The Vriliac Pedal Power Generator is an exercise machine that produces 40 watts of 12 Volt power.
It is both an exercise bike and table top generator and provides light as well as power.You can easily build one from scratch in a couple of days and it fits inside a neat go bag for portability.
The plans are free and all of the parts are available at Lowes and on Amazon. The Vriliac can power a laptop and two cell phones at the same time and is engineered to be trouble free and reliable. It would be an awesome product for the Ben Heck Show.
