This so-called solar wind sail
of the University of Bern was the only non-American experiment on board the Apollo 11.

The Electric solar wind sail
facilitated Manned Mars Initiative, EMMI, could provide a fundamentally new, economically sustainable way to approach manned Mars flights.
On 7 May 2013 at 5:06, the first mission to test technologies for the electric solar wind sail
, which up to that moment had been a purely theoretical concept, was launched on board the Europe's new launch vehicle Vega.
In 2009, Finnish researcher Sini Merikallio won for a proposal to deflect an asteroid (http://spacegeneration.org/images/stories/Projects/NEO/Sini_Merikallio.pdf) using an electric solar wind sail
Still feeling vulnerable, Brie joins the crew of the Maine Wind Sail
, and they quickly become family.
And the key insight that the makers of the first windmills must have had is that the wind can be harnessed to propel an object--a wind sail
or a sailboat--in many different directions, not just with the wind.
Another way of tapping solar wind momentum by using an electric sail is the electric solar wind sail
(E-sail) invented by Janhunen [5-9].

The scientific mission of ESTCube-1, the first Estonian satellite, is to perform an on-orbit test of the electric solar wind sail
A racing asymmetric spinnaker with a mid girth of aminimum 75% of the foot length measures as a regular down wind sail
. This means you can combine it with your regular spinnakers without penalty within the ORCi and IRC rules.
