Appropriate Technology

The isolation and remoteness of the Ladakh Region makes centralized energy distribution models, neither feasible nor viable. Extreme weather conditions with a prolonged winter season, when temperature falls below zero degree Celsius, remoteness and a crucial scarcity of natural sources of energy like “fuel wood” renders life difficult in the region. Therefore, it is not at all difficult to understand the importance of a daily energy need for the Ladakhi people. Various programs of government agencies for the provision of clean energy sources like electricity and natural gas have not reached majority of Ladakhi people, which has, hence, deprived remote villages of basic need facilities. This is the prime reason which led LEDeG to bring in intervention which aimed at providing a platform for Community Based Services (CBS), so that the Basic Need Services (BNS) could be facilitated. The first step towards this aim was to encourage a decentralized model of energy production and distribution, using local renewable resources. These are mainly sunlight and water resources which are found abundantly in the region. LEDeG has worked on a wide variety of appropriate technologies by carrying out adaptive research and feasibility studies vis-à-vis local conditions, needs and requirements. Presently, LEDeG has in-house expertise in propagation of various appropriate technologies, such as Micro Hydroelectric Power Units, solar water heating systems, Trombe wall technology, solar ovens, solar parabolic reflector cookers (both, for individual families and communities), hydraulic ram pumps, improved water mills and solar photovoltaic lanterns and household units. The main emphasis of LEDeG is on the ‘Decentralisation of Energy and Water Supplies’ (DEWAS) which fits the requirements and needs in the socio-cultural and geographic context of Ladakh.

Auto Climate Control system for Green House

This is a demonstration project which is scalable, this project is developed using the Arduino Platform this project uses a Arduino nano which is coupled with a 12 Volt 2-channel relay system which can control heavy A.C loads, which means that a Heating system can be used in the winters and the programmable board can control the heating module efficiently while monitoring the temperature of the green house, and also in summers a ventilation system to throw excess moisture away from the green house.

SOLAR RANTAK (Flour mill)

Concept and design note on Solar Flour Mill:

Now over the years weather pattern is changing incredibly at a very fast rate, ladakh is getting irregular rainfall and the glaciers are melting at a very high rate, we have to look for other sources to support the traditional way of living.

And this project is conceptualised and designed to support the traditional flour mill, by changing the driving source of the mill from water to solar.

Problem Description

  • Conventional grid powered flour mills have huge running cost
  • Power Grid is either not available in all parts or is highly irregular
  • Present day mills use concrete grinding wheels which has led to the depletion of flour nutrient quality
  • Due to scarcity of running water hydro-powered mills have become almost unfeasible

Improved Butter Churner

Changing whole milk to butter is a process of transforming a fat-in-water  emulsion – milk to a water-in-fat emulsion butter. Whole milk is a dilute emulsion of tiny fat globules surrounded by lipoprotein membranes that keep the fat globules separate from one another.

Butter is made from cream that has been separated from whole milk and then cooled; fat droplets clump more easily when hard rather than soft. However, making good butter also depends upon other factors, such as the fat content of the cream and its acidity.

The machine present in the market right now has limited functionality with two button system for forward and reverse direction of spin, and works on external battery, so LEDeG came up with a new machine which is automatic forward and reverse spin directions and is capable of working on solar as well as normal electric current. design modifications are going on at our A.T Workshop. soon it will be introduced in the local market.
