The article says it all...

Now get ready to produce them by the thousands.

Barney I have to tell you I have tons of respect for you just for your continuing to try to educate us. We have tried to intervene and inform you though that you have completely killed sympathy for your cause by going on with all of this crap even though no one seems to care... but I will continue to follow along for my daily giggles if no one else will.

Sooooooooo... how much does the 500 mileage range drop for this pile of junk on a sustained 5% grade for long pulls such as those found in the Rockies...? Or the area I live in where the “good” roads run 8-10 percent grades? Please provide specifications... I looked but could not find it.

I'd like to see the results after they load bagged benzonite up to weight limit in Lovell,Wyoming & then drive east on Rt 14A...
Grades are not just a hump in the road.... 8% for several miles,then !0% for several miles,Then 12% for some more miles....
How will the battery state of charge look after 50 miles of that ?

Or the many miles of grueling uphill climb on I80 driving east from Sacramento ....

I want to see results after the truck has done a climb of MANY miles..... not the humps like we have here in the east where going down would recharge .

I remember specifically on hiway 212 out of Yellowstone that it was 13 miles uphill with no level spot. Awful pretty scenery to look at if the truck quits though

Maybe someday they will come up with something that will work. I doubt that time is now though.

The 1997 Volvo 770 with 500HP Detroit Series 60,1550 ft lbs of torque,13 speed tranny,3.70 rears,lo=pro 24.5 rubber did the job quite well for me.

I'm all for developing new ideas for the time they may become viable, decades later.

I personally have two problems/ questions with "Teslafication".

1. Where is all the public subsidy money going to come from in a severely debt ridden nation. Corporate/Banking/Wall Street America is only interested in playing in speculations with the trillions it has.

2. Where is all the non-renewable, Lithium going to come from? There are multiple small sources now, mostly from processing brine pools and a little from mining. Afghanistan is said to loaded with it, but they're hard to deal with.

Good question. But what goes up must come down. Any guess what percentage of recharging will occur going down the other side? Something less than 100%, but is it 25%, 60%, 80%, or what?

Kansas would be a good market ...

From the article, the trucks will go from Sparks, NV to Fremont, CA.
Sparks elevation above sea level is 4,400 feet. Fremont 56 feet. Distance 250 miles or so.
Easy first test.
Don't get me wrong, I like the idea of electric vehicles. I don't understand why the cars are so pricey, though. Batteries cost money, yes, but look at all the other ICE components that aren't needed.

Up & down is the usual way of cross country roads... but as i mentioned,there are some where the uphill battle is many miles,some hours of climbing with little to no level or downward grade.That is where i would like to see the test performed.
I mentioned the grueling climb eastbound on I80 out of Sacramento...that climb will drive transmission oil temperatures upward into the danger zone... what will it do to electric motors ?
Yes,i too would like to see electric driven stuff... i just don't think they have proven things enough to turn semi's into electric.

Start smaller... lawn & garden equipment would be a very good place to start.

4400' to56'= LOTS of downhill driving.... how about a fully weighted load back UP that route... 250 miles is like local running to a semi ,where trips can easily be 650 miles or even 1200 miles or more.

They already did the lawn and garden thing over 55 years ago with the elek-trak

GE tractor line. They used primitive relays and lead acid battery technology and

worked real well within the load level the batteries could provide.

They have to build and use them to see if electric trucks will be viable. Time will tell. 500-300 mile range limits it's usefulness. It better recharge relatively fast and weight has to be comperable to a diesel. You have to start somewhere.

I am fully aware of those, i worked for a New Idea farm equipment dealer who sold the New Idea version of them.

Where is the modern,updated version of those tractors ?

The Telsa version.

Electric powertrain components are well proven, it is the method of supplying the power that is different with the Tesla trucks. Diesel electric locomotives have been pulling coal trains through the mountains for decades. Caterpillar has electric drive dozers, etc.

Well,lets see how well the batteries work,& don't forget,if the batteries go down in voltage in the middle of an uphill climb......

Then what... keep going on low voltage,that is always good for an electric motor..... i guess one could just stop on the hill & wait until the solar panel on the roof re-charges the batteries
