timujin: I used to work for one of the larger storage companies. We were asked for an estimate to create disaster recovery / business continuity capabilities for a major oil company, at the time they kept everything onsite. They were interested in synchronous data replication, offsite backups, that sort of thing. We told them the price, they declined.

In 2002, I applied for a job at a French reinsurance company, for a job to put a digital assets management in place. They wanted to implement this system, because their American branch was located in the World Trade center, and they lost ALL their documents pertaining to their American business.
The interview process was cut short, because a new CEO arrived, and his first order was to stop all recruitment, and cancel new projects.
So, basically, disaster recovery is always a great priority for companies, until they see the price tag. Even when they personnally experienced disaster.

10 years ago the internet was a different beast.

Nah some places still don't understand these things. Try running a maneuver out of the Buchanan County's law enforcement playbook. 2 months ago one of their systems started failing and affected a number of backups. They didn't fix it and lost their data last week so they are back to using paper records.

Just like cell phone and other signals jammers. I'd love to have one for my car since it would knock out everyone's cellphone around me but at the same time they are illegal.

Mmm, loved that show when I was in middle school. Watched it again in high school and thought it was terrible.
Still have that crush on her though (and Sin City was great).
Oh, and emp grenades for US soldiers isn't a bad idea (assuming they work right) it's just progression. As stated above it'll be useful against skynet and more realistic foes.

I've thought about building one just for movies in a theater. I have not researched this at all so what are the chances I'd be caught using one?

Why, Gomer, that's not my hardened command and control network!

Well, surprise, surprise, surprise, Lou-ann, that's not my little HPM!

It is highly unlikely that anyone around you is going to know that it is you that is creating the dead spot unless one of your buddies that is in on it decides to out you. The FCC created a Jammer Tip Line to have a place to report sellers or users of jamming devices. If you end up doing it then do not purchase it from a company, the FCC started going after sellers last month and they have to give the information of people that purchased devices from them since jammers are contraband.

Jammers are a horrible thing. As someone who is on-call on the weekends, if I don't get a message/call to come in then someone could die or become disabled for life.

/don't jam, call assholes out, or report them to the theatre.

doglover: 10 years ago the internet was a different beast.

It doesn't matter. Any decent company would have already been doing offsite backups way before that. Data replication? Yes, that too, if the data was critical enough.

That's a good point. I'm not planning on jamming anyone, I was just curious. It'd be cool to be able to let through "official" channels though.

In that sense, and to cover all on call personnel, I understand the necessity for the phone. (I've been there myself) Aside from it being illegal this is the main reason why I won't do it. On the other hand, I've been hit by 2 cars in the last 5 months because of people farking around on cell phones. I was hit last year by another person (not sure if he was on the phone or not but his story didn't make sense.) He said his tools dropped and he tried to pick them up, note that he had a passenger in the company truck that would have been perfectly capable of doing this task. Nope, he slammed it to me at 40+ while I was sitting at a red light.

As stupid as it is to text and drive, jamming a movie theater has nothing to do with it. I also think that driving around with a jammer would be bad news.

Shadow Blasko: I love Top Gear more than pretty much anyone should I have every episode and have watched most of them at least 3 times

Whilst Clarkson is a complete ass (at least that is the stage persona) he does make good and valid points as far as EV's go. We're being sold them on the false notion that an EV can outright replace an IC engined car. It can't. It won't do 300+ miles 'to the tank', it won't take 5min to 'fill back up' and any EV that is capable of behaving like an IC car costs substantially more than the IC powered version if it even exists.

Can an EV be used for the average commute? Yes. But it would require roll-on roll-off trains to carry them the bulk of the journey, leaving the EV to deal with getting you to/from your nearest train station and the final hump to work.

I have yet to even hear about government proposals to instigate this (and look at allocating the funding needed to overhaul the multitude of stations to accommodate).

So yeah, an EMP grenade and its requirement for energy could lead to interesting things for EV's in the future.

EVs suck now, but the point made upthread was a pretty clear one. The military industrial complex drives innovation, and that usually bleeds into the private sector. You all can't be too stupid to have not understood that.

Cool.

Vaneshi: Can an EV be used for the average commute? Yes. But it would require roll-on roll-off trains to carry them the bulk of the journey, leaving the EV to deal with getting you to/from your nearest train station and the final hump to work.

Where do you live that an "average commute" exceeds 300 miles?

According to the Department of Transportation, 35-54 males drive the most every year: 18,858 miles, on average for 2000 (I'm sure the numbers have changed a little since then, but let's just go with that for now). For the sake of the exercise, let's say they drive the same distance every day of the year. That means they drive roughly 52 miles per day, well within the range of electric cars.

Are there edge cases where electric cars aren't suitable? Certainly. Are electric cars adequate for all purposes and in all situations? No, not at all. However, for the bulk of driving is well within the range of current electric vehicles and their use for common, everyday driving like commuting would significantly reduce fossil fuel consumption and pollution.

If they say they want them they probably already have them.

Noooo, my precious uptime!

calufrax: Cool.

There go your GPS, night vision gear, communications...

Depending on whether or not if they found a "new" method to damage electronics, chances are that alot of existing military equipment is already shielded against EMP. Any army that plans to fight after the nukes drop would have installed basic countermeasures.

I'd imagine this kind of thing is for shorting civilian networks and power grids.

Take for example the attack in Mumbai. Civilians and news reporters were inadvertently tweeting critical information to the terrorists handlers, helping them to prepare for when the counter terrorism units attacked.
Hindsight being 20/20, If I was on the black cats team and had this kind of weapon then I'd have dropped one right by the hotel.

My equipment would survive, everyone elses malfunctions, leaving my men with the advantage.

gaslight: Setting off all sorts of bombs, including your own, electrocution, frying all electronics in the field of effect, including ones you don't want fried like civilian infrastructure, cars telephones, insulin pumps and pacemakers.

And the question I came to ask is answered in the very Boobies. (sniff) I love FARK so much.

heypete: That means they drive roughly 52 miles per day, well within the range of electric cars.

And that's bollocks for a start. 52 miles one way and I might start believing those figures were even remotely accurate.

You need to do 100+ miles with only a 6 - 7 hour recharge cycle from a 30amp unit. Factor in running the radio, headlights and heater as well. Once home it gets another 6 - 7 hours of recharge from anything from a 13amp to 30amp unit.

I'm sorry no. Your EV won't make it to the end of the week as at no point other than the weekends is it theoretically left standing long enough to fully recharge. Friday night you'll be walking 60 odd miles down the motorway.

Ohh and that'd not the DoT, that's the US highways commission and nothing to do with it. Yanks have different city layouts so your point is utterly invalid.

Vaneshi: And that's bollocks for a start. 52 miles one way and I might start believing those figures were even remotely accurate.

Wait, you think the average American drives further than 52 miles each way for their commute?

I'm sorry, but the census disagrees: "Mean travel time to work (minutes). 25.1 +/- 0.1". Only about 15% of people commute more than 45 minutes each way.

If we use your numbers and say that someone only commutes to work 300 days a year (two months vacation, not bad) and only uses their car for commuting and for no other purpose that means they put on 104 miles each day for a total of 31,200 miles per year...which is more than double the Edmunds True Cost of Ownership baseline.

Your numbers seem way off.

You need to do 100+ miles with only a 6 - 7 hour recharge cycle from a 30amp unit. Factor in running the radio, headlights and heater as well. Once home it gets another 6 - 7 hours of recharge from anything from a 13amp to 30amp unit.

Uh-huh...and the source for your numbers are what, exactly?

Even so, the Nissan Leaf can fully charge in about 7.5 hours on a 230V/15A circuit and has a range of about 100 miles. You'd easily be able to do an average round-trip commute without needing to charge and still only have about 50% charge. Charging it overnight or during the workday at one's employer would keep it fully topped off.

Ohh and that'd not the DoT, that's the US highways commission and nothing to do with it. Yanks have different city layouts so your point is utterly invalid.

lolwut.

Perhaps you missed the little bit at the bottom that said "United States Department of Transportation - Federal Highway Administration", or the fact that it's under the dot.gov domain? I think that's what one would call an "authoritative source". If you've got different numbers from some other authoritative source I'd be interested in seeing them.

I'm not really sure what your point about "yanks" having "different city layouts" is or why it makes my point invalid. I'm an American, I've commuted to work for years. While I know that the plural of "anecdote" is not "data", the census and DoT numbers seem to jive with personal experience. I now live in Switzerland and take the train (which is nice) but that's not really important.

I'll trust them on just about anything review wise... but not on electrics.

/Oh, and Jezza's review of the RX-8 pissed me off too. Talks about how great it is and best car of the year and blah blah.. then he melts the damned tires on it, and proceeds to drive it home in the rain and complains that it's squirrelly in the rain. Well.. DUH. You burned off the damned treads making the film.

i enjoyed the episode where James May drove the hydrogen Honda in California. Solid info that left me asking why we don't invest more in hydrogen. I've been told since - here on fark - that the asplody nature of hydrogen is not good

the fuel mileage test of a Prius vs. M3 was pretty interesting. granted, a Prius wasn't really designed for that kind of driving, but still remarkable to say that an M3 is more fuel efficient than a PrIIIIIIIIIus.

There is another option to side-step charging time. Imagine a gas station that replaces your car's power source. If the car is designed for it and we can get our power source (battery is a loaded word) standardized, it could work. You'll have to decide how many power sources to stock, and there are other logistical concerns, but I can't see any impossibilities in it.

Closest to that seems to be BBQ propane tanks. But the batteries are significantly more expensive. People will abuse them and someone else will be stuck with the crappy one.
