A casing brush tool for cleaning interior walls of a well bore casing. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. The displacement of the dynamic assembly causes a plurality of the electromechanical coupled elements to simultaneously flex, generating an electrical charge which may be either stored in the charge storage device or which may directly power the power consumption device. Each of the one or more resource proxies can use the application tenancy context of a thread to communicate with a tenant specific resource.
