As of March of this year, here is Tesla's MSRP list:

Decent range but too pricey.  I'll give it 5 or 10 years for the technology to become affordable.

Not sure what electric cars has to do with computer crunching Einstein. This thread is way off topic.

For goodness sake this topic was created to move off topic things from elsewhere and you still complain.  I'll talk about what I like, so spank me.

It's sad that people keep propagating the fallacy that electric cars are "dirtier" than fossil fueled cars.

They just show their ignorance and never read the published analysis.

Depends on how "dirty" your local electric grid is that determines the carbon footprint for an electric car.

in-less-than-a-decade-electric-cars-have-already-become-this-much-cleaner

And these reports and analysis is from 2-3 year old data.  Our grids have become even more greener since with even more deployed wind and solar generation.

But you have to think about what you're doing when you buy a car.  Even if your supply is 80% green and 20% dirty, what happens when you buy a car?  They burn more dirty to make the extra electrons for you.  The green is already maxed out.  All electric cars use dirty electricity.

Plus it depends where you live.  In California, you can get energy from solar.  Try that in Scotland and you'll maybe charge a phone.  There isn't sun here.  Just cloud.

What can you "delete" on a car?  How and why?!

I suspect he/they are talking about a number of software-controlled features including maximum travel distance/charge, self-driving features etc.

Removing the self driving feature from a car is theft.  If they really are doing this, Musk ought to be charged and jailed.  I don't see why it benefits the company anyway, all it will do it create bad publicity and loss of sales.

I am the owner of a month-old Tesla Y.  On the iPhone app which is a main interface to the car, there is a category called "upgrades". Were I to pay them $2,000, they would enable higher acceleration on the car.  I assume they could flip that bit back if they needed to.  So that seems to be a feature that could be deleted.

I have no intention of paying the $2,000.  My model Y long-range (the slower of the two currently offered Y models in the USA), has plenty of acceleration for me as it is.

As to why people buy the cars, you might try on the hypothesis that they are fun to drive.

I'm actively considering adding a model 3 soon.  That would mean we retired a 2002 Audi A4 and a 2006 Toyota Prius for a couple of Teslas.

Thanks, you've just made me decide to never ever buy any Tesla in my entire life.  You're telling me you have a car with the ability to have fast acceleration and it's artificially removed?  That is beyond a joke, a criminal act, and worthy of closing down Tesla for good.

Hi,

I need some help resuscitating a PC. Thats the most appropriate post i could find for this. I run Einstein@Home for a few years, but only sporadically on my daily notebook. Recently, I found my two old PCs sitting on a garage, forgotten. I thought those PCs no longer existed. So, i decided to put them to work for Einstein. It is my first time dealing with Linux.

The setup is:

Motherboard: ASUS P5KPL-AM SE

Processor: Intel Core 2 Quad Q9400 2.66Ghz  4cores/4threads

RAM: 1x 2gb DDR2 800Mhz + 1x 1Gb DDR2 800Mhz

GPU:  Sapphire HD 7750 Low Profile 

Main and only drive: 1x Kingston Datatraveller 3.0 USB Device 32Gb Pendrive

OS: Linux Debian 11 Bullseye x64

https://einsteinathome.org/pt-br/host/12932082

 

   I recently bought that GPU mainly because it was cheap, but also because i saw on Bottleneck Calculator it would work great on GPU heavy tasks with my CPU, it would use 100% of the CPU.

   Since i installed the OS and the GPU driver, its running ok, it runs 1 GPU task + 3 CPU tasks at a time, Im happy with it. The problem is that i see in the System Monitor that 2 CPU cores are running at 100% and the other 2 cores are fluctuating from 30% to 70%.

   My question is: Does that mean that my CPU can handle a more powerful GPU? And if so, how can i determine the fastest GPU i can buy for my CPU to  squeeze as much processing power as possible?

   Im also working on the second PC, which is older, Im seeing the same behaviour, it is using an Samsung 160 Gb SATA HDD, but for now i would like to focus on the newer one.

 

Thanks in Advance - Rodrigo Dantas

 

If you have free CPU time, a whole core-full, run another CPU task.

As for a more powerful GPU, yes, definitely.  You can always tell a GPU to run more than one task at once so it can use more than one of your cores.

I haven't upgraded from my Chevy Volt yet, but I am looking. Been difficult with the restricted production because of the supply chain issues.

My Volt is a series hybrid, that is the engine is not directly coupled to the front wheels but goes through the motor-generator.  I get around 45 miles of electric range when the temps are mild and I often go for long periods where the engine never fires up.  It does a engine maintenance run every 6 weeks for around 3 minutes if it hasn't turned on recently because of driving all electric miles to keep the engine fluids circulated. Most of my driving is local so always running full electric.  But I have the engine and gas tank to go for long commutes or traveling to visit relatives with no range concern.  I gas up about twice a year.

Careful, gas goes off if you keep it too long, from memory it's about 6 months to a year.  It literally smells wrong if you sniff the tank, and is very bad for the engine.  You'd be better keeping the tank quite empty and just putting small amounts in when you need it.

The first thing I noticed when I got my Volt was the acceleration.  That gives a smile every time I punch the throttle pedal.  In Sport mode, it launches even faster.  But it has a bit of torque steer when you do since it is front wheel drive so you need to compensate a bit to keep it going straight.

One of the main reasons I'd go electric, for acceleration.  I love front wheel drive.  No tail happy crap like BMWs.  A racing driver might well be able to make good use of RWD, but most drivers find it annoying.

Electric and ICE/electric hybrid vehicles can be tons of fun - the low-rpm torque of electric motors makes for great acceleration.  I have to concentrate to stay reasonably close to the speed limit when driving my 2009 Chevy Silverado 1500 4x4 hybrid pickup truck around town.

I don't, I just ignore the limit.  Haven't been done for a decade.  I've got very good at spotting the bacon, and so has my satnav!

That's why there is a fuel maintenance interval also.  Forces you to burn off the gas in the tank every year to keep it from going stale.  Or add fresh gas to boost the stability of the remaining gas.  Also only premium gas is recommended for its enhanced storage characteristic. I take around two long family trips a year so only have had the FMM mode forced on me once.

Still will be nice to not have to visit the fuel station at all.  Nice to have a fully "fueled" car in the morning after plugging it in after getting home from work and it recharges overnight when the rates are cheapest.

So fully battery electric vehicle is next for me. Lots of choices now.  Tesla, Ford, Chevy, Kia, Hyundai, VW etc.

Oooh fancy!  My father's normal gas car got slightly stale gas as he never uses it.  So I used it and topped it up as soon as it had dropped a little, and so on until it was fresher.

And all costing way more than the savings you make on gas.  Nice idea, but the tech is in it's early stages.  Batteries have to get a quarter of the current price before I'll bother.

And there's another thing people never consider.  Electricity is cheaper just now because the government puts a huge tax on gas.  Once everyone is on electric, they're gonna tax your electric car, then how much will it cost to run?
