E - mining's e- dumper worlds largest EV. The pack is 4.5 tons with 700 kWh https://insideevs.com/news/361095/edumper-largest-ev-world/ Able to regenerate enough energy with a full load on descent to enable the empty return trip uphill. Now THATS some regen!
after the first charge to get up the mountain, it's actually beyong a perpetual motion machine, as it actually charges MORE than it uses.
8% more charge every trip down and then they use the extra energy for factory operations, pretty smart.
Now that's being energy-efficient, and therefore cost-efficient! But I hate to praise a company that is -- I assume -- doing strip-mining or open-pit mining. Talk about environmental damage!
It's not a matter of where, it's a matter of how damaging to the environment the extraction method is. Traditional mining by tunneling is far less damaging. Of course, it's also more expensive per pound of yield, which is why open pit mining is so commonplace these days. A fee for environmental damage needs to be included into the cost of everything we buy. Hopefully the younger generations will start moving strongly in that direction, because our generation certainly isn't!
