The six-legged RiSE was inspired by how geckos and cockroaches climb vertical surfaces. Full of sensors and funded by DARPA, the robot climbs walls, fences, and trees, changing its posture to conform to the changing curvature of each surface. Microclawed feet help it negotiate textured surfaces, and each of its six legs is powered by two electric motors. (Source: Boston Dynamics)
Good science fiction was never about the technology or the imagination of the author. It was about the effect that technology had on people. It was people stories in a scientifically extrapolated setting.
For example: Forbidden Planet was about our hidden emotions and what could happen if they were given the power to express themselves.
The Caves of Steel (Isaac Asimov) was about the consequences of automation on people. It was examined in the context of a mystery story.
Planet of the Apes examined our self destructiveness by looking at a potential aftermath (the human race cripples itself leaving room for Apes to advance).
The problem with science fiction today is that it has moved into the realm of fantasy. It is no longer about potential futures and how we fit into them, or the consequences of our choices. It is about adventure in an imaginary landscape.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
