Motorized Electrostatic Generator with Carbon Fiber Brushes

This is a small Voss type electrostatic generator that uses carbon fiber brushes. The carbon fiber brushes have very little drag on the rotor. That low friction factor allows the generator to be powered…

Measuring ohmical resistance of different carbon fiber sheets

In this video I show the ohmical resistance of some different carbon fiber sheets in about 1 cm or 1 inch distance measured with a digital multimeter. http://www.overunity.com/13282/carbonfiber-alufoil-selfmade-diy-battery-with-naco3-or-ashwater-electrolyte So these carbon fiber sheets are…

Epsom salt, MnO2, and Carbon rechargeable battery

This is a homemade rechargeable battery that uses Epsom salt (magnesium sulfate), manganese dioxide, and water. The electrodes are both carbon rods out of a D cell zinc/ carbon battery. The MnO2 was obtained…

4 carbon fiber alufoil cells in series running LED

http://www.overunity.com/13282/carbonfiber-alufoil-selfmade-diy-battery-with-naco3-or-ashwater-electrolyte Hi, this is a test with 4 carbon fiber alufoil cells in series running the LED chip. Unfortunately the inner resistance of these cells is tsill too high, so the light output in…
