Dear abinash.gupta003@gmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
We appreciate if students do such projects with their own ideas.
With reference to the above question, yes we can store food without electricity in Zeer pots.
In ancient, it used to preserve food mostly in summers.
Now, you can use this idea and prepare the project basis your own research and understanding.
