On goes the Ethanol juggernaut

Vinod Khosla, an esteemed Silicon Valley VC and a champion of cleaner energy
invested in an India-based startup

The investment highlights a few important points:

1) The continuation of seamless cross-border investments between U.S and India.
2) Growing importance of Ethanol in our energy landscape.
3) Maturing of the Indian market with respect to deal structure for VC investments -- the articles mentions the usage of "preferential shares". I'm not sure if this is the same as "preferred stock" as used in the U.S, but will try and research.
