Abstract
Abstract A system for producing nitrogen fertilizer using an electric arc process is described in which the electric arc necessary for the process is generated by piezoelectric elements actuated by a hammer mechanism powered by water pressure such as from a garden hose. The nitrogen oxides produced by the arc discharge are drawn into the water to serve as a source of nitrogen fertilizer. The net result of the invention is that the operator can provide nitrogen fertilizer as he supplies water to the same area. The only inputs to this system are air and a source of water under pressure.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
93 words
A water-powered piezoelectric unit for producing a nitrogen fertilizer solution from air and water: said unit comprising an electric arc generating means constituted by piezoelectric crystals (8) which are actuated by hammer element (6) driven by spring element (5) powered by turbine blade (3) located in conduit (21); wherein in operation water flowing through said conduit turns said turbine blade, actuating said spring mechanism which causes said hammer element to strike said piezoelectric crystals causing an electric arc spark discharge which causes nitrogen and oxygen to combine to form said nitrogen fertilizer solution.
