Re: Should be able to watch photosynthesis, too ...
Does any of all this have an application that could be put towards terra-forming? i.e. such as gas converters to clean up the air balance a bit (co2-> o2 for example, extracting the carbon in solid form).
Having said that, The Earth is a pretty big engine, so doing something on a scale that is relevant is most likely out of our reach until the human race faces extinction unless it does something.
