I have thought, for a few years now, that we should take the exhaust the comes out of the smoke stacks and pump that exhaust through water, that has algae in it. I think that the algae would use the CO2 to make O2. Seems like a good idea to me. I have to agree with you about the sequestration. One example that comes to mind in the Yucca mountains. Some people want to bury nuclear waste there. They try to say it is safe while other scientist have concerns about earthquakes and things like that. I think that the algae could be harvested and use to make such things, such as biodiesel.
