I'll bet that cement has to then be pumped back out somewhere. If it's downhill again, great!
Why, it’s a perpetual motion machine.
Shhh! AOC will sue you for stealing her plan!
I’m guessing the writer was not a science major.
Clearly a safe bet.
In that case, you fill the tank with unicorn farts and liberal wishes.
They are using the gravitational potential energy of rock they want at a lower elevation to charge batteries.
And you had to spoil it for the rest of us that seldom read the article!!
But fortunately, most of us also skipped your comment looking for the pictures.
They could just as easily toss the rocks off the side of the cliff.
That would surely be a serious OSHA violation?
Don’t forget the massive amount of heat those brakes generate while going down hill ...
Maybe not?
The idea with regenerative braking is to seldom use the friction brakes. The wheels are turning a generator converting most of the mechanical energy to charge the battery.
Typically the friction brakes only activate at low speeds and panic stops.
What a waste of money for just that purpose, if true.
Unlikely that was the main intent.
Newer earthmoving equipment uses electric drive motors for better control and longer service life.
Those 22,000 gallons of diesel that are not being used should not simply be counted in units of liquid measurement, but in oil industry jobs that are lost.
Probably not.
Now the nutty nazis at VW wiping out diesel cars as we know them! That is a big deal.
A total of 172 billion gallons of fuel were consumed by (US)vehicles in 2009. Of this total 137 billion gallons (80 percent) are gasoline and the remaining 35 billion gallons (20 percent) are special fuels such as diesel.

Range is limited. Though Measured in decades before midlife refueling.
Wow! The Swiss have invented a perpetual motion machine!!
World’s largest EV: USS Gerald R. Ford
NICE!!!
If you are a Navy guy, maybe you can help.
After a ship crosses the equator, can’t they simply coast downhill to the Antartic?
Shellback power!
I don’t think so.
Similar to train locomotives using the motors to brake and the power is bled off as heat.
Now this one is more like my wife’s Privus V:

So what happens when the rocks are below the grade? Then is a power source needed?
BIG TIME!!!
This is brilliant!
They use the weight of a full truck going downhill to charge the batteries so the lightweight empty vehicle can ride back up!
Dino !
Yes, but too much downtime feeding and cleaning up the droppings.
And millions of little plastic bags!
Homeschool your kids!
So, how many mines in the world are at the TOP of a mountain?
At the least this one?
I have often heard the Climax mine near Leadville Co. removed entire mountain for the molybdenum. Starting at the top, could have worked?
Not 100% but deep pits like the Udachny diamond mine would have some return.
