If you read the application you will notice that this one is more special than yours
It has an efficiency of at least 100% if you read the application

Brief Summary of the Invention 
 I claim you can create more electricity than what it takes to run the air-compressor. 
The device creates more power than what it takes to power the device. 

I am always amazed by people claiming perpetual machines.
