- If the flywheel were made out of neutrinos then if it disintegrated the
- neutrinos would fly through the housing, the driver, the bystanders, and light
- years of lead with negligible interaction.
-
- Of course, the car would have to be equipped with a neutrino detector to tell
- the driver that his flywheel had disintegrated, especially if there are 20 of
- 'em, and that he has to go to a service station.
-
- Neutrino dectors weigh hundreds of tons and involve toxic substances like
- carbon tetrachloride. There's also the problem that YOUR neutrino detector
- would blip if either the sun went supernova or some OTHER driver's flywheel
- blew.
-
- Oh, well, back to the drawing board.
