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.

No, I'm saying what I said and you're still a nitwit loon.


Making the Gravity Anomaly Glider does not have to be an aviation
record design.


In fact it does not have to be a design at all, given that it's a
preposterous notion.


It would be allowed to use helium lift
boosting and it could be unmanned.


If it's using "helium lift" than it's not a glider, you idiot.

The question becomes the restriction of wind conditions. Mybe
1 to 2 mph wind would be allowed. Takeoff would be with a
drop-able gas motor-propeller.

Balloonists likely have no notice of this anomaly because
it would be felt as a slow wind vector.

The basic test requirement is for the Glider to be heaver than air.

I have a design for an inflatable aircraft. It allows easy
rubber/pvc/plastic welding of the wing in perfect aerodynamic form.

My only need is to figure the exact airfoil form for it. Maybe
a flying wing also.


I think a unicorn would be nice...

Dougie, this is sci.space.policy, not
rec.aviation.rubegoldberg.nutter.

That's a cool idea you have there. Unfortunately it won't work.

No it wouldn't be felt as a slow wind vector. It merely changes
very slightly the direction of vertical. The atmosphere experiences
the same small offset of the direction of vertical, meaning that
air pressure decreases the most in a direction that is not quite
equal to the direction of the centre of the Earth. So instead of
falling towards the centre of Earth you fall in a direction a
little different that happens to be the direction of air pressure
decrease, like always. From the glider's point of view, the exact
position of the centre of Earth doesn't matter much. What is
important is the direction of gravitational verticality.

Note that the direction of gravitation verticality changes because
the world is somewhat a ball. So when you move around the direction
of the pull from Earth changes. That doesn't help the glider because
the direction of the decrease in air pressure is always the same as
the direction of gravitational verticality.
