Well, first, you can't store energy without first gathering it somehow. Beyond that, it's not a hypothesis, it's purely a numbers problem - it's mathematically inescapable. The average amount of solar energy that hits the surface of the earth is 3000-4000 kcal/m²/day. Plants have a photosynthetic efficiency of 1-3% - that is, they are able to convert 1-3% of the solar energy they receive into useable chemical energy. So, for a 1 m² plant, it can produce, at best, 120 kcal per day (3% of 4000 kcal) of useable chemical energy. You, being a normal human, probably burn through 1500-2000 kcal per ordinary day, or if you're exceptional, potentially far more - Olympic athletes in training can easily burn through 10-12,000 kcal per day. Anyway, the long and the short of it is that photosynthesis just doesn't produce the juice you need.

You just put a theory is search of a conclusion, and waved some magic wand from under your selfhood vanity to say "This it it, baby! My way or the highway!"

And here is my pratical rebuke of your proof: Alchohol burning engines.

Note that "The Plant Kingdom" dos not need "The Animal Kingdom" to survive, but not vice versa.
