Tesla semi

[TemporaryKubotaOwnerMark]

Ironically Komatsu is working on a joint venture for a dump truck that generates electricity(Meet the E-dumper, the world's largest electric vehicle). However it's from hauling rock downhill so it doesn't violate any conservation of energy laws. Goes up empty and then generates electricity during braking on the downhill.

That's pretty slick! :thumbsup:

A coal fired truck...

Thats an old technology that has been used.

 

[Egon]

yes, running on the skinniest of low friction tires too...

Without diesel they are a no go.

Yup, battery cars dumped in 1800's.

100 years ago electric vehicles were the ticket...!

In 1910, Electric Cars Were the Best Vehicles on the Road. What Happened? | Inverse

Coming next month. This has always made sense to me because a big truck has the size and power to haul a lot of batteries around.
Now what about a high speed wind turbine on top? or somewhere...generate electricity while you drive down the interstate, help charge your batteries in
addition to the entire top of the trailer being solar panels one would assume.
Big long haul trucks average perhaps 500hp today. Let's assume the electric folks are going for the lighter weight loads to start.
So four 100 hp electric motors and 2500 torque. Instant torque. Half to be careful with loads and traction perhaps.

Everything will likely be automatic, trucks will move along in long adaptive cruise control controlled lines.
Until Larry Loser in the passing lane sees his exit while texting and rips across four lanes right in front of
Musk's giant moving battery powered truck. Then we'll see what safety tricks he has up his sleeve.
If you have seen the Youtube video of the newish Volvo semi stopping in a remarkably short space avoiding a collision
with a car that pulled right in front of them, you can tell there is a new day for big trucks coming. At least for the major operators.

If they can make the economic and ecological case for electric semis, I think we will start to see these on the highway.
Will guess that intercity will be first. Not like these things are going to fit in his supercharger setups he has already built; those are all regular parking spaces.
Somebody has to take the first step and Tesla seems to like that role. I just wonder when he is going to run out of money...his money
and ours. I hope he doesn't; what has been accomplished is remarkable.

Cab companies have gone hybrid and I think in some test cases plug in.

I don't think diesel is dead anytime soon, but how soon do you think you might be driving an electric truck?

Long lines of trucks? How about the electric trains already in service in Europe.

Wind turbine? Gonna eliminate all overpasses? Don't fit in with real physics.

Solar cells on vehicles? How much power would be generated at constant use?

Generation of electricity by wind and solar means will happen.

We have electric trains in service here too. They still need to be hooked to the electric grid. The Monorails at Disney are electric. Lots of subway trains are electric that is why you can’t touch the third rail.

Far as I know all modern trains are electric...just different ways of getting the juice...!

A quick Google search gave me a value of 265 watts from a 3x5 foot panel, for the sake of argument let's assume that is correct. One could fit 24 of them onto a 48' trailer, which would generate 6360 watts, about the output of a typical homeowner generator. Now imagine the same on railroad boxcars, only multiplied by 100 or better. Granted, they wouldn't produce enough to run the whole show, but they would generate power while stopped on the freeway for traffic or in the loading yard, or while switching cars at a siding. A long train could suck up nearly 800,000 watts, that's a fair amount of motive power.

One horsepower=745 watts. To put it in units which are more familiar, that 48' trailer could generate 8.5 HP and that long train might be 1,000 HP. Obviously not the sole source of power but not insignificant either.

Elon is just planting his flag on the hill with his new electric semi with 300 mile range.
He knows that there will be a quantum leap in battery technology in 3-5 years (maybe sooner) when lithium batteries with solid electrolyte go into mass production. These batteries will have at least three times the energy storage capacity of today's best lithium batteries that go into the Tesla vehicles. Then we'll see semis with range approaching 1000 miles and witness the introduction of over the road electric semis that will start platooning their way up and down the interstates.

They'll still be coal trucks, but with much worse production negative environmental destruction. Tesla might not be around in two years, they are on their way out of business. Can't turn a profit, can't make production, extremely inefficient production is 8 times more expensive then car production in the 1980's. Yuck. Tesla might sell batteries to people who know to make cars, but right now Tesla doesn't know how to make cars.

I agree but people love buying their stock at a really high price and their cars. Plus it is about time to refresh the model S. Been around sine 2012.

But Elon Musk knows how to sucker people. He's a bigger con than Bernie Madoff, and a lot smarter. He does it legally, and he gets people to worship him in the process. That's a pretty good insurance plan against prison time.

Even diesel locomotives are essentially electrical vehicles...

Yep, with a mogen as a transmission. In many cases that's more efficient than a hydrostat (but more expensive.)

Since there is no such thing as a free energy, you should understand that a wind turbine on a moving vehicle could not generate more power than it takes to move it down the road. Now, as to "self-driving trucks," stop and think. That truck is going to need a driver when it gets to where it's going. It will need a driver in case of any emergencies or unusual traffic patterns. This is not going to be happening any time soon. (Hybrid trucks are already here. They've been on the roads over 5 years.)

Since there is no such thing as a free energy...

Sure there is...especially since energy cannot be created or destroyed...it's the harnessing/storing/refining etc. part that comes at a cost...

You miss the point. Elon is a technology disrupter on a mission to eliminate automotive vehicles as a primary contributor to air pollution. He's not trying to compete with GM or other major OEMs by producing 5-10 million vehicles annually. His goal is to produce enough affordable ZEVs, 500,000 or so per year, to keep the pressure on the big OEMs to play catchup with Tesla's products by developing ZEVs of their own. That's why nearly 10 years ago he made all of Tesla's ZEV patents public. And so far he's been able to attract a huge number of both small and large idealistic investors who share his beliefs about the future of automotive technology and who put their money on Tesla.
