Never seen it on an UK fridge -- Those who want slavery should have the grace to name it by its proper name. They must face the full meaning of that which they are advocating or condoning; the full, exact, specific meaning of collectivism, of its logical implications, of the principles upon which it is based, and of the ultimate consequences to which these principles will lead. They must face it, then decide whether this is what they want or not. Ayn Rand.

I thought they were using induction motors, driven by an inverter which
controls the frequency and the voltage. Generating three-phase AC
current and using three-phase motors.

Generating three-phase AC > current and using three-phase motors. Three-phase AC motors are three-phase because the phases provide the "rotating magnetic field" to produce rotational motion on the armature. So the motor can just be windings and on-off switches. But if you drive the coils of a DC motor with a proper controller that "sequences" the coils properly so you get the 'rotating magnetic field', you can get any speed you desire, and extreme torque even at startup. Same style of motors that are used on electric cars now. Also the same style motor driver in all the little 80mm CPU fans sitting inside all our computers for cooling purposes.

Wildfires - or even the threat of wildfires - can and will shut down transmission lines, and car accidents can knock out utility poles. Thunderstorms - and short-circuits caused by traffic accidents knocking out poles - cause transformers to explode. And many of the poles here in town are very old and are getting replaced, one at a time (requiring multiple 12-hour shut-offs in local neighborhoods). -- Lars Poulsen - an old geek in Santa Barbara, California

Doesn't Natural Gas[TM] i.e. municipal methane piped in to reidences - require electric pumps somewhere in the distribution network? At my house a have 14kW NaturalGas-powered generator for when the power drops out. If the failure is due to an earthquake, I expect that the gas will also be shut off. At which point I will be looking for propane tanks, and the conversion kit to change the motor from methane to propane (a different pressure regulator ?) I cannot do that ahead of time, because I do not have a code-compliant way to maintain or store the propane tanks. Lars Poulsen - an old geek in Santa Barbara, California

Same. I cannot recall any instance of a gas distribution failure. Electricity, however, those outages recur with regularity. Although my specific area has become more reliable over time such that I now see a full on outage maybe every year or two instead of every time a thunderstom rolls through in August. > BTW gas stoves (at least basic cooktops) also run without electricity > (although you might have to dig up some matches if you depend on a > mains-driven spark to light it).

Just need those matches for ignition source. > Too bad the Powers that Be are trying to eliminate gas appliances. I > guess we need to save all that gas for LNG sales overseas. They claim it is "climate related" in that doing so reduces pollution output. Hard to tell, without auditing their donations carefully, where the real source of their desire to ban them is arriving from.
