Every year Electrolux's Design Lab competition throws up some amazing inventions, but sadly most never make it further than the designer's CAD program. This year's winner is a nifty portable magnetic induction heater for heating up pots, pans and mugs.
It could save money in the home, by cutting down on electricity or gas when firing up the ol' stove, and could have nice repercussions for the environment too. Working just like a magnetic induction stove, only smaller, it can be placed on the side of something like a pot or pan to heat up the contents. Sensors would be able to recognize what type of food is being cooked, adjusting the temperature and time accordingly.
