defrosting

The defrosting is driven by sensors, but rarely happens more than e.g.

In a typical microwave the thinner areas actually start cooking rather than simply defrosting when operating at 30% power.

Both are time savers, in the sense of microwave saves time defrosting and calculator saves time calculating vs human.

You'll want clear mode management, temperature management when defrosting meat, pre-heating and convection when cooking a whole chicken etc.

So the water keeps filling any small cracks, freezing and expanding, then defrosting and refilling the now bigger cracks.

My (old) fridge/freezer used about 80 watts when averaged over time (peak is 300W when self-defrosting).

Even defrosting it by running cold water over it in the sink won't get it ready to cook in time.

Many heat pumps already have a mechanism for deliberately wasting energy for defrosting the coils.

And the defrosting/downloading charge was acceptable at effectively 2.5 months worth of storage.

The windshield defrosting situation was also a non issue for me.

My fridge is 30 years old and unless you count periodic cleaning and defrosting as maintenance it has had no maintenance at all in that period.

Microwave is mainly used for defrosting or warming up leftovers.

I've lost count of the number of times i've seen tesla drivers "defrosting" their door handles.

Defrosting sucks profoundly, also the frost build=up makes opening drawers hard and prone to damage.
