Interesting idea. I think if there is a hill that pumping water to the top will probably have less losses. One issue with compressed gas is the act of compressing it makes it hot, and for long term storage that heat will be lost. The greater the pressure, the greater the heat and the greater the loss. If they have figured out a way to effectively use low-pressure air to generate electricity, it might work out really good. But if it's just a turbine, high pressure makes the turbine more effective, so there will be a compromise either way. Short term storage - as in day vs night - the heat could be retained and then the system looks pretty good. Except for the explosion dangers. -- Philip, speaking before reading up on the details _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
