Save Our Planet With Hydrogen Fuel Cells

Tuesday, November 10th, 2009
Have you heard about water fuel? Well, it is properly called hydrogen fuel cell technology and it is here to save the planet. Oil and gas prices are soaring higher and higher and there will come a time when people realize that they should consider an alternative fuel energy source.

Admit it, everyday your car emissions are contributing to pollution. If you want to reduce pollution and at the same time save money, you need to make use of hydrogen fuel cell technology; find out more by reading this article.

Hydrogen fuel cell technology is not new. It started more or less eighty years ago but since it is quite expensive, scientists and researchers don’t find it a good alternative fuel source. Aside from the hydrogen technology, other technologies have surfaced years ago such as the use of vegetable oil and sugar cane to run a car. However, these technologies did not achieve great success because of the hefty price, climate restrictions, and other issues regarding safety on the road. In short, these technologies were unstable.

Hydrogen fuel cell technology is different. In fact, there are now converted hydrogen cars roaming the streets of US, Europe, and Canada. This improved technology is now more stable. Have you tried surfing the internet? The hydrogen fuel cell kits are widely available online and anyone can get it as long as they want to take advantage of the hydrogen technology.

Experts did not find vegetable oil and sugar cane as viable options. Can hydrogen technology offer something different? If you want proof, the technology is proof in itself since it is science reality. With hydrogen technology, you will still need gasoline aside from the HHO generator and conversion tool.

The conversion tool will need electricity from the car battery and this will be used to conduct the process of electrolysis. Through the process, hydrogen will be extracted from water and in turn provide the car with added power. Obviously, at this point in time, hydrogen technology can’t replace the use of diesel or gasoline. Well, who knows what might happen in the future.

By using this hydrogen fuel cell technology, you can reduce your fuel consumption to a great extent and save lots of money. Now, why did scientists and researchers find this technology viable? The reason is that hydrogen technology is much more affordable now. In fact, car companies will soon offer the public with affordable hydrogen powered vehicles.

Conversion projects are easy to build and are quite affordable. If you’re interested with the hydrogen technology, surf the net now. Check out the available resources that are in store for you. You will surely get tremendous savings by simply investing on the fuel cell kits online.

Even if you buy the built fuel cells, the cost is still nothing compared to the savings that you will get in return. Well, if you want changes, you definitely have to spend some money. This is a very good investment because you’re not only helping yourself but you’re also helping the world.

Find guides online to help you go through with your conversion project. Perhaps you have a friend or a relative who converted their car already. Ask help from them so that the task is immediately finished. If everyone in the world consider the use of hydrogen fuel cell technology, life will improve.

Waste Management and Skip Bins

Wednesday, October 28th, 2009
What is waste management? Simply put it is the collection of waste materials produced by human consumption and activity, transporting it to a facility that will treat it and then the recycling of the waste material, or if it is not reusable, disposing of it for good. Recycling products and materials is becoming the norm due to the growing understanding of the effects it has on our environment; concern about waste disposal practices to our surroundings and is an important issue to companies and local governments. Once, the management of waste would have meant the dustbin truck taking your refuse and transporting it to the local rubbish tip. Fortunately rubbish tips are no longer regarded as an appropriate solution to dealing with waste; refuse, garbage, trash, rubbish, scrap, however you want to name it, is now being accepted as a valuable resource that shouldn’t only be land filled but found many valuable and resourceful uses for.

Governments and private companies aim to control waste by offering facilities to households and businesses to dispose of it, one of the main methods used are the provision of skip bins. Skip bins can be hired to collect a variety of waste including food, plastics, metal, furniture, timber and construction, garden and electronic waste. The kind of skip bin required will depend on the type of materials you are planning on disposing of. For example, green waste skip bins are used for anything from tree clippings to grass and hardfill skip bins for substances like concrete, soil, rubble and tiles. Hazardous chemicals and contaminated waste can’t be put into skip bins due to the dangers involved and so for these materials it is necessary to call the local council and they will advise on how to dispose of them, hazardous substances include acids, solvents, cyanide waste materials, paints and oils. There are also bulk bins and skip bin hire solutions for the collection of refuse from businesses such as building and construction sites, large size developments and industrial companies. As well as skip bins, amenities are provided to safely dispose of and destroy private documents such as quarantine stock, computer hardcopy, tapes and microfiche and out of date products. Electronic waste is also recycled these days and includes components from disused computers and other IT equipment. Collection and treatment services exist for clinical and medical waste from businesses and industries such as laboratories, surgeries, veterinaries, dental surgeries, food processing plants and hospitals.

The skip hire industry and resource recovery facilities are particularly essential for the future of the environment as they create an awareness of how everyone can help in increasing the amount of waste recycled and thus reducing landfill. Nations all over the world are joining in the attempt to find ways of recycling waste, from using complicated methods to change the calorific content present in waste into electricity or sorting through landfills to remove recyclable materials and reduce the amount of waste that needs to be disposed of. Waste management is an ongoing problem for society, a problem that will never go away, but if managed effectively, can be controlled.

Grid Tie Renewable Energy Setup

Saturday, October 17th, 2009
A common route to take when you decide to switch over to renewable energy is a “Grid-Tie” setup. What this means is your house is tied in with your renewable energy system and tied in to the power grid. The reason this is such a popular route to take is that it allows you to move to renewable energy as you can afford it.

The beauty of a grid-tie system is that it can be configured two ways. The first way is to set up your system with solar panels and wind generators and hook them up to a battery bank. This battery bank is then hooked up to an inverter and powers some of the appliances in your home. This system costs more and is harder to install for several reasons. Firstly, you need to do some re-wiring of your home to integrate you renewable energy system. This requires a licensed electrician and can be a time consuming process. Secondly, you have to buy a battery bank to store the electricity that you generate.

The second setup which is more cost effective and easier in the long run is to simply wire your system directly into the power grid. What this means is that the electricity you produce is being fed through your meter. It’s really cool to watch it spin backwards. There are some things that you should know about this setup though. You will have to check local laws to see whether this type of system is allowed, and you will have to check with your energy company to see whether they will allow you to run this type of system. Lastly, you will need a licensed electrician to do the setup. This way has several advantages though. You don’t need to initially spend a huge amount of money to get up and running, and expanding simply means hooking another solar panel up. You also don’t have to do any re-wiring to your house.

As time goes on you can add solar panels faster because your electricity bill has gone down, and after it reaches $0 you can start buying batteries for the storage system.

For those of us who can’t afford to make the switch to off grid living all at once this is the way to go. It allows you to build your system one piece at a time as you can afford it. It may take you 2-5 years to get running completely on renewable energy, but it is definitely worth it.

Promotion of Green Building Construction Technique

Wednesday, October 7th, 2009
Construction of Green Building is a technology to use all resources efficiently for the creation of human habitats which improve human health, build a better environment, increase working efficiency of human beings and minimize the cost of buildings. Green buildings are also known as sustainable buildings, which are designed, built, renovated, operated and used in an ecological and resource-efficient manner.

In fact, Green buildings are designed to meet certain objectives such as protecting occupant health; improving employee productivity; using energy, water, and other resources more efficiently; and reducing the overall impact to the environment. These buildings with good overall environmental quality can reduce the rate of respiratory diseases, allergy, asthma, sick building symptoms, and enhance worker performance. The green building construction technique include following elements:-

Elements of Green Building Construction Technique

1. Proper Ventilation

Green Buildings provide adequate ventilation to all habitable rooms including bath rooms, kitchens with high-efficiency in-duct filtration system to allow proper drainage of air-conditioning coils to control humidity including heating and cooling systems which ensure indoor air quality.

2. Prevention of indoor microbial contamination

Under this technology, construction and finishing materials are selected with zero or low emissions to improve indoor air quality. Many building materials and cleaning / maintenance products emit toxic gases, such as volatile organic compounds (VOC) and formaldehyde gases which result in a detrimental impact on occupants’ health and productivity. Such products are not to be used in building construction and their finishing.

3. Utilization of recycled material for minimizing the cost of building

Demolition and reconstruction of old buildings is a continuous phenomenon. Population and demand for buildings are increasing day by day whereas our resources are depleting in the same proportion. Building construction activities consume one-sixth of the world’s fresh water withdrawals, one-fourth of its wood harvest, and two-fifths of its material and energy flow. About 22 percent waste material (bricks, concrete, wood, steel, metals, steel pipes, plastic pipes, electric wires, sanitary material etc.) of demolished buildings can be reused or recycled thus prolonging our supply of natural resources and minimizing construction cost. In green buildings, about 25 % recycled material is used.

4. Installation of glass panels

Instead of wood window glass panels are installed in green buildings to allow flow of natural light inside the building during day time.

5. Installation of Rainwater Harvesting System

The green buildings are well equipped with rainwater harvesting system to preserve depleting water resource.

6. Maximizing the use of renewable natural resources

In order to maximize the use of renewable natural resources in green buildings, the energy efficient equipments such as Compact Fluorescent Lights (CFL) and Solar Water Heating Systems etc. based on non conventional energy resources are installed.

7. Minimizing The Use of depleting resources

Since, forest cover is depleting day by day in the world, therefore, use of fresh wood is minimized in green buildings. Wherever, use of wood is considered necessary, in such buildings, the wood of fast growing trees is only used so that utilization of such material may not effect the ecological balance of the earth.

8. Minimizing energy use in green buildings

The green buildings are fixed with energy censors to minimize the use of power within the building. When there is no person within a room, the lights would automatically go off.

9. Water conservation and efficiency measures in green buildings

In green buildings, water is used in most efficient way. The gray water from bath rooms is again recycled to flush toilets.

10. Proper disposal of garbage

The garbage of green buildings is properly handled, placed and disposed off as per Building Bye Laws of respective Civic Bodies by segregating it into biodegradable and non-biodegradable wastes.

11. Maintenance of greenery

In green buildings, the open areas are well landscaped with maintenance of maximum greenery for building healthy environment.

Trends in Green Building and Sustainable Construction

Wednesday, September 30th, 2009
“Green Building” is a broad term used to describe the design and construction of sustainable and environmentally conscious buildings.

The driving force behind this is to lower our negative impact on the environment and, at the same time, make the buildings we live and work in safer and healthier for us.

According to the United States Green Building Council (USGBC) statistics,`buildings are responsible for all of the following:

39% of US carbon dioxide (CO2) emissions

70% of US electricity consumption

15 trillion gallons of water consumption

Even though there is still some controversy over the effect of greenhouse gases on the environment, the last two statistics are very important for those of us living in urban areas experiencing continuous growth, especially the American Southwest. With our population expansion, aging water and electrical infrastructure, and shrinking landfills, designing and constructing green and sustainable buildings makes practical sense from a utilitarian perspective.

In fact, USGBC data shows that green buildings use 36% less energy, require fewer raw materials, and divert less waste to our landfills. Furthermore, the “increased” cost of green building is only one or two percent more expensive than a conventional building. This minute difference exemplifies the tangible and long-term benefits of sustainable design, primarily due to the fact that green buildings conserve water and electricity. Thus, while they are more expensive to build, green structures will save money by conserving more energy over time.

Another push towards the green build movement is by local governments. More and more municipalities are adopting the USGBC LEED® (Leadership in Energy and Environmental Design) guidelines for new and renovated buildings. In 2006, at the USGBC Greenbuild expo, the Mayor of Denver challenged other major cities to see who can have the most LEED® certified green buildings. They are accomplishing this by offering tax breaks to private corporations and mandating sustainable construction for city-financed projects.

This has led to a dramatic increase in the number of sustainable projects built by LEED® Certified general contractors. However, this growth has not come without challenges. Currently, the following issues are restricting the number of green projects being built:

Increased demand for green products has lead to long lead times

New and unspecified materials are labeled “green” products which are not necessarily certified Building officials are struggling with a steep learning curve on how to evaluate these new products and sustainable building techniques. Despite these difficulties, the USGBC, sustainability advocates, and green building construction management firms are meeting to overcome these challenges.

The LEED® process is constantly under review and continues to adopt the latest codes and products. This includes Standard 189, a new minimum standard for green building. The USGBC is currently developing LEED® 3.0 and working with national code writers to include new products and techniques.

The American Institute of Architects (AIA) has even rolled out a new initiative called “Sustainability 2030,” which at its roots, is looking to design all buildings by the year 2030 as carbon neutral. The USGBC has even initiated the Green Advantage Builders Certification for contractors to certify their knowledge in green building techniques.

So what does green building mean at the end of the day? It’s simple yet profound: Do the right thing for you, the environment, and the next generation. While most companies are concerned with their bottom line, they ought to embrace the idea that energy and water conservation, green building, and the use of “green materials” in construction stands to increase their savings over time while positioning them as a leader in environmental stewardship.

According to the USGBC, we spend 90% of our time indoors. Due to this fact, scientists have identified an increase in allergies, asthma, absenteeism from school, and even work. There have been numerous studies done on post occupancy productivity levels, which have increased within “green” built facilities. Not only does green adaptation result in less sick days taken, but also shows an increase in productivity, job satisfaction, and in the case of schools, better grades.

So, as we positively affect the environment around us with sustainable green construction, we eventually create better health for ourselves.
