Other innovations from India:

Vertical axis windmill: http://tepp-innovators.blogspot.com/2008/01/wind-turbines-on...
Microsoft, IBM, Cisco all have huge R&D labs in India. And the number of patents coming from them is not insignificant.
Of course, the number of innovations per capita coming out of India is a lot lower vs those coming out of USA or Israel or someone. But India is not a laggard in innovation.
