General
In Nanosystems the power densities that are to expect to be (at least) possible with
electrostatics based electromechanical conversion at the nanoscale are conservatively estimated.
The power densities predicted to be at least possible already are unbelievably high.
Porting macroscale electrostatic machines to the nanoscale
The scaling law for electrostatic performance is very favorable for such niniaturization.
- pelletron
- Wimshurst machine
- Lord Kelvin Replenisher [1]
Machines needing obvious modifications for the nanoscale:
- Kelvin water dropper
Could that be done in a nanoscale version with shooting solid-state charged pellets? - Van de Graaff generator:
Charge seperation would be done in rather different way.
Well, avoiding rubber (since not a gemstone-like compound), it would essentially become a similar to a pelletron. (replicate nanoscale charge separation mechanism)
Alternative contacting
To avoid the need for graphite tunneling contacts which need quite some surface and dissipate some power a reziprocating drive could be electrically connected with flexing nanotube connections. The flex must be low enough to not disturb the electric properties (conductivity) of the nabotube too much.
