With "smart" cell phones, Wi-Fi, RFID tag systems, and so many other new applications for radio waves these days, it is obvious that we are immersed in an electromagnetic field ("EMF") just about everywhere we go. Here's a circuit to experiment with collecting and measuring the energy present in our environment.
This alternative energy project is two-fold. First, convert a two-cycle engine to run on pressure (air/steam). Then, create a control system to optimize engine performance. This project is very easily reproduced by any experimenter with average mechanical skills; the controller is an easy breadboard; and — best of all — it’s cheap and green!
