Recumbent trikes make a lot more sense than upright trikes to me.
Lowering the center of gravity has significant benefit on a multi-track
vehicle - a tadpole trike with a low seat handles like a go-cart.

I remember riding Grandma's trike a few decades back. You can't do
high-g corners on those things; they're too tippy. Ask me how I know. ;-)

Wind sails on Grandma's trike: fun but useless. All was fun until the
frame
developed a crack...

and mind is the best thing for us; but most people do all they can to
get rid of it, and as a general rule nobody does much more than
circumstances drive them to do. -Harriet Beecher Stowe, abolitionist and

Heck, RANS was building sail-trikes over three (3) decades ago:

Yikes! I'll have to look at that closer when I have more time.

About the same time we were doing it, I suppose. Let's see... we were
doing it sometime in the late 70s... I guess they beat us to it. And
theirs looks a whole lot better than ours did. And I can't imagine this
wasn't done at least 50 years before then.

First thoughts: Atrocious web site design. Several pieces overlay when
viewed with Firefox, and the fonts are minuscule when viewed in Internet
Exploder. One of the videos crashed each of these browsers.

The vehicle is kind of interesting, even though it doesn't look like a
"serious" vehicle. There are far too many gadgets, googaws, and
protruding bits that would be far too easy to break. The
sail is said to be about 13.5' high; who has a garage to fit that thing?
And the sail is right in front of the operator, obstructing his view. Scary.

All that said, I think it would be fun to pilot one of those for a while.
