But what if the energy needed to cook your food in the dining car was the energy needed to brake the train, and there was only enough on board to do one or the other, which would you choose?

Thanks for letting us know where you are coming from "BigSky", shame we can't check out your RL credentials, you being anonymous, like B, but I appreciate you at least admitting what drives you, a wish to preserve your privilege.

I guess now you've made your booking in the dining car, you would be pretty pissed if the train didn't drive off the cliff after all, like I say it can be avoided, and probably will be avoided, if we know how to work with nature, it is actually much more clever than you might think.
