Zired mobility
Zired engine:
If air is the best resource for mobility, then the zired engine is the ideal device to make the most out of the excellent properties of air. As a compressor, it can convert air through rotary motion into compressed air. This qualifies the Zired engine to generate potential energy. Later the same device, this time as an engine, can simply convert the compressed air back into rotary motion. This means the Zired device can be used in two ways for mobility, and with far more efficiency than any other device out there today.
