EcoGeek has an interesting article explaining how advances in nanotechnology can lead to the creation of a kettle that boils faster. The advance is significant not just because it could help consumers and businesses save money and time by bringing water to a boil faster, but because it suggests that a variety of other products—such as solar cells and catalysts—might also become radically more effective.
Of course, before many of these advances can be adopted people will need to unlearn the idea that a “watched pot never boils.”
