Tesla to Unveil Electric Tractor Trailer

The VR headsets from the 80s were terrible. I mean, here is a $79,000 VR system released in 1991. Virtuality

The VR was simply so bad it turned people off the whole thing, which was fine because the technology wasn't there in the first place. I've heard a lot of conspiracy theories about electrical vehicles. I'm sure they existed, and I'm sure they worked, but I doubt they were good enough, and once it stopped being trendy, people went with what was more convenient/cheaper.

Why I quit Prime's TNT Program

I think Lil Stevie was being honest about himself. I was going to defend his decision to not spend time with a stinky trainer forever against the silly idea that it's giving up - instead of simply sidestepping a very unpleasant and worthless endeavor, all to possibly prove something to to some simple minded exploitative employers, but I see it's well beyond that now.

The fact he was going to quit from boredom was clear early on in his posts if he was being honest.

I was out chopping wood, and realized that people around here totally wouldn't interpret the things I said in here in the same way they were meant. When I said, "I don't see how it could be done." I meant with Albany Mike's criteria of comparable performance and price range, and with current technology. Further, I was thinking of an actual electric truck, and not a hybrid.

I'm sure whatever Tesla has cooked up is promising, and I'm sure it'll help pave the way to more pragmatic solutions. I have great respect for Elon Musk... I just wish he was better at talking. (Guy sounds like a rambling idiot.)

Well, the Nikola One truck uses hydrogen fuel cells. To run a generator to charge batteries/power a motor is much less efficient than just burning the fuel to power the truck in the first place. I'm guessing they make up for this fact with regenerative braking, if what you're saying is true.

Brett,

Where are you getting the details on Tesla's truck? I've not found them yet.

ChosenOne,

I was curious so I looked it up. Diesel has gravimetric energy density of 13,333 wh/kg whereas lithium ion batteries found in the tesla are in the range of 100-243wh/kg.

Which means it's ~54.87x heavier to store the same amount of energy on a truck in a battery. So 200 gallons of diesel weighs 1236.6lbs, and that amount of energy stored in batteries would weigh 67,852lbs best case. LOL

I haven't looked into it any, but I don't see how it could be done. The energy density in batteries is so much lower than that of gasoline, you wouldn't be able to haul as much cargo and stay in legal weight limits.

Elon Musk is an awesome guy, though. We hear so much about worthless exploitative CEOs like Steve Jobs, and not enough about people that are actually changing the world in big ways, and for the better.

Watch: The World's Smallest V12 Engine

I went into this getting ready to roll my eyes over some silly truck driver getting excited over something unimpressive, but that actually is impressive. That guy has amazing skills. I can't fathom how he did the camshaft to get the timing right. I wonder why he uses flat head screws? Also, I wonder how much HP it has.
