You know, now that I think about it... it's probably not be true anymore, but I bet 3-4 decades ago having a dedicated "sun tea" pitcher rivaled or exceeded kettle ownership, in the US.
("sun tea" is made by sticking a big glass pitcher or jar outside on a warm sunny day, with water and teabags and maybe some citrus slices in it, and waiting for it to become something resembling tea, which you may drink at its natural somewhat-warm temperature, drink over ice, or refrigerate).
Ooh sun tea is so good - it doesnt just resemble it, it can make for a tasty drink. Extraction is a function of temperature and time after all, and lower temperature extractions dissolve less of the more bitter chemicals in plants.
