Housing foreclosure rates decline

This article is excerpted from the CRS Weekely on-line news letter:
Foreclosure Activity Continues to Decline


Foreclosure filings, including default notices, scheduled auctions and bank repossessions, were reported on 212,764 U.S. properties in July, a 4 percent decline from June and 35 percent from a year ago, according to the latest data from RealtyTrac, an online marketer of foreclosures. One in every 611 U.S. homes had a foreclosure filing during July, marking the 10th straight month of annual decreases in foreclosure activity and the lowest monthly total since November 2007.

“This string of decreases was initially triggered by the robo-signing controversy back in October 2010, which forced lenders to substantially slow the pace of foreclosing, but the downward trend in foreclosure activity has now taken on a life of its own,” says James J. Saccacio, RealtyTrac’s CEO. “It appears that the foreclosure processing delays, combined with the smorgasbord of national and state-level foreclosure preventions efforts — including loan modifications, lender-borrower mediations and mortgage payment assistance for the unemployed — may be allowing more distressed homeowners to stave off foreclosure,” he says.

Default notices fell 7 percent during the month from June and decreased 39 percent from July 2010. Foreclosure auctions fell 5 percent from June and declined 37 percent from a year ago. While bank-owned properties slipped 1 percent from the previous month, they were 27 percent below July 2010.
For the 55th straight month, Nevada posted the nation’s highest foreclosure rate, with one in every 115 homes receiving a foreclosure filing during the month. California had the nation’s second highest foreclosure rate, with one in every 239 homes receiving a foreclosure filing, followed by Arizona, with one in every 273 housing units receiving a foreclosure filing.

5 Indoor plants which help air Quality in your Office

This is excerpted from the Ecofriend Web site:

Indoor plants are generally grown for decorative purposes and for refining the air too. According to a research carried out by NASA, some plants serve as better air purifiers than others. Here is a list of some commonly grown indoor plants which serve as natural air purifiers:

1. English Ivy

Botanical Name- Hedera helix

English Ivy is an evergreen plant and has a long life span. It is a trailer and can be grown on the sides of wall and fences. The plant needs indirect sunlight and average to cold temperature for its growth. It prefers cool soil, sufficient moisture and good drainage. Use balanced fertilizers for the soil and guard the plant against mites. The plant proves to be dangerous and can cause skin irritation. So, it is advisable to wear gloves while handling the plant. Also, make sure that the plant is kept away from pets. The plant can be propagated by stem cutting.

English Ivy removes some common pollutants, like benzene, toluene and formaldehyde.

 

2. Spider Plant

Botanical Name- Chlorophytum chlorosum

It is a preferred and suitable house plant. The plant produces long stems as it grows. The leaves along with the flowers give the impression of spiders hanging from the strings. The plant is easy to grow and can tolerate extreme conditions of temperature and moisture. But, sufficient bright light is the prime requirement for the plant. The plantlets can be easily propagated and look beautiful when grown in hanging baskets along with other plants. Do not expose the plant to cold draft.

Pollutants removed by Spider plant - Formaldehyde

 

3. Peace Lily

Botanical Name- Spathiphyllum ‘Mauna Loa’

This is a popular house plant and can grow in little sunlight. Watering can be done just once in a week. Over-watering can cause browning of leaf tips. Peace Lily can be easily propagated and it blooms in early summer. The plant should be fed monthly with liquid fertilizers in summers and spring season. One plant should be grown in an area of 10 meters square and fertilization should be done only in summer and spring season.

Pollutants removed by the plant - Benzene, formaldehyde and others.

 

4. Chinese Evergreen

Botanical Name- Aglaonema sp.

This is an ornamental and a long-lasting plant. The plant is easy to grow and requires indirect sunlight and high humidity. Keep the plant in warm condition and in heavy and moist soil. The plant should be guarded against low temperatures as it cannot tolerate cold. If the leaves start turning yellow, it might mean that too much sunlight is falling on it. Immediately remove the yellow leaves and transfer the plant to low light area. Aglaonema can be easily propagated. Make sure that you clean off the leaves regularly.

It is a useful plant and removes benzene, toluene and ammonia from the air.

 

5. Reed Palm

Botanical Name- Chamaedorea sefritzii

Another name of this plant is Bamboo Palm. It is a long-lasting, small or medium sized plant and can grow to a height of six meters. The plant can flourish best in medium light and high humidity. The palm should be planted in a pot which has a hole so that the soil is uniformly moist and continuous drainage takes place. Rain water is best for watering this plant. Palms are easily infected by mites and bugs indoor. The plant should be fertilized regularly during its growing season.
Reed plant purifies the indoor air against trichloroethane, benzene and toluene.

10 eco friendly gadgets that produce water from air

Balakrishnan Ramachandran:



atmospheric condensationwater vapor in air condenses when it cools below dew point

Water availability has already become a major concern area for humankind. Some UN studies already estimate that some 1 billion people worldwide do not have access to adequate drinking water. Water borne diseases already account for over 50% of preventable human ailments in the poorer regions of the world.Even in the more advanced regions of the world, municipal water supply is no longer considered safe enough to drink. This has spawned a $ 50 billion packaged drinking water industry.

The atmospheric air always has water vapor present in it. This is part of the Hydrologic cycle, where water evaporates from the seas and other water bodies, the vapor is carried by air into the upper atmosphere where it forms clouds which then condense into water as rain or snow. The total water vapor in the atmosphere is so large that it can meet all of human water needs.

Scientists and engineers are attempting to find means to extract water from the air without waiting for the natural rain cycle. The two basic processes to extract water from air are cooling condensation and wet desiccation. Cooling condensation is the familiar sight we see of water droplets forming on the outside of a bottle or glass of any cold liquid. The air in the atmosphere is cooled below its dew point by contact with the bottle or glass,causing the water vapor in the air to condense. Desiccant cooling is illustrated by the fact of common salt in a salt shaker becoming damp by absorbing water vapor from the air.Many commercial air-to-water devices have now become available. Some alternative approaches are also being attempted. An air-to-water industry appears to be developing

Condensation cooling

1. Using natural stone structures for condensation

Examples of condensation cooling exist even from early human civilization. In some parts of Europe and the Middle East, there are 10 meter tall beehive-like stone structures dating from the 19th century, called air walls. The stones cool rapidly in the night. When moist air comes in contact with these stones, the condensation yields water that is collected in troughs inside the structure and used for drinking and washing.In France, these structures were also used in some vineyards.

2. Using water nets for condensation

This is the modern adaptation of the ancient stone walls for water harvesting. At a village named Cabajane in sub-Saharan Africa, a team from the South African Agricultural University helped the villagers string up plastic nets across a mountain pass. The clouds and fog through the pass, condensed water on the nets, which ran down through plastic pipes to be collected in a tank. Several hundred liters of potable water became available to the village from this simple device , where they earlier had to walk over 2 km to the nearest stream. This experiment is now being replicated in other villages in sub-Saharan Africa and also in Chile and in some places in Nepal.

3. Foldable structure for water harvesting

Two Israeli architects, Joseph Cory and Eyak Malka have designed this foldable triangular structure, named WatAir, that is said to imitate the leaves of a tree to condense atmospheric water vapor and collect it into a tank. The structure folds into a a package of 1 meter maximum dimension and 3.5 kg weight, that the designers claim can be erected anywhere, to harvest atmospheric water.

4. Max Whisson’s Gust Water Trap

Dr Max Whisson of Perth, Australia has come up with a wind turbine design that produces water by condensation, instead of electricity. The wind turbine has vertical blades and is mounted on a swivel with a wind vane tail, so that it can turn to face the direction of the wind. When the turbine turns, the wind gets forced into the hollow tower. The air passes over a refrigerant compressor driven by the wind turbine and condenses into water, that flows into tanks at the base of the tower. A company named Water UN Limited has been formed to commercially apply this technology.

5. Windmill to make water from air

The company Dutch Rainmakers of Netherlands has installed a windmill Surinam to produce water instead of electricity. In their design, the air is forced through a heat pump, where the water vapor condenses. This heat pump replaces the refrigerant compressor. The wind mill is said to produce 5000-7000 liters a day, a real boon in a place where the groundwater is brackish.

6. Refrigerant based condensation

The modern condensation cooling devices, generally use a refrigeration coil to provide the cooling. Many manufacturers worldwide have come up with condensation cooling machines that work on the following principle.Inlet air is filtered to remove dust and suspended particles using fabric filters. This air is passed over coils containing cold refrigerant gases. The condensate water is collected in a stainless steel tank and exposed to ultraviolet light for about 30 minutes to remove bacteria and then filtered through an active carbon filter. The typical cost for a model that produces 20-25 liters a day is about $ 1500 and these machines consume about 500 watts of electricity. These condensation machines are styled like the conventional water coolers installed in offices and public places, and are intended to be used in such locations.

One of the largest companies in this field appears to be Air Water Corporation of Miami Beach, Florida which makes a range of machines from the 25 liter per day single office type capacity to larger 2500 liter per day trailer mounted machines complete with their own diesel power generator that can be installed at a construction site or even in a village as they have done in Jalmudi in India. Air Water Corporation says that its products are sold in 21 countries through local affiliates.

Another company that has targeted the home user with this technology is Element Four Technologies Inc.,of British Columbia, Canada which has launched an attractively packaged product they have named the WaterMill. The home model is dsigned to produce 11 liters of water per day enough to meet the drinking needs of a small family. The air intake and condensation is planned to be mounted outside the home and the potable water tank inside the home ( like a split air-conditioning unit). An upgraded model for 20 liters per day in planned. However, there are many companies with product variants for this market.

7. DRIPS for growing crops with water from air

Two high school students from San Francisco, with mentoring by professors from the University of California, Berkeley, have proposed this system for water harvesting from air. DRIPS stands for Deep Root Irrigation Precipitation System and is made of a 1 foot diameter, or larger, plastic or aluminum conical surface mounted on a hollow tube that is buried 1.5 feet into the ground. The plastic or aluminum surface cools in the night and in contact with air, causes water droplets to condense. This water, by capillary action aided by small ribs on the cone, drains into the ground. The depth of 1.5 feet prevents this water from evaporating back into the atmosphere and helps nourish the roots of plants. This method of water harvesting has been demonstrated to grow potatoes.

8. Fraunhofer Institute’s brine tower

The Fraunhofer Institute of Interfacial Engineering and Biotechnology (ICB) in collaboration with the company Logos Innovationen is working on this concept of a tall tower like structure down which hygroscopic brine solution runs down. This brine in contact with air absorbs moisture and runs into a tank at the base of the tower which has a slight vacuum. The tank is heated with solar collectors that causes the brine solution to boil. The vacuum in the tank lowers the boiling point of the brine solution.The water absorbed from the air evaporates and is led out through a tube filled with water. This water column maintains the vacuum in the tank without the need for a vacuum pump. The brine is recovered and pumped up again to flow down the tower.

9.Liquid desiccant for water harvesting from process air

Sciperio Inc., an Orlando, Florida based technology is working on using liquid Lithium Chloride as the desiccant to remove water from air. Their finding is that this is more energy efficient than using refrigerant based water harvesting technology and have proposed using this for water extraction from air in process plants for industrial use, rather than for drinking.

10. Use of solar energy for regenerating the desiccant

One variant of the use of wet desiccation by the company A2WH of Atlanta, Georgia which uses a proprietary desiccant for water vapor absorption. This desiccant is heated by solar energy to expel the absorbed water. The unit, installed outdoors, also has photo voltaic panels to generate the electricity needed for operating the units pumps and valves. A2WH says it has models both for the individual home and for irrigation of farms.
