Cars to Run on Cactus
“In Mexico, cars will soon run on cactus. A company has built the world’s first digester to make biogas from the desert plant’s fruit, according to media reports.
The fruit or prickly pears are pureed, mixed with manure, then left to decompose, producing methane. That gas is used for fuel and burned to generate enough electricity for 300 homes at 50% cheaper than grid prices.”
