Not really at all. That is another lie as you seem to conveniently

freight transportation.

We simply do not have good enough batteries yet. Period. One can
place the biggest electric motors around into a tractor and if it
cannot do the load or move the distance, it is worthless for the task.
To integrate a battery which can means you are now moving the weight of
the battery pack around as well.

You do know that Tesla already has built electric semis and is presently road testing them, right?

I don't know this for a fact, but I expect one of the limitations currently is the charging infrastructure. While it is very good for taking autos on trips, they use eight charging stalls to charge a semi. They will need to build new semi charging stations. Unlike autos which will be charged mainly at home, semis will mainly be charged on the road. They will likely only sell semis for specific routes initially and build the charging network to suit, expanding the routes and sales together. Or they might initially sell to short haul markets where charging can be done overnight at the owner's facility.

That gives me a thought. It is rather pointless to have solar cells on a car because the relatively small surface area doesn't impact the battery drain much. But on a tractor trailer the surface is *much* larger. I wonder if this could be used to greatly increase the range with a lot fewer batteries.

https://en.wikipedia.org/wiki/World_Solar_Challenge

The solar powered cars do get along at decent speed.

A loaded tractor trailer is lot heavier.

Silly idea. Electrified railroads are standard everywhere where
the population density is higher than in the US.

electrified railroads move people. REAL locomotives move freight.

Rubbish. Really heavy duty locomotives used to be diesel-electric - electric motor are better adapted to providing the necessary torque at the wheels over the wide range of rotation rates needed.

The only economic question is whether taking the electicity generation out of the train save enough - in reduced load to be shifted - to pay for the overhead wiring along the whole lenght of the track.

Higher population densities - and thus more rail traffic along the track - makes electrification more attractive, because it is a a one-off cost, and you have to lug power generating unit along with every load you shift.

REAL locomotives are diesel electric. ALL our trains are
electric, but not on an overhead grid.

Your characterization of the 'idea' being silly, is pretty stupid,
because it is not silly, and it is not my idea. India, in fact, has
the first CNG train there is.

Does that make it clever?

So much for your population density analysis.

So much for yours. The metric is the number of people per unit area who will pay to use the train, or shift freight on it.

India may have 382 people per square kilometre - alomst twice that of Germany - but it's average per capita income is a whole lot lower.

Easier here to put a train on existing tracks that powers itself
than it is to erect overhead power feeds all over the place.

Of course it is, but you only have to put up the power feeds once, and they save money on every train trip. Lugging the diesel part of a diesel electric locomotive around costs money on every trip, and the overhead wires save that on every trip.

Not sure what you are talking about. The weight of the diesel motors is not an important factor in trains. In fact, they used to use "Bud" cars on a local line which had a motor in every car! Talk about weight inefficient. Clearly the railroad doesn't care.

Bullshit. It is about a MATCHED delivery JOB. Stopping ten more

But not by much. Your idea of what might be acceptable has been presumably mined from your rather-less-than creative imagination.

Nope. It MUST be able to perform trip runs in the same time

If the price is right, the end customer is likely to be more flexible.

You apparently do not get the requisite, because you keep coming
back with more labor intensive, more ridiculous means to move
between two points on a map.

Trucks are labour intensive. Putting the containers on properly automated railway system makes a lot more sense.

For a while all inland freight moved around on railways, but trucks got practical before containers were invented, and America missed that particular boat.

MAYBE they could do short haul city trips with those short
trailer... MAYBE.

Still not even viable yet for that.

In your ever-so-well-informed opinion.

But the prime mover only needs to tractor the load between

You are an idiot with that one. One will NOT be charging their
tractor trailer trucks overnight, AND as I stated, the difference is
unacceptable.

Whence "charging stations or battery swap stations".

Rick C keeps on telling us that he can recharge his Telsa in the time that it takes him to buy and drink a cup of coffee. That's not overnight.

You are misquoting me. I said have a meal, not have a coffee.

Today I am driving up to Frederick to have dinner. I think my usual meal stop may not be a meal stop. It will truly be a charging stop... unless I decide to have a light lunch at the Sheetz. I much prefer a Wawa.

Once the charging station in Frederick is ready I'll be able to charge much more effectively. It will still be twice per round trip, but one will be light to get me around town and the other will be larger to get me down and back.

As the market matures there will be a lot more convenient charging locations.

Again, like I said earlier. LEARN HOW TO READ.

So what? Most big cities are pretty close to that already. You can get a car into the city centre, but it always takes ages, and usually costs a bomb.

The people who keep on using them are mostly making the point that they can afford to waste time and money drivng around in a (generally expensive) car.

Overhead electrical lines pose huge problems, and not just making new

Why not develop some Pony Express style operation. At selected
stations leave the emptied tractor at the station for charging and
take a fresh fully charged tractor to move the trailer to the
destination.

Because unlike the wild west, we have laws about how much a person can drive before resting. Unless you want to pay two people to move your load, it has to stop periodically for the driver to rest. No real need for battery pack swaps.


For longer high volume routes, put the trailer on to a train or ship
and then use ordinary tractors at both ends of the route.

You are aware they already do that, right? The down side is trains are very slow. They often average only 30 miles per hour and individual loads can be slower sitting in a rail yard waiting for a different train to take it further. Expect a cross country trip to take two weeks.


You do know that Tesla already has built electric semis and is presently road testing them, right?

I don't know this for a fact, but I expect one of the limitations currently is the charging infrastructure. While it is very good for taking autos on trips, they use eight charging stalls to charge a semi. They will need to build new semi charging stations.

They will likely only sell semis for specific routes initially and build the charging network to suit, expanding the routes and sales together. Or they might initially sell to short haul markets where charging can be done overnight at the owner's facility.


Do you how much energy a semi-trailer will consume ?

A battery operated city bus can handle about 1 km/kWh, so it is
possible to quick charge the bus at the end(s) of the line, while the
driver takes a coffee/tobaco/toilet break. Alternatively, install a
charging station on each bus stop and each time the bus stops on the
bus stop for 5-15 seconds charge the bus.

That gives me a thought. It is rather pointless to have solar cells on a car because the relatively small surface area doesn't impact the battery drain much. But on a tractor trailer the surface is *much* larger. I wonder if this could be used to greatly increase the range with a lot fewer batteries.

What is the top surface area ? Perhaps 50 m² and assuming about 100
W/m² (with suboptimal solar angles) that makes 5 kW (7 hp) or in one
hour charged by 5 kWh, so a city bus would run 5 km once an hour and
much less for a semi-trailer.

Yeah, I found a page that shows a class-8 truck using 160 kW for level ground at 65 mph.

The fact that you can buy electricity from the grid much more cheaply than yu can get it by running a mobile diesel--power generator is probaby a bigger factor.

Suburban railways, just moving passengers, aren't all that weight conscious.. The trick there is to be able to put together long trains to move a lot passengers at once at peak hours, and serve the same route with shorter trains when the demand it less. One motor in every car makes it lot easier to adjust the number of cars in a particular train running at a particular time..

Dude, you might as well give that one up. My dad was a railroad dispatcher and a friend is a buyer of food goods which are nearly always trucked rather than deal with the problems of railroad freight. Long delivery times, unpredictable delivery times and the requirement for large loads. Then there is the need to coordinate truck hauling at each end.

Railroad freight is used in the US, but not nearly as much as trucks because it is a PITA mostly. Trucking is a bit more expensive, but a lot less hassle and in most cases the only real option because of scheduling issues. One week vs. two or more weeks is a big deal.

It seems Tesla uses railroads to deliver their cars in the US. The scheduling issues prevent Musk from ramping up deliveries at the end of the quarters, so he wanted to build his own trailers... lol
