The energyfromair link doesn't work for me -- complains my version of
Internet Explorer is too old (I'm using FireFox 1.5.0.4 -- somehow I
don't think upgrading would help...)
The first link is a tad strange. The string on a pendulum doesn't
really do any work, save to the extent that it stretches and contracts
slightly as the force on it changes -- its pull is perpendicular to the
line of motion. All the energy comes from the initial push. The
statement "This increased tension will do work against gravity" seems
odd; the energy-in is from the initial push, after all...
There are a number of people "out there" these days who feel Newton took
a wrong turn and all of science since his time has been a confused mess
because of this. (Some of them are regular posters on
sci.physics.relativity, which is where I've run across this particular
point of view.) Sounds like M. Kin and Tseung may be in that camp.
