Last month, President Obama touted fuels produced from immense swaths of algae as the future of energy, providing up to 17 percent of transportation fuel. But how do you get from pond scum to energy-rich fuels that can power our machines?
Reporters from ClimateDesk, a collaborative news service, put together this video explaining how scientists are studying the algae in the lab, why it is a potential fuel source, and how small companies are getting into the game.
But will algae be able to replace car fuels in the near future?
"It's not a panacea, I don't think it's ever going to be a panacea" for anthropogenic climate change and sustainable fuel, said Andrew Green, the president of Garden State bioEnterprises, a company developing algae production technologies.
But David Rejeski of the Woodrow Wilson International Center for Scholars is taking a long-view. "You start peeling back a lot of the rhetoric and the jargon, what's underneath this is essentially the scientific foundation for the next industrial revolution," he said.
