HYDRO-WAVE POWER.

NOVEL PROPULSION.

Wave transmission, a new metr of transmitting and applying pow is at present attracting attention Britain. It was discovered by 1 George Constantanesco, and is n protected by patents in the ch countries of the world. It is claim by the patentees that wave transm sion is applicable to most industr purposes, as it combines many pr tical advantages with high efncier and great economy in the distributi and application of power. ' In n< technical language wave transmissi is the name chosen to distinguish sixth method for the transmission the five at present in co merciaT use being steam, direct m» anical, electrical, compressed air, a hydraulic. In its development wi motions or pulsation set up in an \ closed column of liquid are employ The liquid (usually water) is c< tained in a system of piping conne ing thfti- 4:pajains generating 1 wave motions to tbe machinery whj applies them in useful work, differs from hydraulic tranmsissi in which a continuous flow of liqi is utilised, whereas in wave, tra: mission there is no direct flow. 1

liquid itself merely pulsates ba wards and forwards about a m< position, not as a flexible "connect] rod," but as the result of sections waves of compressed fluid travel! along one after another at the n ural speed of sound. Water is o: lelatively incompressible, and it its elasticity* which'is taken adv; tage of in the wave transmission s tern. An analogy from elasticity drawn between ordinary hydraulics represented by the continuous c rent and wave transmission by i alternating.current system. The si plest form of wave transmission illustrated by two cylinders fitl with plungers, the cylinders on 1 under-side of the plungers being o nected together by a long pipe fill with water. If one of the plungi is moved rapidly up and down it v set up at each downward stn tyives of compressed water, whi travelling along the pipe at the sp< of, sound (about 4800 ft per seconj will exert their energy on the pk ger at the far end, and if this leaded, a simple reciprocating moti will be produced in exact synchn ism with the reciprocations- of 1 first plunger. The equipment necj sary is claimed to be simple a cheap; and the claims put forwi on behalf of the new power are o tainly arresting., The development I this power is worthy of close atti tion by those who are interested, s if it.succeeds as expected, the wo will be,enormously enriched wHi e sequence;/; %L
