Another possible path?

P.S. I didn't realize I had started the thread with this company.

This thread has come full-circle, that's the RV in the post that started this thread.

So this should diffuse any suggestion that electric motors lack torque or power.


True, but if you look a bit lower at the locomotives chassis you’ll also find several HUGE fuel tanks full of diesel…Critical thinking sometimes Required…

That system is used in place of enormous transmissions and clutches.


And your point is?


Read it again, maybe you didn't catch the reason for that type of transmission. Those "powerful" electric motors are there to transmit power developed elsewhere, just like those in any electric vehicle.

Sometimes a different perspective is required... Can you point to the fuel tanks on this freight train?

LOL [emoticon] Just because you don’t SEE the fuel tanks doesn’t mean they don’t exist elsewhere (outta sight, outta mind!) - and therein lies the grand EV gimmickry…

Oh, I don't discount the leverage magic that gears/winches/differentials/transmissions provide...just pointing that electric motors are preferred over ICE in certain commercial applications (including trains).

And yes, the outrageous power density required for the battery packs to power locomotive electric motors is a giant challenge. And then the hurdle of obtaining sufficient power generation abilities from hydro/solar/wind sources to charge said batteries. And don't get me going about how wrong Thacker Pass open mining operations for lithium is for the environment and the area's indigenous peoples.

All in the name of "climate change".....(shakes head).

EV's are greener than fossil fuel powered cars, even when the power comes from coal

But as the nation shifts to renewable energy, electrical powered transportation becomes greener during that shift. In my state, over half of our power comes from renewables.

Electric locomotives also gain efficiency for the same reason that EV's and Hybrids do -- they can use regenerative braking and send power that would otherwise be wasted back into the grid.

At best, a Forbes Opinion writer (or any other cherry picked ‘green theologian’) merely offers his anecdotal account repeat with bias (opinion is bias) in no way a substitute for objective empirical independent study…Before adopting such policies, where’s the independent peer reviewed study??

Don't pretend you'd accept peer reviewed research when you'll just dismiss it with "Be advised that Universities routinely compete for Gov’t Grant moola ($$ cash cow) by willingly contracting to substantiate what’s often and essential a politically preordained outcome"

Where's your peer reviewed research backing your claims?
