Self-contained ecosystems on your desk. Eco-spheres strike a perfect balance between members in an environment. Based on NASA studies, they can last past 10 years. Is it feasible to have more complex self-contained systems in the near future? Imagine, a sealed tank with a 'pet' you never have to worry about feeding, watering, or cleaning. That doesn't use batteries. Plus, they look pretty cool.
