Researchers in Sweden have developed an affordable and effective way of gathering, storing, and releasing energy from the Sun, through a new process that could conceivably store the trapped solar energy in chemical form for decades, which can later be released on demand when needed.

Researchers at RMIT University in Melbourne, Australia has developed a new method that can allow liquid metal to self-arrange its own shape, using external chemical inputs. The substance is made up of a highly-conductive liquid-metal core, surrounded by a film of semiconducting oxide skin, allowing the arrangement to be completely malleable, resembling the mimetic polyalloy used by the T-1000 from the Terminator movies.

The technique used to cause the metal to rearrange its shape involves changing the chemical makeup of the water that the metal is kept in, altering the pH levels and salt content of the solution. This prompts the skin surrounding the metal to change its shape, to the point where this change can cause the metal blob can propel itself.
