energy saving ,gas saving rice cooker

My experiment with energy saving ,gas saving rice cooker.,just for fun. 

I tried using an induction stove friendly pressure cooker and the steamer and lid from rice cooker for this experiment today. As induction stove consumes very much less power than rice cooker and its timer helps to cut off power. I cooked rice and tovar dal in the bottom container and placed potato, kadalaparuppu and Pudalangai in the steamer. Adjusted the power level to just boil the water in the vessel and set the time for 45 minutes. All were cooked and I could remove the potato at the right stage of tenderness.
