Patent number: 10012113Abstract: A combined cycle power plant for frequent stops and startups comprises at least one gas turbine, a heat recovery steam generator, at least one steam turbine and a thermal energy storage and retrieval system utilizing latent heat of fusion. Phase change materials receive thermal charge from two sources: (a) renewable energy generation plants, when their production exceeds demand and (b) gas turbine exhaust heat. The thermal energy storage and retrieval system, discharges efficiently thermal energy for steam production, which keeps the at least one steam turbine preheated and ready for fast startups, thus increasing the plant's flexibility and efficiency. A novel two stage latent thermal energy storage system provides at least supercritical steam.Type: GrantFiled: March 16, 2015Date of Patent: July 3, 2018Inventor: Vassilios Vamvas

Patent number: 8841822Abstract: An efficient electrical power generator employs a plurality of piezoelectric devices in a rigid container. The top cover of the rigid container is capable of moving and in direct contact with a large hydraulic cylinder. A small cylinder, hydraulically coupled with the large one, through tubing is capable to displace a liquid contained in the tubing. An input force applied on the small cylinder, is multiplied by the large cylinder, which compresses the piezoelectric devices causing them to produce an electrical output.Type: GrantFiled: November 15, 2011Date of Patent: September 23, 2014Inventor: Vassilios Vamvas

Patent number: 8723350Abstract: A device comprising a float (5) and a pivoting assembly of a rigid beam (10) and an elastic beam (30), firmly connected to each other, pivoting about a stationary point (15). The device transforms the rise and falls of the ocean waves into usable mechanical energy. In one embodiment, the elastic beam is latched into a latch mechanism (150). The latch mechanism obstructs the elastic beam to continue moving. The elastic beam deflects and accumulates potential power. When the elastic beam is released, it moves with a high speed and momentum. In another embodiment this momentum is utilized to counter-rotate an electric generator's two rotors (251, 252). A method of transforming the energy of a mass in reciprocating motion to electrical power.Type: GrantFiled: October 28, 2011Date of Patent: May 13, 2014Assignee: Vassilios VamvasInventor: Vassilios Vamvas
