If you would like to see a use for old rotors, go to Mechanically scanned LED clock built into a Wankel rotor on You Tube. Fell free to add negative comments as moose will appreciate them.John Berry
Incidently, Moose makes the electronic ignitions units now available, so if you have problems with them add comments here and I'll be more than happy to pass them on. Everything he makes has a glitch, "Glith UK"!
Looks . Would have been better if it was fixed on the primary drive end of a spinning rotor shaft. Admittedly it would need a big display shelf and would cost more than the average clock to run. And it would make more noise. And cooling might be a problem too. Minor problems aside though, it could have a lot going for it!Johnny.
