Teslas are well made, but not cheap to maintain. If the maintance costs (outside of the battery) are lower, but the inital cost is 2-3x more like is typical for cars, and the cost per mile driven is higher for fuel/battery then few people will adopt them.
I wasn't arguing that the idea itself sucked because of the range, there are plenty of uses for a truck with a 200-300 mile range. Just that the total cost is likely to be higher, both initial and per distance, which is going to cause very poor adoption rates. Main point here is battery tech still isn't quite on par with fossil fuel costs. We will see much better gains once the costs get comparable to diesels in the same way we see adoption of solar now that prices have come down.
Most big rig trucks can do 1000 miles (1600km) these electrics do 200-300. So already you are off by 3-5x. It's hard to say but I'm being quite generous on the price there isn't any data available. Here in America diesel is around 2.50 USD and they get 6.5mpg so it's about 32 thousand gallons and at 6.5mpg around 208 thousand miles, or 208 trips or around 1000 electric charges. Batteries don't last much over 600 full discharges before suffering pretty badly. Therefore it looks on the surface like the electricity plus battery is more expensive. It's not an economic win because even today tesla still isn't making profits, they are trying to get in the market early at the expense of losing large sums of money. It's a strategy that could work, and may drive prices down but sadly I haven't seen much of a drop despite Teslas efforts.
These trucks (well the diesel counterparts there are no details available I've found) can haul 80k lbs so a larger lithium battery isn't an issue because it's heavy. The main problem is it's still too damn expensive. Hopefully this will come down soon. Charging will be dirt cheap but a new battery will likely cost 50-80k USD before subsidy and won't last long if the vehicle is used commercially, much less than a car. It will be interesting to see what the true cost of ownership is after a decade of real world use.
When the car can drive in snow, heavy rain, fog, or around road construction let me know. As it is you can't even compare autonomous cars to people it's like gangsters to space stations as the only miles on self driving cars are sunny freeway miles and carefully planned city routes. No study I've seen compared them in the same situations.
Value is what people believe it to be. The US dollar is just as imaginary as bitcoin, the difference is there is an infrastructure in place to process it, whereas bitcoin is non-central. There are plenty of places you can exchange bitcoin, like gold, but issues like the one in the article do happen mostly because it's still in its infancy. Playing a mmorpg someone went off on how it's insane that in game gold has real value when it's imaginary, I pointed out that the in game economy of world of Warcraft alone exceeds that of Venezuela
IIRC every parallel element in a Li pack should be monitored and individually controlled, correct?
so I can have 100 cells in 10 strings of 10 and would need 10 controllers* to monitor said pack.
Then the parallel pack itself can be treated somewhat simply as a larger battery equivalent (e.g. if each of the hypothetical strings is 1Ah then I can treat the pack as a single 10Ah battery). The danger comes into play when cells are in parallel without protection, as then the stronger cell can actually damage the weaker cell in boundary conditions, leading to over depletion and over charging situations.
*in this case controller is specifically:
LV cutoff to prevent over depletion of string
Charge current limiting
HV cutoff
possibly max current drain too.
Close but no. As another poster pointed out a single failure in that parallel pack, if shorted causes a cascade like failure of every cell in parallel discharging at unsafe levels and likely results in a fire. If a cell goes high resistance or open the others have to work harder (supply more current per cell) to keep the same load and can be thermally stressed and fail by temperature overload - you need balanced cells with internal resistance and capacity to be nearly equal as imbalance likely from used random cells means one or two may be heavily overworked and others no so much. A single thermometer won't help. Plus your pack will have greatly reduced capacity from a single cell, because your pack will shut down when that parallel pack cuts off at LV (or thermal limits) prematurely. In well engineered packs it gets really fancy with much more than just low and high/voltage, charge/discharge current and low/high thermal limits.
Yes you could but it's like giving a 4yr old the controls to a 20 ton front end loader in your backyard. I'd rather a trained professional operate something capable of demolishing my home in minutes but to each their own.
We are looking at different photos, not sure which you even mean. I see dozens of batteries hard wired with heavy copper strips and short heavy copper wire in parallel, ones with lower internal resistance will be used disproportionately, there is no thermal monitoring or any way to remove one that Develops a short internally. FFS I have personally seen a fire almost burn down a building from loose lithium cells thrown stupidly in a box exactly as shown. Yes if one person does this crazy shit nothing bad may happen but as that number climbs past 10 the odds of at least one disaster approach 100% quickly.
The problem with using laptop batteries is not the batteries, the tesla uses them. The problem is the smart battery circuitry needed to monitor currents and voltages, balance cells, thermally monitor strings (or ideally individual cells), gas gauge, and safely disconnect problem cells from the system. The major advancement in the tesla is the amazing cooling/heating system and the ability to rewire itself to stop using problem cells. Simply wiring up a bank of unmonitored cells is a disaster waiting to happen. The vast majority of home hobbiests lack the knowledge and wherewithal to implement proper battery safety. The packs in the stock photos, if lithium cells, are a disaster in the making. Disclaimer: have designed smart battery circuits for lithium batteries used in actual products.
If you aren't in management then you start to get dumped on around 35. Just look at who is hired after 40 with a good resume and lots of experience vs a ok resume and little experience at 25. Perhaps if management, in general, didn't crap all over thier employees this wouldn't be nearly as pronounced.
Is that roughly 2 million millionths of a second? Because camera and laser scanner tech can easily take longer than a millisecond, and then you need processing time. There is no meaningful information in the article. I'm assuming it's some kind of beam scan as opposed to stereo camera vision. I find the idea of a constant scan of my face to be reprehensible to the point I use a tiny piece of electrical tape on my current phone as a manual camera cover.
If I even get one I'll disable the sensor for unlocking (for however much good that does me) but am very much intrigued by the 3-D scanning ability of the sensor. Maybe in a few years we can stitch together a moasic of these scans, and fuse them optimally, to make a truly portable and free moving 3-D scanner. That would be far more interesting to me than any bull crap Apple wants to do to my face.
I'd wager 100 USD right now that corporations will do thier best to prevent ownership because forcing people's or to the pay per use model with ads is far more profitable. Just like with laptops, soon you won't be allowed to have ownership rights and shortly after it will be illegal. Windows 10 bullshit was unimaginable just 25 years ago. These companies are furious that people got a taste of ownership. Agreed that fully autonomous may take 50 years, but there will always be a large amount of people who want to own instead of rent.
I still have no idea what you are even talking about. Voyager 1 is moving at 38 thousand miles an hour. A nuclear power source and a much improved ion drive could catch it in only a decade. Return in another 2, simple for a robotic probe only perhaps 40 years in the future. Lol it was a crappy chemical rocket from the 60s not alien tech.
Because I want to own my own car. I want control over the vehicle internal hardware and software, I don't want someone else's dirty vehicle, I want to add the accessories I choose and have easy access to them, I want to take it off road or on long trips where it will wait for me, I want it at my beck and call 24/7, I don't want monthly payments just off the top of my head. In an emergency or other high demand time I want a 100% shot at immediate vehicle access. You feel free living without a vehicle and only a glorified uber, paying far more cost per mile than vehicle ownership for the same number of miles, you and others may prefer this. Corporations like ford definitely want this yesterday. I, and likely many others, never will.
It's not a problem for a robotic probe and simple nuclear fission engines. The impulse efficiency (nozzle velocity of mass) is several orders of magnitude higher for many types of engines including ion drives and nuclear fission engines, both of which are old technology already..5C dosent factor into anything the voyager probe had a single chemical rocket engine provide the minority of the energy while a few slingshot flybys created the majority. We are chasing a model T ford let run down a short hill using a tesla to use a car analogy. .
Mod parent up. Also driverless cars run most of the miles on freeways and all in fair weather. A major cause of accidents is bad weather, which driverless cars don't run in, another is alcohol which autonomous cars won't be good at avoiding since the drunk drivers don't follow rules. I can't even find a study that can compare apples to apples as driverless cars don't run under the same conditions as piloted ones and very few studies seperate out weather or road type in accidents. Comparing pre planned safe city routes and highway drives in sunny conditions to the mess people deal with is not legitimate. We are probably at least 20 years away or more before a driverless car can do what a half distracted average driver can.
We are sick and tired of selling value at this price point. We don't easily know where you go in real time, can't divert you to areas we want you to go, or subject you to in vehicle ads, and after only a few years you are off a payment plan. We are going to fix this for you, and likely make it illegal to return to the old model of ownership and privacy rights.
Given they have historical value they will for sure be recovered by humans, and relatively soon. We know where they are and people will probably use thier return to demonstrate thier capabilities even if there isn't a finnancial reason. If I had to bet I'd say less than 500 years. By then we could send craft far faster and further making voyager less relevant.
Smith and Wesson have an awful lot to answer for then.
Absolutely not! They are a beloved company, a first class citizen. Not a second class 99% citizen nor a *shudders* European. My $0.02 is they fry him anyhow, facts be dammed.
Lmafo free market good one. If we did have a free market instead of crony capitalism my comcast bill wouldn't be insane for shitty service and my prescription drugs cost twice that of any other first world nation.
I'm all for American manufacturing but these high price tag incentives geared at foreign companies for a small number of jobs many of which are temporary looks like a bad idea. There are a supposed 3000 jobs for a 3B price tag or about 1 million dollars per job. It could take as much as 20 years to break even given the tax breaks. Quite frankly I'd be surprised if most of those jobs weren't in building the automated factory, to be discarded after 2-3 years just like the pipeline deals. The manufacturing jobs aren't coming back to the American people unless we count assembly line robots as citizens along with large corporations and actual humans.
Perhaps (and I know I'm absolutely insane), just perhaps, it would be better for Wisconsin to take that 3 billion dollars and start a universal basic income project instead. Instead of 3000 jobs (many of which are low wage and then dissapear) you could support 10,000 people at 21k a year forever at 7% interest.

Basically, do not try this at home.
So, I can still power my home with it, right?
