infra red leds

 I was wondering if infra red leds could heat water as they operate at 100
degrees C.  Sorry I have no science.  My other question was pendulums.
Could you get a massive swinging pendulum and power tools, washing machine
and charge batteries that way ?

No power in LEDs.  That's why the batteries running them lasts SO
long.

The pendulum doesn't make power.  In the Science and Industry Museum,
in Chicago, way back in the 1960's, there was a huge pendulum as high
as the building.  It was calibrated to be a clock and to show earth's
rotation.  I forget how many tons it weighed but it was a LOT.

I was there just at the right time to see it "wound" one time.  All
the power to run the pendulum clock for the next 24 hours was put into
it at that time.  It's certainly not perpetual motion.  The resistance
of the air running slowly by the huge weight on the long, long piano
string was enough to stop it.

A pendulum winder on a wrist watch doesn't wind the watch, either.  It
merely holds steady while the swinging wrist it's attached to winds
the watch.

The Cherry 3000 is an Android built starting in 2727 to augment the
depleted supply of FHBEs after the Reptillian Invasion. Although the
replacements were not perfect they did as they were commanded and did
not talk back to their masters.(sorta like a young compliant Barbara Eden)
