Norway I believe it was has also had energy positive mining trains for awhile as they mine up in the mountains, load it up, and bring it down to the coast using electric generators for brakes.
- looofooo0 1y agoI wonder that in certain parts of the world, the train network could become net positive electrical contributor by mining stones in quarries up the mountain? https://www.youtube.com/watch?v=VVaWmEI9O1w https://www.youtube.com/watch?v=VVaWmEI9O1w
- eru 1y agoDepends on what you measure, I guess? Ie I don't think you have enough excess energy to pay for the actual quarrying itself. (Though you might be able to become energy positive if you take water as a ballast, not stone. Water is easier to pump into some tanks.)
- looofooo0 1y agoWell inner mine transport can be net positive as well with electrical mining trucks. Then you need the energy for explosives and stone cutting, which needs further investigation, whether this can be offset by the energy gained of the stones travelling downhill. Water should be better used for hydroelectrical production.
- eru 1y ago> Water should be better used for hydroelectrical production. Well, putting water on a downhill train _is_ hydroelectrical production. Just a very cumbersome way. The stone could be called lithoelectrical production.
