The device of claim 1, wherein said source comprises a radioisotope emission high voltage source. 3. The device of claim 2, wherein said source comprises S35. 4. The device of claim 2, wherein said source comprises P32. 5. The device of claim 2, wherein said source comprises P33. 6. The device of claim 2, wherein said source comprises Ca45. 7. The device of claim 2, wherein said source comprises Sn123. 8. The device of claim 1, wherein said source comprises at least one of piezoelectric crystals and Van de Graff generator. 9. The device of claim 1, wherein said actuator is a disk rotor. 10. The device of claim 1, wherein said actuator is a vertical wall rotor. 11. The device of claim 1, wherein said actuator is a stacked rotor. 12. The device of claim 1, wherein said source comprises a replaceable source. 13. An electrostatic rotary actuator method comprising:providing emission from a source;capturing said emission by a target material;generating rotation from electrostatic force; anddischarging developed potential;wherein said actuator implements partial discharge; andwherein said partial discharge comprises a storage capacitor re-charging said target. 14. The method of claim 13, wherein said source is a radioisotope providing said emission. 15. The method of claim 14, wherein said source is a low atomic number, below about 17, beta emitter source. 16. The method of claim 14, wherein said radioisotope source further provides electrical power. 17. The method of claim 13, wherein said step of discharging comprises partial discharge. 18. A radioisotope fueled electrostatic disk rotary actuator nano air vehicle apparatus comprising:two pairs of chutes comprised of metal, wherein said two pairs of chutes comprise a surface film of a light metallic element;a rotating vane disk, between said two pairs of chutes and coaxial with said two pairs of chutes, said rotating vane disk comprising twenty four source vanes comprising beta-emitting radioisotope comprising at least one of S35 and Ca45, wherein said radioisotope comprises a source film with a thickness of about approximately one half penetration depth, whereby current is a maximum;a housing comprising a lead-plated vacuum envelope, enclosing said two pairs of chutes and said rotating vane disk, whereby emission products of said radioisotope are contained, said vacuum envelope is sputtered deposition plated with a lead layer of about approximately one micron, whereby surrounding area is protected from soft X-rays, and beta upset of localized electronics is prevented; andwherein rotation of said rotary actuator is magnetically coupled directly to a propeller component, thereby eliminating losses due to a mechanical gear box, whereby propulsion is provided to said nano air vehicle.
