Bangalore A low-cost, battery-operated electrocardiogram has pretty much been the mascot for General Electric's frugal engineering in India, finding a lucrative market in advanced countries.

Now, its wind turbine, optimised for India's low wind conditions, is also on its way to playing a role in the reverse innovation game. The electrocardiogram, introduced in India four years ago, now sells in about 70 countries, along with other locally designed products, such as an incubator and phototherapy systems.
