"room temperature circuits spend heat energy stored in kinetic traps, like molecular springs, recharged with heat pulse... reusability through kinetic traps isn't limited to heat, but for any energy source where can break weak bonds between molecules letting them fall back into their traps, such as light, salt, acid gradients... long term neural network and logic circuit tasks like those of living systems... smart medicines, cargo sorting, self-hydrating contact lenses, self-repairing strain cracks, molecular computers"
