<The idea of compressing CO2 and then storing it '20,000 Leagues Under The Sea' is just crackpot. It's a lot cheaper to plant a tree plantation> Ray, I did an extensive scientific investigation of the 20,000 leagues in 1987, but my memory is as good as Google, so I can tell you that the energy cost of the process is only 20%. The depth required is only 400 metres to retain liquid phase. Little turbines in the pipe would also be good generators. With a specific gravity of 1.2, liquid CO2 falling 400 metres would generate a decent amount of electricity. It might even be worth taking it a lot further to get even more generation if the cost of pipework and water depth allows. It was sufficiently uncrackpot for Mitsubishi to patent the idea, so there was more than me thinking it possibly worthwhile. That patent would be expiring soon. Of course, what's really crackpot is the idea that plant food in the atmosphere is a bad thing. If plants could have a vote, they'd vote for CO2 into the atmosphere and lots of it. I also like the idea of planting Australia in pine trees, and photovoltaic panels, and have advocated that idea for many years too. Mqurice
