I don't want a year or a month of MLB. I want to buy by the game. Charge me a buck or two for a single ball game. No monthly or annual fee (above the Amazon Prime fee), and let me just watch what I want, when I want, and pay for just that. Hell, I'll throw in an extra buck per game if you fill the "ad space" time with a single Amazon ad and then run sports highlights during the teevee timeouts.

What needs to be done is build more newer cities and job opportunities in them (cheaper outsourcing anyone?) so the infrastructure in the bigger cities gets a chance to catch up.

That's one way to do it. Another is to look at what's causing the emissions upwind and curb them. Could be power plants. Could be dirt roads. Could be the burning of all the litter/household trash. Could be two stroke engines. Now do two things: 1. implement (stricter) standards on pollutants for new equipment, and 2. work on retrofitting existing equipment to tighter emissions standards.

You don't need a new city to require motorcycles that pollute less or to improve the electric grid to burn less coal in central steam plants and less diesel fuel at local gensets.

Comment Cost to operate (Score 1) 344

That's helpful, but you've failed to include fixed operations and maintenance (O&M), fuel, variable O&M, and, most important perhaps for nuclear, ongoing capital expenditures (capex) necessary to keep the thing running. We're seeing nuclear units retiring in America right now because the $30/MWh they make on the energy market isn't enough to cover their per-unit-energy ongoing costs. When you include the ongoing costs to keep them running, it's far less obvious that new nuclear power plants will be money makers. Even less obvious is that they will make more money than a combined cycle gas plant, a wind farm, or a solar farm.

Where do you think the power for that electric car comes from? 75% of that power on average comes from burning coal.

Who's average? The percentage of electricity generation fueled by coal in 2015 was 38%. (EIA source, with trend) Even regionally, electricity generation from coal sources exceeded 50% in only one region in 2015 -- the Northern Plans, which represent an area defined in the north by North Dakota to Wisconsin, by the south from Kansas to Illinois (excluding Chicago Land), and less than 10% of total generation in tUSA. And even in the Northern Plains, it was less than 75%. Please show up with data and facts, not horse apples.

lobbyists that prevent Tesla from selling in Michigan without going through dealerships

Lobbyists have no such power. Legislators have that power. Lobbyists advocate positions on areas of public policy, legislators write the laws and the governor (in the case of state government) signs or vetoes. Also, Schoolhouse Rocks.

Again, lobbyists have no such power. legislators write laws, departments with heads appointed by the executive branch draft and execute regulations, and judicial or quasi-judicial agencies determine adherence. See: Rocks, Schoolhouse.

Nope. That billboard was put up by, "a global nonprofit organization founded for the purpose of spreading peace in a hurting world." They may have ideas that align with the Democratic Party, and members and donors may be Democrats, but the billboard was decidedly not "put up [by] democrats[sic]."

...a half-hour travel time between Stockholm and Helsinki, which is the equivalent of about 300 miles.

"The equivalent of about 300 miles"? What does that mean?

Oh, it means "about 300 miles". Or even "a distance of about 300 miles". Right. But this is a 'technical' topic, so we need to use more and bigger words. The best words.

Unless there's some sort of weird space-time physical equivalence principle the authors are alluding to, in which case a half hour is actually 300 miles long.

Comment Re:What is the turnover/new hire rate? (Score 1) 200

Are you suggesting that the headcount at Facebook has been static? Facebook has grown from 4k to 12k employees in the past 3 years. In your example, if Facebook had hired 50% females in 2013 and 2014, and nobody ever left, it would have gone from 33% to 44% over those two years without putting a thumb on the scale at all. I'm not arguing that this is what Facebook should have done. I am arguing that your example, while perhaps applicable to other companies, absolutely does not apply to a company with the tremendous headcount growth that Facebook has had.

Comment Re:Hyperbole (Score 1) 175

But regarding their testing, it was certainly a small scale test of known technology, but you underestimate the value of such tests. There's massive amounts of theoretical aspects they have to plow through first, move gradually to small scale live tests and finally piece it all together in one big PoC. After the small pieces are theorized and tested, it takes exponentially less time to piece them all together in the end.

I wouldn't say I underestimate the value of small-scale tests so much as I would say that Musk and company have been deliberately obscure about exactly what they were testing, and have been downright misleading about the distance between where they are now and what they claim they will be able to deliver. We were shown a dog-and-pony show constructed to meet an artificial publicity deadline, not a well-explained demonstration as part of a clearly-elucidated development roadmap.

When I read comments like yours, it reminds me of anti-innovation corporate voices I have to battle against on a daily basis.

Hmm. Do you misrepresent your progress and conceal the nature of your accomplishments to your corporate masters too, then? That could be your problem.

Look, I'm a scientist in an academic setting, but with private-sector collaborators. I do both "pure" and "applied" research. I contribute to both peer-reviewed papers and patent applications. I can tell the difference between healthy skepticism and blind anti-innovation. The problem with Musk's Hyperloop demo isn't the idea, or the technology, or the dream--it's that he doesn't tell us what the demo is actually doing. It's like writing a scientific paper that starts with the usual Abstract and Introduction, then jumps straight to a one-liner Conclusion and a big Discussion about the implications of the work and all the cool stuff that's going to happen in the future. He just skipped over the Materials & Methods and the detailed Results. We aren't told what we're actually looking at or what it can really do, just to take on faith that it's awesome. That's my issue.

Mod parent up.

The "first successful test" appears to have been a small test sled on a short, low-speed test track. Yes, they showed they could drive a piece of metal with a linear induction motor, but that's just demonstrating an application of known technology. Vancouver's SkyTrain has been using linear induction propulsion since 1985 as part of a regular, boring, functional public transit system. Similar technology appears in Toronto (the Scarborough Rapid Transit line), New York (the AirTrain JFK airport link), and at least a handful of other sites.

Practically speaking, one could have done the same demo by taking a 30-year-old SkyTrain car, stripping the body and seats out, and flipping the induction drive unit sideways to be compatible with the vertically-mounted induction track shown on the Hyperloop demo system. (You'd get great acceleration, too, since you can dump much of the car's weight--and you wouldn't care about the components surviving for more than a few seconds of photo op.) Maybe there were major technological advances under the hood, but the breathless hype all glosses over any meaningful description of what might have been accomplished.

"Alien-hunting telescope"? Really, guys?

A large-scale pure-science project. A tool that will advance modern astrophysical and astronomical research. A landmark technical achievement.

But it came from funny-looking furriners (not just funny-talking, like them ones from Yurp). So we must be sure to cast the headline in the most derisive terms possible. It's not a research tool that shoestring SETI projects will be able to snag a bit of time on--no, it's an "alien-hunting telescope".

I mean, my God--snippets of Aricebo's time have been used for alien-hunting (and alien-spamming) for decades. It was used to send publicity stunt messages to M13 in 1974, and to some nearer stars in 2009. SETI@home users have been crunching Aricebo data looking for little green men since 1999. And yet, oddly enough, no one ever seems to refer to Aricebo as an "alien-hunting telescope". Why is that?

You'd rather break someone else's bones than total a car where everyone escapes injury free? That's messed up.

Heck, it probably even falls down (er...) on a strict monetary cost basis. A broken bone caused by a vehicle colliding with a pedestrian likely has a bunch of associated soft tissue injury, which can lead to all kinds of expensive-to-manage (and -treat) damage. The straight-up hospital bills plus lost wages for pedestrian victim can very easily pile up to more than the insured value of a car--making those priorities a net loss for society even if we assign no value at all to preventing pain and suffering.

Of course, it's also silly to pretend that the car is "smart" enough to confidently and reliably predict what will be a moderate injury versus a potentially-fatal one. The car doesn't know if a wound is going to suffer a serious infection. The car doesn't know if a bone fragment is going to sever a major artery. The car doesn't know if the pedestrian will suffer a serious brain injury when her head hits the pavement. Pretending there's a firm choice between totalling the car and non-permanent injury is a fiction--the choice is between totalling the car and a risk of serious or fatal injury.

I salute your honesty, but in a situation where the outcomes are known in advance, you'd prefer breaking somebody else's leg to a total loss on the car?

Even if the leg heals up fully, the pain could be tremendous. The inconvenience massive -- perhaps the victim lives on the 3rd floor? How about work -- lots of people require mobility for their job (think: waitress). Oh, yeah, and the financial cost to repair the leg could easily outpace the cost of replacing the car.
