I'm particularly keen to avoid the requirement for high power, as I was
thinking to make this in such a way it can be shipped and powered up all
the time. If it could run from a few NiMH cells for 48 hours, that would
give the option of shipping it. I don't know if that's going over the top,
but it would be an interesting exercise.
