Biofuels
According to the National Renewable Energy Laboratory [NREL] (see
http://www.nrel.gov/learning/re_biofuels.html):
“Unlike other renewable energy sources, biomass can be converted
directly into liquid fuels, called “biofuels” to help meet transportation fuel
needs. The two most common types of biofuels are ethanol and
biodiesel.”
“...[Ethanol] is made by fermenting any biomass high in carbohydrates
through a process similar to beer brewing. Today ethanol is made from
starches and sugars, but NREL scientists are developing technology to
allow it to be made from cellulose and…
Scientific Name Corallium rubrum L.
Family (Phylum Colelenterata)
Used Part Corals are the calcareous skeletons of the minute marine organisms of polyps (Phylum, Coelenterata) and used part is calcareous shell.
Distribution Area They are common throughout the tropical seas, and are regular components of the fauna of coral reefs. The Milleporesare common near Singapore and are mostly white, buff or yellowish in colour, while the Stylastersare often of pink red or purple hue.
Common Uses…
Current commercial and non-commercial biomass use for energy is estimated at between 20 and 60 EJ/a representing about 6 to 17 percent of the world primary energy. Most of the biomass is used in developing countries where it is likely to account for roughly one third of primary energy. As a comparison, the share of primary energy provided by biomass in industrialized countries is small and is estimated at about 3 percent or less.
Global land availability estimates for energy crop production vary widely between 350 and 950 million hectares ( Alexandratos , 1995). An energy…
Utilization of biomass for energy and industry allows a significant quantity of hydrocarbons to be consumed without increasing the CO2 content of the atmosphere and thus makes a positive contribution to the Greenhouse effect and to the problems of “global change” as occurs in both industrialized and developing countries. Further the advantages from utilization of biomass include: liquid fuels produced from biomass contain no sulfur, thus avoiding SO2 emissions and also reducing emission of N0x. The production of compost as a soil conditioner avoids deterioration of soil and…
Arbor energy? No, they're not smoking plants, they're powering circuits with them. It turns out that there is electricity in trees, in small but measurable quantities, and it's enough for University of Washington researchers to run an electronic circuit.
A study last year from the Massachusetts Institute of Technology found that plants generate a voltage of up to 200 millivolts when one electrode is placed in a plant and the other in the surrounding soil. Those researchers have since started a company developing forest sensors that exploit this new power source.

Biofuel have a great potential but turnig food into biofuel is not correct way instead work on the petroplants, local plants and search for non edible oil plants like Jatropha etcas source of biofuel and improve their agrotechnology of production extraction purification and conversion. Invite people to suggest extraction procedures for petrocrops and optimise yield of Jatropha curcas.
Renewable Energy sources (RES) include small hydro project, Biomass, Gasifier, Biomass power, urban and Industrial water power and wind energy.
30 percent of the primary energy consumption in India still comes from non-commercial energy sources like firewood, agricultural waste and dung cakes. In 2000, the primary source of cooking energy was firewood and woodchips or dung cakes for 86 percent of rural household. In urban areas as well more than 20 percent of all households rely mainly on firewood and chips. Only 5 percent of the households in rural areas and 44 percent…
A sample survey was conducted in a cluster of 4 villages.10 families from each village were questioned for the survey. The main objective of the survey was to do a scenario analysis of the fuel used for cooking purpose and it’s interrelation with the background of the family in order to assess the following:
· Current pattern of fuel use
· Economic Status of the families
· Awareness level of people about Jatropha
· Readiness to use Jatropha as an alternative fuel
The four villages in which the survey was conducted were:
Papra
Chota Kakrana
Mahasingh ka Bans
Ismailpur

Greening of wastelands:
It is proposed to carryout the programme of greening of wastelands encompassing three components:
1/ Exchange on innovative experiences from farmers in semi arid conditions in Rajasthan and exchange of information with Mali and more generally with the Sahara and Sahel Observatory based in Tunis.
Part 1. Exchange on innovative experiences from farmers in semi arid conditions in Rajasthan and Mali and more generally with the Sahara and Sahel Observatory based in Tunis.
There are many innovative…
"Jatropha Is Not Competing with Existing Food Crops to Produce Biodiesel”
The biofuel market is growing, and with it the development of certain crops to meet energy needs. One of which is Jatropha, a plant that is gaining importance in this sector. Ian Graham the Deputy Director of the Centre for Novel Agricultural Products and professor at the University of York in the UK answers scitizens questions.
A new kind of biofuel is being produced derived from a plant called Jatropha. Can you explain a little about this plant?
Jatropha is bush that grows in the warm regions of the world as it is…
