I am looking for the name of the company or manufacturer which
provided the propulsion system for the Mars rover.

There have been several Mars rovers. Which one are you speaking of?

I honestly do not know, because, I am following a very limited lead
which doesn't offer much info unless I lay down an annual thousand
samjack dollars to find out. I do know that the same company is big
into hybrid powered sailboats, and a possible patent
infringement/lawsuit against a major auto maker that is unlawfully
using the technology -- it appears to be all hush hush, but I am
guessing the said company of infringement is either Toyota, or
possibly Honda.

I am rather new to this whole Google answer business, thus and
therefor, I am cheap in my price offering. I usually crack the info

I also know that the company is American based. Likely in Florida, and
sells for under a buck.

My feathers are wet, and I just thought I would give this avenue of
information seeking a whirl.

My appologies if I am off in left field.

Possibly your company could be Solomon Technologies, which has been
invoved both with the Mars rover and with the boating industry. What
do you think?

"NASA used a simplified version of the Electric Wheel in the Sojourner
Mars rover and has supported its development since 1994 through its
Mid-Atlantic Technology Center in Pittsburgh. 'The Electric Wheel,'
said former NASA Administrator Daniel Goldin 'has application to
everything that moves.' NASA approached Solomon Technologies first to
offer help after learning about the Electric Wheel through a patent
search. After considering the full Electric Wheel for the Sojourner
Mars rover, NASA adapted Solomon Technologies' revolutionary
technology to the rover's limited speed and light weight requirements.
The result was a single motor version with planetary gear set in each
wheel to power the rover. In return for the rights to use the patented
technology in the rover and other space vehicles, NASA set up an
Electric Wheel Working Group with engineers from universities,
government research centers and private industry. With the Working
Group's help, Solomon Technologies has been able to test and refine
the system and establish cost-effective manufacturing procedures.

To further advance marine propulsion for the ever-expanding boating
industry, we developed a line of single- and dual rotor/stator drive
motors without the integral transmission."

Solomon Technologies (mentioned above) has been involved in a patent
infrigement lawsuit against Toyota:
There is no answer at this time.

The current pair of Mars rovers, Spirit & Opportunity, each carry 39
electric motors for the various systems, including the wheels used for
cross-country travel. The motors on these probes were manufactured by
Maxon Motor USA.

Wow, nice work. I will look into it right after I get done feeling
stupid for missing it.
