Underwater cropping of terrestrial plants

Not stupid, underwater biospheres:

Stable humidity, temperatures ranging from little amplitude, excess of CO2 at will, all this looks interesting ...
... except access.

A future ?

No...

Already the construction. Already it seems that we will not have enough resources for everyone to drive in electric cars, a practical excuse to continue with fossil fuels, so go build underwater bubbles to feed humanity! lol
Then photosynthesis, a few centimeters of water is already enough to absorb a good part of solar spectrum, so several meters of water + a glass bubble of a significant thickness (because of the pressure) it is not worth it to count on a very fast growth of the plants ... that's the crazy output that we can expect : Mrgreen:
You have to see the "biosphere II" adventure and the reasons for its failure.

The argument of loss of solar spectrum is admissible, but valid only if it is shown that the excess of CO2 that can easily be obtained underwater, as well as the better conditions of humidity or temperature, do not occur. do not offer superior benefits to this disadvantage.

As for "Biosphere II", the ambitions were not at all the same, it is not comparable.

To assimilate the CO2 from the air the plants need energy.

The ambitions of Biosphere II were not the same, but its failure for the same cause as the future failure of this "innovation".

It is above ground culture :P

For the light it's simple, yaka put a raft with pv panels on top and leds in the bubble ...

But I do not understand how moisture could condense if the temperature is stable?

A peremptory prediction Nostradamus associated with an empty folder, comparison is not right, it leaves stunned.

Putting complicated words to deny evidence does not change reality.
