[Avodah] induction cooking

Gerifa means removal of the source of heat (it is now impossible to adjust
the fire).
This is not possible on our stoves (covering the adjustment knob obviously
does not
constitute removal of the source of heat or make it impossible to adjust the
fire)

Our use of a blech is that it constitutes ketumah
See chayai Adam klal 20 Halacha 12, kisvai r henken pg 21, Imoshe chelek 1
siman 93

covering the knobs does NOT constitute ketumah 
see Imoshe chelek 1 siman 93, be'air Moshe chelek 7 simon 3&4

since Gerifa is not possible if the stove is still on, 
and covering the knobs does NOT constitute ketumah
I do not see a shihiyah/chazorah solution for induction stoves.
