15km isn't that far out. You can still use oxygen-burning jets at that altitude if you design them right. The SR-71 went up to 24km. Amature high-altitude ballons can break 30km and might get out to 50km if they try hard enough.
If this thing can plausibly get out to 100-200km, they might have something, but 15km isn't very impressive for what it needs to do.
Photosynthesis is pretty bad. It uses only a narrow range of wavelengths, which cuts it down to 45% right from the start. The chemical reactions work out to about 25%, max. Overall theoretical maximum is 11%, which goes down to 3-6% under realistic conditions. Source:
Carnot Efficiency goes up with the temperature you're adding to the system. At the temps nukes run at, it can be quite a bit better than 40%, and a lot better than the best photovoltaic cells in a labratory.
The most efficient use of solar power doesn't come from photovoltaics, but from solar reflectors, which are also limited by Carnot Efficiency.
She did not rule to deny the promotions regardless of the test results. She ruled that the city had the right to throw out the test results if they so choose.
Agreed that it's eventually going to be on the northbridge. However, SAS isn't there now, either, and SSDs are still likely to saturate that bus in the near future.
SATA vs SAS is a different debate than IDE vs SCSI. Even on servers, it's easy to now justify the cheeper standard compared to the older standards. Not in all cases, of course, but far more often than you could with IDE.
SSDs aren't (currently) aiming for the price/GB crown. The power instability is manageable. I'm not saying it's for everyone, but there's definately a niche.
Side note: 0-60 mph in 4 seconds flat. Ummm... doesn't the Tesla Roadster do it in sub 4 and its a consumer vehicle... just a thought
Yes, and the Wrightspeed X1, based on the Ariel Atom, does it in just over 3 sec.
Then again, straight acceleration isn't the most important thing in an endurance race. Audi has been cleaning up the big endurance races of late with their diesel engine, not by being the fastest, but by good team strategy and needing fewer pitstops for fillups.
What's the energy efficiency of the horse's food vs work output? Even a sleeping horse consumes energy just to maintain body temperature. At most, a car will trickle a bit off the battery for a few things.
How do you make the food for the horse? How do you take care of the droppings they leave behind?
Even including climate change, fossil fuels beat animals by a lot.
OBD-II is the spec. However, manufacturers tend to add all sorts of extentions and lock-out codes. With the right legal fanagiling, you could argue that these are copy protection schemes under the DMCA, or maybe just trade secrets. Either case is a government-enforced monopoly.
Washington was against political parties, and said so in his Farwell Address:
In contemplating the causes which may disturb our Union, it occurs as matter of serious concern that any ground should have been furnished for characterizing parties by geographical discriminations, Northern and Southern, Atlantic and Western; whence designing men may endeavor to excite a belief that there is a real difference of local interests and views. One of the expedients of party to acquire influence within particular districts is to misrepresent the opinions and aims of other districts. You cannot shield yourselves too much against the jealousies and heartburnings which spring from these misrepresentations; they tend to render alien to each other those who ought to be bound together by fraternal affection.

However combinations or associations of the above description may now and then answer popular ends, they are likely, in the course of time and things, to become potent engines, by which cunning, ambitious, and unprincipled men will be enabled to subvert the power of the people and to usurp for themselves the reins of government, destroying afterwards the very engines which have lifted them to unjust dominion.
But not everyone agreed, even back then. Washington was the first and last President to not belong to a major political party (except, kinda, John Tyler, who was thrown out of the Whig party).
I haven't seen this particular video, but in general, he often cherry-picks examples. That's not to say that US car makers haven't made a lot of turds, but he often makes ridiculous comparisons. Like comparing a 1.3L Turbo European car to a 2L NA US car and saying how crummy the hp/weight ratio is.
We don't know much about the weather ten days from now and you think you know about the general climate a hundred years in the future? Are you serious?
Yes, because I understand the implications of Chaos Theory. Namely, the Butterfly Effect prevents you from making specific predictions a month from now, but still allows you to make more general predictions years or even centuries in the future. This is why Climatology and Meteorology are separate disciplines.
The Club of Rome misunderstood how an increase in the price of oil due to shortages means that some reserves suddenly become profitable to exploit. That doesn't mean we won't eventually run out or that we won't cause other problems along the way.
We're actually overdue for a new ice age cycle. In fact, our CO2 output may have broken the cycle. Which is probably a good thing, but that doesn't mean that even more CO2 is still a good thing. We've overcompensated.
While it's possible for the climate to change quickly, it's usually due to some specific event, like an asteroid impact. The Earth by itself would change over the course of thousands of years. Since we can rule out asteroid impacts and pretty much any other drastic climate event, our own activity over that time period is the only thing left.
Further, in the 1970s (before this issue became politicized), the only debate between climate scientists was if the albedo effect of particulates would drive temperatures down faster than CO2 would drive it up. By the '80s, many countries had put limits on particulates (such as mandating emissions on cars), thus guaranteeing that CO2 would win the tug-of-war on tempature. I'm happy that particulates are at least limited (since they have a direct effect on the human respiratory system), but CO2 needs to be delt with, too.
Even if you could get all of humanity to agree, it would be difficult to correct the data against other events, like volcanic eruptions and sun activity.
The ultimate goal of these models is to make solid predictions on the effects of climate change. As of yet, few if any are much more than toys. They're useful toys in so far as they help move us towards a good model, but toys just the same.
However, the fact that climate change is occuring and directly related to human activity is based on empirical data. The models being wrong do not change that conclusion.
Private Police can make citizens arrests. This means they can arrest you if they have reasonable reason to believe that a felony was committed. In most states, you can also arrest for a misdemeanors committed directly in your presence.
Off-duty cops sometimes do side jobs as private police. In this case, they have the full authority of real police officers.
None of this seems applicable here, though. There's no law about taking pictures of an open ATM. The most they can do is ask you to leave. Personally, I would have walked away as soon as the rent-a-cop admitted to not being a real police officer. If I got tackled, I'll happily get a lawyer and sue.

GM didn't buy Saturn. It was developed as a GM subsidiary from the start. The Hummer deal also wasn't bad for a while, from a business perspective.

Or just be RAM with a battery backup.
Why? Do you have a hard drive that can even saturate a SATA I bus?

Not all Nader voters needed to feel that way. Only a signficant fraction of the ones in Florida needed to.

I might be risking my geek-card here, but none of the new Star Wars were actually that boring due to all the big-budget CGI/effects.
True enough. OTOH, it doesn't say anything good about the movie when it's more enjoyable by fast-forwarding through 2/3rds of it.

Clarkson is for entertainment. He's not to be cited as an authority on anything besides what Clarkson's opinion is.
If that's the case, why did many of those same people decry the stimulus bill as generational theft?

That's ultimately just rhetoric. There's a very specific set of constitutional steps to take to be in a state of declared war.
