Abstract: A modular wave energy converter includes: a forward attachment frame; forward guide rails coupled to the forward attachment frame; a forward paddle coupled to the forward guide rails; and one or more forward tethers coupled to the forward paddle and the shaft. A combination of heave and surge forces from waves of water causes the forward paddle moves up and down the forward guide rails.

Abstract: Thermoelastic constants of cellular and lattice materials are tailored with pre-stress using four configurations. First, a tube-core composite uses lightweight materials as a core. A screw cap is used to adjust the pressure on the lightweight material core, tailoring the thermoelastic constants of the overall composite. Second, pre-tensioned fibers or metal wires are embedded in the lightweight material during the fabrication and curing process to form a composite. After the lightweight material is solidified, the pre-tension is released from the frame and transferred to the composite. Third, the lightweight material is fabricated in a mold with fiber or wire reinforcements, where the ends extend beyond the lightweight material and are coupled to bolts. Post-tension is applied by adjusting the bolts. Fourth, the ends of the fiber are coupled to a spool. Post-tension is applied to the fibers or wires by turning the spool using a single screw bolt.
