How can cactus（仙人掌）help the world？It can provide a new kind of sustainable fuel（可持續(xù)燃料）.Nopalimex，a company in Mexico，has made one of the world's first cactus-powered factories.The idea came to Sosa in Nopalimex when he was looking for ways to save money for his food factory.He now powers his factory with cactus gas（氣體）.The cost to produce the gas is half the cost of electricity.
Soon，the gas produced by Nopalimex will also be used in cars.Nopalimex's gas is made by using the prickly pear（刺梨），a kind of cactus.To make the gas，the prickly pear is mixed together with manure（肥料）.Then the mixture produces the gas that can be used as fuel.
Why cactus？Fuel can be made from other plants such as corn，but there are a few reasons why cactus is a better choice.First，prickly pears need very little water verylittle care，and grow well in hot temperatures.Today，these characteristic（特點(diǎn)）are key.Also，unlike corn，prickly pears don't need space that could be used for other food plants.They can grow in areas where many food plants can't grow.Last，after making gas from prickly pears ans manure，their byproducts （副產(chǎn)品） can be used to help grow food.
Scientists still need to do more research on making prickly pear gjye.ai.As projects like Nopalimex show，we have the possibility to produce more sustainable fuel to power our lives.
