Hi Bumpy,

That is a different vehicle altogether, called Star Ship.

It has had two failures, one before landing, and one shortly after landing.

Not sure SpaceX is calling those failures. Common and normal to testing rockets.

as Bill said once, "depends on what your definition of "is" is".

Exactly what "current semis" are you referring to? The ones that have yet to be seen in actual use?

Yeah, yeah, yada, yada...

I'm actually referring to horse drawn wagons pre-Ford Model T..:R

Dude, try to keep up. These are the same people who are better than NASA that promised and delivered a re-usable rocket that they were told is not doable.

They not only did that but give them one that can land on a barge (when NASA scientists themselves are saying that landing a space shuttle back to earth on that extra long runnway is like threading a needle from 10 floors up a scraper on gale-level winds.

Geez!:S

Ah, I guess I missed the part where the semi is in production. That's what you're saying isn't it? That the semi is now in production? Or am I correct about it not being real yet? Try to keep up with the current post before introducing extraneous subjects.

I really don't give a rat's patoot about reuseable rocket boosters. Near as I can tell, it doesn't have much to do with the semi, does it?

remind me not to book a flight on that one quite yet.

And as of less than 24 hours ago:

"The rocket’s first stage landed on a droneship in the Atlantic Ocean eight and a half minutes after liftoff. That booster was on its ninth flight, a record for the Falcon 9. "

which was the one that burst into flames shortly after landing?

This isn't a power the house question - "but"

I just did some work with a 2006 Dodge diesel pickup and goose neck flatbed. Due to the off road and back road nature of the work "miles" are not the same as highway.

A machine was moved to the location and back after the work. 2 loads.
10 loads of 8 tons +/- each of bales were moved in 2 mornings. GCW would be about 30,500lbs each trip. Don't panic this truck has done this kind of work for years.

In about 12 hours of hauling totalling 280 miles the truck used 60 USgals of diesel.

Let's say a BE "1 ton" 4x4 existed to compare, one with 300 ish hp like the Dodge.

Could it do this work in two 6 hour days, with an overnight charge - 12 trips at 30,500lbs.

I'm not sure how to convert 5 gals per hour of diesel fuel used into kwhr of BEV range...

It's really hard to say for sure, because real world data on existing commercial EVs is hard to find. Navistary has a prototype commercial medium duty electric truck with a 312 KWH battery, claiming a range of up to 250 miles. 30K GCW should be well within the capacity of this platform, although the article does not say what the truck's weight capacity is. I would think that a truck with this drivetrain and battery could do this job, especially in a two day period. The Cybertruck Trimotor has a 200 kwh battery, and while 30K GCW is well over its rated capacity, it would likely easily move that kind of load unless protective software prevents it. With the 200 kwh battery, though, it might not have the capacity to do that job, even over a two day period. The fact that this job caused a Cummins powered Dodge to only get 4 mpg says that a lot of work was getting done. An electric truck could gain some efficiency if there is a lot of stop and go driving as compared to highway driving. IMO commercial EVs will excel at short haul and delivery applications but will struggle to be as productive as diesel trucks in over the road applications, at least until battery technology advances. If a semi with a 1 mwh battery is ever built with no weight penalty compared to a diesel semi it will be a close call. I think some day it will.

This is very insightful and provides a rational and reasoned challenge to Semis (where innnovatioons in range, battery technology and re-charging turn-around will benefit Cybertruck.)

Indeed, the consensus out there agree with you that their current semis as is will be most competitive in short hauls (I think that's where most of the pre-order uses are).

Nothing official out there but some punditry from techies that Tesla's immediate goal is a new battery range that would at least equal current diesel semis truck stop and refueling and rest cycle. Other idea is customized and dedicated trailer with the bed of battery array and add-on motors.

I really don't know. I'm also speculating and not vested on the semi -- except for possibility of some RV manufacturer converting one or it's technology innnnovattions cascading on my pre-ordered Cybertruck.

The Cybertruck providing electricity to may rv (or may home). That's a bonus, and if it can't, this not a deal breaker..:B
