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.

Getting Energy From The Ocean Floor

What's the Latest Development?

A consortium of companies, including Eaton Corporation, Triton, and others, are in the process of building the first-ever collection system designed to harvest energy from the currents found in the depths of Earth's oceans. Triton will build the 1-megawatt turbine that will sit on the seafloor, and Eaton will design the software and connections that will bring the energy to the grid. It's the latest in a series of recent ocean energy initiatives which include September's launch of the first tidal power station for Maine.

What's the Big Idea?

Eaton executive Jim Spaulding explains the importance of viewing ocean currents as a possible source of renewable power: "[They] are generated by differences in the ocean's salinity and temperature around the continents [and] run at a constant speed of about 3 to 5 knots. That's the appeal: [they're] very, very consistent." One possible spot for the first demonstration of the system is somewhere off the coast of Florida, where strong currents are available at easily-accessible depths. According to Eaton representatives, "the 1-MW demonstration project could easily be built up to a utility-scale current farm by adding more turbines."
