From the Discover page: "Every year our lasers travel about 2 million kilometers." That calculates to 228 km/h, which seems impossible, unless you are reporting the total distance travelled by all your lasers added together. However, the wording you chose implies that each laser travels that distance individually. Compare: "Every day the cells in your body travel about 2 billion kilometers". This statement sounds very strange, but is technically correct (more or less) if you add up the distances travelled by each cell. Still a cool factoid though :)
