[Greenbuilding] Induction cooking

[Stephen]

The ability to distribute heat is a function of heat conduction properties
of the material in question. Aluminum is a much better conductor of heat
than iron or steel. If an aluminum pan has a disc of "ferrous material" I
would guess it is to enable induction heating, only.

  Most higher QUALITY aluminum pots have a disc on the bottom that contains
ferrous metals to better evenly distribute the heat. Those that don't
are--as I and others have pointed out--too cheap to waste your money on.
>From a sustainability standpoint, they're a total waste of resources.  (And
then there are the arguments against using aluminum which have also been
pointed out.)

Yes, absolutely correct! .087kwh and .150kwh.


Thanks for the correction

   hum,
   your off with your math by a factor thousand.


   0,150 kWh
   0,087 kWh

   There is hardly any energy efficiency benefit versus natural gas
cooking.

   And for  induction cooking you need special pans .

Electric stovetop versus induction:


.5 litre  water to a boil.


Kenmore electric stove:


1200 watt element/60 minute * 7.5 minute = 150kwh


Salton model 1081 induction cooker from Costco ($65) :


1310 watt / 60 minute * 4 minute = 87 kwh


A great way to help flatten the curve.
