As I glance at my (checks notes) $200 power bill in San Diego apartment used entirely to run 3 ceiling fans and a box fan, I’m getting curious about all the ways power consumption can be reduced. No AC, LED lights, all gas appliances. I am going to switch over to a bunch of DC tower fans which claim to cut energy usage substantially. I wish more appliances would just switch to DC motors.

Were you running all those fans on high 24/7? Three 150W ceiling fans and a 50W box fan? $200 / $0.50 = 400kWh / 720 hours = 556 watts of load on average, which is more power than I use to run a 1-ton AC unit on auto. BLDC motors are fairly common these days in HVAC equipment, speed control is much easier and they’re more efficient. > I am going to switch over to a bunch of DC tower fans which claim to cut energy usa…

Perfect guess! They have a lot of DC fan options

No air conditioning? In San Diego? Most people find that climate control makes up the vast majority of their power bill.

Depends on which part of the county you’re in but within a few miles of the coast you can go no AC for all but 4-6 weeks if you don’t mind a few warm afternoons

You think people who drink espresso would be ok with drinking milk? Also a majority of humans are lactose intolerant.

The majority of people that drink espresso drink it with milk.

Have you lost your mind 8)

Espresso is so named because you "express" the brew from the beans and you do that with water because water is pretty neutral in flavour, is not poisonous and has quite a few other properties that we have evolved to exploit or live with.

Milk is a weird liquid associated with mammals nursing infants. We humans have evolved to be somewhat lactose tolerant post infancy which is rare in animalia (1)

Given that we are using the Italian word - espresso - then let's use their definition. If you add milk then you have a latte or a cappuccino or an americano con latte, a flat white or whatever.

Real weirdos try to milk oats. I've tried but I can't find their teats.

The majority of Americans that drink espresso drink it with milk.

Really? The Last time I was in an American office, there didn't seem to be any milk around. They had an unrefrigerated bottle of "creamer" next to the coffee machine, but I was too scared to try it. I'm still not sure what it is, or how I'm supposed to use it.

....surely you must have heard of macchiato(espresso with a dash of foamed milk) at some point in your life?

And lactose free milk is a thing, for those of us who can't have lactose anymore.

It’s intravenous. You should try it!

My dad was stationed on a submarine in the navy and he and a few others used to dump their laundry in the ultra-sonic cleaner normally used to clean engine parts. Said it did a great job....

Submarines didn’t always have laundry services. For a 90-day trip, the crew would bring six uniforms and rotate them daily. Shower was one minute of water once a week. Everyone smoked tobacco all the time, everywhere.
