| All of this is basically wrong. > Certainly not without a transmission. If you have 6 wheels and you can put an engine on each one there is zero reason what so ever to suggest you can't get enough torque. And if you look at the Tesla Semi you will see that it leaves every other truck in the dust while fully loaded. > Also there's the total cost of the vehicle to consider. All indications of electric drive show far better total lifecycle cost then any ICE has shown. I don't know about fuel cells but I don't think hydorgen in any form will have much of a market. > You've seen teslas burn so you know that side too. Any state will tell you that they burn far less often then any other car. And even when they do it almost always not an instant fire but a slowly developing thing. And we are still at the infancy of battery tech, there are already much more advanced suppression systems being tested both for the pack and the cell. On pack level you can look at Tesla structural packs (that will be in the Semi too) and on the cell level there are Soteria. In 5-10 years getting an EV to burn will be borderline impossible. > These technologies would make a lot more sense if we could source cheap electricity from renewable sources, and we don't. All over the world they already do. Most EV load at night and can profit from cheap base line energy that is often nuclear or access wind. And even if its not zero-carbon power now, if the truck/car has a lifetime of 15 years it will be increasingly more carbon efficient over time. And additionally even with coal power its better to drive EV. > It's consumers and pop-sci that's driving this change, and that's not necessarily a good thing. Not its the fact that electric cars and trucks are simply better and more practical in many ways. The lifetime cost are considerably better. The cost curve for solar and wind is still collapsing and its idiotic to wait to switch to substantial transport only when you reach some % of the energy source you want. Because from that point on it takes 30+ years to make the transition. You have to do both at the same time, anything else makes no sense what so ever. |
