In this case, I was referring to areal density. Plant a forrest or a wheat field
and use it to capture and store the energy. However, I intended this to be used
as a model, not used directly. That is, we can design nanomachinery that uses
sunlight to drive biochemical reactions, storing the result locally. Also
note that the whole mass of the maple tree represents a very large amount
of stored energy. If this isn't dense storage, what is?

Since I think that nanotech results immediately in the SI and in the ability
to self-augment, I feel that the nano-forrest is an extension of the SI.
Note that the SI may be collaborative, with each member of the community
being an extended human mentality. If so, I may choose to be (or include
within myself) a nano-forrest. Thus, the issue of constraining self-replicating
nanites doesn't arise. All of my nanites are highly specialized. Only the
forrest as a whole (i.e. I) can extend the forrest. Please note that I will
attempt to find a way to design and use novel reactions to capture a higher
percentage of the sunlight than a plant does.
