That ' s cool Adds a little extra that most Santas can ' t do and would make really a kids day <| sep |> interested to co me ak ch pc at 20 k 2 k ? <| sep |> Oh looks like someone didn ' t look at the voting demographics . AND Obama rallied a ton of minority voters , if hispanics and African Americans voted for someone who is actively trying to get rid of them then they have bigger issues to deal with . <| sep |> damn , you sure do know everything . <| sep |> As a sailor , i learned that if you can triangulate between two opposing differing forces you can go in a range of directions . So if the sail is set at an angle to the radial , you can go at an angle . The acceleration force that results is the vector sum of the impinging light and the reflected light . I . e . if the sail is at 45 degrees to the direction of the sunlight , the vehicle will experience an acceleration in the 22 . 5 degree direction , of 50 %. I don ' t recall exactly , it ' s hard to extrapolate from water to space . But in this way , the vehicle can actually go much faster than the wind , at the angular direction because the wind sail ' s radial speed is still less than the speed of the wind . There is a trade off between the apparent wind and the power that can be extracted , which is a simple fraction .
