OK there are roughly 50,000 miles of interstate. I'm sure you'd want to add in all those miles of state thruways and such so lets call the total 70,000 miles. These are all multi-lane so let make a guess and call them 6 lanes, 3 each way, on average. Those will be more expensive to electrify so lets call that $1,000,000 a mile which works out to $70,000,000,000. Who is going to pay for that? I vote electric car owners should foot the bill. Plus the O&M costs.

The beauty of is that with the car being constantly charged while driving, then the on board battery can be a lot smaller, as it would only be needed in residential areas.agesilaus wrote:4x4ord wrote:
I think it makes sense to have the power for electric vehicles embedded in the roadways to keep the batteries charged as the vehicles drive along the road... kind of like trolley busses.
LOL how many millions of miles of roadway are there in the US? Aha! There are about 4,071,000 miles of road, changing all the time of course. And figuring a conservative $100,000 a mile to electrify that would be $4,000,000,000, that 4 Trillion bucks plus operating and maintenance costs. And that does not include all the dirt an gravel roads that we like so much out west.
Not to mention the fact that wireless charging is very inefficient and wastes a lot of energy. There is also the factor of voltage drop over long distances.

:h who called out Tesla? Are you suggesting that Jason Fenske's analysis is flawed because it references Tesla?
Not flawed at all. Just that it is an EV problem not a Tesla problem.
Same as calling out FORD because the DEF hurts performance and economy when ALL have the same issues.

How many folks tow at 75 miles per hour? 55 would make more sense.

The OTHER issue with the BIG RIG will be the NEW "ELD" Electronic Logging Device... The drivers have to factor inn the fact that they are "On Duty-Not driving" at each fill up.. They only have a certain amount of hours to work with.. Charging could eat into that pretty fast..
"This window is usually thought of as a “daily” limit even though it is not based on a 24-hour period. You are allowed a period of 14 consecutive hours in which to drive up to 11 hours after being off duty for 10 or more consecutive hours. The 14-consecutive-hour driving window begins when you start any kind of work."

I think you just answered a question that has been a minor puzzlement. In the last year or so why have truck parking spots become so hard to find. In rest areas and such. This device must be preventing their workarounds for skipping rest breaks.

Break it down some. A trailer truck with 240 gal fuel tanks can travel 1200 miles before stopping to fuel. Hmm that is what 3 times farther than the pictured truck can go. and can be refueled in 15 minutes. This is very important. most time when you load, and go. You have a time limit to deliver your load. get there late. You lose money. You really don't have time to stop and charge batteries three times compared to not stopping with diesel in the same 1200 miles, and the farther you go the more you have to stop. This is a time killing option.
Normal tractors weight in the 25000 to 30000lb range. leaving a payload of 50,000lbs, and for them weight is money.
How much does the electric truck weigh? Well we aren't told. But I would tend to believe it weighs considerably more than a normal tractor. just for fun, say weighs 40K. You have just cut your payload 10000 to 15000lbs. You just lose money. And you got there late.

A lot comes down to the type of towing you do. Granted, most people on this forum are expected to hitch up a camper and go cross country so range is very important. On the other hand, I tow a trailer most every day with my business but rarely travel more than 120 miles in a day and there are probably quite a few contractors that meet that description. The Tesla truck would probably work out very well for me. There are quite a few people that just want to run down to the building supply store and pick up some lumber. The Model Y towing a small trailer would work for that. The advance orders for the Semi are mostly from companies with defined runs less than 500 miles between facilities that they own and can put charging stations at. I think that we will see EV's towing trailers first in niche markets then expanding. It would also be nice for me to be able to leave home every day fully charged and not have to worry with getting my trailer through gas stations.
Meanwhile, Tesla keeps improving battery life and charging rates. This will make the EV as a tow vehicle more and more practical as time goes by.
