What do you admire most about Zhuge Liang?

What I admire most is that he can invent crossbows, Kongming lanterns and so on. It is a great loss for the Chinese nation that such a great physicist should go into politics. There is also the "wooden ox flowing horse", which is really amazing if it exists. Anyway, I don't understand what its energy source is. This will be the third perpetual motion machine of wood and wood, which will solve the energy problem of all mankind at one time. What kind of oil, combustible ice is weak, and horses can run without eating, drinking, burning oil, drying or charging. How high is this GDP?
