I love Kevin Kelly’s Cool Tools — not only because it hearkens back to the Whole Earth Catalog (from which it is more or less descended) which I loved, but for its own virtues: good, clear reviews of things I actually can use. Not everything, of course, but periodically I do buy things it reviews and have never been disappointed.
The latest is the IngenuiTEA Teapot. Making one cup of tea is as easy as it could possibly be. Boil water; put loose tea in the Ingenuitea; when tea is ready, put the device on top of a cup; the contact with the rim of the cup opens the valve and tea flows into the cup, leaving the loose leaves behind.
I love it. Cool Tools links to Amazon, which sells it with tea. It can be bought cheaper without the tea from Cooking.com.
It is an example of a simple, straightforward technology that does something simply and extremely well. Would that more of the technology that we use day in and day out were as functional.
