Earth Tube Heat Exchanger ETHE is a device that enables transfer of heat from ambient air to deeper layers of soil and vice versa. It uses the known fact that temperature regime in deeper layers of soil say beyond 3m depth remains stable permitting large mass of soil to be used as sink and source of heat.
Arid Area Greenhouse Main challenge for greenhouse technology here is - high levels of solar radiation , high ambient temperatures leading to high cooling loads , severe shortage of water making evaporative cooling less feasible. Area Greenhouse (AAG) was developed to address these challenges.
Dew Harvest Systems Dew occurs in this area frequently and in large amounts but has never before been harvested for human use even though shortage of potable water is chronic. Dew season is eight month long and spans the entire dry part of the year. This makes dew especially useful source of water.
Solar Cafeteria Kutch region has long sun shine hours and high levels of radiation. Centre has developed large solar cooking appliances for use in large homes and schools. These are absorber type, affordable and easy to maintain.
We believe in making sustainable scenarios for tomorrow
