Default Magnetohydrodynamic Space Drive

On of my concepts is to use the solar corona gas as fuel for
a true space drive. I looked at the topic and found that
records, wiki, call it impractical.

I will point out that plasma production energy costs appear
the cause of impracticality. My space drive is designed to use
free coronal plasma as the fuel.

It also warns of heating of the interior "chute" causes
loss of physical integrity. I would use a suffiecient
ablative ceramic, nonconductive, to line the central plasma chute.

Given free plasma allows a huge gain in efficiency. It
is to be a cometary ejection form of orbit to free interstellar
space.

The energy source to make a magnetic field is quite obvious
high temperature solar cells.

Why do I bother?

Seems like if your talking about "magnetohydrodynamic", you could also include geoengineering an asteroid or small moon for artificial Van Allen, then rejuvenate the small body via what Carl Sagan suggested

better than that. Pretend the Rocky Mountains are a plate like
asteroid and calculate the gravity pull at a disk edge like geometry.
Then calculate the earths gravity for a Rocky Mountain free Earth.
Pretend you are at Boulder Colorado. Now add the asteroid gravity
vector.

Now we have an obvious gravity anomaly.

The question. What type of glider design can fly using this horizontal
Rocky Mountain gravity vector?

Gravity doesn't work like that.

Are you saying an asteroid has no gravity? My anomaly is
stated using an allowed two body system. If the asteroid
was just overhead would its gravity pull cause a net change
in total pull?

In my thinking why would we be restricted to overhead
vector two body system?

Newton's gravity is a spherical geometry theory. How
would you calculate a disk asteroid gravity map?

Remember mass does not attenuate another mass's gravity
field, you can literally use a set of small spheres
filling the sphere of Earth to estimate Earths gravity
pull. The same goes for a disk asteroid.
