One Variety of Sea Slugs Cuts Out the Energy Middleman
dragonturtle69 writes with this story, short on details but interesting: "These sea slugs, Elysia chlorotica, have evolved the ability to gain energy via photosynthesis. Forget about genetic modifications for sports enhancements. I want to be able to never need to eat again — or do I?"
I want to be able to consume as many extra calories as I like, and then radiate the excess as visible light, with radiant area, spectrum and direction under my conscious control.
Or, at least, I'd like to be able to metabolize my food and store excess energy as electric charge, easily transferred to whatever devices are handy.
