gas saver net

This is another of those products that you can hardly find on the racks of department stores.

Some call it the gas saver net, or gas energy saver, it's basically a net made of metal wires arranged like bicycle spokes. All you have to do is to place it on your gas hob, and it is supposed to help you save gas. From the description it says the net can increase the burning temperature from 660-800 degrees celsius to 1000-1200 degrees celsius; save on 38% gas; reduce carbon monoxide from 0.18% to 0.026%; cook food 14% faster.

Seriously I have no idea if all these claims are true, but I can say that it really helps to prevent the flame from being blown out and leading to gas leak. How so? Well the net is already heated till red hot, so if the flame got blown out, the gas from the hob can still be ignited by the hot metal net. If I seriously want to test its efficiency, I will have to do a little experiment boiling water and timing it.

Now here is a little clip I took with the net, before my phone almost got melted cos it's black and absorbs thermal radiation. Argh my eyes!
