All told, the company spent more than $600 million. In its brief time in operation, it generated $2.3 million in revenue; when it filed for bankruptcy it listed assets of $58.3 million. ... The next generation of biofuels, made from plants and biowaste (so-called cellulosic materials), which have lower carbon emissions than oil, were a particular passion. Khosla invested hundreds of millions of dollars in about a dozen biofuel and biochemical companies. ... His ambitions were audacious. Khosla declared “a war on oil.” As he wrote in 2006, “I believe we can replace most of our gasoline needs in 25 years with biomass.” He dismissed incumbent energy companies in a 2007 interview as not investing heavily in biofuels because they weren’t “used to innovation and the rate of innovation we are likely to see in this business.” ... Unlike most failed startups, KiOR hasn’t just shut its doors and disappeared into oblivion. Today recriminations, investigations, and litigation continue to surround it. The Securities and Exchange Commission has been examining whether the company made false statements, including on a critical point: the yield of its biofuel (the amount that can be made per ton of wood chips). Two KiOR executives and Khosla himself are also facing a class action suit alleging that company executives misled investors about production volumes and yield. ... The state of Mississippi is also suing Khosla and key KiOR executives on similar grounds, claiming they hoodwinked the state to obtain a $75 million loan.
