5 Times More Effective Bi-Metallic Catalyst

16 May 2009 | Green News | 1 Comment

Researchers from Washington University, lead by Younan Xia, Professor of Biomedical Engineering, has developed a bimetallic catalyst that is almost five  times more efficient than other commercial catalysts.This type of catalysts could enable some cheaper fuel cell technology.The operation principle of this technology is based on the use of platinum and palladium and also using nanotechnology.

What Actually Biofuels Are?

6 May 2009 | Green News | 3 Comments

The mankind has used biomass fuels for heating and cooking since the discovery of fire.Biofuels can appeared as solid, liquid, or gas fuel.Liquid biofuels have been used since the early days of the car industry.By burning biofuels in a furnace, steam is produced which can drive turbines to drive an electric generator.

The discovery and use of fossil fuels like coal, gas and oil, have dramatically reduced the amount of biomass fuel used in the developed world for transport, heat and power.However, biofuels are axpanding recently in all over the world as providing an alternative to imported oil, because they reduce greenhouse gas emissions and increase energy security by providing an alternative to fossil fuels as in automotive transport and in gas turbine.As energy source in developed countries biofuel contribute about 15% of world’s energy requirements.

Biofuels can be produced from any carbon source that can be replenished rapidly as vegetable matter produced by agriculture and forests or from waste materials obtained from industry, commerce and residential homes, including agricultural waste as sugar cane, straw and chicken litter.Biomass is material derived from recently living organisms.It includes plants, animals, and their byproducts.Garden waste and corp residuel are all sources of biomass.By allowing fermentation in landfill sites or in special anaerobic tanks is also possible to produce methane rich gas to be used in gas turbines.

Biofuels are a renewable energy source based on the carbon cycle.Agricultural products specifically grown for biofuel production include corn and soybeans, wheat, sugar beet, sugar cane and palm oil.Biodegradable outputs from industry, agriculture, forestry and households can be used for biofuel production.

Biofuels and other forms of renewable energy aim to be carbon neutral.Therefore, the carbon released during the use of the fuel, through burning to power transport or generate electrical energy is reabsorbed and balanced by the carbon absorbed by new plant growth.Carbon neutral fuels lead to no net increase in atmospheric CO2 which means that global warming does not increase by this process.

Using waste biomass to produce energy can reduce the use of fossil fuels.Simultaneously reduce greenhouse gas emission and reduce pollution.In industrialized countries, biofuels are producing up 5% of electrical energy requirements.

How to Prepare Your Own Biodiesel Fuel at Home

17 April 2009 | Alternative Energy | 3 Comments

You have a car with a diesel engine?  The fuel price is high and the gases emitted pollute the environment? I will present, 2 ways to prepare your own bodiesel fuel at home.
This fuel will work best for your car because it will be clean, diesel engine will go better and will resist more time. This new biodiesel can be made for free if you use the oil remained in your kitchen. So, this fuel can be produced through these two ways:
1) Mixture. Vegetable oil used in your cuisine is quite viscous. This oil will be mixed with diesel or gasoline to become thin and for a good circulation in the car engine. The use of this hybrid fuel, mixed, will lead to a large savings of fossil fuels and reduce polluting emissions from atmosphere. Scientific, has been shown that vehicle motor will survive longer with a biodiesel fuel. Concentration must be 90% vegetable oil and 10% fossil fuel.
2) A second method of saving fuel is based on the fact that we can use only vegetable oil,without mixing it with other substance.For this thing diesel engine should be modified or should be attached another vessel which heat up the oil for greater reliability. Which do you think is more beneficial? Biodiesel fuel or vegetable oil?
