Have you ever imagined paying less than $2.00 USD per gallon at the pump again? Have you ever imagined seeing a field full of prickly pear cactus? Not only is the prickly pear cactus (nopalito) often an edible part of your favorite Mexican cuisine, but could be finding its way to your fuel tank while putting a smile on your face at the same time.
One start-up company in Mexico has developed a process for turning prickly pear cactus juice into fuel costing around $1.81 per gallon ($0.40 per liter).
In a recent Scientific American article, the use of CAM plants is extensively discussed for their potential for developing new biofuels, used for both vehicles and powering electrical generation plants.
