  29. Sure, if it's real. Funny that the truck that drove the 500 miles wasn't carrying those things. They just showed those things for the few clips. For all we know, they loaded up with a tiny battery pack capable of only about 10 miles, just to take those shots. Then, they load the full battery pack for the other clip of them going 500 miles with a light load. Or, maybe those concrete barriers have been hollowed out, or maybe they're Styrofoam painted to look like concrete. The point is, we already know that Musk uses deceptive practices to accomplish his marketing goals. He's done it time and time again. Why he wasn't imprisoned for the Solar City scam, I'll never understand. And, the same goes for the rest of his nonsense, like Boca Chica, and the fake Hyperloop "vacuum" tunnel (that wasn't a vacuum), and the fake robot doing tasks with jump-cuts and CGI editing. The man cannot be trusted. And, as long as he refuses to reveal the weight of the truck (and the price, for that matter), there's absolutely no reason to trust anything he shows in videos. The proof is in the pudding. Musk doesn't produce pudding. He produces videos about pudding. And, still today, we don't know the weight of the truck, and even Pepsi won't reveal it (undoubtedly they've been contractually obligated to keep it a secret). But, it's awwwwfffulllly telling that they said they're not going to haul any Pepsi for 500 miles. Instead, they're only hauling potato chips for 500 miles. And, if the numbers weren't tragic, why would they be a secret? Why? What possible reason would they have to keep the numbers a secret, unless those numbers were horrible?

  40. Yup. Everyone knows what's needed to stop burning fossil fuels. But, the fundamental problem is that to find a new fuel to replace carbon emitting fuels, you're basically talking about needing to chemically manufacture them (such as hydrogen). You need to pay in money and energy to split water into oxygen and hydrogen ,and this takes 8x more energy than you can ever get back out of the hydrogen. Or, for a more complicated but safe fuel, you have to chemically manufacture it (again, meaning you have to spend a lot of energy and money to do it). At the moment, the best alternative we have is electric/battery vehicles. But, you're right, it's far too expensive, there's a lack of natural resources, and you just can't use that sort of thing for all applications. Not only is it a problem for large long-haul trucks (i.e. this video), but, it's a major problem for aviation also. They just can't get the batteries light enough to make them viable for aircraft use. A car carrying a few people, where you don't care how much it weighs, ok, you can pull it off. It's terribly expensive, but, it works. But, it's very difficult to scale that up, because of the weight constraints, and the supply of natural resources is restrained (as you pointed out). So, yes, a radically different battery (which we don't even have any ideas about how to make, or even what to make it from), or some sort of clean burning fuel, would be wonderful. But, they just don't exist yet, and I dare not guess at the odds of actually making them exist.
