Many efforts to supplant traditional energy sources have amounted to a lot of talk and millions of dollars in research so far. But one idea is no bull.
A new processing plant in California captures natural gas (methane) from cow manure, Reuters reports.
Water is added to the manure to make a liquid put into a tank the size of five football fields and 33 feet deep. The gas is siphoned off and piped to a PG&E power plant to produce electricity.
Since the methane, which is considered a greenhouse gas, would have been released into the air, the setup is viewed as a double-bonus. But there are limits to the idea’s potential: Not all of the state’s 2 million dairy cows poop close enough to methane pipes for feasible collection, the story states. Could it not be stored and trucked?
