I think that you are correct.  Modern CO and smoke detectors are
required to brick themselves when a specified time in service is
exceeded, to force replacement.

The ones with a primary lithium battery and 10 year rated lifetimes
are great, but they don\'t seem to last for 10 years.

So far, I have not had this happen.  I write the service date on the
bottom of the unit before installation, so I\'d know.

Wow, OCD or what?

Please don\'t tell me you\'re as bad as one of my relatives who writes the

Useful if you want to know whether LR44 cells that cost £2 for 10 are

Yes. Although it can be done. I worked at an observatory where there
was a massive flywheel generator combo to provide enough energy to
stow all the telescopes to safe zenith position in the event of a
mains failure.

The thing was a brute and had to be aligned so that it would not hit
anything within 2 miles if it ever broke free of its bearings.

Today they tend to go for batteries and an inverter with diesel
backup, but there was a period in the late 1960\'s when big fast
flywheels were the method of choice for emergency power in remote
observatories.

That matches roughly what we had at the CERN Proton Synchrotron.
There was this massive motor-generator set to smooth over the
pulsing of the main bending magnets. These days, it\'s done with
six or seven shipping container-sized boxes full of capacitors
and a building full of power electronics.

How long did that take? Minutes? Batteries would be more efficient and
don\'t have to be kept spinning.

Probably about a quarter of an hour. I don\'t ever recall seeing it do
that. It saved us from brownouts a lot more often and kept the computer
happy. A Marconi Myriad didn\'t like having its power removed suddenly.

Flywheels are good for massive peak powers, like megagauss magnets and
rail guns. But not good for storing much energy.

The flywheel also provided regular supply conditioning as its much more
common benefit. Most mains brownouts and glitches seldom lasted more
than a couple of minutes before power came back on again.

The people with the biggest consuming kit in the 1960\'s were Prof
Pippard\'s group studying Fermi surfaces with a 2MW magnet and a direct
line to the national grid to warn them when they were about to switch it
on (always late at night when electricity prices were cheaper)!

Superconducting magnets pretty much did away with that - out evolved.

The thing was a brute and had to be aligned so that it would not hit
anything within 2 miles if it ever broke free of its bearings.

Today they tend to go for batteries and an inverter with diesel backup,
but there was a period in the late 1960\'s when big fast flywheels were
the method of choice for emergency power in remote observatories.

Swiss have had gyro powered buses for a long while.

https://en.wikipedia.org/wiki/Gyrobus

Edges of the gyro flywheels tend to be moving uncomfortably fast.

And the radial stresses are necessarily near fly-apart levels.

I think it was mostly lead inside a tungsten sleeve overwound with high
tensile steel a bit like a tyre would be. I never saw inside it. I was
warned that if it ever made funny noises to leave the building immediately.

The maximum safe spin rate was used as an exam question not long after
it was first brought into service (why waste a good calculation?).

I remember as a teenager reading about a \"home-flywheel\" concept in one of the local Electronics Magazines (must\'ve been during the oil crisis of the 70s).

Several tonnes of mass in a sealed, evacuated enclosure with magnetic bearings. Required an excavation below the house the size of a basement (which are very rare in Australia). Needless to say none were ever marketed/built!.

They must not have been in an emergency department, lately, if they

seen the inside of one lately, either..

Parked on a gurney in a hallway for two or three days is what you can
expect if you\'re sick enough to be admitted but not critically ill, much
less a \"room\", even at many suburban hospitals these days.

You\'d likely get better sleep on a quiet park bench.

I had a very nice visit to the ER at SF General, where the people were
great. I got three CT scans until they were happy with the images. I
have them around here somewhere. I traveled a lot back and forth for
the imaging and didn\'t see any gurneys parked in hallways.

Then I got a beautiful private room with a view for two days. Not bad
for a medicaire patient in a public hospital.

Zuckerberg\'s wife is an MD at SF General, so he bought the hospital
for her. It\'s the only major-trauma center in town.

Experiences differ depending on where you are. I recently accompanied my brother to the ER at the insistence of his PCP. Arrived around noon after we left the PCP\'s office. We had to wait in the \'over flow\' room. Four hrs after arrival they took my brother for blood sample urine sample, and vitals. Six hours after that, he was seen by an ER doc and then told to wait in the waiting room till they determined if they had a bed for him. Three hours after that (we are up to 13 hrs) they \'found\' a bed for him in the hallway of the ER area. So as I leave through the ER at approximately 2AM, the waiting room looked like a homeless shelter. I asked the nurse what gives and she wryly said it is the poors\' health care system.....And this was in a hospital in the more \'upscale\' area of the city, which is close to the more undesirable parts of the city.
A day later they found a semiprivate room for him where he stayed for 2 days...and then at the insistence of one of the attendies and his PCP, he was moved to \'a better floor\' and a private room...

Like a lot of industries, healthcare in the US will be using Covid as an
excuse for the next 20 years as to why they can\'t provide basic
first-world levels of service.

Meanwhile management salaries will continue to only go up

Try NiMH.  They last 10 years no matter how quick it uses them.

I\'d need a charger for them*. And I only use them in low consumption
devices like clocks. I\'ve got rechargeable AAs and AAAs and a charger
for them, but I don\'t use them in things like remote controls as the
batteries last a year or more.

But the rechargeables last 10 years.

At a lower voltage: 1.2 vs 1.5.  That\'s enough to make the LCD readout
of a clock nearly unreadable, too dim. On some devices, it triggers the
low battery warning.

I know, I use rechargeables.

I haven\'t seen a device that can\'t handle the lower voltage for about 15
years.  And that was a mechanical clock.  Fucking terrible on any kind
of battery, as it slowed down as the voltage changed.
