An electro-hydrodynamic system including an energy harvester and an adjustable member, wherein the energy harvester includes a charge source including: an injector configured to emit particles into a wind stream and an electrode configured to charge the particles to a first polarity and to generate a first electric field. The adjustable member supports the energy harvester, and is configured to control a distance between electrical ground and at least one component of the energy harvester. A method for controlling the electric field magnitude of an electro-hydrodynamic system including placing an energy harvester comprising a charge source at a distance away from electrical ground, the distance being an equilibrium distance; receiving a first measurement of a parameter indicative of electric field magnitude near the charge source; and in response to the first measurement surpassing a threshold, increasing the distance between the energy harvester and electrical ground. |
