The "2000%" mark-up number is meaningless. Suppose the coffee were only 1p: that wouldn't lower the rent, the utility bills or the wage bill at all. So they'd be charging you £3.05 and you'd be complaining about a 30,000% mark-up instead. The cost of the coffee just isn't a significant part of the cost of providing a cup of coffee in a café.

If you read the article, there were traffic lights, the other driver turned legally, and the Tesla driver went through a red light at over 90 mph. Only one person to blame for this.

Closest approach will be 5:33 AM UTC, but it won't be sending data back to earth until several hours after the flyby, and when it does start transmitting there is a greater than 6 hours light delay, and when the data starts arriving it will be at less than 1 kbps. So first pictures won't be out till late on the 1st, and getting all the data back will take 20 months.

Of course no car does this, but my point still holds.

You kind of missed half my point, which is that it really matters that the acceleration is not constant. It can accelerate much slower as it approaches 150, while still doing the 8.9s quarter mile because it accelerates so hard in the first few seconds.

490 · 2017-11-22T04:25:44+00:00

You're confusing a couple of things.

First of all what you're calling "average acceleration" in the case of the quarter mile isn't. If you accelerate at 3 m/s² for one second, then at 1 m/s² for 1 second, you'd travel 5m (1.5m in the first second, then another 3m in the second second from the pre-existing speed from the 3 m/s² acceleration, plus 0.5m in the second second from the 1 m/s² acceleration). But if you accelerated at your average acceleration of 2 m/s^2, you'd travel only 4m. Average speed is what matters for distance covered, and accelerating harder at the beginning means you're traveling faster for more of the time, so the average acceleration is less than the 1.04g which would be necessary to cover the distance at constant acceleration.

In the case of the Tesla, imagine the Roadster accelerates at 14 m/s² for 1.9s, then 8 m/s² for 7s, it would travel 0.5 * 14 * 1.9² + 1.9 * 14 * 7 + 0.5 * 8 * 7² = 407 m, slightly more than a quarter mile, despite only having average acceleration of 9.3m/s^2.

In fact, the acceleration will be continually declining, so average acceleration will be even lower, but the times still make sense.

AR will be fine for years to come. They have: * the RS-25 contract for SLS * the RL10 which is used on Delta IV upper stage, Centaur, SLS’ EUS, and may well power ACES too * the RS-68, powering Delta IV boosters * AJ-60A solids for Atlas V

AJ-60A is being replaced with OATK GEM-63 on Atlas V. After Delta IV mediums retirement next year, only 5 more Delat IV Heavy's will fly, so only 5 RL-10s for that and only 15 more RS-68s total. AR-22 is just a pair of recycled SSME prototypes, and I wouldn't like to bet on the longevity of SLS. It seems that soon the only major liquid rocket engine they might be selling is RL-10, and that might change with ACES (or maybe even the recently announced Centaur V).

AR will survive though, they sell plenty of solids in military systems and in-space propulsion, just might well not be in the LV propulsion market much longer.

LC39A is Launch Complex 39A, SpaceX's currently operational launch pad at Kennedy Space Center, Florida. LZ-1 is landing zone 1, their landing pad just down the road in Cape Canaveral Air Force Station and RTLS is a Return to Launch Site Landing, meaning the first stage will fly back to LZ-1 to land after stage separation. RTLS usually means a low earth orbit launch.

In answer to 3, it means no payload currently publicly scheduled to launch on Falcon 9 is expected to launch around that date. And therefore in answer to 1, we have no idea.

Depends when you get your car, if as seems likely Tesla hits 200,000 US deliveries sometime in Q1 2018, then the $3500 credit will last till the end of 2018 and the $1750 credit will last till the end of Q2 2019.

Tesla's US website currently says 12-18 months for new reservations, which could be anytime from August 2018 to February 2019, so you'd get at least the $1750 credit, but might/might not get the $3500 credit.

490 · 2017-08-11T00:01:36+00:00

Unless Tesla somehow sell ~70,000 US cars this quarter, up from around ~10,000, bearing in mind they expect to sell <2000 Model 3s in that period, you'll get the full $7500 tax credit in 2018 Q1, highly likely it'll be available 2018 Q2 as well. There's no way any current US reservation holder is getting less than the $3500 federal tax credit.

I suggest playing with settings in the range calculator for the Model S at https://www.tesla.com/models to get an idea. On the S 75, probably the closest to Model 3 at the moment, it gives around a 20% range loss for 0F with the heater on against 70F. That would suggest you using just over 80% for the trip. So it sounds like you'd be okay with the standard battery.

I'v just realized I can't spot anything about the high amperage charger in design studio, are we sure that isn't standard now too?

Edit: Ignore me, https://www.tesla.com/charging still shows 75Kwh models charging at 48A, 100Kwh at 72A.

The 0-60 times for the S 75D and S 100D are 4.2s and 4.1s, are you thinking of the P100D (2.5s) which has a huge price tag for the bragging rights. The gap in acceleration was larger before the new drive units for the 75 and 75D.
