Weaving muscles from spider silk

Using only water and pressure, it is possible to develop a stretchable, flexible wire made of spider's silk that will be able to conduct electricity as well as copper - opening the door to new forms of artificial muscle.
The conductive threads will be made from the dragline silk from the webs of common orb weaver spiders, which are chosen because they construct very large webs. The thread will be mixed with dry nanotubes, dampened to encourage adhesion, and then pressed between a pair of Teflon sheets.
