- inactive, on 08/27/2008, -1/+15The idea of using caves/tunnels to store wind then release it...is just beyond cool...and quite science fiction. I really hope that this catches on/is feasible.
- kellfinder, on 08/27/2008, -1/+13Huge step in the right direction towards a goal of making alternative energy more mainstream.
- inactive, on 08/27/2008, -1/+10nice energy breakthrough. Great article.
- paiute8, on 08/27/2008, -0/+8You know there is a company that wants to build Automobiles with this concept using compressed air and electricity and fuel
- WordsnCollision, on 08/27/2008, -1/+9Alternative energy meets alternative wind - very cool!
- JerichoSam, on 08/27/2008, -0/+7Very cool. I'd never heard of this.
- inactive, on 08/28/2008, -0/+6This is an absurdly inefficient idea! It could take forever to compress a cave system to usable pressure, nevermind the extremely high chance of natural cracks, fissures and other leaks in the plan.
A better idea would be pumping WATER into a holding area (dam, valley, tanks, swimming pool) and running that through turbines when the wind drops off. It's controllable, sustainable and craptonnes more logical than pumping air (and money) into a hole in the ground - ancientdinko, on 08/28/2008, -1/+6hmmm... I once watched how a coastal cave pumped out huge blasts of air as that air was getting displaced by rising tide/waves. I figure not only could 'trapped' compressed air drive turbines, the water that fills the cave chamber could drive turbines as well. I began working on a model which is here:

- Mizzy, on 08/28/2008, -0/+4I'm glad to see that more and more Wind turbine systems are being experimented with and used. Green Power!
- lewikee, on 08/28/2008, -1/+5The first 7 people commenting are obviously stooges. For example: "louiebaur Its a wonderful content you have got there!!!" "Very cool!" "Great article!"
Yah, ok. Make it less obvious. - fish42, on 08/28/2008, -0/+4The whole idea sounds like some massive tax dodge by the investors, as i find that hard to believe it would ever produce usable amounts of electricity compared to the amounts put in.
cool idea tho, what anout using the old gas expansion tanks about cities to do that. a lot easier than trying to seal an entire cave system. - Diggopolis, on 08/28/2008, -0/+4The concept behind this sounds feasible, however I recall that some of the previous attempts at this were not as successful as they would have liked to have seen. That's ok, not every great invention works perfectly the first time tried. Good Article. :)
- AmyVernon, on 08/28/2008, -0/+3If this works, that'd be really wild. "Hi, would you like to buy some air from my cave?"
- trolleyfan, on 08/28/2008, -0/+3Well basically because you need a lot of water. And water storage systems (that are big enough to make this worthwhile) are expensive.
This would be good for intermittent power supplies like wind and solar. Yes, it's inefficient - but as it's essentially storing power that would just be "thrown away" without it, even "inefficient" is better than what we've got. - Lucas123, on 08/28/2008, -0/+2I'm a little confused. You're using power to create compressed air in a cave and then generating power by releasing it. What's the ratio of pressure creation to energy production? And, I would think that a cave system would be almost impossible to make air tight and that, when pressurized, air would seep into porous rock. I've got to admit, I would have never thought of this one, but perhaps my knowledge of the subject is what's lacking.
