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.

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

This seems very interesting, at least from a pure coffee nerd standpoint and what it could mean for improving espresso brewing in general. However, I'm going through the research paper, and am a bit skeptical of the energy savings angle, especially considering the many variables with espresso machine in terms of how they heat and brew (single vs dual boilers, heat exchangers vs dippers, spring lever machines vs pump…

It seems like most of the energy associated with espresso would not come from the brewing step, but rather from the cultivation, processing, and transportation of the beans. Similarly, the brewing energy is likely 100% electrified, and could be supplied by carbon neutral sources, while the energy from earlier in the process is more likely to be from fossil fuels.

Earlier quoted context omitted.

Every ultrasound device makes sound, sometimes a lot of sound, because it's vibrating all of the materials, liquids, and air around it.

So does every piece of baryonic matter in the universe, in which case I am proud to be an ultrasound device.

Affirming the consequent fallacy.

"Ultrasound machines vibrate everything around them therefore make sound" does not imply "I vibrate everything around me therefore make ultrasound."

"room temperature espresso" was the first thing I thought of - espresso is meant to be drunk hot, right away. If you let a good shot cool off and compare it to a bad shot you're not going to notice the difference as much because you made them both worse by letting them sit and cool. For industrial processes it probably doesn't matter - look at how nescafe is manufactured.

I wonder if this process would work if the water were replaced with milk. Milk would degrade at high temperature, but this (at least in bulk) is at room temperature.

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

Very interesting for industrial use, that’s for sure. For domestic use, in the home of somebody whose coffee snobbery is dialled to 11, I need far more information. What beans were they using, freshness, etc? (Edit: Campos coffee… not on my shopping list that’s for sure…) How did they control for extraction method differences to maximise output quality for all brew methods? (Edit: TDS and EY) Were the “regular” coffe…

> Did the espresso drinks have milk in them? I felt a great disturbance in Italy, as if millions of voices suddenly cried out in terror and were suddenly silenced. Espresso does not have milk. Macchiato , is an espresso based drink with milk. Edit: it's bad form to change your message after-the-fact to remove the thing that was quoted.

There are much greater sins against Italian coffee than dropping a word that doesn't change the meaning. "Espresso drink" vs. "Espresso-based drink"? come on.

For those sensitive souls I'd think they'd be more worried about "Expresso","Frappacino", "Puppacino", Starbucks, and 20oz "venti" lattes.

Not in general, but I think some people would be ok, and that's all that's needed for that question to be interesting.
