants—some of which are "respiratory stressors, neurotoxins, carcinogens, reproductive hazards, hormone mimics, and developmental toxins," according to a recent report by Environment and Human Health, a nonprofit organization that aims to protect humans from from environmental harm.

"Formaldehyde, acetaldehyde, xylene, toluene, benzene—the list can go on and on," says Henning Bloech, executive director of the GreenguardEnvironmental Institute, a third-party organization that certifies products and materials for low chemical emissions. "It's possible that one, some, all, or most of these chemicals are getting into the air we breathe inside our buildings simply because of product off-gassing," he says.

Moreover, tens of thousands of other chemicals that off-gas from everyday products have never been studied for their effects on human health, and thousands of other compounds are introduced into the marketplace every day.

When indoor air quality (IAQ) suffers, the building as a whole fails to meet the intent of sustainability, which is to minimize negative impact on both the planet and the people. Especially important is the IAQ of buildings intended for use by sensitive population groups, such as infants, children, the sick, and the elderly. In general, these groups are particularly vulnerable to short- and long-term health problems associated with chemical inhalation exposure, including headaches, nausea, nosebleeds, upper respiratory irritation, asthma, delayed cognition, reproductive disorders, and even cancer. And according to the EPA, studies show that exposure to poor IAQ can increase student and teacher absenteeism, decrease student performance, and lower student test scores.

In addition, the EPA considers IAQ a key determiner of employee productivity and attendance. Indoor air pollution, experts say, can lead to more sick days and decreased employee output. Asthma, which can be triggered by exposure to poor IAQ, accounts for over 13 million hospital, emergency room, andphysician visits each year in the U.S., according to the Centers for Disease Control and Prevention, and results in an average hospital stay of 3.2 days. "Sick Building Syndrome" and "Building Related Illness"—both of which can be costly for a building owner or facility manager due to worker absenteeism, loss of productivity, and occupant lawsuits—are often directly linked to indoor airborne chemical exposure resulting from off-gassing products and materials.

Fortunately, good indoor air quality isn't difficult to achieve. In fact, it starts with controlling the source of indoor air pollution: building products and materials. Specifying low-emitting products and materials can significantly reduce the number of chemicals that off-gas into the indoor air. But, a word of caution: When selecting low-emitting products, be wary of manufacturers that make eco-friendly claims without legitimate third-party, industry-independent data to support them. Remember, too, that not all certified "green" products account for a product's chemical emissions. For a complete listing of products that have been independently certified for low chemical emissions, check out the Greenguard Product Guide at greenguard.org. All products are searchable by sustainable credit qualifications, product category, and manufacturer.

By taking the proper steps early on, building and design professionals can help ensure the creation of healthier, greener, more sustainable indoor environments that will benefit generations to come.

Environmental Defense Fund

Dear Scotts,

Risk factor: A child plays outside formaldehyde-tainted FEMA trailers.

Did you know that deadly asbestos hasn't been banned by the U.S. government?

Help EDF close dangerous loopholes like this and protect American families from toxic chemicals.

In America, newborn babies enter the world with dozens of toxic chemicals, including fire retardants, lead and pesticides, in their blood.

I'm Richard Denison, Senior Scientist with Environmental Defense Fund's Health program and I've spent most of the last 25 years working to protect children and families from dangerous chemicals in our environment -- chemicals that are polluting even our newborns.

Unfortunately, U.S. laws regulating toxics are woefully inadequate. But you can help the EDF team fix these broken laws. I hope you'll consider supporting our efforts to close loopholes that are exposing our families to toxic chemicals.

No American is safe until we win reform.

For example, in the wake of Hurricane Katrina, our government used trailers made with formaldehyde-treated plywood to house homeless victims of the storm. As you may know, formaldehyde is a chemical that causes cancer and exacerbates asthma and other respiratory ailments.

This high-formaldehyde plywood -- which is imported from China -- is perfectly legal for use in the U.S. But because of its toxicity, it can't be used in countries including the EU, Japan, and even China has banned its residential use.

This is just one example of a dangerous chemical that is prevalent in our everyday environment. Asbestos, lead and fire retardants are all present in things we use daily. As is Bisphenol A -- a chemical used extremely widely (in everything from food can linings to baby bottles) that has recently been linked to altered brain development, recurrent miscarriage, and increased risk of breast cancer.

But there is hope. After years of pressure from Environmental Defense Fund (and other advocates for public health protection), the U.S. Senate introduced legislation to reform our outdated toxics law -- its first fundamental reform in more than three decades.

EDF will continue working hard to push for reform and ensure that dangerous chemicals are identified and restricted before widespread exposure occurs. Your support right now will help us keep the pressure on U.S. leaders to act.

EDF will also be working on the ground to deliver safer, greener products to Americans. For example, we are partnering with Walmart to evaluate everyday products like shampoo, laundry detergents and air fresheners for suspect chemicals. As Walmart incorporates these findings into its buying decisions, manufacturers who reduce or eliminate harmful chemicals from their products will have a competitive advantage over those who do not.

Fighting for protection from toxic chemicals is just one example of EDF's commitment to working with governments, business and communities to find strong, practical solutions to environmental health problems.

We're pleased to have you involved in our work and hope you will consider supporting our efforts.

Sincerely,

Richard Denison
Senior Scientist, EDF

    Insulation That Works

    With closed-cell spray foam, the benefits go way beyond R-value

    by Steve Easley

    These days, it's not an exaggeration to say that almost all homeowners expect their homes to be durable, energy efficient, safe, and comfortable. But this is especially true in coastal markets that cater to high-end clients who demand supreme quality and impeccable performance from their homes. Even in today's markets, which are euphemistically described as "relaxing," there seems to be no shortage of wealthy home buyers snapping up second-home properties along the coveted coast. If you build in this market, it's this kind of discriminating home buyer who will most expect you to get things right.

    In more than 25 years of consulting with builders on ways to reduce callbacks, I've spent most of my time solving problems related to heat and moisture transfer through buildings, because this is often where builders — even very good builders who deliver well-appointed homes to the coastal elite — get things wrong. Most of the serious (read "expensive") performance failures are moisture related, and a good number of these are closely tied to the thermal performance of the home. Yet I am surprised how often the insulation is installed without much thought or understanding about how it works. Consequently, very little attention gets paid to the details that really matter. Typically, fiberglass — selected as the least expensive option up front — is jammed in the walls and stuffed around electrical wires, plumbing pipes, and HVAC ducts, then covered up as soon as the municipality allows. The result is gaps, compression, and hollow voids that compromise occupant comfort and increase the building's energy loads. A sloppy insulation job can also lead to moisture problems by creating thermal conditions in walls and ceilings that promote condensation, wetting, mold growth, and rot.


    Batt insulation works best when it is fully lofted, not jammed into the tight spaces (above). Compression of the batt reduces the number of air pockets that provide the material's insulation value. It also leaves a hollow between the insulation and the drywall, creating areas where air can circulate. These voids can siphon off energy and may create conditions for condensation and moisture problems.

    Bright Star
    The updated Energy Star label for homes provides a quality standard that can guide builders away from these problems. New program requirements have raised the level of quality in the program, making it a label that savvy home buyers will more likely be looking for. As of January 1, 2007, a home that qualifies for an Energy Star label must pass a "thermal bypass inspection": a rigorous assessment of a home's air barrier. The bypass inspection requires builders to follow the EPA's Thermal Bypass Inspection Checklist — a 25-point list of details aimed at stopping the movement of heat around or through the insulation. Thermal bypasses — the defects that most commonly reduce the energy performance and comfort of homes — typically result from missing or compressed insulation, missing air barriers, and gaps between the air barrier and the insulation.


    The Energy Star Thermal Bypass Inspection Checklist must be completed by a certified home energy rater. However, in order for a home to qualify for the Energy Star label, up to six items may be verified by the builder to minimize required field trips by the rater.

    In my opinion, this checklist is one of the best guidelines to come out of the EPA's Energy Star program, and I think it substantially raises the bar for thermal and moisture performance of building envelopes. Of particular value to builders, the 86-page Thermal Bypass Checklist Guide (available free online at www.energystar.gov; search "Thermal Bypass Guide") provides a very practical and comprehensive look at reducing air infiltration. It should be required reading for anyone who's serious about building a quality home in any climate, but especially in demanding coastal climes.




    Living Spaces Over Garages
    Living spaces over garages create conditions that demand careful attention to insulating the floor. Yet it is difficult to support the insulation in this cavity, and oftentimes the insulation falls onto the garage ceiling. This separation between the insulation and the living space floor creates a thermal bypass that compromises the value of the insulation. Air easily infiltrates in at the band-joist area over the top of the insulation, which scavenges away heat. This often freezes plumbing pipes, creates cold floors, and can lead to major mold and water damage. Builders often try to solve the problem by supplying forced-air heat near the plumbing, but this only succeeds in pressurizing the space with warm, humid air. As this air exfiltrates through the exterior cracks, it can condense and lead to even worse moisture and mold problems at the band-joist areas.


    The issues are easily solved with ccSPF, which sticks to the bottom of the subfloor so insulation and air barrier are always in contact. The foam also stops air infiltration. It is a good idea to wrap any plumbing with a thin layer of fiberglass insulation before spraying foam over it to make servicing the plumbing easier.

    An Insulation for All Reasons
    I've included in this article a short catalog of some of the problem areas addressed on the Thermal Bypass Inspection Checklist that I find are frequently missed.

    What stands out about all of these problem points is that they can be difficult to get right with inexpensive fiberglass insulation unless a builder is working with an experienced and service-minded insulation crew. However, these problems are easily avoided when using closed-cell spray foam (ccSPF) insulation. This alone provides a strong argument for always using ccSPF, but it's certainly not the only reason.

    There are many reasons why ccSPF makes particularly good sense in a coastal home:

    • It has a high R-value of 6.5 to 7 per inch.
    • It absorbs a negligible amount of water. It can even be used as an effective secondary rain barrier and is the only FEMA-approved insulation for flood-resistant construction.
    • It does a good job of controlling diffusion.
    • It has good air barrier qualities to reduce airflow into and out of wall cavities.
    • It expands to fill voids in hard-to-
    insulate areas.
    • It provides some structural integrity to the frame (see "The Structural Properties of Foam," page 26).

    Attic Knee Walls
    These are areas where the insulation on the back side of unsheathed walls is exposed to outdoor temperatures and airflow. They are often adjacent to ventilated attic areas. The Energy Star Thermal Bypass Inspection Checklist requires that an air barrier be placed on all sides of the insulation. This means that the back sides of knee walls need to be sheathed and sealed. Thin-profile cardboard sheathing with ccSPF works well here. Since ccSPF is air impermeable, the insulation does not have to fill the entire cavity, and it meets the air barrier requirement. Some codes require R-19 insulation, which is difficult to do in a 3 1/2-inch space with batt insulation, but 2 inches of ccSPF provides about R-19.5.





    Sloping Roof Areas
    The sloping areas in a cathedral ceiling can be the sites for significant thermal bypasses. These areas are not only difficult to insulate but are difficult to ventilate. Yet ccSPF solves both problems. Placing ccSPF directly on the underside of the roof deck also creates a secondary rain barrier, and because of ccSPF's high R-value and low permeability, moisture is not likely to condense on its surface, eliminating the need for cavity ventilation.







    Band-Joist Areas
    The band-joist area is typically a major site for air infiltration. These areas are usually very poorly insulated, causing one of the most significant thermal bypass areas. If the home is under a positive pressure (air pushing out from inside) in a heating climate, the air is likely to be at a high humidity level. This can cause frost, and eventually mold, to build up on the back side of the band joist. In a cooling climate that is under negative pressure (air pulled inward — a condition that's commonly caused by leaky HVAC ducts), this can pull hot, humid air from outside, where it is likely to condense and lead to mold problems. The sealing properties of ccSPF will reduce these air-infiltration and energy-loss problems in this troublesome area.





    Attic and Crawlspace Bypasses
    Attic and crawlspace bypasses are penetrations into the living spaces. Pipes, ducts, flues, and electric wires are the most common reason for these penetrations, and the best way to seal them is often (but not always) with ccSPF. Because ccSPF expands and seals, it does an excellent job of filling voids that allow conditioned air to escape. However, ccSPF should not be used to seal around high-temperature areas such as combustion appliance flues.




    The Structural Properties of Foam

    Recent research conducted at the University of Florida has demonstrated that closed-cell spray foam (ccSPF) applied to the underside of roof decking effectively bonds the sheathing to the framing, significantly increasing uplift resistance. The study, conducted by Dr. David O. Prevatt and funded by Honeywell and Huntsman, two makers of ingredients that go into ccSPF, found that 3 inches of the foam sprayed between framing members provided a threefold increase in uplift resistance as compared with traditionally installed roof sheathing panels. While these results sound impressive, Dr. Prevatt points out that the increase provides the same benefits as increasing the nailing schedule to a 6/6 schedule (every 6 inches along panel edges and every 6 inches in the field) from the usual 6/12 schedule. What was perhaps most impressive is that using only spray foam to glue the sheathing to the framing provided almost as much resistance (178 to 209 psf) to uplift as does 8d common nails (205 psf) installed at the 6/6 schedule. This suggests what may be the biggest structural advantage of a foamed roof assembly — reducing the likelihood of a roof blowoff when the sheathing doesn't get nailed off with enough nails or when too many nails miss their mark.


    A test panel (left) in a study at the University of Florida simulates a roof assembly consisting of 1/2-inch OSB fastened to 2x4 framing at 24-inch centers. The framing bays have been filled with closed-cell spray foam. During the study, the assembly was placed on a pressure chamber and a vacuum pump (above right) drew a vacuum that was increased in 15-psf intervals until the assembly failed and the sheathing popped off the framing. For the fully foamed assemblies, this occurred at around 240 psf. The assemblies that had ccSPF fillets installed failed at 160 psf. The assemblies with sheathing alone nailed only with nails (6/12 schedule) failed at about 75 psf.

    The uplift study also evaluated the benefit of installing a "fillet": a 3x5-inch bead of ccSPF in the corners between the sheathing and the roof framing. The fillet method effectively doubled the uplift resistance of the baseline assembly of 2x4 framing on 24-inch centers sheathed with 1/2-inch OSB nailed on a 6/12 schedule.

    The uplift study is one of several recent studies of the structural properties of ccSPF. Tests conducted by Building Science Corporation (BSC) to evaluate the impact resistance of wall systems showed that conventional wood-framed walls do not have the same impact resistance as impact-resistant windows. (That is, walls consisting of studs, 1/2-inch OSB sheathing, housewrap, and siding cannot sustain the impact required by the ASTM E1886 and E1996 missile test, which hurls a 9-pound 2x4 at 50 feet per second.) The only test panel in the BSC demonstration capable of resisting the required impact load included a layer of 1/2-inch OSB sheathing between 1-inch foam insulating sheathing and 2 inches of ccSPF sprayed between 2x6 studs. Surprisingly, BSC found that a wall with foam sheathing, housewrap, and ccSPF (no OSB) performed better in impact tests than a wall with housewrap and OSB sheathing.


    When a roof is not likely to be replaced anytime soon and the sheathing nailing can't be verified (on a tile roof in good condition, for example), contractors in Florida are beginning to employ the "fillet method." This practice uses closed-cell spray foam to help bond the roof sheathing to existing framing and provide a secondary water barrier.

    The BSC study notes that walls may not have to be built to the same standard as windows, despite these surprising results. When a window fails under impact, the resulting hole in the wall (the entire window) is relatively large, providing a big enough hole to internally pressurize a home, which often leads to catastrophic failure. When a wall fails, the zone of impact is marginally bigger than the impacting face of the projectile. Such an opening may not be large enough to have a catastrophic effect. — Clayton DeKorne

    Smart Grid-Super Conductors-Transmission Line Upgrade

    Superconductors carry electricity without resistance


    Dallas, August 16, 2010—New second-generation superconducting materials can now carry as much as 100 times the current of ordinary conductors such as copper. Furthermore, these superconductors carry electricity without resistance, so there are no losses during transport.

    These dramatic advances in electricity transmission will be a main attraction next month when the Institute of Electrical and Electronics Engineers (IEEE) unveils its world energy conference, styled Innovative Technologies for an Efficient and Reliable Electricity Supply, at a hotel in Boston September 27 - 29. The public is welcome to attend by registering at the website.

    Keen attention will focus on an exhibit and presentation by SuperPower located in Schenectady, N.Y. "The main focus of our work is on the development and manufacture of second-generation high-temperature superconducting wire (HTS)," said Trudy Lehner, senior director. "Benefits include greatly reduced power losses, elimination of pollution and fire hazards, easier siting ... due to the improved energy density they can be sited in locations that are not possible now."

    Of course wire is the enabling component for a wide variety of devices in the energy and alternative energy area: underground ac and dc power cables, power transformers, fault current limiters, superconducting magnetic energy storage devices, wind turbine generators, etc.

    In addition to improved reliability and quality of power, HTS devices are smaller and lighter than conventional devices, reducing the amount of space required in substations. The size and weight benefit also addresses important requirements for wind turbine generators and increased operational flexibility for the utility grid.

    Art Kazanjian, general manager of SuperPower, joined Lehner as they gave a preview on what the firm will be presenting at the conference in comments by phone from their office on the ScienceNews Radio Network program, the Promise of Tomorrow with Colonel Mason. The broadcast originated in Dallas, Texas, and can now be heard archived at the website for a world audience.

    "We partner with other organizations to demonstrate the technology by designing, building and installing prototype devices," Lehner told their radio audience, "for example the Albany HTS Cable Project, a demonstration of that technology in a 350 meter long second-generation HTS cable that was installed on the National Grid system in Albany, N.Y. Partners were Sumitomo Electric Industries and Linde, in addition to National Grid. Funding was from the U.S. Department of Energy and the New York State Energy Research and Development Authority."

    Subject: Just left a meeting with the White House...

    Date: Friday, September 10, 2010, 3:03 PM


    The White House refused to accept our offer of a free solar panel installation on 10/10/10.

    That's why we need to lead by example, and show our leaders how work gets done. 

    Can you start or join an event in your community on 10/10/10?

    Take Action
    Dear friends,

    I just walked out of a disappointing meeting with the White House: they refused to accept the Carter solar panel we came to Washington to deliver and said that they would continue their "deliberative process" to discuss putting solar panels back on the White House roof.

    Well, we're done deliberating. When Pakistan is under water, Russia is on fire, and millions of people are ready for clean energy jobs, it's not time to deliberate: it's time to get to work.

    Today marks the one month countdown to the 10/10/10 Global Work Party. Will you help us celebrate by signing up to
    register or attend an event today?

    We entered this morning's meeting buoyed by the over 40,000 of you who signed our letter requesting President Obama to make the retrofit. We were equally heartened by the hundreds of work parties that have been registered since our road trip began on Tuesday. And we were humbled by reports of the amazing work being planned in places like Zimbabwe, where a group of students will be installing solar panels on the roof of a rural hospital for 10/10/10.

    I'm also incredibly proud of the three students from Unity College who stood right up to the officials we met with and explained to them that if they wanted to communicate about the greening of the government they should do something in a place where people pay attention.

    This week's road trip got incredible media coverage in places like Newsweek, the Washington Post, USA Today, and more. Thousands of you helped spread the word on Facebook and Twitter. Hundreds of you signed up new work parties to show how you're leading this movement for climate solutions. Because in the end, that's what it is going to take: a movement.

    Your efforts are building incredible momentum. In the last month, big partners like Greenpeace, Rainforest Action Network, Sierra Club, and the World Council of Churches have joined the 10:10 Campaign and 350.org in planning for 10/10/10. The day will be a moment to bring our entire movement together and show our so-called leaders what real leadership looks like.

    As for the Carter solar panel, it's going to stay in Washington for now, ready for President Obama to come take it home. And as for me, I'm going to head home myself for a few days of rest before hitting the road again to drum up support for 10/10/10.

    Your hard work means the world to us, let's keep up the fight.

    Onwards,

    Bill McKibben

    350.org is an international grassroots campaign that aims to mobilize a global climate movement united by a common call to action. By spreading an understanding of the science and a shared vision for a fair policy, we will ensure that the world creates bold and equitable solutions to the climate crisis. 350.org is an independent and not-for-profit project.

    What is 350?
    350 is the number that leading scientists say is the safe upper limit for carbon dioxide in our atmosphere. Scientists measure carbon dioxide in "parts per million" (ppm), so 350ppm is the number humanity needs to get below as soon as possible to avoid runaway climate change. To get there, we need a different kind of PPM-a "people powered movement" that is made of people like you in every corner of the planet.
