The R8 radial EHD engine

(Neil McPherson)
Here are the photos and some technical information on the R8 radial EHD engine.
It has 8/6 cm aluminum foil cones attached around a central hub. The outside
diameter of the engine is 28cm. The R8 travels at approx .7 meters per second.
Lightweight construction materials used are plastic drinking cups for the Hub,
plastic drinking straws for the shaft and struts, aluminum foil for the cone
shaped positive electrode, and 3mm magnesium strips for the negative or earthed
electrodes attached to the cones by cardboard. The 8 positive cones are fed
power from a single point on the shaft at the rear. The 8 negative or earthed
electrodes are attached to a single point the front of the shaft. There is also
an extra positive aluminum electrode on the Hub. Power source is 28kv from an
old computer monitor. For any further technical information, see JLN
Labs EHD engines.
Be careful when using these electrical devices.
Good experimenting
