Looks kinda interesting
=========================

Not just fairly large, might be a record at what looks like 7 or 8
actual hp, translating to maybe 700 or 800 pounds of thrust. None of
this wimpy Minn Kota stuff for sure.

That's the good news. The bad news is that it will need 8 VERY LARGE
6 volt batteries to power it for even an hour. The only batteries
commonly available that might do the job are the heavy duty L16s,
running about 110 pounds each. So, for about 900 pounds of battery
weight you could tool around for maybe an hour, quite possibly less.
Not likely you will be on plane. If you want to run all day nothing
less than a hydrogen fuel cell, nuclear power or an acre of solar
panels will do.
