Frankly, I think those coming up with new ideas will subscribe to the
second ...


We know that e = mc^2 All we need is a method
for conversion of ordinary mass into energy.

Cecil:

Absolutely!

However, I am much more interested in converting energy to matter.

Be nice to have a little machine in the backyard converting sunlight
into gold!

NO, I am NOT talking about gardening marijuana. grin

It will require more energy to turn the water into hydrogen and oxygen
than you'll get back when the hydrogen and oxygen are recombined. By any
method -- burning, in a fuel cell, whatever.


You can take that to the bank. Anyone claiming otherwise is ignorant,
delusional, a charlatan, or some combination of those. Anyone believing
it is sadly lacking in the most basic of science education.

Yep, but the ignorant will never realize or admit they are ignorant and
the snake oil salesman always has a job.

m = e/c^2 That would take a heck of a lot of sunlight.

OK. I suspect you correct.

DO do you think that Americans are not interested in experimenting any
more because
if anything new comes about that is usefull we can hire the engineers
from India
who have already done the research? Actually it seems that it has gone
beyond that
when you see the outcry against the Gaussian antenna or even boiling
water.
Do Americans really believe really believe that all is known and it is
a waste of time
to experiment? That if you are educated under the American system you
have the
ability to determine before hand what will work and what will not
work?
As an immigrant I was asked by the media the other day do I believe
that immigrants
that do the work that Americans wont do have a different aproach to
life?
I pointed him to read this newsgroup and make up his own mind , but I
also did tell
him to look up history to see how past Empires were lost, but I am not
sure
that he got my point

Hmmm. The first resonant peak of the
water molecule is around 1THz, while at
the microwave operating frequency of
2.45GHz there are no resonances of the
water molecule.

The 2.45GHz frequency has no particular
connection to the resonant frequencies
of candidate food molecules.

That would be why returns on 3 Cm marine radar are wiped out in heavy rain
then. I can vouch for the fact that heavy rain and spray can result in 100%
obscuration of ship radar targets.

Aircraft also use radar to detect storms. The severity of the weather ahead
is determined by analysis of the probable size of the water droplets in the
cloud, which affects the level of the radar return.

While water molecules may have an inherent resonance at 1 THz, it is
generally accepted by the scientific community that microwave ovens work by
exciting water molecules, amongst others, in food. I can't recall ever
cooking anything in a microwave that wasn't wet or at least damp. Well I
have tested some bits of plastic for suitability for use at RF, but that
wasn't for eating - and the wife was out!!!

I am happy to accept that there is no direct correlation between the
resonant frequency of a water molecule at 1 THz and a microwave oven
magnetron operating in the Ghz range. However, microwave ovens will heat
even distilled water quite effectively and heating is defined as an increase
in vibrational energy of molecules. So however the process actually works,
some principle of resonance must exist to allow the excitation of the water
molecules to occur. Either that, or microwave ovens actually work by heating
the food with infra red radiation derived using waste heat from the
magnetron and we have all been fooled. :-)

Well, your point is well taken here.

Correct. They want the news media to filter all for them, thus
relieving them of exercising mental muscle for themselves.

They rely on denying anything new is coming along until it already is
developed and accepted; then they claim they knew it all along.

You'd think them embarrassed over the above; but then, you'd be mistaken.

However, the gaussian antenna escapes me ... at least for the present
time. But, I don't want the news to filter you! GRIN

Increased molecular motion certainly
accompanies increased temperature, but
depending on the water's salt content,
the skin depth of water at microwave
oven frequencies is 0.5cm to 4.7cm. So I
guess it is an absorption phenomenon,
rather than resonance. Or, infrared
radiation from the maagnetron! ;-)

This information, BTW, comes from Ron
Schmitt's "Electromagnetics Explained".
