Researchers: Ocean Algae Biofuels Might Prove To Be A Sustainable Energy Source; 'Encouraging Results'

Manhattan, Kansas -- Research by two Kansas State University scientists could help with the large-scale cultivation and manufacturing of oil-rich algae in oceans for biofuel.
K-State's Zhijian "Z.J." Pei, associate professor of industrial and manufacturing systems engineering, and Wenqiao "Wayne" Yuan, assistant professor of biological and agricultural engineering, have received a $98,560 Small Grant for Exploratory Research from the National Science Foundation to study solid carriers for manufacturing algae biofuels in the ocean.
Algae are a diverse and simple group of organisms that live in or near water. Certain algal species are high in oil content that could be converted into such fuels as biodiesel, according to Pei and Yuan. Algae also have several environmentally-friendly advantages over corn or other plants used for biofuels, including not needing soil or fresh water to grow.
Pei and Yuan plan to identify attributes of algae and properties of materials that enable growth of certain algae species on solid carriers. Solid carriers float on the water surface for algae to attach to and grow on.
"Not all materials are equally suitable to make these carriers," Yuan said. "Some materials are better for algal attachment and growth than others, and we will be identifying what those 'good' materials are."
The project could help with the design of major equipment for manufacturing algae biofuels from the ocean, including solid carriers, in-the-ocean algae harvesting equipment and oil extraction machines, Pei said.
"This research aims to develop a cost-effective process for growing algae on solid carriers in the ocean for biofuel manufacturing," he said. "If successful, it will greatly benefit the energy security of the United States, as well as society in general."
The research will be conducted with a two-step approach.
"Selected algae species will be grown on solid carriers in a simulated ocean environment and will be evaluated for their ability to attach to solid carriers and grow in seawater, their biomass productivity, and their oil content," Pei said. "Top-ranked species in step one will be selected to test the performance of several carrier materials, including natural organic, synthetic organic and inorganic materials, with the same evaluation parameters as in step one."
Pei said the properties of the highly-ranked carriers also will be analyzed.
Yuan, who has studied biodiesel for several years, said the major problem with making the fuel has been finding sustainable oil and fat sources.
"Algae seems to be the only promising sustainable oil source for biodiesel production," he said. "In my lab, we have several different projects involving algae and we have been trying different ways to grow it. We have already obtained some encouraging results."
Pei said the project also will have an educational benefit, with K-State College of Engineering graduate and undergraduate students to be involved in the multidisciplinary research.

Newly installed Solar Panel at Kita Ayase subway station
Today, when I take the morning train from Kita Ayase station, I was so suprise with the new panel on the wall showing the electricity generated using the solar panel newly installed on the roof of the station. The electric will be used for the lighting and escalator in the station. It is one of the effort from Tokyo Metro (subway company) to reduce the CO2 emission.

The Koshigaya-Laketown - Eco and Flood Disaster Prevention New Town
The Koshigaya-Laketown - Eco and Flood Disaster Prevention New Town
The Koshigaya Laketown is developed along the JR Train line. It has been desinated as the first 20% CO2 reduction Town development project in Japan.

Solar Heat Water storage is installed on the roof
The Koshigaya Laketown JR station is located at the center of the town and can easily access to Tokyo. It to be made as the main transport system for the new town.

Eco Life Fair 2008
Eco Life Fair 2008
Different weight of the CO2 emission per person is loaded in the beg. People can take the beg to compare the different weight for Japanese, Chinese and American. It is a good way to teach people about how much difference of the CO2 they emitted.

The food court of Eco Life Fair was also very special. The container for food need to be rent from the special counter. After finishing the meal, the customer need to return the contain and you can get the refund. Waste seperation is needed during the disposal of the waste.
Real experiment of the normal and energy saving light bulb. On the left is normal light bulb and right is the energy saving ligth. The normal ligth is now cost electric of 214 yen, while the energy saving bulb just 48 yen. It is 4 times more saving by changing to new one. Toshiba is announcing that they will stop the production of normal light bulb very soon.

The children in the city has less chance to play with the toys made from natural wood. It is a good campaign to promote the natural toys. In Japan, there is a lot of replanted forest lack of proper maintainance and being left as the price is higher than the imported woods. There is still a large area of trees need to be cut down for replantation, but due to the lack of demand, and man power for the wood industry, it is now left with no proper maintainance and now become a problem for erosion. They called the poor forest as "Green desert".
