I can understand trying to get companies to stop gaming the system by shuffling their US profits to overseas holding companies to avoid taxes, but is this what this proposal is actually doing? If it is I'm all for it, but somehow I wonder if this is trying to tax overseas profits from overseas sales simply because the company is US owned. There was a raft of articles a few years back about US citizens having to renounce their citizenship because they were being taxed at obscene rates despite the fact that they didn't live, work, vote or even visit the US. Maybe its my latent paranoia but I wonder if this is the corporate version of this.

How is this Ubers fault? This is like suing a newspaper for not doing background checks on people sending/calling in classified adds when something bad happens in regards to them. Uber is just creating the meeting place for people to exchange a service, not providing the service themselves. People who use it have to recognize that fact and take proper precautions, as you would with any classified/craigslist/etc add.

While such an elevator system would use more power one of the inherent abilities of any electric motor system is the ability to use regenerative braking. You'd probably have a bank of super-capacitors in a utility room, when the elevator was going up it would use the capacitor bank and some power from the mains, when it was going down it would refill the capacitors. Even if you had to put the motors on the elevator car itself this shouldn't be an issue as we have centuries of technology (subways, trains, trolly cars, bumper cars, etc) proving that you can provide power to a moving transportation system and electric motors are quite small (the ones powering electric cars are about the size of a watermelon).

Rope and cable for elevators is a century old technology, I'm surprised they aren't using linear motors, standard electric motors or something else for record breaking skyscrapers. I can understand continuing to use cable for normal skyscrapers as it is a tested, widely available and is cheaper due to current production. But when dealing with such immense heights (1km) you would think someone would have the sense to develop something better suited rather then putting a small metal box on the end of a giant spool of rope/cable.

I've received all kinds of mail from them and DirectTV, but I've never got a call from them or Dish Network and I've never heard any complaints of people receiving calls from either. On the other hand I get all kinds of calls from car warranty and home security companies.

The grid fins may have contributed to the booster being off course from the pad but I have a hard time believing that they would have caused such an (apparently) abrupt change of orientation. Such control surfaces usually only function significantly at high speed, not at the slow speeds at landing. Think about it like putting your hand out of a car window, at 25 mph nothing happens, when you get up to 45 you get a little bit of push, but its only at 55+ when you can really have an effect.

Wow, when Musk said that it was a "hard landing" I thought he may have been exaggerating, he wasn't. Though it was VERY close. If I'm not mistaken the rocket is oriented pretty well (though is off the landing pad) just before it suddenly goes 45 degrees (presumably in an attempt to get to the barge) and slams into the deck. A larger pad would definitely help, but they may be able to tweak the navigation software to make it work.

Isn't this the same department that has been caught actively destroying their cruiser recording equipment, installed specifically because of abuse concerns? Unless the video is instantly uploaded to remote, third party servers and there are SEVERE penalties for damaged equipment or "malfunctions" then its not going to really mean anything. If officers think they're in the right they'll keep the footage, if they thing they did something wrong there will be an "accident" with it resulting in loss of the video/audio.

You can't change rough seas but you can get a ship that is equipped to handle them better (semi-submersible oil platforms for example) or make sea roughness at the landing platform part of the launch criteria much like the launch site wind/rain/electrical launch criteria.

I've heard that parachutes are fairly expensive, not horribly reliable (on the Ares-1x test flight 2 out of 3 failed), aren't really reusable and don't really decelerate spacecraft enough for a soft landing. There is a reason why most capsule spacecraft land in the ocean, landing on ground requires retrorockets.

If it was a fuel issue it could explain something. I've never seen a fuel tank camera before (though I am sure they have been flown before) yet at least the video I watched they gave a view of the second stages fuel tank (I believe) for quite a while after ending the burn. I wonder if they were trying to show the NASA guys that they could stage the rocket a little earlier (leaving more fuel in the first stage) due to an ample safety margin (there seemed to be quite a bit of fuel left.)

There are some working on a similar concept (Stratolaunch, Russian Re-entry Rocket Module (RRM), defunct Roton Rocket). To each their own, I would imagine that SpaceX didn't want to try to mix disciplines (rocketry & aircraft) and add moving parts. You can't just put a wing on a rocket and launch it, doing so adds immense drag and difficult to resolve aerodynamic forces so they often have to be stowed/folded into the rocket somehow. The only craft that I believe has successfully added fixed wings is the shuttle and that did it through brute force (SRBs) and a minimal aerodynamics (it screamed towards its runway at around 600 mph and then slams on the airbrakes and puts itself into controlled a stall to land at over 200 mph).

The fact that it made it to the platform itself is a major milestone, correcting whatever caused it to land hard (rough seas, hardware/software issue, ran out of fuel at the last second) would seem to be childs play compared to what was required to get to that point. Reentering craft usually have landing ellipsis of dozens if not hundreds of square miles and this thing landed on a 300'x170' platform. I look forward to the next (hopefully successful) test.

Several parts of the tunnel system were/are going to be built by TBMs. While they are a definite improvement on older methods of tunnel construction they aren't exactly what you would call fast and when things go wrong they go catastrophically wrong. The Seattle TBM digging a paltry 1.7 mile tunnel. It was stopped by a tiny metal pipe in its tracks and it will cost several times more than a brand new TBM to get things up and running again.

Boring straight through the planet may be (extremely) impractical, but shorter hops like the one I noted are not necessarily beyond current technology. Such a tunnel would be about 20 miles deep at most, handling the temperatures at that depth might be difficult (somewhere between 600 and 1000F I believe) but shouldn't be insurmountable. Again it would probably be wildly impractical from an economic perspective but not technically impossible as the "red stuff" is I believe at least 40 miles deep at least beneath the continents.
