NaturallyAspirated Posted November 28, 2017 Share Posted November 28, 2017 Doing some math it seems a bit absurd. It has been quoted at less than 2kWh per mile, and with a range of 400 miles that's 800kWh, which would be worst case scenario. To be able to charge in 30 minutes would require 1.6MW. Dividing out 1,600,000/4,000 = 400w per home. Does anyone think they could run their home on 400 watts? Neal Quote Link to comment Share on other sites More sharing options...

That's a ridiculous amount of power.... for just one truck. Now imagine 20 of them lined up like they are fueling up at truck stops. That's enough to power up a small city. The amount of potential energy in a 2MW system is very dangerous. The arc flash hazard in a system capable of delivering that kind of power would easily kill you instantly in the event of a fault. The technical logistics of a safe, consumer operated charging system of that scale would be arduous. Never mind that electrical grid infrastructure would would never be able to those kinds of loads being added without major upgrades. Musk is the modern day PT Barnum.

teamgreen02 Posted November 28, 2017 Share Posted November 28, 2017 We would need power plants on every corner with massive transmission lines. It's just not practical on longhaul situations. Short haul and yard trucks could be possible. Autonomous trucks are a bigger deal with the driver shortages. Would be a huge cost reduction worldwide for freight.

Gold Member BOHICA Posted November 28, 2017 Gold Member Share Posted November 28, 2017 (edited) at 1.6 Mw you need about 4 large scale wind turbines operating at there average annual efficiency of 24% to just charge 1 tesla semi for 1/2 hour. There are 3.6 million or so class 8 trucks registered in the US.... So you would need 15 million or so 1.5 MW wind turbines at the current average annual turbine efficiency to power an electric truck fleet that is equal to the current diesel fleet if they decided to charge at the same time. Not to mention all the child labor in third world countries with lax mining emission and pollution regulations to harvest the necessary materials to make this happen.

Rod Posted November 28, 2017 Author Share Posted November 28, 2017 The problem also isn't really the absurd amount of electricity they use. The problem is storing it, and transferring it. Supposedly the batteries for the larger truck may weigh anywhere from 10-20 tonnes rendering them way to heavy to start with. Quote Link to comment Share on other sites More sharing options...

Gold Member BOHICA Posted November 28, 2017 Gold Member Share Posted November 28, 2017 (edited) Coal is here to stay globally. The surge in coal power plants is great for the US coal companies as exports are increasing. https://www.nytimes.com/2017/07/01/climate/china-energy-companies-coal-plants-climate-change.html Over all, 1,600 coal plants are planned or under construction in 62 countries, according to Urgewald’s tally, which uses data from the Global Coal Plant Tracker portal. The new plants would expand the world’s coal-fired power capacity by 43 percent. Edited November 28, 2017 by BOHICA Quote Link to comment Share on other sites More sharing options...

He might be a little more than a great marketer. He makes some awesome cars. He landed a rocket on a motherfucking boat. When was the last time a new car company started? Solar roofing. Most of it is out of the realm of basic consumers but there will be a niche. Maybe these trucks will only be good for day runs. We have a lot of trucks that leave our area and spend most of the day in city traffic. Reduced pollution from the electric trucks that won't use any fuel while stopped in traffic, at lights and waiting their turn at the terminal. The green comparison could go a few ways. Either compare how much diesel a normal truck would use going 500 miles vs how much diesel, oil or natural gas it would take a generating station to create that electricity. That is going to be the least favourable to Tesla. But considering what else he is into, you should go into life cycle costs of the solar panels needed to produce the electricity for this the truck. It would be a huge calculation. Lifetime of this truck and extraction of all of the resources needed to build it, maintain it and build and maintain the solar panels that would be required to fuel this truck. Plus the environmental impacts of all of those items. Then you need to compare the same materials for building, maintaining a diesel truck for the same mileage. Plus extracting the diesel, oil, refining it, transporting it and maintaining the infrastructure as a percentage the truck will use. Then the overall pollution from both methods. Keep in mind solar is going to keep becoming more efficient. Right now if you put 100 charging stations at a mall, our grid wouldn't have the capacity. But if most buildings around that mall end up with solar panels the grid would be irrelevant. Musk is about the future. You shouldn't blame him for the pollution caused by coal fired generating plants. Quote Link to comment Share on other sites More sharing options...
