Is Earth's infrared radiation a potential energy source?

At any given moment, our planet bleeds 100 million gigawatts of infrared radiation back into space. Needless to say, converting this wasted heat to a renewable energy source would be a sure-fire game changer. Physicists from Harvard University may have just figured out how to do it. » 3/04/14 12:20pm 3/04/14 12:20pm

This gorgeous skyscraper is also a wind power plant

Behold the Pertamina Energy Tower, a U.S.-designed building that's slated for construction in Jakarta, Indonesia. Reaching a height of a half-kilometer, the tower will harvest its own wind energy through an opening at its peak. » 12/11/13 8:45am 12/11/13 8:45am

No, Extreme Human Longevity Won’t Destroy the Planet

It’s only a matter of time before humanity solves the aging problem. And resistance to radical life extension has already begun, driven by fears of overpopulation and the exhaustion of our planet's resources. Here’s why the critics are wrong. » 10/02/13 11:52am 10/02/13 11:52am

Could stunt kites be the future of wind energy?

The idea of harnessing the energy from wind by using ground-based stations linked up to atmospheric turbines is gaining traction. Trouble is, they're expensive, unwieldy, and prey to low winds. Moreover, why go to all the trouble of building massive wind turbines when something much simpler exists? Such is the… » 11/06/12 2:40pm 11/06/12 2:40pm
