    Forget the course on learning about solar power, I'm going to eat green algae. My reasoning is that if I eat enough of it, I can become photosynthesis. Perhaps even regrow my body if I ever lose my head.

      Many times it has been suggested that perhaps one day we can incorporate photosynthesis into our tissues and so not need to eat anymore. Allow me to clarify that iirc it's been calculated that we'd need a photosynthetic surface area about as large as a football field just to power our resting energy use, let alone any actual activity. You wouldn't be able to skip even a single daily meal by relying on solar power. So while fun to contemplate, it's not really all that practical. So how do plants, and these slugs, do it? Simple - they use barely any energy to begin with. Even these literal snails can't survive indefinitely on just photosynthetic energy, and we use way more power than snails do. And plants ofc use even less power.

      I don’t think it would work with humans, but there is one species of vertebrate that is known to use photosynthesis: the larvae of the spotted salamander. Their nursery pools don’t have predators but as a trade-off are really nutrient poor. So, the developing salamanders incorporate green algae into their tissues and the algae provide them with oxygen and carbs as they photosynthesize!
