Tefal has an amazing kettle that can make hot water hot in 3 seconds flat! It's called the QuickCup and it sucks the water through a filter and a coil that heats the water as it's drawn through. The end result is that you heat only the water you need.

It can also be used cold as well to just filter the water, again in 3 seconds flat. Only the water you need, right away.

I wish they sold this in the U.S., but it appears this is a UK-only thing. Can't even really import it thanks to the different electrical outlets. Maybe they have a gadget like this in the U.S.? Leave a comment and let me know.
