Compared to a real airplane, yes.

There may be some niche applications, like unmanned surveillance, where they
might be useful but they are terribly fragile.

And a range of 90 minutes....
That's barely enough to start a crosscountry.
If you want a fun machine that goes places cheaply
The Bantam B22 Microlight has a 4 hour range at 60+ knots.

I was referring to the unmanned research things that stay up for days, mostly
because they are little more than gliders covered with solar cells with an
electric motor.

Correct. Those are aeronautical physics experiments.

They are unmanned to set records in duration and elevation.
They also have the "electric advantage" of no oxygen requirement.

An LSA manned electric plane has the "no oxygen advantage" too.

LOL! And anybody can perform the FAA modifications on one.

No they are unmanned because they would have to be many times bigger to
carry the weight of a person.

snip nonsense

No they are unmanned because they didn't want to make
them large enough to carry a man.

Keep trying. Even a blind pig gets an acorn once in a while.

I AM WRONG! They aren't unmanned because they didn't want
to make them large enough to carry a man.

I AM RIGHT! See my first answer. They are unmanned because
they wanted to set endurance and elevation records.

My mistake was in thinking I was wrong.

Like you.

Having comprehension problems?

If you want to be 100% anal-retentively correct, there was never any plan
for them to be other than unmanned, so they were designed to be just big
enough to be able to fly with what's in them.

No I am not. You are!

Wrong, wrong, wrong, wrong, wrong

If you study the development of the design and it's mission
statement, you will see that these things are designed to
carry nearly an 800lb payload. Further study will explain
what that payload consists of, and what it will be used for.

No acorn for you.

Actually you could carry 2 or 3 people. They are unmanned to set
records in duration and elevation.

"Payload: Up to 726 lb., including ballast, instrumentation,
experiments and a supplemental electrical energy system..."

Where would you put them, strapped across the wing?

"Payload: Up to 726 lb., including ballast, instrumentation,

Or in other words, it was already full of junk.

BTW, this text isn't in your link.
