A Professor of chemistry at the University of Texas at Dallas, Ray H. Baughman has developed fuel storing, self powered "muscles" that are 100 times for powerful than our own. Evidently there are two kinds of designs for this muscle. One involves two types of metal and fuel like methanol. Chemical reactions cause expansion and contraction (like muscles). The other type is composed of tiny carbon tubes and a reaction between a fuel and oxigen. The resulting electrical charge causes expansion and contraction of the material. The application is reportedly intended for robots, but I am wondering if there is some possibility for cybernetic application? Imagine what it would be like to someday be able to replace our own tissue with devices that out perform the original? The Dr. Baughman suggests that the new technology is simple enough that commercial uses could be only three years away.
