At the end of the day it’s just a very large die casting machine. To switch out the part it is casting requires making new dies. It is expensive so you don’t want to be doing that a lot, but these machines are going to be probably doing 500

Not to mention the efficiency of converting the stored Hydrogen to power. It’s hard to beat the efficiency of a battery and electric motor.

Not sure why he called it “TheFacebook”. That was an early name used way prior to even 2005. ChromeOS was released in 2010/2011.

Now that it’s literally all the same can we please get an iPad Pro that runs Mac OS when docked into a nice keyboard/trackpad base?? I would get rid of my non-work 13inch mbp if this was the case.

Besides the economic slowdown I suspect some of this is also the Model Y is eating into sales of the other 3 and this price adjustment is mostly to differentiate them a bit more.

Not sure I agree here. The Tesla technology does quite well with a camera based sensor suite and a moderately priced custom silicon. It is rapidly getting better and they are logging an order of magnitude more miles than Waymo which is stil

Theres a lot of B.S. in your post but I just wanted to point out that Elon constantly praises the Tesla and SpaceX teams on Twitter, Quarterly conference calls, Podcasts and in other investor presentations. There is for sure a cult of perso

The lack of dual power supplies and remote power on/off and good PXE support is crazy for a rack mount computer (won’t even dignify it by calling it a server).

Wow like 10 minutes before I saw this post I was running into the same issue.

Interesting that no one to my knowledge has built an architecture where sram is ‘memory’ such that it would be transparent to C code but no slower dram is used. 32MB is more than my 1998 computer had.

It will still be power hungry and mess up aerodynamics even if it is smaller. Tesla is looking at the entire picture of autonomous + EV which IMO is a better strategy.

I am sorry you are so misinformed. Lithium is a common abundant resource and battery packs are easily recycled but more importantly there is a financial incentive to do so. Manufacturing technology for cells is improving rapidly. Much fast

Theres also this thing: https://www.slashgear.com/hydrogen-fuel-cell-ev-charger-afc-... I have no idea if the economics of that actually will work.

It also serves to preserve the current refueling experience from fuel delivery to point of sale. Electric cars are mostly charged at home and at work/parking areas which flips everything on its head. There are a lot of industries threa

You don’t really have to be “rich” to afford this roof. It’s a totally sensible investment that actually pays for itself between 10-20 years and you can use a loan to finance it. It’s also very sensible for new home construction which is al

Terrible article. Yes it bounced back off of the lows but it’s still not close to profitable and well under the IPO price. Most of the employees got burned and have not recovered.

Yes this would be a challenge. It may not be able to operate at full speed for the entire duration of the trip, but significant portions it probably could.

Not at all. A fast ferry from downtown NYC should take around 20 minutes to get to JFK. It would be easy for them to integrate a marine terminal there, just as they are going to do at LaGuardia airport. It’s a hell of a lot more practical

Helicopter service makes no sense to me. A very fast electric ferry from Downtown and one of the Piers near midtown... That makes a lot more sense to me.

It depends what speeds make the motor run sub-optimally for a particular vehicle. The range 0-80 MPH is sufficient for almost all normal driving. If you want to make an efficient track car that can operate at high speeds optimally by all m

Not 100% accurate. It is a new battery pack but still based on the 18650 cells. Tesla battery packs have a numerical code which was incremented for the packs in the raven models. The most pronounced new feature is the ability to charge at

Routes may rarely change overall but there is a ton of daily maintenance, closures and re-routing that happens on the NYC subway system. A paper map is probably good for generally learning the system, but not very useful in the station when

Highly cynical response. It pretty clearly states in their reply that one of the main motivations is to eventually display more real-time information like outages and maintenance. Not easy to do with static paper maps. In fact when I was li

Again, technology is not static. There are lots of folks working on the brake dust and tire wear issue. You should be happy to know that regenerative breaking on BEVs results in a lot less brake dust, although currently more tire wear due t

Miles driven should go up but with far fewer vehicles, since with autonomy cars can operate almost 24/7. But point taken, we will need those autonomous cars to be BEV and use renewable power.

“Still, in most cases an electric car is slightly less bad for the living planet than a comparable car with an internal combustion engine – if you can afford to buy one.” Bad article all around. There is bias in that statement alone referen

Why not invest in new solar power generation instead of removing co2 at this point.
