500 miles means more stops (if the stops have chargers), longer stops, longer trip times for cargo and less earnings for drivers who get paid by the mile - no matter how long those miles take.

It also appears that the unit doesn't work with industry standard trailers which is a death knell.

This is typical Musk vapourware

This doesn’t really apply to “solo” over the road truckers as they are regulated by the Federal government. Driving double team is a different story. A driver can only drive so many miles per day-per week, etc.

The trucks can be charged while they are taking their federally mandated breaks. These rules are enforced by truck stops and drivers log books.

Just curious, has Musk stated a position on where he thinks electricity ought to come from?

He owns large portions of solar stuff. I would guess that's just the area where he sees the most room for innovation to breed profit. Most people into electrical stuff see a combination of solar, wind and nuclear (with hydro where possible) being the answer.

A buddy of mine at work told me a while ago that it takes more energy to make any given photo voltaic cell than you'll ever get from it in it's entire lifetime.

I don't know if that's true or not, but if it is, then PV cells are merely a means of shifting the environmental damage / cost of the energy produced from the end-user (say, US or Europe) to the location where they're made (say, China).

That's somewhat true regardless of the ratio of input to output, but for the earth's environment as a whole that would truly be galling.

Does anyone know if the "you'll never get out more than you put in" statement is true?

In much of the US, it's under two years for the embodied energy of a PV system - it depends on available sunlight and the efficiency of the system.

call me cynical.....but the truck and roadster announcement all curiously coincide with being reportedly close to running outta cash.

gotta keep the equity markets enthused. or the gov't subsidies rolling in.

somewhat quietly, they've done some interesting structured financing on the solar side of the fence.

all that aside, the tech is amazing.

This. When the electric semi announcement came out, with JB Hunt and Walmart placing pre-orders, (which means jack diddly squat as no money will likely exchange hands until a hard deliver date is met and there'll be clauses/penalties if the semis being ready do not meet deadlines, which will be very likely), the share price jumped 4%, but reality must have set in as the share price closed up only .08%. Lawsuits on the Model3 delays don't help.

If and it's a gigantic IF the tech can be a reality, yes, it's amazing. As a professional truck driver, the thought of no diesel fumes is quite enticing. This as a reality in a realistic time frame, my bet is nope.

The statement is categorically false. Studies have shown that, depending on the technology of the actual panel, it takes between 1 and 4 years to result in a net zero of energy to manufacture vs. energy produced. Given that the panels will continue to generate for another 20 to 25 years, there is no issue.

of course wasn't bob lutz at the helm of gm when it needed a bailout form the federal government?

Full disclosure, I drive a truck for a living, for the last 25 yrs.

Nice fantasy, but 500 miles of battery life with a full load at GVW of 80K lbs? And not much room for much of a load on that truck, with the 22 ton battery needed. Over promising is Musk's modus operandi. If the debacle of 260 of the promised 1500 Model 3's is any indication, the electric semi is quite far off.

Ignoring the problems of production (and irate customers), how many people can handle a car that does 0-60 in 2 seconds? I'm pretty sure I can't, and I'm no stranger to driving fast cars.

This^^^^^

Unless Tesla will rely on "computer assisted" driving to guide that missile, many people who have the financial resources but not the driving skill will learn just how fast 60-0 is possible.

Some commentary on the numbers put forward by Musk,

Musk, to be me, is just a 21st century snake oil salesman.

This is not going to end well.

The only thing i did not like about the truck was the "solo driving mode", you cant rely in a computer to drive that thing, the radar fails and you kill like 100 people with that darn truck.
