An anonymous reader writes: At this year's Tour de France, thermal cameras and various other tools will be used to detect "mechanical doping." The image tests can be done anywhere and their locations will not be publicized, according to officials. NPR reports: "As far back as at least 2010, accusations have flown that elite cyclists were turning in superhuman performances with the help of motors that are hidden inside their bike's seat tube. Commercial versions of such devices can provide a steady power stream of around 200 watts -- the lower range of a pro cyclist's average output in a stage race. They can also be set to assist riders automatically if their pedaling cadence falls below a certain threshold. Tour de France officials explain how the detection system will work: 'Developed by the CEA (the French Atomic Energy Commission), the method consists of using a thermal imaging camera capable of detecting mechanical anomalies on the riders' bikes. The checks can be made in the race and on the side of the roads.'"
