Abstract: A magnetic air car uses a magnetic motor to compress input air and save moderately compressed high-pressure air in storage tanks. The compressor and storage tanks deliver the high-pressure working air and operational flows to several stages of compressors that boost the pressures during driving to very high-pressure, then ultra high-pressure, then super high-pressure, and finally to extremely high-pressure.

The balance of forces between the two ends of a coupled turbo pair allow a simple air bearing design to operate safely and reliably at high rotational speeds.
