When Coffee Goes High Tech

from the head-for-the-hills dept

Apparently coffee was in need of a jolt of high tech inspiration. Starting in just a few weeks you’ll be able to buy a product that most of you probably never thought was necessary at all: a single serving can of coffee that heats itself. The idea is that you buy the can, and when you’re ready to drink it, you push a button, and it heats itself up. No batteries or electricity needed. Just push the button, let the calcium oxide (yum!) mix with water, and voila, you have a steaming hot cup of joe. Who knew that heating up water was too difficult?

Hey, what about quick heating cars?

It’s -1F (-18C) here, and although my car has the premium windshield washer fluid rated to -30C, it froze solid on the windshield while driving, and it was extremely dangerous. I’d stop, the sludge would melt, but then when I drove, the wind chill would freeze it again. Is there a way to create chemically reactive windshield washer or something?

Nescafe shipped these in the UK a while back.

Around 18 months to two years ago Nescafe in the UK sold a couple of varieties of their coffee in ‘instant-heating’ cans. Just press a button to set off the reaction, wait a minute or two and voila, hot Nescafe coffee wherever you are.

Sadly, it wasn’t great coffee but the cans were useful if you wanted to take a couple in a pack when cycling/hill-walking/biking etc and would end up somewhere without services.

Hot Ice

In an opposite (?) development, a Japanese team discovered that water forms ice crystals inside of carbon nanotubes, even above room temperature (27 C). It’s the first time that ice has been observed at this temperature, without extreme pressure. When the nanotubes were heated to 45C, the ice rapidly evaporated. It may have uses in inkjet printers.
