Design, development and performance evaluation of latent heat storage foot warmers
In this paper, three PCM based foot warmers of cylindrical and rectangular in shape were designed, developed and fabricated to store solar energy during sunshine hours. The stored energy was utilised to warm the feet in the late evening to replace electric heaters. By trial experiment, it was found out that the surface temperature of the storage units of the foot warmer should be between ...

Energy systems in transition: perspectives for the diffusion of small-scale wood pellet heating technology
Promising small-scale wood pellet heating systems with sizable market potentials have started to penetrate the residential heating market in Europe and elsewhere. Despite significant technological progress, cost reduction, improved convenience and reliability, and reduced environmental impact, diffusion of such systems will nonetheless take time. Framework and market conditions, and especially ...

Bioenergy and charcoal production: an alternative option for disposal of combustible municipal wastes
This project explored the possibility of using a CSIRO process to convert green waste (70,000 T/yr) to bioenergy. Tests conducted using CSIRO fluidised bed technique show that these wastes can be successfully converted to charcoal, and that this charcoal is very suitable for use as cooking fuels. The charcoal recovery rates achieved are also acceptable for commercial production and use as ...

Multiple uses for heat exchangers in brewing
There are numerous uses for heat exchangers in breweries, from cooling, pasteurising and fermenting products, through to efficiently dealing with waste streams such as yeast slurry. Compared to other methods of heating, heat exchangers can be much more energy efficient, providing both environmental and economic benefits. One of the first uses of heat exchangers in brewing is for rapidly cooling ...

Focus Bioenergy No 7 2004: Biofuels - heating for the future
Biofuels for heating of homes and properties is rapidly making headway. Environmentally friendly, comfortable and price-worthy small-scale heating with biofuels is done using pellets or briquettes. Changing an oil burner for a pellets burner or replacing electric heating with a pellet-burning stove is often very profitable. It demands less effort than wood firing but somewhat more work than using ...

Renewable Energy - A Key Solution to End Global Warming
Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane and carbon dioxide (CO2) in the atmosphere. These ...

Advocates of Renewable Energy: Be Careful What We Promise
Sixty years ago, nuclear was hyped as a source of energy / electricity that would be “too cheap to meter.” The OPEC oil embargo dashed the western world's dream of bountiful low-cost energy but, when Brian Mulroney was elected a decade later, he terminated Canada's research into renewables because “the energy crisis was over.”That funding cut led to my appointment as head of the Solar Energy ...
