Plant Fueled: Grassroots Biofuel in
Pittsburgh (2008). Short Documentary about
Biofuels in Pittsburgh. Biofuel (if
cultivated, then also called agrofuel or
agrifuel) can be broadly defined as solid,
liquid, or gas fuel consisting of, or derived
from recently dead biological material, most
commonly plants. This distinguishes it from
fossil fuel, which is derived from long dead
biological material. Biofuel can be
theoretically produced from any (biological)
carbon source. The most common by far is
photosynthetic plants that capture solar
energy. Many different plants and
plant-derived materials are used for biofuel
manufacture. Biofuels are used globally and
biofuel industries are expanding in Europe,
Asia and the Americas. The most common use
for biofuels is as liquid fuels for
automotive transport. The use of renewable
biofuels provides increased independence from
petroleum and enhances energy security. There
are various current issues with biofuel
production and use, which are presently being
discussed in the popular media and scientific
journals. These include: the effect of
moderating oil prices, the "food vs fuel"
debate, carbon emissions levels, sustainable
biofuel production, deforestation and soil
erosion, impact on water resources, human
rights issues, poverty reduction potential,
biofuel prices, energy balance and
efficiency, and centralised versus
decentralised production models. One of the
greatest technical challenges is to develop
ways to convert biomass energy specifically
to liquid fuels for transportation. To
achieve this, the two most common strategies
are: 1. To grow sugar crops (sugar cane, and
sugar beet), or starch (corn/maize), and then
use yeast fermentation to produce ethanol
(ethyl alcohol). 2. To grow plants that
(naturally) produce oils, such as oil palm,
soybean, algae, or jatropha. When these oils
are heated, their viscosity is reduced, and
they can be burned directly in a diesel
engine, or the oils can be chemically
processed to produce fuels such as biodiesel.
Wood and its byproducts can be converted into
biofuels such as woodgas, methanol or ethanol
fuel. Some researchers are working to improve
these processes. Biomass is material derived
from recently living organisms. This includes
plants, animals and their by-products. For
example, manure, garden waste and crop
residues are all sources of biomass. It is a
renewable energy source based on the carbon
cycle, unlike other natural resources such as
petroleum, coal, and nuclear fuels. Animal
waste is a persistent and unavoidable
pollutant produced primarily by the animals
housed in industrial sized farms. Researchers
from Washington University have figured out a
way to turn manure into magic. In April 2008
with the help of imaging technology they
noticed that vigorous mixing helps
microorganisms turn farm waste into
alternative energy. Providing farmers with a
simple way to treat their waste and convert
it into energy. There are also agricultural
products specifically grown for biofuel
production include corn, switchgrass, and
soybeans, primarily in the United States;
rapeseed, wheat and sugar beet primarily in
Europe; sugar cane in Brazil; palm oil and
miscanthus in South-East Asia; sorghum and
cassava in China; and jatropha in India. Hemp
has also been proven to work as a biofuel.
Biodegradable outputs from industry,
agriculture, forestry and households can be
used for biofuel production, either using
anaerobic digestion to produce biogas, or
using second generation biofuels; examples
include straw, timber, manure, rice husks,
sewage, and food waste. The use of biomass
fuels can therefore contribute to waste
management as well as fuel security and help
to prevent climate change, though alone they
are not a comprehensive solution to these
problems.

Here's my 16th amv. This one took me over a
month to finish, but I love how it turned out
so it was worth the time.
This is a mixed amv that uses 10 different
anime. If you haven't figured it out yet this
amv is very bloody and the theme for it is
hatred. Hope its not too bloody for you guys
xD
well enjoy ^^

| Anthrax - fueled - live @ Npa- France |
 |
I really loved this band in the period "Sound
of white noise" - "We've come for you all and
period". The music was modern and powerfull
and John Bush was not the typical heavy metal
singer. Today Anthrax sound like an old heavy
metal band...sad
