It was the last stop before the x86 processor. It was used in the MITS Altair 8800. The first programming language written for it was Microsoft's first product, ALTAIR Basic.

Researchers at Georgia Institute of Technology have created a working prototype nanogenerator capable of generating as much as 4 watts per cubic centimeter of continuous direct current. The generators are green (to use), drawing power from natural motion in the surrounding environment. They are based on non-toxic chemicals and should be safe for use in biomechanical implants, but that's not their only potential use. From the artic
