Collecting Charge Current

All three types of basic particles are ejected, for the collection of electric charges,

where a small positive potential prompts the negative charges to flow in shown direction.  The suspension of $TiO_2$ is as designed in the last post "Sun Capture" dated 20 Dec 2017.  This is a high current device that produces a high current with a low applied potential.

What about gravity and temperature particles?

Good night.
