dan if i remember right i do believe that there was a device that had a big
weighted flywheel on it and once you spun it it would spin for a day under
it's own power
hmm henry ford museum ????

That's still not a perpetual motion machine, that's just a flywheel. It
stops spinning after a day.. If it kept spinning forever, then you got
something there.

Use to be a couple trolls in here who came damn close to perpetual spinning

A flywheel is not a perpetual-motion machine and does not spin "under its
own power", because it doesn't generate any power.

However they can provide bursts of power from the energy stored in the
battery. Then that energy loss (in the battery) is made up over a
period of time later by the alternator (with some lower increased load
on the alternator during the burst). So in theory they can provide
bursts of power greater than without them, but not sustained (hence
Dan's perpetual motion comment).

This does not mean I buy into this fan blower thing as a useful device.

....and it is possible that the extra power supplied by forcing a higher
air/fuel charge density will be more than the extra electrical load. A
turbocharger does the same thing by stealing power off of the exhaust -
but the amount it steals is less than that gained (but it's not free -
it costs in more fuel being crammed in - again - no perpetual motion).
Even more fuel costs come into play too due to the inefficiency losses
of the alternator.

....but if you fitted it to a car you would probably notice a gyroscopic
effect of some kind!

Do you think it could be a useful device with the new 42 volt electrical
systems?

A turbocharger "steals" power off the exhaust?????
WOW!!!!!!!!!!

>-
>but the amount it steals is less than that gained (but it's not free -


DOUBLE WOW!!!!!!!!!!

>it costs in more fuel being crammed in -


TRIPLE WOW!!!!!!!!!!!
I half way thought this guy actually knew something when he posted initially,
now turbochargers "stealing" power from the exhaust
What's next, UFO's "stealing" power from high voltage lines?????
