Electricity use

If you're sampling at twice the rate you're clearly using twice the electricity, but the results are only 20 - 40% better...

That's what my experience with 60hz vs 400hz power supplies tells me.

You're delusional!  EVERYONE knows that 400Hz is 6.666666666666666666666666666666.7 times better than 60Hz!
 
why ELSE would they put it on airplanes????

Because that's a harmonic of the resonant frequency of the wings, which makes them easier to flap and thus save energy...
 
Do you know nothing?

yes, but if you flap them at 192kHz you get even more efficiency, so why stop at 400?

You want to risk burning out the dilithium crystals?

Of course knot!  I protect them with my Sound Blaster!!!

400Hz is used for high precision AC gear (SONAR suites in submarines run on them as well). Sorta sucks about the DC aspect of computers (but for the sake of the "3 millionth post" this is definitely debatable!)

Submarines ... that's where my experience with 400hz was.  Also Beryllium and "mass unbalance modulation", IIRC.
 
Improperly aligned 400hz synchros were sure whiney

Does it take more electricity to record at higher sample rates?

No. 
 
But during the summer it does take significantly more electricity for the air conditioning to cool things down from blowhards going on and on about their higher sample rates.

I am an EE and work on fighter aircraft.  400Hz is the only AC they use (they use several different voltages of DC).
 
We also deal with Beryllium in some of our aircraft equipment.

ESGs, by chance?

I'm not sure what an ESG is, so I'm sure I don't work on those! 

My primary job deals with a 25VDC power supply.

I tend to sync my sample rate to that of the lady offering those tiny hot dog pieces at CostCo.

OH MY GOSH!  THE HORROR!!
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
You go to Costco????????

For some items...
 

is that enough?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
cause you're full of it!!!

I love Costco.  But they seriously need to add some chocolate to those sample stations.

turn off a lamp somewhere, to offset the deficit.

been off grid solar for the last 20 years-apparently-the inverter smooths out the sinewave and stabilises the voltage-no blackouts,no brownouts,no problems when the neighbour fires up the 3phase welder etc and no ragged brown crap coming down the line.
now-Tesla expect to build 1 billion of their Power Wall batteries and Mr Musk believes that we can be responsible for our own electricity-wow-what a novel idea.
Coal fired power plants versus the Sun.
You cant buy or sell solar radiation so there`s no profit and little altruism.
storage has always been the downside but that is all about to change.
brave new world?
maybe..

Why aren't solar water heaters more wide spread?
 
even the best systems are currently only efficient for a few months a year and unless you live in Flagstaff or similar and have a massive array,you need instantaneous gas heating backup,especially if you are off-grid.
-solar water temp right now is 19c,outside temp 8c but fortunately we have 300 year old tech-a water jacket on the back of the wood heater although it is illegally plumbed as finding someone to integrate the solar water/wood water/gas water was impossible as it would void warranties and fire regulations etc,blah blah 
 
the main impediment IMHO is that once you sell the solar water/solar power infrastructure there is,apart from some maintenance and the obvious life of any system,no further revenue stream for power suppliers who rely on base load fossil burning generation and we have one of the biggest reserves of dirty brown coal in the world.
we also have the highest quality yellow cake uranium we sell to everyone else but don't think is safe enough for us-that is way more complicated than solar/wind/wave/bio generation.
don`t get me started or I will bore you all with my views on apathy and not turning the light off and leaving things on standby when you are finished.
they have justed granted exploration leases for brown coal 60 k from here so will need to dust off the organic hand woven beanie made from the abandoned nest of an endangered Leadbeaters Possum and once again join the others on the picket line.
don`t get me started...........
cheers

No. 

Well, actually it does.. not so that you would notice though these days, but as every single time a gate switches from 0 to 1, or 1 to 0 it consumes energy then higher sampling rates would have higher power consumption...

Isn't that what I said in the first reply?
