Harvesting Electrical Power from Waste Heat Using Stirling Engine to Lessen Energy Crisis in Rural Areas of Bangladesh
Harvesting Electrical Power from Waste Heat Using Stirling Engine to Lessen Energy Crisis in Rural Areas of Bangladesh
Energy crisis is on of the most critical infrastructure constraints on Bangladesh’s economic growth. With 78% of the population currently having access to electricity mainly through Government efforts, there is still much to do for the remaining population, especially for rural people. About 80% of total energy produced in mud stoves used for cooking purpose in rural areas of Bangladesh is wasted for the inefficiency of the system. Stirling engine (SE) can be used to harvest electrical power from this waste heat. In this research overall scenario of energy crisis in Bangladesh has been diagnosed. Field inspection has been performed to estimate the waste heat scenario and electricity demand of rural households. Under these considerations a SE with momental volume of 3.0595×10-3 m3 at 100 rpm engine frequency can generate 47 watt of electrical power. A prototype was constructed in association with Western Marine Services Limited, Bangladesh.

Generation of Electricity Using Cow Urine
Generation of Electricity Using Cow Urine
This project presents a renewable source of energy; energy from cow urine that can produce electricity by electrolytic conduction. To assess the effectiveness of the source we developed a prototype that can hold five liters of fresh urine as electrolyte. Imitating a car battery we used similar and equal number of electrode. Afterwards we measured the performance of the source with varying loads and observed its outputs.
