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

Fix uncertainty is a massive issue when "driving blind." The 400Hz systems are the most critical (same with aircraft). When you cannot see, the precision of the instruments becomes all that matters. Luckily GPS allows for fix resets, but once submerged the ESGNs are "it."

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

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

In my time it was SINS with a few ESGMs being retrofitted.  ESGN was the next class.  Unless we were in the Med tracking LORAN, BRN-8 was our best fix - been awhile, but I think we were looking at somewhere around 8 minutes mast exposure.
 
I taught Trident Nav but never went out with it 

turn off a lamp somewhere, to offset the deficit.

 
Beagle and BobF at work,  but who are the other two?

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..

The big solar farms use molten salts for storage.  I wonder how practical that would be scaled down to residential size?
 
And seriously, we all know caves stay steady temp year round.  Why aren't we living in caves?  Yes, I'm aware that some of are mistaken for cave dwellers from time to time.
 
Why aren't solar water heaters more wide spread? 

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

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

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?
