Careful. We want them kept south of the border longer than Americans want... :P

Logically they would go for something around 4%O2/96%N2. SF6 is ozone depleting and controlled by epa even for medium voltage switches.

You can survive with low exertion levels down to around 2.5%; with a non sealed mask an oxygen or even compressed air bottle would be plenty to get you to a comfortable PPO2 at 8,000 feet.

Lol.. i'm not wrong. Trucks pay more than four times as much but more importantly, the amount of taxes collected are enough to cover the maintinence from the combined damages on the roads the trucks drive on. It would likely be enough for all the roads if portions of the money wasn't taken and used for other things.

Fuck you really never have anything intelligent to say do you.

The problem is that if the airframe is moving directly at the White House from, say, New York Ave, it could do so at ten feet above the ground. Would still clear the fence, but anybody on the roof of the White House opening up with any sort of AA or even conventional small arms fire would be, essentially, shooting right at hundreds of people, cars, trucks, and office buildings. NOT an easy problem to solve.

Yes. And drones don't kill people, people kill people. It's actually kinda funny to watch a lot of normally "progressive" types who've always reflexively ridiculed the sport shooting types for their defensive postures regarding irrational gun laws ... suddenly find themselves in exactly the same predicament. "But I just want to do some fine art landscape photography from 50' feet up!" Uh huh, and I just want to break some clay pigeons. But we're BOTH evil now! How's it feel buddy!

Scenario: pop away some sort of cover on a flatbed truck a couple of blocks from the White House. Fire up a very un-sexy, easy to build hexa than can easy lift a few pounds. It could quickly self-navigate straight up to a couple hundred or more feet (these things can climb like rockets), above any local building tops, and then move horizontally towards the White House at the better part of 50mph. Who CARES if it can be detected? If there are people on the White House lawn doing some sort of camera op or press conference, that bird would be right over them in the blink of an eye, and could drop something nasty with shocking accuracy, within a meter of a typical presser podium. It would happen so fast that being detected or not doesn't really matter.

I love these machines. They're great for all sorts of fun and creative uses. But a smart, determined bad guy really could put them to some very evil, if innovative, use. And that's the point. New government limits on their use make the bad guys just laugh!

I have a pimped out Phantom. The extra payload it carries:

1) GCU
2) Gimbal
3) GoPro with Battery
4) Video Downlink TX with cloverleaf antenna
5) iOSD
6) Various related cables, mounting hardware

Which all adds up to almost 340g - and it still maneuvers like crazy, and stays up for an easy 15 minutes.

No, it's not a lot. But it's lot more than low-double-digits. My bigger rig can easily carry 8 or 9 pounds while climbing to hundreds of feet faster than you'd believe. And it can go horizontally at a pretty frightening speed.

What? Lol

This is the opposite result of less regulation. The government was sharing the costs of bringing broadband to rural areas. Now they cannot because a single entity by regulation changed a definition that specifically applies.

2002. They saw what we preached and acted on it. They did it with fiber because of the nature of their governments rather than the utilities.

10-100Mb wasn't uncommon in Sweden then in the cities, although rural may have taken longer.

Do you see how your statement defeatz itself in context?

He did not say only criminals use it, he said criminals love to use it. Also, as long as that is the theme being pushed by the governments (propaganda), his point is still valid as governments and law enforcement are demonizing it and it will make them the enemy.

Try 3M Novec 7200.

How common are datacenter fires? The last time I heard about a computer catching fire was more than 20 years ago, and the fire was minor and didn't spread to adjacent equipment.

I suspect the battery stacks, generator fuel, or high current wiring for delivering electricity would be some points of greatest risk.

Theft is not that common in above ground datacenters, either; the facilities are serious about physical security. It is probably due to the same reason the facility is underground in the first place and why people would like to colocate something underground --- higher security, lower risk tolerance compared to applications for traditional datacenters.

Protection against fire is just another physical security issue being addressed. Without the low-O2.... the risk of damage to equipment by fire would be perceived to be higher in an underground facility with closed and confined spaces than an aboveground facility; less freedom of air to move = potentially greater risk over time of wearing out electrical systems that malfunction and overheat at risk of causing a flame to ignite.

Also, being underground, there would be no easy firefighter access.

Technically SCBA like the fire department uses, unless they use rebreathers.

You are crazy if you think the amount of wear and tear or damage to a road from one truck is 8 million a year. The prius is getting over charged but that doesn't matter.

Now your facts are a bit off too. A tandem axle has a weight limit of 34,000 lbs which effectively reduces your 20,000 to 15,000. and the steer axle is limited to 12,000 lbs. The 20,000 lbs is only if there is ten feet between center line of the axles even if they are rated for 20k or there is only a single axle on the truck besides the steer axle. But we are talking about semis now unless you want to change the goal posts again.

  Also, the prius has single tires per axle side and a semi has dual tires or the equivilant in what is called a super single. Its not a direct comparison but the math works out to the truck paying over 4 times as much as the prius anyways.
