Energy
Researchers at the City College of New York say they have developed a new way to generate power for planes and automobiles using piezoelectrics. Piezoelectrics convert the kinetic energy of motion into electricity. The researchers will present their concept later this month at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics.
About a half-inch by one inch in size, these devices could be mounted on the roof or tail of a car or on an airplane fuselage where they would vibrate inside a flow, producing an output voltage. The power generated would…
It is estimated that biomass covers currently up to 15% of the world energy demand, almost 1/3 of all energy consumption in the Less-Developed Countries. This rate was over the last years rather constant, with increasing overall demand bioenergy consumption increased in absolute terms.
Table 1 : World Energy Consumption pattern 1997 (ref 1)
Biomass Share
Total World 9.6 Bio TOE 1-1.5 Bio TOE 11-15%
Asia 2.3 Bio TOE 0.6-0.8 Bio TOE >30%
Africa 0.4 Bio TOE 0.2-0.27 Bio TOE >50%
Lat. America 0.4 Bio TOE
Table 1 makes it clear that the proportion of bioenergy is particularly…

Summary:
Biomass contributes a significant share of global primary energy consumption and its importance is likely to increase in future world energy scenarios. Current biomass use, although not sustainable in some cases, replaces fossil fuel consumption and results in avoided CO2 emissions,…

Summary:
The 21st century may be remembered as a turning point in energy. Meeting the energy demands of our growing population - while addressing CO2 reduction - remain the central issue for businesses, governments, and individuals alike. Biofuels can be produced in large quantities and have multiple…
wind energy and climate change
During 11th plan Government of India has proposed 78,500 MW capacity development out of which renewable energy is to account for 14000 MW including 10,000 MW of wind energy. During 2035 it is proposed that country will need 800,000 MW of electricity of which only 3,50,000 MW could be met by conventional energy sources and rest of it i.e. 4,50,000 could be obtained from renewable energy sources only out of which wind power will have major share. However some the concerns about system stability were raised which included voltage flicker due to wind…

Biomass currently supplies about a third of the developing countries’ energy varying from about 90% in countries like Uganda, Rawanda and Tanzania, to 45 percent in India, 30 percent in China and Brazil and 10-15 percent in Mexico and South Africa. The crucial questions are whether the two billion or more people who are…
Now we get to corn. It seems that everything having to do with generating chemical energy, like methane and alcohol, making plastics is lumped under the moniker “biomass.”
The fun with biomass is to follow the money. Take biodiesel. We just grow soybeans, rapeseed, sunflowers – whatever you want to make oil out of, press them and run diesel engines with it. Diesel engines are great machines and happy burning just about any fuel – hydrogen included.
First start with natural gas to make hydrogen to make ammonia to make fertilizer. Then plant soybeans,…
Biomass utilization for food, fuels and chemicals.
Biomass :
Biomass refers to all the matter that can be obtained from photosynthesis. Most vegetable species use solar energy to create sugars from carbon dioxide and water.They store this energy in the form of glucose or starch molecules, oleaginous, cellulose, and lignocellulose.
Biomass appears to be an attractive feedstock for three main reasons. First, it is a renewable resource that could be sustainably developed in the future. Second, it appears to have formidably positive environmental properties, notably the recycling of carbon in the…

ABSTRACT : Concern over the growing levels of greenhouse gases and climate change has been building up for the last
decade. Any measure or project reducing the release of greenhouse gases would get a “credit”, regardless of the location of
such measure or project since climate is a…
