Efforts infiltration green bags on the roofs of buildings and structures are commonly known as roof gardens, green space or roof garden roof.

The existence of roof garden will add economic value for residential buildings which are equipped with a roof garden would feel more comfortable and visually beautiful. Benefits roof garden especially extensive in improving air quality and enhance environmental quality including:

Absorption of heat in the building is reduced by 10%. This means you can economize up to 60% of energy consumption used to cool the air. Temperatures in space can come down at least 1-2 celcius degrees, depending on the area of the roof garden.

The existence of the forage, especially the plants with leaf surface rough or jagged edges, especially potent to reduce noise for residents in the building.

Jochen Flasbarth, president of the Federal Environment Agency – a German government agency which deals with environmental issues – German target is not a dream in the daytime, because of technical and ecological point of view this target it is possible to achieve.

From the technical side, recently Germany has reached 16% of electricity from potential wind, solar and other renewable energy sources. This figure tripled from the previous fifteen years. Solar energy itself is almost reached 14 GW in this year and become the second country after the United States in the production of electricity from wind energy.

While the environmental side, from 1990 until 2020, Germany succeeded in reducing greenhouse gas emissions to 40%.

A study carried out by the agency also confirmed that the switch to electricity sourced from renewable by 2050 will provide an economic advantage, especially for export-oriented manufacturing industries. Besides tens of thousands of new jobs will be created simultaneously with the development of technologies and renewable energy industries.

The magnitude of the cost required to replace the entire supply of electricity from renewable energy sources is much smaller when compared with the costs of future generations of Germany if the problem of climate change is a major problem of the country.

Heat pumps [...]]]> Researchers at Purdue University are working on a new research project that promises the potential to cut heating bill in half for those who live in very cold climates. The study, funded by the U.S. Department of Energy, builds on previous work that began about 5 years ago at Purdue’s Ray W. Herrick Laboratories.

Heat pumps provide heating in winter and cooling in summer but aren’t efficient in extreme cold climates. The published research involves changes to the way heat pumps operate to make them more cost-effective in extreme cold temperatures.

The modern technology works by modifying the conventional vapor-compression cycle behind standard air con and refrigeration.

The usual vapor-compression cycle has four stages:
1° Refrigerant is compressed as a vapor
2° Condenses into a liquid
3° Expands to a combination of liquid and vapor
4° Then evaporates

The project will investigate two cooling approaches during the compression process.
In one approach, relatively a lot of oil are injected into the compressor to absorb heat generated through the compression stage.
In the second approach, a combination of liquid and vapor refrigerant from the expansion stage is injected at various points during compression to supply cooling.

The newest heat pumps might be half as expensive to operate as heating technologies now utilised in cold regions where gas is unavailable and residents depend on electric heaters and liquid propane.

In the meanwhile here some tips to improve you home air quality and save energy:

- Be certain your thermostat is located in a spot that is not too cold or hot.

- Install an automatic timer to maintain the thermostat at 68 degrees in the daytime and 55 degrees during the night time.

- Use storm or thermal windows in colder areas. The layer of air between the windows acts as insulation helping to maintain the heat inside the spot where you are interested.

- If you haven’t already, insulate your attic and all outside walls.

- Insulate floors over unheated spaces such as your basement, any crawl spaces and your garage.

- Close off the attic, garage, basement, spare bedrooms and storage areas. Heat only those rooms that you use.

- Seal gaps around any pipes, wires, vents or other openings that could transfer your heat to areas that aren’t heated.

- Dust is a wonderful insulator and tends to build up on radiators and baseboard heat vents.

A lot of people don’t know that common indoor air quality practices lower home air heating costs too:

- Rain and high humidity can bring moisture indoors, creating dampness, mold and mildew — big problems for healthy indoor air. Look at your roof, foundation and basement or crawlspace once a year to catch leaks or moisture problems and route water away from your home’s foundation.

- Keep asthma triggers away from your house by fixing leaks and drips once they start. Standing water and moist encourage the development of dust mites, mold and mildew — probably the most common triggers that can worsen asthma. Make use of a dehumidifier or air conditioner when needed, and clean both regularly.

- High amounts of moisture at home increase dampness and the growth of mold, which not only damage your house but threaten health. Install and run exhaust fans in bathrooms to remove unhealthy moisture and odors out of your home.

- Ventilate your kitchen stove directly outside or open a kitchen window when you cook. Keeping exhaust — including cooking odors and particles — outside of your home prevents dangerous fumes and particles from harming you or your family.

The company introduced a battery of organic research findings by researchers at the University Hebrews that made from potatoes and has been getting special treatment in order to improve its ability to connect the oxidation and reduction in galvanic cells or so-called salt bridge.

Professor Haim D. From Robert H. Rabinowitch Smith Faculty of Agriculture, Food and Environment, Alex Golberg research students from the School of Computer Science and Engineering, both from the Hebrews University, together with Professor Boris Rubinsky of the University of California at Berkeley, is basically intended to study the electrolytic process that occurs in living organisms to applied to the various applications.

In their research they found that the use of zinc and copper mounted on a boiled potato to produce electricity for up to 10 times more than potatoes that is not boiled. From the results of cost analysis, the potatoes battery can five to fifty times cheaper than commercial 1.5 volt battery.

If you are interested to try it, please do a little experiment with various kinds of tubers or fruits, because according to the researchers it can produce electricity with all necessary conditions that given special treatment in advance in order to generate electricity.

As quoted from the press release Honda, Honda hybrid car will be released into the market on August 24, 2010 at a price of U.S. $ 19,950.

Honda hybrid cars are reminiscent of the Honda Civic CRX in the 90s, which is preferred among teenagers and young adults. This time it seems Honda is also targeting the same market. It is shown from hybrid design that clearly illustrates the spirit of youth.

Two-passenger car CR-Z is relying on six-speed manual transmission, although actually in the ranks of the CR-Z families have some type when viewed from the transmission and completeness.

CR-Z itself is available in two options, manual transmission and transmission CVT (continuously Variable Transmission) that makes the transfer of transmission will not be felt. CVT transmission CR-Z released a price of U.S. $ 20,700.

Besides the CR-Z also provides the type CR-Z EX (manual transmission and CVT) and CR-Z Honda EX equipped Satellite-Linked Navigation System and Voice Recognition. Unfortunately the last two types are only marketed in the United States.

CR-Z has several features, including AM / FM / CD / USB sound system, automatic climate control, remote, cruise control and power windows and lock. Safety factor is the priority on Honda. CR-Z hybrid version is equipped with an optional security features such as Antilock Braking System (ABS), airbags in front and side passenger and driver, the system monitors the air pressure in tires and many other security features.

From the side of the engine, the CR-Z is equipped with four-cylinder hybrid engine with a capacity of 1500 cc combustion chamber capable of producing 144 horsepower at 6000 rpm rotation and Honda electric motor system called Integrated Motor Assist (IMA) and produced 13.5 horsepower . Combination of the two machines are able to save significant fuel.

Wall of a dark color will absorb heat between 70-90% of the total solar radiation that hit the area. Some of this heat would go into the house by way of conduction in the wall that would lead to heat inside the house. This would increase the energy needed to cool the room up to 20%.

The bright colors will reflect most of the rays and heat away from your home. The color is not necessarily white, but a green or blue color is good that is more bright color.

Wall with vines can also protect the wall from the heat by putting blocks sunlight and reflected it in advance. Select vines that is easy to care.

Even the smallest contribution will continue to conserve our energy and improve the environment.
