Except for the problems associated with dealing with solid, enormously
compressed (you keep going on about "metallic") cryogenic hydrogen and
oxygen, which you're not going to be able to work with at anything close
to atmospheric pressures.

How heavy do you seriously expect your fuel and oxidizer tankage is
going to be if you plan on using it out on the highway?

http://en.wikipedia.org/wiki/Metallic_hydrogen

Metalic hydrogen has already been produced in the lab.

Did you even *read* the article? That the initial theoretical SWAG for
the pressure needed to get hydrogen to change phase to the metallic
state was 250K atmospheres ( ~ 25GPa)?

And that that guess was off by a factor of about four?

Where are you going to get tanks to hold your hydrogen at a million
atmospheres (~ 100GPa)?

There is some good news, though; it is thought that you might be able to
get metallic hydrogen in a liquid state around 4 million atmosperes (~
400GPa).

How much is *that* tank going to weigh? Because if the pressure drops,
your metallic hydrogen isn't.

Come to think on it, are you thinking about using solid hydrogen and
oxygen when you say "metallic"? Still not going to be easy to work with.

I happen to think we are entering into a new age of physics where
things that were once thought impossible will become known
technologies.

Dark matter? You mean to tell me there is ANOTHER form of matter in
the universe which we know absolutely NOTHING about?

It will be interesting to see if it interacts with normal matter in any
way other than by gravitation.

There is plenty of stuff we don't know. Phase changing hydrogen and
oxygen to metastable states for use as I described may be among the
things we don't know how to do. As I mentioned in my previous posts,
we have to RESEARCH these things to learn how to do them.

Various and sundry have been working on it for at least 70 years.

You take what is known today and say it is impossible. People that do
that are usually proven short sighted.
