On a rather less flippant note, they are relying on Kevlar, which is claimed to have five times the mechanical strength to weight ratio of steel. What is known about its fatigue performance? Can it be made free of defects over great lengths? Bear in mind that one microcrack in 5,000 metres means destruction of the whole system. Megawatts pouring into a discharge channel of the order of a centimetre in length is not a spark, it is an explosion. |
