Tesla will reveal a semi truck in September

Actually green energy growth has outstripped fossil fuel growth over the last few years. Also, pollution never stay in one spot. It always spreads worldwide.
True enough. Batteries are going to have to improve a great deal before they can work well in all climates. However, there is huge research going into improved batteries. Sooner or later someone is going to get it right, especially as electric car companies like Tesla want their vehicles to replace all internal combustion engines.
Tesla Semi, an electric big rig truck with 500-mile range, rolls into reality
"Even with 80,000 pounds it'll get to 60 mph in 20 seconds," Musk said, hopping out of a truck. "What about up a hill?"
More significantly for trucking companies, Musk said that a standard diesel truck would be 20% more expensive to operate than a Tesla truck: $1.26 per mile compared to $1.51 per mile.
Musk said that if Tesla Semis were to drive in a convoy, in which trucks can draft off each other while letting computers and sensors keep them just feet apart at highway speeds, it could compete on cost with trains. "This beats rail," said Musk, throwing up an 85 cents per mile cost.
But Musk emphasized its performance. Tesla Trucks can hit 65 mph vs. 45 mph up a 5% grade compared to a standard truck, he said.
Then the biggest applause and hoots accompanied this stat: a 500-mile range, at maximum weight at highway speeds.
Investors were equally enthused. Shares (TSLA) rose 2% after trucking company J.B. Hunt Transport Services said Friday it had already placed an order for "multiple" Tesla Semis.
Musk hinted at a supercharger-less trip — no recharges needed.
"You can go 250 miles, deliver your load and come back," he said. That said, charging to 80% would take only 30 minutes, "or about the time of the average driver break" on a new solar-powered Megacharger network.

When will they come out with a line of farm implements where the seed-drill uses it's own tires as the propulsion system and the electric tractor doesn't have to do all the work? Remote control so it could find their own way around the field would be an area they could explore as trucks won't be driving themselves anytime soon.
It should be possible to make the trailers have motors on each axle that helps on slippery roads as well as recharging the batteries when going down inclines
If the trailers were set up like a bob-sled you could have 5 trailers hooked together and the last trailers would be in the same tracks as the tractor set town. That might work on ice-roads and interstates if they were always tabletop smooth. Crossing the Rockies will end at the first big hill and it doesn't matter if it is going uphill or down other than one ends at the runaway lane. Powered trailers would be a different story as they would be in total control no matter which way the grade was going. Moving them around the depot would also be a lot easier as you would only need a remote

Based on Tesla's inability to meet any production targets or financial targets, I would take this with a very large grain of salt.

Tesla releases the price of their semis - $150K usd for the 300 mile mode; and $180 K usd for the 500 mile model.
Way cheaper than I would have guessed. The fuel savings will pay for that truck in 3 years.

Gonna be real fun seeing how well those electrics work out when traffic is stalled for hours in the middle of winter because of a wreck, and it's still 200 miles to the next charging station.
Other that heating the cab a e vehicle would not be using any power. Rig idling their engines are in more danger of not making it to the next fuel depot.
Here is a question for the collective, NG has an octane rating of 120 making it the equal of AV-Gas as far as how much compression can be built into the engine. The 3600psi is a big hurdle and the fill time at a station would be 'slow'. Since 3600 is the pressure you get welding supplies in why could you not change bottles at a service station rather than filling up a tank that stays with the vehicle? 5 minutes at most
3600 is also the pressure the air is in scuba tanks so there are cylinders available and the compressor is expensive but it does exist and could be adapted to refilling bottles at home
Using NG in any engine that is now burning gasoline. To make it work at it's best it should have a compression ration of about 12/1. A turbo might be a better option that using just pistons to get that compression ratio.
It creates a lot less CO2 than gas so oil cutbacks could take place without gas becoming more expensive because there is less of it to go around. A conversion kit could be on the shelves by this X-mas if it became an emergency. Setting up the changes to factory built engines would be very simple also so nothing in production today would become obsolete anytime soon.
On a big rig a small gas genset could be carried along, put it beside the blanket and tire-chains that every vehicle should have.

Insulated battery boxes and a battery blanket would not draw much power and it would all the batteries to be able of delivering full power as soon as needed.

in fact at minus 15 or 20 when all those trucks run all day and all night up north the eTruck will be even more economical.
The batteries wouldn't be able to endure the harsh temperatures but even if they could, up north in places like Yellowknife, they're burning diesel to generate power for the city.
So what are you saving when you plug in?
