Training programme on Manufacturing Parabolic Solar Cookers.

Posted: Monday, January 22, 2007 | 12:58:00 PM

Announcement:  "Training programme on Manufacturing Parabolic Solar Cookers and introduction to Renewable Energy Technologies"


Organiser: PRINCE (Promoters & Researchers In Non Conventional Energy), Jankibai Trust, Shamgiri, Agra Road, Deopur, DHULE: 424005


Introduction: PRINCE (Promoters & Researchers In Non Conventional Energy) is a voluntary group working under NGO Jankibai Trust. Details of the organisation can be had from the website www.princeindia.org . Developing new entrepreneurs is the key to promote new renewable energy technologies. Hands on training are the way to develop new manufacturers.


            Parabolic cookers have enormous business potential. With the recent announcement of petroleum minister that the subsidy on cooking gas will be only for the poor, the cost of the LPG domestic cylinder will go up by at least Rs. 200 per cylinder in a year's time. Our experience in Dhule shows that in this town there are more than 100 installations per year without any major advertisements or campaigns. The business can easily go up to 1000 units per year for such a small town. We expect business potential of more than 1000 cookers a year in almost every district. This indicates enormous potential these parabolic cookers, domestic and community models, have in Asian and African continent. Parabolic cookers have following advantages.


  1. Very fast: Parabolic cookers are almost 4 to 6 times faster than conventional box cookers. Most of the boiling dishes are cooked in span of around 20 to 30 minutes. This speed suits many city dwellers.
  2. Cooking starts early: Cooking starts after one hour of Sunrise. In many cases food is ready at 10.00 a.m. This suits office goers and students. This is not feasible in box cookers.
  3. Additional cooking capabilities: Roasting, shallow frying is possible apart from steaming operation. Boiling milk, boiling drinking water etc. can be added advantages.
  4. Taste is great.
  5. Can be used in almost all major states in India. Climate is suitable.
  6. For new manufacturers, Capital investment required is negligible, no gestation period. They can start manufacturing from day 1 after the workshop.


Parabolic cookers can bring in revolutionary changes in Indian market.


Few workshops have been conducted by us for  Renewable Energy Technologies" and were well appreciated by the participants, national level news papers and magazines. We believe in giving hands on training for manufacturing the renewable energy gadgets and necessary follow up after the workshop.            


Background: Free training had been imparted to people approaching PRINCE regarding parabolic cookers. However after such brief training of 2-3 hours, there have been very few trainees turned in to serious manufacturers. It was also observed that after brief training still there have been lots of mistakes committed during manufacturing of this seemingly simplistic product. Hence it was planned to conduct a 3 day workshop covering all these aspects up to last details. Experience of earlier workshops was very encouraging. This is a different kind of workshop than the polished conferences in academic institutes and star hotels. Prospective participants can learn about such workshop and experiences from earlier participants. List of some of the participants who attended last workshop is attached herewith. People are free to contact them and get their views and feedbacks.

Scope of the Workshop: This is a workshop with difference. People who are used to attend different conferences in academic institutions and star hotels will find this workshop very low profile. More stress on practical/workshop training will be given supported with classroom teaching and lecturing. Organisers will like to ensure that all participants will be in a position to manufacture the parabolic cookers after they go back to their place of business. Scope of workshop will include:


1.      All manufacturing details of 'Parabolic Cooker of 1.4 m dia.'. Participants will be involved in manufacturing at least one parabolic cooker from scratch. A manual with all drawings, photographs and instructions will also be given to the participants. Information regarding operation, maintenance will also be practiced and will also be specified in the manual. Participants are expected to conduct all recommended tests on at least one cooker.

2.      All details about policies of central and state governments, test procedures, test centers, registration with Ministry of New and Renewable Energy, subsidies etc. for these cookers.

3.      Costing, material procurement, specifications, marketing strategies etc. for parabolic cookers.

4.      A presentation and lectures on "Entrepreneurship in Renewable Energy". Introduction to other renewable energy technologies. These sessions will set tone for the participants for dos and don'ts in renewable energy profession.

5.      Introduction and basics of solar thermal technologies including different cooking systems, water heating systems, air heating systems, solar vegetable dryers etc. Special emphasis will be given on following issues.

a.       Manufacturing aspects of Solar Vegetable-Fruit dryer for food processing applications. Demonstrations on Solar dryers/air heating system will be held.

b.      Different solar water heating systems, criteria for selection of system, capacity calculations. Detailing on installation, commissioning, plumbing, selection of material for pipe and insulation etc.
