I'm not trying to say this isn't a good idea (maybe they should think of the quantum nature of sunlight capture), but...
aren't they kinda trying to improve on nature's already pretty efficient photosynthesis.
Pretty efficient photosynthesis? Is every square meter of Earth's surface covered by a photosynthesizing leaf? And what if you want CO as a product? I think figuring out how to use sunlight to convert light into chemical energy is an important area of study.
and by the way,
...wouldn't increasing the productivity of the earth soak up a lot of CO2. Y'know, like the oceans -phytoplankton, etc., up the food chain. Is it really true that 90% of the large fish are gone from the oceans? Maybe fertilizing the oceans isn't such a crazy idea after all (done very carefully)?
How do you propose increasing the productivity of the earth? Do you really feel that what the oceans need is a good shot of fertilizer? Do you think we're NOT loading the oceans with nutrients, as we speak? Assuming that you agree we ARE loading the oceans with nutrients at this very moment, how come we have a problem with the availability of large fish?
