18 - 1,8 = 16,2 км/ч - собственная скорость катера.
16,2 - 1,8 = 14,4 км/ч - скорость против течения реки.

36-year-old Canadian film-maker Rob Spence doesn't seem unusual.You wouldn't realise it at first, but one of his eyes is false. But this is not the most unusual thing about him. Inside this false eye Spence has a wireless video camera. This camera is not connected to his brain and has not improved his eyesight. Instead it records everything he sees. The camera runs on a very small battery and it has a transmitter, a device which allows Spence to send an image of what he is seeing at any moment to a computer.
Spence damaged his right eye at the age of thirteen while he was playing with his grandfather's gun on a visit to Ireland. After the accident his vision got worse until he became completely blind in that eye. Three years ago, he had an operation to remove this eye and to insert a false one. And it is this false eye that now contains his miniature video camera.
Spence knew that building a camera that was small enough to fit inside the eye would not be easy, so he contacted Dr Steve Mann, a cyborgs scientist at the University of Toronto. Cyborgs are machines that combine natural and artificial systems. Together, Spence and Mann succeeded in building a device which Time magazine described as one of the best inventions of the year.
Even though his project is still quite new, Spence says that many people have already told him that they don't like being filmed. He finds this strange as the same people have no problem with the hundreds of surveillance cameras that film them every day at school, in the underground and in shopping centres. He hopes that his project will make people think more about how governments and organisations monitor these cameras and the information they record.
