When a strong wind such as a gale or hurricane blows, houses
are sometimes blown over.
A pair of masts mounted to the roof will have a sail apiece,
appropriately reefed for the conditions, booms angled such
that the house appears to be tacking into the wind. One sail
will be on a port tack
while the other is on a starboard tack,
with the combined effect pushing the house into the wind and
counteracting the blowing force.

"... but the fourth little pig put masts and sails on his house ... and nothing was seen or heard of him ever again. The End." |

Ah, no, it won't work that way. |
|
|
This concept could be applied to a sailboat, substituting a
boat for the house. Could be the first sailboat ever to sail
directly into the wind. |
|
|
Worth a try anyway. You can drive. |

No, that's Baked and WKTE. <link> |

So, put a windmill on the house, geared to catterpillar tracks in the basement...? |
|

[pocmloc] The concept was lifted from sailing somewhat
against the wind by angling your sails accordingly. If equal
and opposite sail angling were to occur would the resultant
force on the house be to push it against the wind, resisting
blow-over? |
|
|
Look st a diagram of how a sailing ship tacks into the wind. |
|
|
The geometry is relatively simple and vector addition shows that the vessel can travel at about 1.4 times te wind speed (square root of 2). |
|
|
If you have two masts on "opposite " tacks, the vector sum will not be zero normal to the direction of the wind; you'll just generate tension between the masts. |
|
|
The thing about tacking into the wind is that it needs a shear-
line that's up-sea of the quarter-point (which can be a
problem if you've left too little sea-room). Even then, luffing
on a lee tack will cause you to skew to larboard, even with a
full keel to the tideline. |
