EDIT: to make zero effective load on a multiple motor without a clutch they must be applying SOME power to the motor and turning that load condition into at minimum a null load The load you feel there is primarily the inertia, not friction or any magnetic resistance. Thus, if you do start it spinning, it keeps spinning, and you must work to slow it back down. Of course, since it's a real-world device, there is some friction and it will eventually slow down. If you want to slow it down faster, you can short the electrical wires and it will slow down much faster. 1 Quote Share this post Link to post Share on other sites
Tomasz + 1,608 January 30, 2021 (edited) Personally, I drive a Dacia Duster, a SUV for the poor. If I had more money, I would buy Lada Niva because it has great driving conditions and I like to tinker, so I would not be discouraged by the constant problems with the car. A few years ago, I read that the Ford F150 is the best-selling car in the United States, probably in 2015 after the collapse of oil prices. Generally, I am a fan of SUVs and I would buy a better car but for now the Dacia Duster has to be enough. However, I cannot imagine an electric SUV driving across all forest or mountain areas for a few days, if only because of the limited range of this type of vehicle and often very difficult terrain conditions. So I would stay with the ICE SUV. As I said Dacia Duster below- cheap economic SUV made in collaboration with Renault-Nissan. You probably never heard about it in USA but its quite popular in middle-income countries in Europe. Edited January 30, 2021 by Tomasz 3 Quote Share this post Link to post Share on other sites

EV's are just far to expensive to produce and the public at large really do not want them. Govt incentives need to be stopped, far to much wealth is going down a dark hole. There will come a time when that day happens, as of now we are far from it. The EU will be experiencing enormous blow back in the coming yrs, already they are experiencingas much.

The global market is about 92 million vehicles/yr. Tesla sold 500,000 last year, so you can see that Tesla has higher US market penetration than global penetration. Tesla (Elon) thinks they will maintain a 50% annual growth rate for the foreseeable future. That's more than doubling every two years (a 41% growth rate has a doubling time of two years). That's 5 doublings in ten years or 16 million vehicles/yr in 2030. The "big 3" are not the biggest car makers. Toyota and VW are the biggest at about 10 million/yr each. The traditional auto maker will "let this go on" until they completely re-invent themselves or they die. Only VW is really trying to re-invent. The rest of the industry is too firmly wedded to their century-old successful business model. Even VW is getting pushback from their dealers. 1 Quote Share this post Link to post Share on other sites

Doubling every two years results in 16 million vehicles/yr in 2030. Doubling every year gets you 512 million vehicles/yr in 2030. But the entire world marker is only 92 million/yr, and the number of vehicles on the road is 1.4 billion. It's possible that Tesla will double in 2021, but the rate must drop eventually. At one point Elon mentioned 20 million/yr by 2030. Starting from .5 million/yr in 2020, that would require a factor of 40, which is a CAGR of about 41.46%. 1 Quote Share this post Link to post Share on other sites

They may double in 2021. They might even double again in 2022. There is no way they can continue to double every year for ten years because there is no market for 512 million vehicles/yr in 2030. Let's be wildly optimistic and assume Elon was being conservative(?!) at 20 million/yr in 2030. Let's assume 30 million Teslas/yr in 2030. That's a factor of 60 increase from 2020, or a CAGR of about 51%. Assume doubling for 2021 and 2022 instead, and you still need a factor of 15 from 2022 to 2030, or a CAGR of about 41% for those eight years. All of this is insane. Let's call a Giga Berlin or a Giga Shanghi or a Giga Texas a "Giga". To reach the 20 million/yr (i.e., doubling every 2 years) Tesla would need to have an equivalent of 10 Gigas each producing 2 million/yr. This implies that they bring their 3 Gigas up to 2 million/yr each and bring an additional 7 Gigas online and all the way up to speed by the end of 2029. That would be one Giga per year starting in 2023 This looks impossible to me. Of course, almost everything about Tesla looks impossible to me. In the mean time, Elon does not think the other automakers will go away. He expects that Tesla will have less than 50% of the EV market., especially at the low end in China and India. 1 Quote Share this post Link to post Share on other sites

(NOTE: Numbers here are not real-world predictions. They are used to illustrate the ludicrous consequences of sustained 100%/yr growth.) India and China (and to a lesser extent the rest of the rapidly-expanding economies) may buy a lot of new cars in the next ten years. The world's entire stock of vehicles on the road is currently 1.4 billion and the world's current production rate is 92 million vehicles per year. If Tesla were to double production every year for 10 years, they would make 512 million cars in 2030, for a cumulative 10-year production of 1 billion cars. These factories would be producng more than 5 times the current vehicle output of all the world's vehicle factories. This is patent nonsense. The highly-aggressive theoretical path I described (10 Gigafactories at 2 million vehicles/yr per factory) would achieve Elon's stated goal of 20 million/yr by 2030. To achieve 512 million/yr, you need 256 Giga factories, and if you stop your expansion at that point you will continue to produce 512 million each year. World population will probably stabilize at about 9 billion, and the life of a Tesla will almost certainly exceed 10 years, Thus, those factories could produce one Tesla for every two humans on the planet, forever. 1 Quote Share this post Link to post Share on other sites

Sebastian Meana + 278 February 6, 2021 i'm kinda tired of always people selling that EV cars will dominate and all of that and how the ICE is obsolete, and it doesn't really matter because cars are obsolete by itself, they are giant 1.5-2 tons pieces of machinery maded to carry a 100kg monkey using sticky rubber tyres over sticky asphalt, they will never be a efficient mode of transport doesn't mather if its powered with hydrogen, or gasoline, or diesel, or electricity, or hopes and dreams of a better world.And buying a car is one of the quickest way of wasting money, buy a car, it losses at least half its value in the first two yearsAnyone remembers quartz watches? they maded mechanical watches obsolete? yes, it does matter nowaydays? no, because watches are obsolete and are just tiny stuff that makes you look cool, even the most expensive tourbillon is less efficient and way less precise than a 20 year old quartz seiko ,but so what? people buys watches to look nice equally when EVs become the standard automobile people is going to keep buying Combustion cars because they have certain charm in them, Having a twin Turbo 2000hp V8 or 1000hp Cummins and making 140 decibels of noise,has no purspose apart from being an asshole and flexing and jerk o** in front of everyone to assert your dominance over lesser beings. And that's something you can't do with an EV in the same scale as with a combustion car 1 Quote Share this post Link to post Share on other sites

Boat + 1,323 RG February 6, 2021 (edited) Nice car, as a kid I loved the 1970 Nova. Back to the big argument. The SUV and other fan favorites will happen down the road. I will not suggest when. 😅 I do have faith in engineering and tech over a couple of decades. Batteries by then will probably handle much heavier loads. Charging stations will handle charging these bigger loads in much less time and they will be everywhere. Aerodynamics won’t matter as much. Solar with power walls will make it much cheaper even for electricity hogs. Our biggest problem will be death from the family car going from 0-150 in seconds. I predict an amusement park offering a rolling car launch at 150 mph where external bags will let you roll for miles.
