The failed Range Fuels wood-to-ethanol factory in southeastern Georgia that sucked up $65 million in federal and state tax dollars was sold Tuesday for pennies on the dollar to another bio-fuel maker with equally grand plans to transform the alternative energy world.

LanzaTech, a New Zealand-based biofuel company, paid $5.1 million for the plant in Soperton. Its main financial backer: Vinod Khosla, a California entrepreneur who also bankrolled Range Fuels, and helped secure its government loans, before Range went bust last year.
