Fuel from cellulose has been around from a long time, back to WWII.  It works, but it&#x27;s always been a marginal technology economically.  Around 2012, lots of companies seemed to be building plants, and some of them even started up.[1]  But few seem to break even.<p>It&#x27;s frustrating that this doesn&#x27;t work well, since most plants are powered by agricultural waste (stalks, cobs, etc.) that is already being produced and just has to be collected.  However, it&#x27;s good to know this can be done, since someday, oil will run out.<p>[1] <a href="http:&#x2F;&#x2F;www.renewableenergymagazine.com&#x2F;article&#x2F;abengoa-celebrates-first-commercialscale-next-generation-biofuel-20141020" rel="nofollow">http:&#x2F;&#x2F;www.renewableenergymagazine.com&#x2F;article&#x2F;abengoa-celeb...</a>
