Biogas is increasingly popular as a source ofrenewable energy. To use it further, a research team at the Harvard School of Engineering and Applied Sciences are conducting research to utilize methane on a laptop fuel cell and battery.
A team led by Shriram Ramanathan has focused on solid oxide fuel cell types (SOFC) that rely on methane produced from biogas and certainly does not use platinum anymore.
In addition, they also developed a micro-scale SOFC working at a temperature of 500 degrees Celsius. According to Ramanathan, if SOFC can operate at temperatures 300-500 ° C temperature range, it will open more implementations, such as in vehicles and portable electronic devices. In fact, still thinks, that they develop SOFC will no longer depend on pure hydrogen as fuel, but a variety of other fuels, as well as replace batteries for laptops and other portable electronic devices.
Mobile electronic devices that give priority to renewable energy as a source of energy is leading to greater levels of commercialization. In addition to Samsung, Nokia, LG mobile phones from manufacturers, there are many other producers are also beginning to make the concept of eco-friendly products.

8.2 billion U.S. dollars in South Korea prepared to construct 500 offshore wind turbines. Several large companies such as Hyundai Heavy Industries and Daewoo Shipbuilding and Marine Engineering will be involved in the project.
As quoted by AFP, the wind turbine farm would be near the area Buan and Yeonggwang. To 500 turbines that will generate 2.5 gigawatts of electricity.
The South Korean government will be the coordinator of projects worth 8.2 billion U.S. dollars and provides funds 29 billion won, or about 26.2 million U.S. dollars. The rest is funded by private investors who joined in it.
The Korean government considers the field of offshore wind turbines as a promising potential, given the country’s land area is small and nuisance to surrounding residents and environmental impact is relatively small compared with the field of wind turbines built on a vast land.
Building a park on the roof building is one of the innovative and effective ways to improve environmental quality while reducing the impact of global warming. 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.
Germany, the country that leading adopters of solar cell technology to generate electricity GigaWatt 14 at the end of 2010, set a target to produce the overall supply of electricity from renewable energy sources in 2050.
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%.
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.
There are some people who can apply the breakthrough made by scientists at the Yissum Research Development Company Ltd., A company whose function is to commercialize technology research Hebrews University in Jerusalem.
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.
Do not want left behind from Toyota, Honda plans to launch the two-door sports car Honda CR-Z hybrid. 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.
One thing that you can consider to make your house more elegant is the color of your wall paint outdoors.
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.
