- AARRGGGHHH!
-
- Flame on.
-
- The rampant idiocy on flywheels just continues. How many ways do people have
- to be told about conservation of energy?
-
- Don't contribute to the discussion if you don't know anything and haven't
- at least read a few articles in it, for cryin' out loud. I figure there's
- been about 1 post every 4 or 5 hours over the past week or so, on average,
- refuting this lunacy about "fluff".
-
- Get it through your thick head - energy is conserved. A flywheel that can power
- a car for 600 miles stores basically the same energy that gasoline to power it
- the same distance contains. Do you know anything about fuel-air bombs? Do you
- realize how big an explosion a few gallons of gas can make, when properly mixed
- with air? Do you realize that a hyper speed flywheel fails in microseconds,
- releasing all that energy at once?
-
- You think fluff is harmless? Let's tie you down and hit you with "fluff"
- traveling at several km/s and at a temperature of a few thousand degrees.
- Let's see if we can find any teeny parts of you after the impact.
-
- Fluff falling out of an attic, indeed.
-
- I'm really tiring of this nonsense, so while I politely corrected the
- first posters in their misconceptions - you get flamed, boy.

- Good thing - they're pretty damned stupid for anyone else.
