I’m always boiling more water in the kettle than I need. This wastes huge amounts of both water and energy.

Today’s invention provides a fairly simple way to limit this bad habit. An inlet pipe to a small cistern is sealed against a kitchen’s cold water tap. The tap is left in the open position but water can only flow from the tap when a handle is depressed: as in normal bathroom cistern operation.

The difference here is that the internal ballcock is capable of being set by an external dial so as to allow water to flow through in multiples of 1 cupful.

You can thus place the kettle beneath the outlet, dial up ‘four cups’ and only that amount flows into the kettle. Much easier than squinting at a meniscus through a steamy window in the kettle wall as you attempt to hold the whole thing in mid air.
