Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room temperature water, cutting energy use by up to 75%.
Why the fuck would I want a room-temp espresso?
"Although the researchers say their new system could be relatively easily developed into an automatic coffee machine for home users, the biggest opportunity is likely to be for large-scale commercial producers of coffee-based drink."
They say it in the article what it is for...
When hot days and you need to wait for it to cool down and add ice. All those Starbucks frappucinos with this tech will save the world.
Hot day? What's that?
It’s like a hot dog.
Cold brew
You got 19 upvotes (as I see it) for having repeated word for word (or copy-pasted) what they say in the subtitle. An interesting phenomenon in itself.
Yes. He gave us the missing information from the clickbait-title. In this way he was making the subtitle here available, and i didn't needed to click a link to a random website too read it.
In the end i was was clicking the link because the subtitle sounded interesting. With just the title i probably would not read it. And then i controlled if he cited it correctly. And because it was the same i gave an upvote to confirm to others that the subtitle is correct
