Fuel Cell Electric Vehicle

Fuel Cell Electric Vehicle is an alternative solution to the conventional fossil fuel cars. The FCEV uses fuel cells that chemically convert hydrogen into electricity. The following video shows cars that have been developed by car manufacturers from around the world. The narrator of the video says that the cost of fuel cell electric vehicles has come down by 80 percent. This development is expected by consumers who want to drive eco-friendly cars.


 The main challenge now is building the hydrogen infrastructure that will enable car users to drive their fuel cell electric vehicles where ever they go. Fuel cell has got a lot of potentials to be used as an eco friendly power generator if its hydrogen is produced from renewable energy resources such as solar energy, wind, or hydro-power. Hydrogen can be obtained from the electrolysis of water. Hydrogen has to be stored in liquid form. Electricity is needed to conduct the electrolysis. US car manufacturer General Motors launched its Chevrolet Equinox FCEV in 2008. The car uses hydrogen fuel cell that produces electricity to power its 94 kilowatt (126 horsepower) electric motor. Although most car manufacturers have made several prototypes of FCEVs, the commercial sale of fuel cell electric vehicles, according to their plans, will be realized in 2015. In order for the FCEV to be commericaly viable, its annual production should reach 100,000 units, said Daimler CEO Dieter Zetsche in Speigel Magazine.

Israel's Achievement in Greening the Desert

Israel is a world leader in sustainable development. The Israelis harvest solar energy from their barren lands and create man-made reservoirs to provide water for their farmlands. They also build desalination plants along their coastal region to supply drinking water to the whole population. The Jewish people have even recycled almost all of their sewage water for reuse in agriculture. An Israeli company, Emefcy, develops Microbial Fuel Cell (MFC) system that generates electricity and produce hydrogen while at the same time treat sewage water from food, beverage, pharmaceutical and chemical industries. The company received investment from General Electrics and Conoco Philips for the development of this fuel cell technology that directly harvest electrical energy from sewage water. With the water which they have successfully reclaimed, they are able to water the trees and plants which they plant in the desert using drip irrigation technology. 

Israel's achievement should be seen as an inspiration to all of us to develop our countries and conserve our environment. Desert is not seen as an obstacles but as opportunities in creating better life. Israel develops solar power plants that collect solar energy to generate electricity.

Jewish National Fund is an organization that plays an important role in greening the promised land. JNF collects donations from Jewish communities around the globe and use the money on various projects in Israel including the construction of reservoirs and the planting of trees. In its official website, JNF said that its volunteers have planted more than 240 million trees making Israel as the only country in the world to enter the 21st century with more trees.
The afforestation of the Negev desert is an ambitious project that JNF is going to do in the coming years. JNF plans to build more reservoirs, open farmlands, and bring more settlements to make Israel's land bloom again.
