Well, I have never met "a new energy source" either. Does this mean I
can now dismiss all possibilities and go out into the world preaching
that all sources of energy have now been discovered and we are doomed?

Funny, where I come from, logic just doesn't work like that ...

Just because God knows how everything will turn out, doesn't mean our
choises are of no value.

I don't know where you are getting your ideas, but since the subject is
changed again:

I would like to see a new energy source. I have some doubt I will find it
on YouTube, but those chances are greater than if I built it out of my junk
box. Such things will likely come at great expense. My solar experiments
only account for a small percentage of my electric usage but I have managed
to cut my gas bill drastically. Some could argue it is the oldest energy
source out there. Everyday we are bombarded by a whole lot of energy that
just heats up the roof. I have cut my bill by simply putting to use the
energy that would have only heated up my roof or my South side.

The point is we should all be thinking about such things rather than
expecting some government "fall guy" to fix it for us by digging deeper into
our pockets for "party money". What we have when we foist our
responsibilities on the government, are big screwups by people who are too
removed from the problem to have a hope to fix anything by throwing money on
scam artists. The Castro government comes to mind as a perfect example.
Just throw money at the government and it becomes fat, and lazy and a burden
to those who see a need and fulfill it. The job of a President should be to
inspire rather than shoulder incessant ridicule that cripples our nation's
credibility in the world. Those who ridicule should stop and provide some
useful input or shoulder responsibility themselves rather than hoping for
disaster to vindicate their bad attitude.

If we ever do find a race of aliens, I would hope we would hear from them by
radio first. There is no reason to think there couldn't be, but if they
were close enough for it to matter, we should have heard from them by now.

Unless they consider on-off keying (or radio in general) to be obsolete,
beneath them, and hate everyone who uses it because they won't waste their
time learning it, then look out.

Since our subject is still baluns, I have used Fiberglass tape on Torroids
and solenoid windings because they heat up. Other things deteriorate. I
use that because I have some. I couldn't tell anyone what would be best in
the long run for UV. It is a big problem. Heat means loss. I prefer to do
away with the need for baluns and other elements that don't contribute to
radiating the energy.
