From what I understand, the benefit of autonomous truck driving is not eliminating the drivers, it's fuel economy. By having a convoy of trucks spaced optimally apart, the trailing trucks can benefit from the aerodynamic "draft" created by the first truck. Humans simply aren't capable of maintaining those gaps safely.

Here Comes the Keurig of Everything 270

Tekla Perry writes: Keurig made a huge business out of single-serving coffee machines. Now, as more complex machinery shrinks in size and cost, many companies are trying to duplicate that success for other types of food and drink. Startups are introducing the Keurig of cocktails, the Keurig of Jell-O shots, and the Keurig of dinner (it makes stir fries, stews, and risottos). The question is: does having a single- or limited-purpose device make really make sense for consumables that aren't coffee? Counter space is not infinite, and most people want more variety out of their lunches, dinners, and nightcaps than they do for their morning pick-me-up. (Also, let's retire this metaphor before we get a Keurig for cats.)

I'm not aware of any seats on a CRS Dragon. However, I do remember an astronaut stating that a human stowaway would make it safely to earth aboard one. It certainly has some life support systems, because it carries mice to ISS.

I think since the Space Shuttle program, NASA has become much more concerned with safety. Therefore, a Dragon 1 with seats won't do. They want redundancy, specifically abort capability from the launch pad to orbit. Which is something the Space Shuttle never had. Before Challenger, it was LEO or die.

I wouldn't be surprised if NASA has a secret evacuation plan that involves using a Dragon as a lifeboat.

Which is a stupid cash grab really, as my 2002 tests just as good now as it ever did.

Not really, vehicles deteriorate and may begin to fail emissions standards. You are lucky to have a dependable vehicle that gets the same results after all these years. They are usually testing to see if your vehicle is functioning properly. In Illinois they just do an OBD scan to make sure no fault codes are present for the O2 sensor and catalytic convertor. However, even a perfectly maintained vehicle should show some deterioration in emissions performance.

We're talking about a bunch of sloppy old pickup trucks with little or no emissions controls, usually literally nothing but one O2 sensor, an EGR, a PCV, and a catalyst.

I develop vehicle emissions system for a living. An O2 sensor and a catalyst will get rid of the vast majority of emissions from a spark ignited vehicle. Little or no emissions controls would mean 1970s era cars. Think carburetor and no catalytic convertor.

No, SolarCity doesn't lease the panels back to you - they sell the power from the panels to you. And they control the rate you pay and have the ability to raise it annually (up to 2.9% per annum).

Solar city has a variety of financial plans available. I believe you are referring to the "SolarPPA" option, but leasing panels is also an option.

ESPN charges cable providers around $12/month/subscriber.

The number I've been hearing is $30/month/subscriber. However, it's tricky to nail that figure down, because Disney sells ESPN as a package with all of its other channels. That's the problem. Once it becomes unbundled, you find out how much it really costs.

The reason why diesel engines have problems with NOx emissions is because the high temperatures and pressures in diesel fuel cause the nitrogen in the air to react with oxygen.

The high temperatures and pressures in the combustion chamber cause the nitrogen and oxygen in the air to react with each other to form NOx.
