Huh?

Sailboats are already solar powered. Where do you think wind comes from?

Following that line of argument -
EVERYTHING is solar, or star, powered.
Where do you think ANY energy source that anyone uses for anything
comes from ?
:-).

Anything above iron has, it is generally believed, been made in a star
mill - usually a Nova, less frequently a super nova.
Iron is star ash. Below Iron there are options as to sources.
Ultimately it all "just happened". The meaning of "just" here is hotly
debated :-).

There are NO energy "sources" - only energy converters from one form
of stored energy to another.

There is still a question of Polarity.
Are you saying that Chicago Sucks, or that
Chicago Blows?

Of course.

I was thinking that, paradoxically, the photovoltaic solar boat is
probably more polluting than a regular sailboat. The cells, wires,
electronics etc. have to be made somewhere, and eventually disposed.

Everybody knows that the wind comes from Washington DC.

Well yes, ultimately, but that goes steaming past the point!

The timescale is the important factor, not the source.  Nuclear fuel dates back to the creation of the stars, fossil fuels to the recent past of the Earth,
what we now call Solar is arriving now, and so is the only "renewable" energy source - all the others are a limited resource.  

For the long term (tens of thousands of years and more) the only viable solution is to use Solar in its various forms: collecting heat, photo-voltaic,
wind, waves, tidal, hydro.  Anything else will run out.

I believe it was "... star stuff ...", but, like him, I may be wrong.

NO, NO, NO!!!
It's from (Joni Mitchell? at) Woodstock:

I came upon a child of god
He was walking along the road
And I asked him, where are you going
And this he told me
I'm going on down to Yasgur's farm
going to join in a rock 'n roll band
going to camp out on the land
going to try an' get my soul free
We are stardust<------------------------------------------
We are golden
And we've got to get ourselves
Back to the garden

Then can I walk beside you
I have come here to lose the smog
And I feel to be a cog in something turning
Well maybe it is just the time of year
Or maybe it's the time of man
I don't know who l am
But you know life is for learning
We are stardust<-------------------------------------
We are golden
And we've got to get ourselves
Back to the garden

By the time we got to Woodstock
We were half a million strong
And everywhere there was song and celebration
And I dreamed I saw the bomber death planes
Riding shotgun in the sky
turning into butterflies
Above our nation
We are stardust<---------------------------------------
Billion year old carbon
We are golden
Caught in the devils bargain
And we've got to get ourselves
Back to the garden

Ah.... Good s*** man!!!

Indeed. It was written by Joni Mitchell in 1969 and released on the
album "Ladies Of The Canyon" in 1970 which also includes two of my
other favorite songs she's written/recorded -- "Big Yellow Taxi" and
"The Circle Game". Probably one of her best albums along with
"Court and Spark" (Help Me, Free Man in Paris).

And my favorite from her Blue album... "Carey".
Named for me of course.  Played it a lot that long, hot summer I was a
DJ at a tiny R&R station in SW Georgia (USA).

OK - makes at least as much sense as Carl Sagan did :-)

I was very upset with him dying so young. I was compiling a long list
of points I wanted to raise with him some day based on comments from
his various books and he up and died on me before I could point out to
him the various errors of his ways :-(.
