Wouldn't you need more than two "cups" on a VAWT considering that when both are perpendicular to the wind it's going to want to try to spin backwards.......

And I think I've read either here or elsewhere(maybe Ed's place?) that if you're only using two cups you need to make a stack with two more on top 90 degrees apart thus that there's at least one cup pulling all the time.......

I think 3 blades would work better than two,
however I was under the impression that while
one 'cup' was facing the wind that is drag and
the other with it's other side is lift...much
like a sailboat can sail against the wind.
