Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
110 words
A MAGNETOHYDROHYNAMIC GENERATOR COMPRISING A FIRST INNER ELECTRICALLY CONDUCTIVE MATERIAL, A SECOND OUTER ELECTRICALLY CONDUCTIVE MATERIAL COAXIALLY ALIGNED WITH SAID FIRST MATERIAL AND DEFINING AN ANNULAR SPACE THEREBETWEEN, A SOURCE OF ELECTRICAL ENERGY CONNECTED TO SAID FIRST AND SECOND MATERIALS FOR GENERATING A MAGNETIC FIELD IN SAID SPACE, CONDUCTIVE MEANS INTERCONNECTING SAID MATERIALS AT ONE OF THEIR ENDS, AN EXPLOSIVE CHARGE SURROUNDING SAID SECOND MATERIAL AND HAVING DETONATING MEANS ADJACENT THE OTHER ENDS OF SAID MATERIALS FOR INITIATING AN AXIALLY PROGRESSING WAVE IN SAID CHARGE TO PROGRESSIVELY COLLAPSE SAID SECOND MATERIAL TOWARD SAID CONDUCTIVE MEANS, AND MEANS FOR EXTRACTING THE GENERATED ELECTRICAL ENERGY FROM THE COMPRESSION OF SAID MAGNETIC FIELD.
