Scientists and engineers are always refining the technologies we use to accumulate energy, and even creating completely new ones. Toll Free Forwarding (via Inhabitat) collected some of the most interesting trends into this infographic.
Continuously-decreasing cell prices are making solar power more viable in more applications, and that trend is expected to continue. Apple is developing a “sapphire glass” solar-charging screen, while Ford is demonstrating a C-Max Energi plug-in hybrid with a solar roof.
If that’s not good enough, how about spray-on solar cells? England’s University of Sheffield is experimenting with a paint-like medium for applying a photovoltaic active layer onto different surfaces.
If that’s not sci-fi enough, scientists are also experimenting with sugar batteries, and ways to harvest energy from human heartbeats and steps. It’s the making of a bright future, or a Matrix-like dystopia, depending on your point of view.
