Abstract
Various embodiments are directed to a magnetic and osmotic inner tube for insertion in vehicle tires. The magnetic and osmotic inner tube may include a nonpermeable membrane ring coupled to a semipermeable membrane ring, an O-ring, and a group of polar magnets. The nonpermeable membrane ring may be coated with a sealant and store hypertonic fluid and plugging materials. The semipermeable membrane ring may store hypotonic fluid and plugging materials. When a vehicle tire is punctured by an object, the hypotonic fluid and the plugging materials are drawn by osmosis through the semipermeable membrane ring into the hypertonic fluid of the nonpermeable membrane ring to create an osmotic pressure on the nonpermeable membrane ring that causes the O-ring to seal the puncture. The polar magnets may be arranged, in parallel, to generate opposing magnetic forces that create a magnetic field that supports a vehicle weight.
