Shape the roof right, make it height-adjustable and use Bernoulli to provide just the right windspeed all the time without recourse to fans etc. ![]() Wouldn't even want to blow off, just push itself down onto the ground/lake...

Yeah, but needs nice big heater elements in there to maintain that steady summer feeling.

'Like' So it'll need to be transparent too, for solar heating purposes.

And will block UV so it will be healthier too (apart from getting rickets of course!)

Got to make a careful choice of materials there. I recently looked it up and in the case of glass, I seem to recall, it blocks out the tanning UV wavelengths but allows other, harmful ones to pass - just what you don't want. Conservatory dwellers beware!

How high will the roof be? Just wondering if Thames A Rater sailors will be needing to stay away?
And will the downforce roof be able to turn so it is always facing the wind? I'm sure this roof will need to be made out of something more hitech than glass - carbon re-inforced clear polymer with built in photovoltaic cells. Alternatively, a lowtech giant version of one of those garden "sails"/awning that sail makers actually can make a profit from. |

I would say that it should be at least twice, probably three times the height of the tallest rig, otherwise you might start getting a reverse wind gradient at the top of the rig which would make setting the right twist on the sail extremely confusing |

We're certainly getting there with this idea.
Next step, funding - maybe one of Mr Putin's friends for the completeness of folly.

I was thinking Larry E might help - after all, it is wing shaped, and we know he likes wings.
Mind, we can sell the leccy we produce back to the National Grid, and make a profit that way. |
