When I’m making tea, I can often find myself boiling the water, searching for teabags etc and then absent-mindedly flicking the kettle switch back to ‘on’ without really needing to reboil.
Today’s invention is therefore a kettle whose bimetallic switch will only allow the water to be heated if it is, say, >5 degrees below 100C.
At higher temperatures, the tea won’t actually suffer noticeably taste-wise at all.
Thus, if the water temperature is 98C and you flick the kettle on, instead of wasting a huge amount of energy, the kettle will emit satisfying recorded noises of water boiling.
