Wrong comparison. D-cell powered toys are typically doing
significant work. On the other hand, small induction motors that
do nothing but rotate do *not* run down a small battery in an hour or so.
I cannot see YouTube from my office so I do not know how big the
machine is or how much noise it makes. I was guessing based on the
schematic (and the size of the D battery in it) and the photo shown at ZDnet.
If the thing is as quiet and smoothly running as an analog clock
then of course it can run for weeks or months on a D battery. I was
kind of assuming that it was making a lot of noise, wind, and
commotion, like a small toy.
Actually, it could run for years, perhaps. Clocks do run for years
from a single AA cell.
The point is that, so far, no demonstration that is remotely
convincing. Just a peek at a claim that this machine is a
demonstration of the technology.
Looked up Bedini. Interesting. Yeah, could be a Bedini motor. Which
is patented already by Mr. Bedini. It didn't claim over unity in the
patent, just the method of alternating discharge and charge cycles
from a motor-generator, if I read it right. However, Bedini claims to
have a motor which has run for many years, single battery....
Maybe so. That's not impossible, nor does it contradict the laws of
physics. Except Bedini says it does. What's the basis for that? Well,
not stated, as far as I could see. The theory wasn't intelligible to
me, but I'm not really interested in the theory. I'm interested in
the basis for an over-unity claim, and that a motor runs for a long
time doesn't establish that, it merely creates some kind of an
appearance, if we have certain prejudices about how long a motor
could run on a battery! Might be a long time, depending on the motor
and the battery and how they interact!
The Bedini motor had a fan on it, which would presumably create some
drag .... so .... that's certainly more interesting if it actually
ran for years. Did it? Well, how many of these are there and how many
have observed this kind of result? What kinds of witnesses are there?
Who are those who testify to it? It makes a difference....
