Insulated Solar Electric Cooker – ISEC (2023 Fall)
The Challenge
Indoor air pollution from traditional wood-burning stoves is a major health hazard, causing 24,000 deaths in Nepal every year. Additionally, many rural families face an energy crisis due to their over-dependence on expensive, imported cooking fuels like LPG.
Our Solution
A team of students improved the Insulated Solar Electric Cooker (ISEC), adding a stirring mechanism and a momo steamer to better suit Nepalese cooking habits. This frugal innovation uses solar panels to cook food efficiently without producing any harmful smoke.
How It Works
The research also explored a new “flux generator” method using rotating magnets to create induction heat, which could significantly reduce cooking times. The ISEC uses thick rockwool insulation to achieve 95% thermal efficiency and retain heat for long periods.
The Outcome
By using free, renewable energy, the ISEC eliminates the risk of smoke inhalation and reduces a family’s fuel costs. This project helps rural and off-grid households achieve energy independence while protecting their respiratory health.
