Panacea University

There are some fantastic courses on electricity and other technologies found here:
http://www.panaceauniversity.org/

If you have interest in electrical devices, I recommend checking out the John Bedini course and Imhotep Radiant Oscillator course.  The most incredible course includes information on how to build an electric heater that puts out 17x more heat than a traditional resistive heater while still using the same quantity of electricity.

I have invested thousands of hours of research into these particular devices as well as many others from all kinds of sources.  I am thoroughly convinced that the courses from inventors on Panacea University describe working inventions if you follow the build instructions correctly.

For some clarification, you will note that the "Courses" and "Research" are on the same webpage with Research listings being toward the bottom of the page.  The Research listings are for devices that people are still trying to figure out -- they do not include working devices.  The Courses listing is dedicated to known working devices with instructions on how you can replicate them.
