I have an interesting idea to those who spend much time being lost in the kitchen.
Never-ending queues of frying pans, pots, all-possible cauldrons, and these all make you feel exhausted at the end of the day. This is the case especially with big families.
Thus my idea is as follows.
I offer to invent special device fitted inside, on the bottom of the cooking vessel (frying pan, saucepan or something like that) so it would be able to regulate the required temperature itself. It in its turn will lighten the work of housewives, it won't be necessary to run to and fro to gas-stove to reduce or increase the fire. Imagine! You will be able to easily boil milk without ugly spots of the spilt milk on the gas-stove afterwards.
