Changes in the company leadership, board etc make the assumption that the device(s) work and just need a bit of a sell. This is just not true. The devices are part and parcel of the scam. If they worked they would have sold. Lets face it folks, electrocuting or putting a magnet on your oil doesn't generate any cost savings at the pump whatever else it might do in a lab under the right conditions.
The "right changes" for the current and past management of this company is arrest, trial, court orders, and bailiffs.
