Water without water

Inspiration: I got inspired from learning about the ability of plants to feed itself ( autotrophic) so why can't it water itself by some help??

Mechanism: When we plant in the desert, we take water from nearby wells, that

only transports water from a place to another, bringing drought to some places to water others.So what if I told you that you can water plants by plants. During respiration, plants like any other living organism, takes in oxygen and let out carbon dioxide, and vise versa in photosynthesis process. That means oxygen is available here. So if we plant in special green houses to make oxygen trapped in , and then we use tubes filled with liquefied hydrogen in it, the tubes should be insulated to keep a certain temperature to keep the hydrogen liquid , We put argon in these tubes with a ratio 1 ml. of hydrogen:2 ml. of Argon, to decrease the amount of produced energy to 73% and increasing amount of water molecules to 27%. Reaction of hydrogen and water produces water molecules with a big bomb of energy, so we will need holes 1 cm. in diameter ever 5 cm. to allow energy produced to be collected in tanks above the tubes, to be used in electricity production or any other application.
