Another anti-logging activist killed in Brazil. Mongabay.com October 28, 2011 Another opponent of logging in the Brazilian Amazon was gunned down in the state of Pará, reports AFP.
Joao Chupel Primo, 55, was shot and killed Saturday after receiving death threats due to his outspoken advocacy against illegal clearing of rainforests in Itaituba, a region in southeastern Pará. The Pastoral Land Commission says that Primo was shot in the head as he worked in a machine shop. Primo became the eighth illegal logging activist killed since May in Pará and Rondonia. Few of the perpetrators have been brought to justice. Conflict over land in the Brazilian Amazon is common.
Tensions are especially high in the Brazilian Amazon due to high commodity prices, which boost land values and make land-grabbing — and associated deforestation — more profitable. Murders tied to land disputes in rural Brazil, cumulative total of 383 since 2000. Related articles. Energy. Energy.
CHINA. China's charm offensive. Hybrid vehicle. A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle.[2] The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.
However, other mechanisms to capture and utilize energy are included. Power[edit] Power sources for hybrid vehicles include: Vehicle type[edit] New hybrid airships prepare to take flight. New high-tech hybrids promise a new era for airships Marrying lift of helium with the aerodynamic lift of an airplane transforms possibilities for airships Hybrids could help transport heavy cargo long distances and help humanitarian aid efforts London (CNN) -- If you thought airships were old hat, think again.
A new breed of hybrid airships are preparing to take off raising hopes that a 21st century fleet can finally succeed the zeppelins of yesteryear. The difference is radical says Michael Stewart, chief executive of World SkyCat Ltd, a British company which has designed a new air vehicle, the SkyLiner.

Hybrid Transport - ELTON. The main drawback of transit city buses and trucks, shunt locomotives, and diesel-trains in railways is the unjustifiably high consumption of fuel, due to an inefficient mode of operation (e.g. frequent accelerations and stops, idling) with considerable environmental combustion product emissions.
Similarly, the operation of open-pit dump trucks, gantry cranes and certain types of sea-going vessels when maneuvering in ports is inefficient. The conversion of engines like this to a hybrid power supply combining the internal combustion engine (ICE) with an electric motor and energy storage device seems to be the best way of upgrading vehicles such as this. The full power of the engine in heavy-duty vehicles such as transit city buses or shunt locomotives is only realized during acceleration.
Hybrid Vehicles. Advantages Usually integrate a gasoline internal combustion engine (ICE), an electric motor-generator and battery pack, arranged to operate in parallel, series or series-parallel.
Have similar performance as conventional ICE vehicles Disadvantages Battery replacement costs are high Hybrid electric vehicles (HEVs) typically integrate an internal combustion engine (ICE), an electric motor, a generator and a battery pack. Generally, hybrid vehicles equipped with ICEs use lean burning gasoline, but hybrid diesel systems are currently under development. Toyota unveils dual mode hybrid fuel transport. A futuristic, eco-friendly transit system will be prototyped by Toyota as part of the on-site transportation for the 2005 World Expo in Aichi, Japan.
The new system aims to show nature's wisdom and examples of a new global society in action. The ' Toyota Z-Capsule' is a dual mode train/bus fuel cell hybrid that offers an amazing step forward in the evolution of motor vehicles. It looks a little like an i-Mac crossed with a bus, but its sleek, ergonomic design is based on nature, with a panoramic window display and streamlined comfort and use of space offsetting it's fuel efficiency. The futuristic transporter operates on motors powered by high-pressure hydrogen-supplied fuel cells and a nickel-metal hydride secondary battery. Unlike gasoline- and diesel-fueled vehicles, it does not emit carbon dioxide or other toxic substances during operation and is highly energy-efficient, as well as quiet to run.
Futuristic Motorbikes: Hybrid Individual Transport for China in 2020. Electricity from biomass – BIOS BIOENERGIESYTEME – Steam Turbine. The steam boiler consists of the evaporator unit, the superheater and the economiser which are usually arranged in a four-pass design.
In addition, some manufacturers implement an additional combustion air preheater in the flue gas downstream the economiser whereas others use steam or hot water for combustion air preheating. The feed water of the water steam cycle is heated in the feed water economiser which is installed downstream the superheater, to a temperature close to the boiling point. Urban Ecology Australia - Biomass Electricity. Discussion Electricity can produced from biomass such as plantation fuelwood, which can be burned to run steam-turbine electricity generators, or turned into gas or methanol before firing a turbine.
A fuelwood plantation can be a source timber and aromatic oils as well as fuelwood, and can also be used to control salinity. Biomass electricity is potentially greenhouse neutral, and can have low impact on natural ecosystems if the fuelwood is derived from plantations that host biodiversity. Biofuels vs. Biomass Electricity. A study published today in Science concludes that, on average, using biomass to produce electricity is 80 percent more efficient than transforming the biomass into biofuel.
In addition, the electricity option would be twice as effective at reducing greenhouse-gas emissions. The results imply that investment in an ethanol infrastructure, even if based on more efficient cellulosic processes, may prove misguided. The study was done by a collaboration between researchers at Stanford University, the Carnegie Institute of Science, and the University of California, Merced. There’s also the potential, according to the study, of capturing and storing the carbon dioxide emissions from power plants that use switchgrass, wood chips, and other biomass materials as fuel–an option that doesn’t exist for burning ethanol.
The researchers based their findings on scenarios developed under the Biofuel Analysis Meta-Model (EBAMM) created at the University of California, Berkeley. EIA - Biomass for Electricity Generation. This paper examines issues affecting the uses of biomass for electricity generation. The methodology used in the National Energy Modeling System to account for various types of biomass is discussed, and the underlying assumptions are explained. Electricity from Biomass. The term "biomass" encompasses diverse fuels derived from timber, agriculture and food processing wastes or from fuel crops that are specifically grown or reserved for electricity generation. Biomass fuel can also include sewage sludge and animal manure. Some biomass fuels are derived from trees. Given the capacity of trees to regenerate, these fuels are considered renewable. Burning crop residues, sewage or manure - all wastes that are continually generated by society -- to generate electricity may offer environmental benefits in the form of preserving precious landfill space OR may be grown and harvested in ways that cause environmental harm.
At present, most biomass power plants burn lumber, agricultural or construction/demolition wood wastes. In terms of capacity, biomass power plants represent the second largest amount of renewable energy in the nation. What are the environmental impacts? Environmental Concerns. Green initiatives. Green.
