Here's the best short video that I found
Diesel contains about 10 kWh/L, or 38 kWh/USgal. 6 to 10 mpg or 0.17 to 0.10 USgal/mile is then 6.3 to 3.8 kWh/mile (of chemical energy, not electricity)... and personally I think the 6 mpg end of the range seems more likely if actually loaded anywhere near 40 tons....
Trucks get 6 to 10 mpg and gross 80,000 lbs...
A hybrid certainly makes more sense today. Once they improve the energy density sufficiently, or come up with a viable and standardize battery replacement system for long-haul truckers, then it will no longer make sense to have the duplicate power systems. Wrightspeed is certainly interesting, but again I would question the use of the micro-turbine - after all, I don't believe they are claiming it is actually more efficient than some piston alternatives. Something else capable of generating exactly the maximum steady-state driving power, perhaps a free piston diesel, might be more efficient.I think Wrightspeed has the right idea. Whether you agree with Wrightspeed's hybrid approach or prefer straight battery-electric, long-haul trucks are not a rational place to put expense and effort, if the purpose is to reduce fossil fuel consumption. Stop-and-go operation of transit (buses - already available), service (think garbage), and local delivery vehicles is a more useful but less attractive market; Cummins targeted Class 7 urban hauling with their tractor, and Mercedes Fuso chose a medium-duty straight truck.
"teck" illiterate?The talking heads on CNN are laughing at Elon's flying car this morning , not even mentioning the semi or hipper car. They can't be that teck illiterate.
The Semi is no more "game changing" than the other electric heavy trucks which are available, and it introduces no new technology. That doesn't mean it won't be significant when (and if) it is actually produced, but it is no miracle. PR bull doesn't do anyone any favours.Brian, are you saying the tesla semi and the sports car are not game changing events .If so what is interesting .
That's sarcasm, right? It's legitimately hard to tell in some of these discussions. The Bugatti Chiron is a "supercar" - a title applied to any extreme high-performance car with a huge price tag - but it's neither a heavy truck nor a competitor to the Roadster, so it's not a rational comparison point. Tesla Motors couldn't build a single car like the Chiron if Elon's life depended on it; it is certainly state-of-the-art, as are many cars.The Bugatti is not a super car and has no state of the art engineering.
I find EVs interesting and I love engineering; these vehicle announcements are all about marketing and have nothing to do with engineering.It sounds like you just don't like ev's or engineering , you didn't talk about 20% less cost and the ability to do 500 miles , that's all that matters to trucking company's, except you did mention refueling but so did elon and has done it before(supercharger)
