What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Using Sewage To Grow Algae To Produce Biofuel

What's the Latest Development?

The Spanish resort town of Chiclana de la Frontera can now lay claim to the world's first municipal sewage plant that purposely uses wastewater to grow algae that is then converted into clean biofuel. Carbon dioxide from sewage produces the algae, the first crop of which was harvested last month. The resulting biomass will be made into vehicle fuel, which should be ready for use by December. Right now the plant is still in a pilot stage and fairly small, but plans are to have it fully operational by 2015, growing enough algae and producing enough fuel to run about 200 cars a year.

What's the Big Idea?

Plants in other industries have generated biogas from wastewater for internal use, but All-gas is the first to systematically cultivate algae from sewage to create a fuel for outside use. The plant is reported to be much cheaper to build and run than a conventional sewage plant, which is good news in a country that's been hard hit by the European financial crisis. It remains to be seen whether All-gas will be able to provide fuel on a large scale, but other small towns in Spain have expressed interest in building similar plants.
