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.

Plenty Of Wind Power Available; We Just Need To Get It

What's the Latest Development?

Right now, wind power could easily provide all of Earth's energy needs with plenty to spare, according to a new study published this week. The authors have estimated "a potential of [400 trillion watts] of wind power at the Earth's surface and [1.8 quadrillion watts] of power from the upper atmosphere" -- dwarfing our puny 18-trillion-watt usage. Some of that higher-altitude energy could be tapped by turbines that would float kilometers above the planet.

What's the Big Idea?

Realistically speaking, other energy sources will always be needed, says Ken Caldeira, co-author of the study. However, if all this wind energy is available, there must be a way to get more of it, considering that currently it only supplies about 1 percent of the Earth's needs. Unfortunately there are a number of significant hurdles to overcome, including finding the money to construct more turbines and finding the landowners, both public and private, who are willing to host them. The wind is there...but Caldeira says, "[E]conomic, technological or political factors will determine the growth of wind power around the world."
