Energy saving Pot

Once I have heard of this energy saving pot frm Mr L. This pot is more for making soup. Basically you do not need to waste electricity brewing the herbal soup/ red bean soup for 3-4 hrs. What you need to do is to cook the soup for like 50 mins using the gas and put it into the energy saving pot. No electricity nothing...and the soup remains warm, just like you used the electricity to cook it for hrs. So how much you have save the earth, the $ you spent on the electricity bills..mmmmm think about it :P

Cheers,
