Development of innovative technologies for hydraulic concretes of new generation, with modified structure, high strength of low anisotropy, mudflow and earthquake resistant, on the basis of resources of   Southern Caucasus. Like everywhere in the world, hydraulic structures in Georgia are built using concretes which are not stable against mudflows and seismic tremors. This instability results in the wear of the surface of hydro-engineering structures, their destruction by mudflows and crushing by seismic tremors. Hence the prevention of hydraulic concrete instability by the innovative combined micro- and self(nano)-reinforcement of the concrete structure is a topical goal. 







WAVE ENERGY CONVERTER (WEC) M-2

A main element of wave energy converter is an axle, consisted of several solid cylindersconnected one to another by an elastic pipe or by hinged sections, with a wave receivers moving along the cylinders.Converter can be placed on the water surface, or submerged into the depth, where wave parameters are enough for the converter effectiveoperation. For this goal the device has to be anchoredto the sea/ocean bed by two or more ropes that help to place it horizontally at the desired depth. The appliance is placed in the direction of the wave propagation.

The axle is made of nonflexible and antimagnetic material, with the inductors fixed immovably in it.

BREAKWATER

The breakwater representsat least one hollow parallelepiped or cylindrical shape object and submerged in water fixed to the bottom in the direction of wave propagation, because of hollowness the wave flow hasforward and back motions
