FoST activities October 2015.jpg

The Foundation for Sustainable Technologies (FoST) does projects in the rural communities of Nepal focusing on empowering women:

All our efforts address the empowerment of women and aim at establishing a sustainable kitchen in the rural communities. We mostly cover four burning issues: (a) energy and environment, (b) water-borne and smoke-borne diseases, (c) indoor air pollution, and (d) income generation. Based on these things, FoST has developed a wide range of environment-friendly, easily-applicable, sustainable technologies for improving the quality of life of rural communities. We are exploring donors' support for continuing and expanding these efforts. In 2013, FoST began a partnership with Solar Cookers International, which provides funds for training in solar cooking, improved cookstoves, briquette-making, and retained-heat cooking technologies to people with little access to biomass fuel.


  • November 2021: Solar lunches prepared - FoST continues to provide meals and other services to local rural communities in Nepal. This latest occasion took place at the Tapasthali home for elderly mothers.
  • January 2020: 

Orientation and live-demonstration of the green energy technologies organized for Seven Women groups from Australia in January 2020.

  • January 2018: FoST demonstrated the green technologies they use in helping to address the humanitarian and environmental concerns facing the local, primarily rural, population in Nepal to touring Australian students in 2017.
  • January 2018: FoST successfully completed two days of exhibitions (3rd and 4th Dec.) on green energy technologies at Nepal's biggest consumer center, Kalimati Vegetable Market in Kathmandu. Their two objectives were to convert energy sources available in the market complex into fuel cakes and tap solar energy for cooking food items and water boiling. They supplied boiled water to the doctors in the free health camp, and tea and snacks to the fifty people involved in the camp, which was jointly organized by the Lions and Leo Clubs, Women Empowerment Group, and Cooperatives.
  • November 2017: A FoST demonstration of solar and sustainable technologies took place on 16 October 2017 for the students and teachers of the Kathmandu International Study Center, Dhobighat, Kathmandu, Nepal.

  • January 2017: Projects for the Lalitpur district - The Foundation for Sustainable Technologies, working with the Solar Cookers International 4th Grant Program, have begun programs in the Devichour VDC and Panauti communities. Previously dependent on biogas and fuelwood. Both are rural villages. The projects are using both Chinese-made parabolic solar cookers and locally produced solar box cookers.

  • January 2017: Parabolic solar cookers demonstrated in BaudhaFoST founder Sanu Kaji Shrestha, with assistance from Kriti, demonstrated and provided parabolic solar cookers to the Tek Chok Ling Nunnery School in Baudha, Nepal. They boiled twelve liters of water and 12kg(26.4lbs) of potatoes in four hours for appreciative nuns. They project the nunnery can expect to save 30-40% of their gas consumption with continued consistent use of the solar cookers.

  • June 2015: Nepalese students discovered ways to cook food and pasteurize water with free solar energy after the earthquake in a demonstration put on by Foundation for Sustainable Technologies with funding from Solar Cookers International.
  • February 2010: FoST founder Sanu Kaji Shrestha attended the Mediterranean Conference on Sustainable Engineering and met with Andreas Fasoulides in Cyprus and discussed on the possible collaboration. Sanu sold a solar CooKit to the participant from Palestine. He also received great interest briquette presses (smallest press just 5 kgs) and briquette stove from the participants from Tufts University. It was a very successful event.

Sanu Kaji Shrestha and FoST promote several types of solar cookers, as well as fuel-*March 2010: Alternative fuel sources were discussed and demonstrated at the recent conference held in Cyprus. Included was a demonstration in the making of a Biomass briquette. An energy efficient and cost-effective fuel source. efficient stoves that burn special briquettes made from agricultural and industrial waste.

  • March 2008: The BBC’s annual World Challenge competition honors individuals and organizations that make a difference through enterprise and innovation at a grassroots level. The top 12 projects were promoted on the television program BBC World and in Newsweek magazine, followed by a public voting period. Solar cooker promoter Sanu Kaji reports that his organization, Foundation for Sustainable Technologies (FoST), was a top three finalist, winning $10,000 for its Cooking Without Gas project. The project was selected over nearly 1,000 others. Kaji Shrestha is grateful for the votes and support from the solar cooking community. In a letter to Solar Cookers International, he wrote, “Part of the credit goes to you and your solar cooking network for lobbying, and untiring support in our efforts.” Congratulations to Kaji Shrestha and FoST for this well-deserved honor!
  • December 2007: FoST of Nepal is one of the 3 finalists in the World Challenge 2007! As runner up FoST has won $10.000 in the global competition organized by BBC World, Shell and Newsweek.
  • October 2007: FoST is among the 12 finalists for the World Challenge 2007. This global competition was set up three years ago by the BBC World, Newsweek and Shell to recognize the innovators of this world. The jury of the World Challenge has chosen FoST as one of the dozen finalists to be filmed for the 2007 series. The popular programmes will be shown on BBC World and featured in Newsweek from October 2007. Over 940 nominations were received which makes reaching the final 12 a great achievement for FoST. The 15 minute documentary film on FoST activities will be released on the BBC World on Saturday 3rd November 2007 and will be repeated as follows: November 3, 2007 at 0930 GMT; November 4, 2007; (not broadcast America or the Middle East) at 0330 GMT, 1330 GMT, and 1830 GMT; November 6, 2007 at 1830 GMT. To vote please go to: (listed under Cooking Without Gas).
  • April 2007: The government of Nepal has adopted a rural energy policy aimed at reducing rural poverty and protecting the environment. The government hopes to encourage local organizations, nongovernmental organizations and cooperatives to develop a variety of new energy sources such as micro hydro, wind and solar. According to FoST director Sanu Kaji Shrestha, the government has recently increased its subsidy for some parabolic-type solar cookers to 4000 rupees per unit, while there also is a 50% subsidy on some solar box cookers. However, he says it is difficult to fulfill the government’s criteria for receiving subsidies. He estimates there are about 2500 solar cookers distributed in rural communities so far.
