I'm surprised that no one has brought up, literally and figuratively, the energy involved in making that big truck work "better" going downhill. Doesn't the description of the activity imply that elsewhere (top of the mountain) is a loader or loaders filling the vehicle up with potential energy? There would be payloaders, belt systems, some form of huge dispenser of mass creating or moving the material that has to be moved to the bottom.
As with water generated power, there has to be a source. In this case, the source is overlooked, but that's okay. Also, there's no reference to inherent efficiency losses. That aspect is all too often ignored, especially from people who tell me I should build a generator into my spare tire and run it while I drive, to recharge my battery pack! I'm sure everyone here recognizes that there is still a net loss and in the case of the loading equipment, I'll venture to guess that it's a severe net loss. fred -------------- next part -------------- An HTML attachment was scrubbed...
