With all the push towards lower power consumption in home appliances, like new standards for standby power consumption of televisions and DVD players, why hasn't anyone bothered trying to put some thermal insulation around an electric kettle ? According to
Apparently we spend %11.6 of our electricity (and hence CO2 emissions) on powering standby circuits inside household appliances.
I mean, I measured an electric kettle that boils 2 cups of water (typical amount of water remaining after one pours a cup of tea) consumes about 200kJ, multiply by 5 times a day and you have 1MJ/day of wasted heat. Thats equal to running a 60W lamp for 5hrs a day. A cheap Chinese stainless steel vacuum insulated hot water flask can hold water at near boiling for several hours. So why hasn't anyone put these two inventions together ?
