a researcher who is retired lecturer of Electrical engineering. This is his invention. This machine has two power consuming parts, one is a blower and the other is called PEB (that's the trade secret and main part of the invention). The blower creates and blow and the PEB enhances the velocity of the flow at expense of internal enthalpy of the airflow created by the blower. This enhanced airflow is then used to rotate one or more windmill type turbine and electricity is generated. The latest experimental result is like this: Input voltage: 3.7 V and input current: 0.15 Amp; while output is 3.8 V and 0.15 Amp. All the experiments were done with small and inefficient machinery. Blower efficiency of blowers can be as high as around 60% and the turbines too can be built so that more power can be produced. At present, the output is just 2% more than the input. But with proper funding and better machinery, output can be doubled with this present machine.
As per the present "knowledge" of physics and engineering, the output can't be more than 36% of the input. First, the blower is not 100% efficient, it's maximum efficiency with market available systems can be 60% maximum. And, as per Betz law, the windmill type generator can convert only 59.3% of the kinetic energy contained by the airflow. While the output generated exceeds far more than this "theoretical limit". So, there is little chance of error.
This machine is now open to examination but at the cost of "skeptics". The inventor isn't a rich man that he can sponsor the visit of curious examiners. And I am requesting on his behalf suggestions from others here regarding how to go forward with and make it a successful technology to save the world.
