Well for a country why thinks Thai electricity is different to Western ectricity and there is no need for earthing of power systems and the floor drainage is always at the highest point of the floor because high water can run up hill, the answer is nothing (can go wrong).
Now we understand why there are no engines ordered for their next bunch of Chinese subs apparently on order, they are well ahead of the game and could foresee that electric was the way forward... ????
But bear in mind, some people are a rse holes, and couldn't care less about anyone other than themselves and probably the very first to expect someone else to get them out of trouble if it every arises.
