Attention! Attention! I just found out that planes in New Zealand can fly with a 50-50 mix of fuel and jatropha oil (a poisonous plant). Here is the website for those of you out there that want to read the story: http://in.news.yahoo.com/137/20090101/736/tnl-poison-shrub-oil-powers-new-zealand.html
Here in Illinois we use corn and fuel to navigate our cars.
Any other ideas out there in blogville know how to save fuel oil for another day, year, century? Would like to hear your response.
