Re: Hot water...
Those "instant boiling water" taps are convenient but also bloody wasteful, continually keeping water up to temperature in the off chance that you are in and want a cup of tea.
Until the free energy revolution arrives (what happened to the unmetered energy promised by the atomic age :p ) I'll keep boiling a kettle. (And yes sometimes too much water in it, the outlaws have a 1 cup kettle which is even more efficient)
