Hi actual scientist here. I have zero intention of boycotting either of these publishers. In fact I’m about to publish a paper of research funded by public money in an Elsevier journal.
I will not be publishing it open access nor will I post it on arXiv. If you would like to read a copy, you can buy the article, go to a library, or submit a Freedom of information act request with the funding agency.
Quoted the parent since their message needs to be seen. It’s sad how far slashdot has fallen when scientific fact is modded down by people that believe in myths.
NYC geology is completely different than LA geology.
The boring company half assed tunnels meets zero of the safety requirements that the LA subway meets. Here’s what an actual expert in tunneling had to say.
So for those of you still interested I did a little digging around and found the permits TBC used to construct the Hawthorne Tunnel and Elevator, be warned they are 160 pages and 157 pages long respectively. See below:
http://hawthorne-ca.granicus.c...http://hawthorne-ca.granicus.c...
A few interesting things that jumped out at me when reading through these:
1. When detailing planned operations for the test tunnel TBC specifically stated that the public would not be allowed in the tunnel and that the skates would not be occupied while being tested in the tunnel. I haven't been able to find anything modifying this, so I'm not sure how Elon is allowed to give rides to people in this tunnel.
2. The tunnel fire safety plan requires everyone entering the tunnel to be provided and trained in the use of a W65 1 hour self rescuer, and only calls for the of combination fire extinguishers for fire suppression. This works for a test tunnel closed to the public, but its worth pointing out that NFPA 130: Standard for Fixed Guideway Transit and Passenger Rail Systems requires things like fireproofed ventilation systems, automatic fire detection, standpipe and sprinkler systems. Emergency tunnel egress points to the surface every 2,500 ft or cross passage egress to another tunnel every 800 ft. I'm curious how Elon will fit all these features as well as the skate within his stated 12 foot tunnel cross section.
3. In detailing their construction plans TBC said they anticipated tunnel advance rates of 60ft/day and a construction duration of 5 months. So they definitely fell short of that goal. Ironically perhaps it seems they came up with the 60ft/day number based on what the TBM performed on previous tunneling projects. So TBC managed to tunnel at less than half the speed the previous TBM owners Super Excavators did with the same machine. Now its not entirely apples to apples since geology is different, and TBC supposedly spent time tinkering with the machine.
4.They have the spec sheet for the TBM they're using attached towards the end of the tunnel permit. It states the machine as delivered had a total installed power of 1400hp or just over 1MW. Additionally, the machine is intended to be fed directly from the grid apparently because it is listed as having a primary voltage of 13.2KV three phase. This is interesting to me because Elon has talked about wanting to make these machines a)more powerful and b) run off of batteries. The permit restricts TBC to working between the hours of 7AM and 7PM or twelve hours. To run the machine continuously during this period off a battery you would need 12MW/hr of storage, a Tesla powerpack like those installed in Australia has a storage capacity of 210KW/hr each so you would need 58 fully charged powerpacks (rounding up from 57.143) to run the TBM for a full 12 hour shift. Assuming you placed these all side to side at 32.4"wide you end up with a battery 156.6 feet (47.7m) long without leaving any clearance in between units. Additionally you have a weight of 76.7 tons (69600Kg). Mind you this is all per the manufacturer's spec sheet, Elon has talked about wanting to increase the power considerably, so I am left wondering why he wants to make it battery powered when it would take a massive battery installation to last a single shift, especially considering the machine can be plugged directly into the grid.
As far as tunneling speed, I suggest you look up the Gotthard Base tunnel. It was built in ~16 years. At the rate it took the incompetent boring company to build their smaller tuner with zero safety measures, it would have taken them 22 years to go the same distance assuming they used two machines.
Solar City was then sold to Tesla, who sold the rights to this project to someone else
This is a complete fabrication. From the article because you have a reading comprehension problem,
The town sought bids for the solar project in 2015 and selected SolarCity from among a half-dozen companies. Thanks to state clean energy incentives, the town expected to save $183,000 on its $2 million annual electricity bill.
The project hit a snag, however, when National Grid informed SolarCity and the town that the California company would have to install specialized equipment to ensure the safety of the utility's network. Jones said SolarCity and the town negotiated with National Grid to reduce the cost of this equipment.
Around the same time, Tesla completed its acquisition of SolarCity. Jones said Tesla never moved forward with the solar array, and this year informed the town it wanted to break the agreement.
The town could have taken Tesla and its CEO to court but, "we would have been in line with everyone else trying to sue Elon Musk, you know?" Jones said.
So the town tried to salvage the project, and convinced Solar Liberty to consider taking over from Tesla.
They do not have 400,000 pre order. A reservation is not an order. The vast majority of those reservations were canceled. And only 20% were turning into actual orders.
Let’s compare the body count of Tesla's inferior system vs. the superior super cruise.
Tesla: 3 dead. Countless accidents.
Super Cruise: 0 Dead. 0 Accidents.
You missed the interest you’ll pay on the loan. For a $45,000 car let’s assume a 20% down payment. That gives you a loan amount of $36,000. Rates for a 60 month loan right now are 5%. So your $45,000 car actually costs $49,762.
Since you can presumably afford a $9000 down payment for the Tesla, we will assume the same down payment amount. So the ICE loan is only $13,000. Also since you can presumably afford the $679 monthly payment for the Tesla, we can shorten the ICE loan term to 20 months. Making your total interest paid $576 and change. That puts the total cost of the ice car at $22,576.
The difference in upfront cost at $27,186. At current gas prices of $2.50 per gallon, that extra difference will buy you 10,874 gallons of gas. At 30 miles per gallon, you break even at 326,232 miles. Long after you will be sending that car to the junk yard and long after you will have to pay for an extremely expensive replacement battery on the Tesla.
You realize that Sandy Munroe, the guy you're citing, later changed his mind and called the vehicle a symphony of engineering, among other high praise?
Irrelevant. The Saturn v always has been and always will be bigger than the falcon heavy.
By the way it’s pretty telling the musk doesn’t want to fly to the moon in his death trap.
World wide statistics cover all driving conditions. Self driving only cover carefully selected conditions. When you limit human driving stats to just same carefully selected conditions humans come out light years ahead over self driving gimmicks.

Go home Rei, you're drunk!
And take a cab not your piece of shit tesla.
No where does it say you need to be in control and that you are still in charge.
Not stopping is creating the dangerous situation you fucking stupid dumbass. I hope retards like you get run over.
They do not have 400,000 pre order. A reservation is not an order. The vast majority of those reservations were canceled. And only 20% were turning into actual orders.
Tesla’s have higher repair costs than ICE vehicles.
They aren’t even refunding the $1000 deposits people put down to reserve a reservation.

Enhanced Autopilot is still and option, and drives millions of miles without issue.
Except for issues like driving into the back of bright red fire trucks.
Low intelligence, big ego, thinks he's an engineer when he's really a moron,... You just described elon musk.
Does change the fact that 100% of electric vehicle fires are teslas.
The shit tesla is better than the leaf at spontaneously combusting due its shit build quality.
You realize that Sandy Munroe, the guy you're citing, later changed his mind and called the vehicle a symphony of engineering, among other high praise?
He literally said no such thing.
Irrelevant. The Saturn v always has been and always will be bigger than the falcon heavy. By the way it’s pretty telling the musk doesn’t want to fly to the moon in his death trap.
Huh, 20 cases and 689 docket entries? Let's see what happens when we substitute another random billionaire -
Bill Gates: 6 cases 25 dockets. Donald Trump: No results.
Wait 10 1/2 weeks.
When Tesla announces their next round of losses.
When is the full self driving gonna arrive? Or that cross country full autonomous trip? Or the $35000 model 3?
Or where that secured funding is?
Tesla doesn't have dealers. They destroyed the evidence directly.
Tesla has had recalls on 100% of every car they have ever manufactured. No other car company has a shit record like that.
The space shuttle had 135 launches and only one launch failure giving it a 99.2% launch success rate.
Could it be that tesla hired cut rate transporters because they were trying to save money since they already lose money on every car they sell.
Here's your citations. tesla owner nearly burned to death due to shit design. tesla almost kills owner when it rams concrete barrier. Notice how all the non-teslas cars driven by people smart enough to not buy a piece of shit tesla all avoid the accident? tesla almost kills driver and multiple fire fighters due to their shit system. tesla nearly decapitates passengers by driving into truck.. tesla delivers accident waiting to happen to owner due to shit quality control. tesla cuts corner by not having a proper gauges in front of driver. glued on iPad they use instead causes deadly shards of glass to be thrown at occupants.
World wide statistics cover all driving conditions. Self driving only cover carefully selected conditions. When you limit human driving stats to just same carefully selected conditions humans come out light years ahead over self driving gimmicks.
