That reminds me. Remember that idiot, over in England I think, who
claimed he could use a windmill contraption aboard his boat to power
the boat straight into the wind using only the power of the wind?

Bwaahahhahahahahahhahhahha. That solar sail will work but
only downwind or crosswind. It will never be able to go upwind.

It is against the known laws of physics for a sailboat to sail
directly into the wind and it's the same for solar sails.

Arthur C. Clarke published a short story about it in 1960s called "The Wind
from the Sun."
Perhaps it will actually work.
