A Pakistani Villager builds an Ox-Driven tube-well
A village from the same village of Dr Abdus Salam from Pakistan has built a tube-well that doesn't require electricity or solar power. What it requires is the pull given by an Ox. Talk about Old is Gold huh! :)
I build this ram-pump of parts laying round in my back yard I only bought the one non-return valve
Keep a lookout on my channel for the DIY project of how to build one of these Ram-pumps .I will do a detail design!

The pressure of population has reduced Pakistan's forests to a few scrubby trees way out on the horizon, causing extreme fuel shortages in rural areas. To compensate for this, about three quarters of the billion tons of animals manure produced annually is burned for heating or cooking. Anyone who has visited pakistan will remember the acrid smell of burning manure in rural areas. This however causes tremendous medical problems. The acrid smoke leads to endemic eye disease, and the drying manure is a perfect breeding ground for flies of all types. The manure would also go a long way to improving the quality of the soil and hence increasing the harvest if these valuable minerals were returned to it instead of going up in smoke.
INTRODUCTION OF BIO GAS AND OUR PLANT
Biogas originates from bacteria in the process of bio-degradation of organic material under anaerobic (without air) conditions. In the absence of oxygen, anaerobic bacteria decompose organic matter and produce a gas mainly composed of methane (60%) and carbon dioxide called biogas. This gas can be compared to natural gas which is more than 80% methane.
National bio gas program offer fix dom (6 m3 to 18 m3 ) small and medium bio gas plants is generally used for cooking and lighting purposes. Large units (25 m3 ,35 m3 , 50 m3, 100m3,200m3 )or more mega units produce this gas in large quantities and can be used for hotels, bakers, peter engines (tube wells) and generators for power generation.
National bio gas program's plants convert livestock manure into biogas and slurry (the fermented manure). This technology is feasible for small holders with livestock producing minimum 25 kg manure per day. This manure has to be collectable to mix it with water and feed it into the plant. Toilets can be connected. Another precondition is the temperature that affects the fermentation process. With an optimum at 36 C° the technology especially applies for those living in a (sub) tropical climate. This makes the technology for small holders in developing countries often suitable.
Our high quality biogas plant needs minimum maintenance costs and can produce gas for at least 20 years without major problems and re-investments. For the user, biogas provides clean cooking energy, reduces indoor air pollution and reduces the time needed for traditional biomass collection, especially for women and children. The slurry is a clean organic fertilizer that potentially increases agricultural productivity.
Our fixed-dome bio gas plant (Ideal for Pakistan) The costs of a fixed-dome biogas plant are relatively low. It is simple as no moving parts exist. There are also no rusting steel parts and hence a long life of the plant (20 years or more) can be expected. The plant is constructed underground, protecting it from physical damage and saving space. While the underground digester is protected from low temperatures at night and during cold seasons, sunshine and warm seasons take longer to heat up the digester. No day/night fluctuations of temperature in the digester positively influence the bacteriological processes. The construction of fixed dome plants is labor-intensive, thus creating local employment. Fixed-dome plants are not easy to build. They should only be built where construction can be supervised by experienced biogas technicians. Otherwise plants may not be gas-tight (porosity and cracks).
FERMENTATION IN BIO GAS PLANT
There are two basic types of organic decomposition that can occur: aerobic (in the presence of oxygen), and anaerobic (in the absence of oxygen) decomposition. All organic material, both animal and vegetable can be broken down by these two processes, but the products of decomposition will be quite different in the two cases. Aerobic decomposition (fermentation) will produce carbon dioxide, ammonia and some other gases in small quantities, heat in large quantities and a final product that can be used as a fertilizer. Anaerobic decomposition will produce methane, carbon dioxide, some hydrogen and other gases in traces, very little heat and a final product with a higher nitrogen content than is produced by aerobic fermentation.
Anaerobic decomposition is a two-stage process as specific bacteria feed on certain organic materials. In the first stage, acidic bacteria dismantle the complex organic molecules into peptides, glycerol, alcohol and the simpler sugars. When these compounds have been produced in sufficient quantities, a second type of bacteria starts to convert these simpler compounds into methane. These methane producing bacteria are particularly influenced by the ambient conditions, which can slow or halt the process completely if they do not lie within a fairly narrow band.
