Hybrid system makes power from waste coal: "In a new assault on greenhouse gas emissions, Australian scientists have developed a hybrid technology to generate electricity from escaping methane gas and coal mining waste that otherwise would have been released into the atmosphere. .. Neil Phillips, head of the CSIRO's exploration and mining division, told United Press International that, though the technology is not new, no one has ever combined its various aspects to process waste coal and mine gases to produce electricity.  "It is a win on two fronts, in terms of greenhouse gas and waste reduction on the one hand, and cost reduction and revenue for the coal mine, on the other," Phillips said...

Methane, which is trapped in most coal seams and released during mining, has 21 times the greenhouse impact of carbon dioxide. The methane from underground coal mines contributes about 6 percent to Australia's total annual greenhouse emissions. In terms of energy, these emissions represent about 10 percent of the energy value of coal in underground mines.  The issue of coal waste is just as important as vent gas emissions. When it is mined, most coal is a mixture of coal and various soils, and it needs to be washed, resulting in a waste product, which still has a small percentage of coal.  Each of Australia's underground coal mines produces around 800,000 tons of this waste every year. The stockpiled waste not only takes up space -- it also releases methane.  Coal mines spend up to 8 percent of their budgets managing waste coal.  .. . "A big plus is that it could also work at mines which have closed down but still have stockpiles of coal waste."  Japan, for example, has up to 100 million tons of waste, which could be processed in the rotary kiln, he said."

Automated Media System: "AMS's solar systems can provide electrical power to meet the requirements of film/video crews and expeditions."  Ruggedized backpackable battery packs and solar cells are for sale.  6:07:18 PM  permalink  

Global Solar Energy: Producers of integrated systems with flexible thin-film photovoltaic cells.  Among their customers are the military and disaster relief organizations.  2:56:20 PM  permalink  

DSIRE : "The Database of State Incentives for Renewable Energy (DSIRE) is a comprehensive source of information on state, local, utility, and selected federal incentives that promote renewable energy"  2:52:45 PM  permalink  

Biogas fuel cells : "Ascent Power Systems Inc. (APS) and Community Power Corporation (CPC) have announced the successful operation of a solid oxide fuel cell using gasified biomass. In a one-day demonstration, a CPC gasification system and an APS fuel cell were connected and together successfully generated electricity from gas streams derived from pecan shells, wood chips and coconut shells. .. As expected, pure hydrogen produced the highest power level (2.76 Watts) followed by coconut shells (1.97 Watts), pecan shells (1.96 Watts), and wood chips (1.88 Watts).  The three test fuels were selected to demonstrate the robustness of the technology. These fuels are also plentiful, under-utilised waste products from agricultural and forest industries. "  12:42:03 PM  permalink  

Michelin sponsors a challenge each year for "sustainable mobility" attracting efficient cars from various sources.  Among the entrants this year is one from Green Star Products  that achieved 99 miles per gallon under controlled conditions (45 mph constant testing) and over 60 mph in LA traffic.  It uses only a conventional 1994 Geo Metro with a diesel engine and aftermarket lubricants and exhaust modifications.  The fuel was biodiesel.

Bangladesh renewables mapping : UNEP's project to map the solar and wind energy resources of 13 developing countries has begun in Bangladesh.  "The Renewable Energy Research Centre of Dhaka University has taken up a 30-month sub-project (May 2002-October 2004) with the support of the Ministry of Environment and Forests. Experts are convinced that the project, called the Solar and Wind Energy Resource Assessment (SWERA), may prove that the potential for deploying solar panels and wind turbines in these developing countries is far greater than is currently supposed. .. Dr. Subrata Kumar Aditya of the Renewable Research Centre said the national assessment activities in Bangladesh would be completed by the end of 2004."  Maps and reports will be produced and "promoted among the stakeholders and investors in an effort to accelerate deployment, he added.
