Default Beamed Energy Propulsion

Here is a NASA report on Beamed Energy Propulsion.

https://ntrs.nasa.gov/archive/nasa/c...0150010986.pdf

I have a variation on this modality of rocket engine.
While the rocket is first climbing through the lower atmosphere
there will be significant air gas to run a Magnetohydrodynamic
(MHD) engine. The high power beam is focused on the ionization
chamber of the engine. The fuel becomes ionized air.

To drive the MHD magnet there is a simple solar cell electric
system.

As the rocket enters rarefied air level there needs to be
a change to a pressurized gas canister for fuel. Just use
something like CarbonDioxide.

It will obviously be a small rocket mass system, but it will work.

No you don't. What you have is something different that won't work,
as is usual for your 'inventions'.

There's nothing 'simple' about hanging a huge solar array on a vehicle
you're trying to drive through dense air.

It won't work and for the same reason every other MHD rocket engine is
impractical; insufficient thrust for the mass of the vehicle. You've
added the complication of wanting to hang large solar arrays out where
you have to drive them through the air without breaking them off.
