This disclosure is directed to hydrodynamic electric generators, including their structural design, methods of deployment, anchoring systems, drive systems and control systems. The system can be scaled from ones that can be hand carried to large, stationary devices that can generate up to and greater than 20 kw in a current of 3 knots. In a stationary system, the device can be anchored to an underwater floor by an anchoring device supported by four adjustable legs. These legs can eliminate the need for extensive mooring lines, providing the device with a small footprint that is non-hazardous to marine animals or vegetation. Individual components, such as rotors, generators and other mechanical components can be modularly installed for easy removal and servicing without having to disturb the entire system.

A composite for energy absorbing, non-slip surfaces is disclosed. The composite may be an elastomeric layer deposited and adhered to the surface of a substrate. The substrate may be a polymeric foam, a polyurethane, a closed-cell polyurethane foam or a metal. The elastomeric layer may include a plurality of elastomeric granules, made of a granulated synthetic rubber or more particularly a granulated Ethylene-Propylene-Diene-Monomer. The adhesive used to adhere the elastomeric layer to the substrate may be the same adhesive used to bind the elastomeric granules to one another. In some instances, the composite may include embedded devices or indicia. Composites in accordance with the present disclosure create a safer and more durable surface for marine and construction industries.
