“Due to the fuel crisis in Nepal now we don’t get gas for cooking. I just wanted to ask you if you have some idea regarding building a solar cooker. I did some search in google but I could not come up with a concrete idea. And yeah I have a methane gas chamber in my house. Do you have some idea to improve that as well because its not enough to cook 2 meals. Thank you.” Prateek
“Toilets, water, depleted tropical soils, and refrigeration are four of the myriad challenges of the developing world. Small fruit, vegetable, and meat sellers lose considerable stock to the sweltering heat. Farmers’ fields and drinking water get flooded by water contaminated with human feces. The water taps stop running for weeks at a time forcing people to drink fetid water. Consumers buy dubious products and suffer increased rates of sickness to top off the other challenges of poverty. Another challenge is processed goods, necessities such as soap or washing basins, cause money from a poor area to flow out to large foreign businesses. All of these challenges can be met by a community store.
Turn household wastes (human wastes and food scraps) into clean burning biogas with $300-$400? (waiting for current price list) Biotech biogas plants, or make one yourself. Biotech also sells waste to electricity plants. Payback period is only 2-3 years. They now mass produce their biogas plants out of PVC and aim to sell one to every household in India as a standard commodity.
Our blog focuses on low cost, sustainable ways of building homes with local resources. It’s equally exciting and practical learning about alternatives to costly centralized grid systems (electrical, gas, sewer, water) that tend to lock people into the system and make them vulnerable to price controls. Biogas is one of many renewable energy systems that provide greater independence at very low cost. Biogas is especially practical in rural areas where running power and gas lines are cost prohibitive. Distributed systems such as biogas and other biofuels, solar water heaters, wood stoves, solar ovens, etc. located at or near the source typically keep functioning during times of emergencies. When a whole city or region is without power, water and sewer during a blizzard, your family can be safe and snug.
“Jean Pain (1930–1981) was a French innovator who developed a compost-based bioenergy system that produced 100% of his energy needs. He heated water to 60 degrees celsius at a rate of 4 litres a minute which he used for washing and heating. He also distilled enough methane to run an electricity generator, cooking elements, and power his truck. This method of creating usable energy from composting materials has come to be known as Jean Pain Composting, or the Jean Pain Method.
