You wake up, guests come over, there's the afternoon tea break, and post-dinner treat. Everyone in the UK uses an electric kettle. Over and over again. It wastes a huge amount of heat - and energy. Both technologies exist already: electric kettles and thermos insulators...so why not combine the two and save on time, money and energy.
Often we find ourselves doing repetitive actions without question. I love playing with ideas about how our daily experiences can be improved. It's such a simple step, to insulate a kettle, but would make a huge difference.
