Do you think this is possible and what age your thoughts? Following many decades of research, a number of human-plant chimeras are moving from the laboratory into clinical and commercial use. Among the treatments now available is a method for combining the photosynthetic capabilities of chloroplasts with human skin. This enables a person to gain energy from being exposed to sunlight.

In 1990, scientists first coined the term "kleptoplasty" to describe a symbiotic phenomenon whereby plastids, notably chloroplasts from algae, are sequestered by host organisms. This had been observed in Elysia chlorotica, a species of green sea slug that absorbed chloroplasts from the algae it ate, making it effectively a solar-powered animal.
