Computers
That's right. The future of computers is water and graphene. They would be combined to make a new type of transistor. Transistors are the on and off switch in a computer. They stop or start the flow of electricity.
Water and Graphene are both good conductors of electricity. So how will they make a transistor? Graphene does not have an 'off' switch when electricity is running through it, due to its symmetry. However, when water is added, water is attracted to the graphene, glomms to it, breaking its symmetry. Without the symmetry, graphene is now a poor conductor of electricity, or turned 'off'.
This is technique is not new, but using water is a breakthrough. Water is not dangerous, explosive or expensive.
