Graphic Series: Earthly Ideas, Week 8

Editor's note: This post is part of a series. We'll be releasing one of Worldchanging ally Andy Lubershane's original comics each week until the end of the year. While many of the issues covered in the comics have been discussed on Worldchanging in the past, we hope that you'll be able to use this new medium in a different way … whether it's in your classroom, on your office wall, or to help explain ideas to friends and family.

This week's cartoon describes Enhanced Geothermal Systems. We’ve written several times about these innovative, energy-efficient systems for heating and cooling and generating power, which take advantage of the naturally existing heat below the Earth's surface. Jamais Cascio posted on Geothermal Heat Pumps back in 2005. And in 2007, writer Karl Schroeder reported that geothermal power options were growing so quickly in Canada that geothermal might one day replace coal as the nation's main source of electricity.

Andy,

I wanted to correct your comic on how a residential system works. I recieve alot of questions on how the system works and it is largely due to the consumer reasearching online how a residental geothermal system works and finding incorrect information. Please review my site to learn the proper way a geothermal system works if you dont already know. I understand it is only a comic but the public sometimes really believes the geo system takes cool air from the ground and puts it in the home.

Thanks
