The Grid, Our Cars, and the Net
Wired is running a piece on the big idea of Robin Chase — the founder of Zipcar — that we need to build our smart power grid on open standards and include cars as nodes in a mesh network. "'Today in Iraq and Afghanistan, soldiers and tanks and airplanes are running around using mesh networks,' said Chase. 'It works, it's secure, it's robust. If a node or device disappears, the network just reroutes the data.' And, perhaps most important, it's in motion. ... Build a smart electrical grid that uses Internet protocols and puts a mesh network device in every structure that has an electric meter. Sweep out the half dozen networks in our cars and replace them with an open, Internet-based platform. Add a mesh router. A nationwide mesh cloud will form, linking vehicles that can connect with one another and with the rest of the network. It's cooperative gain gone national, gone mobile, gone open."
Big ISPs and phone companies have too much to lose to allow this to ever happen.
It would be too hard to be tapped by various 3 letter government agencies so they wouldn't like it either.
Maybe instead of continuing to focus on the dinosaur that is the automobile, more effort should be put into building very a efficient mass transit infrastructure. Just a thought.
Hi there
What we need is to have it integrated into our phones and that we can tether to so:
a) consumers choose phones with over phones without
b) we can use it even outside the car and
c) it's not connected to cars (better to stop the car rebellion right there, tyvm).
I vote thanks but no thanks on this. Despite whatever wild-eyed claims about "openness" or "oneness" or whatever other hippie bullshit the brainchilds of this are spouting, there is absolutely NO information of any kind that is appropriate for my vehicle to be broadcasting. I'm sure the police and Federal government would absolutely LOVE to have a way to track the location of every vehicle in the country, not to mention who owns it and who they're talking to via their built in net cellphone at the time. Integrating this with the idea of a vehicle is a hilariously bad idea, because the instant it comes about there will be DOT, Federal, and State laws with a laundry list of mandates about how "open" this system will be allowed to be to be "roadworthy," and I guarantee you not a single one of these mandates will be in your best interest.
Pass.
If we're going to do the mesh network thing, I'd rather have it in a portable device like a phone or PDA that doesn't give the government a billion inroads to regulate, legislate, and subvert it, and one that I can chose not to buy, to turn off, or to leave at home.
I can't say I completely understand the article. It seems either she, or the person who wrote the article, is confusing mesh networking with power distribution. The article doesn't make clear how the two fit together (maybe someone else who understood can explain better). It talks about wireless networking at the same time it talks about plugging things in. Those two don't seem to fit well together (yeah, I know, some companies are developing wireless electric device chargers, but it's a totally different concept).
One thing that interested me in the article was this quote, " the Obama Administration allocated $4.5 billion in the stimulus bill for smart grid R&D." So we're getting some kind of smarter grid anyway, at least some research into it.
Qxe4
... will plugging my car into this "mesh" gain me? I don't see a reason for this. It's excessive and prone to more problems than we already have (I guess. I don't even understand exactly what problem she's trying to solve so as to properly determine that). I don't see the automobile in the same light that she does. Just let my car be a car and be powered by my power, Mrs. Xzibit.
The eternal struggle of good vs. evil begins within one's self.
My point isn't that mass transit should be ignored, or that we shouldn't look at doing it in a more effective way where it makes sense, but that wide scale mass transit that has as a stated goal of replacing the automobile in most circumstances, even in rural America, would not be advisable. There are about 303 people per square mile in France (non-euro territories not included), compared to 33 people per square mile in the US (excluding Alaska's area). I've excluded the no-mans-land of Alaska from this equation, but even if you excluded all of the areas where nobody lives in America, you'd still have a significant density difference between France and the US. The issue is not the same here as it is there by a large margin.
The other things is, I was in Pittsburgh in the early 90's during the Port Authority strike - no busses or trains ran in Pittsburgh for a week or more. What I recall is that people found ways to get wherever they needed to go, the air was SIGNIFICANTLY clearer and cleaner without all of the diesel belching busses on the road, and even though everyone had to get to work by private vehicle, traffic moved BETTER, because the slow-assed busses weren't clogging traffic up at every intersection in the city during rush hour.
Hello? Sorry, I'm going to be late for work. I'm trying to get out of my driveway, but the car just says "Buffering..."

I did a lot of tariff programming back in the day and I loved it...
Electrical demand is not the same as network demand. If your ISP is short on bandwidth, everyone just slows down. But if your power company is short on power, at worst, they have to start throwing people off of the grid, because everyone must have 110VAC 60hz power.
This reality is reflected in the pricing of electricity, especially for larger customers.
The kind of an electric bill a refinery gets, for example, shows this. In such bills, you start with the raw data obtained from power recorders - every kwh and kvarh (reactive power), is recorded at either 15 minute or hourly increments, depending on the utility. This data is rolled up to look at peak demand, and bill to date usage, broken out into buckets representing time of use, each of which has its own price. For the most part, the demand portion of the bill is roughly half, and the other half is the cumulative portion.
So, of all the actionable items in a bill that one could act on, really, instantaneous demand is the most important thing to optimize. If you jack up your demand during the day, for just one hour, by 50%, you've significantly increased your monthly bill... because the utility still has to have equipment to satisfy peak service.
The thing is, industrial customers have known this now for at least 10 years, if not longer, and there's a whole electrical services industry designed to help them avoid that maximum demand charge. Some companies making ice at night for cooling by day. Others try and have multiple shifts. Still others just put in their own local generation that kicks in when their utility usage gets too high. All of this is controlled by automated SCADA systems that have been field proven for at least a decade, if not longer.
The point is, I'm wondering how much smarter the electrical world can actually get? What you are really talking about is putting residential customers on industrial style tariffs. But, what would be the benefit? I mean, there's not too much a residential customer could practically do that would cost effectively help them lower their peak demand in such a way as to be cost effective.
For example, in California, for SCE, the GS-2 tariff specifies a demand charge of less than $10 / kw. SCE GS2. If you figure that most homes use less than 2Kw max demand, there's not much room for economical demand shaving. If you lowered your peak demand from 3kw to 2kw, you would be saving $120 a year. There's few, if any devices that could store energy at night, help with peak demand by day, where you could actually recoup that investment economically.
This is my sig.
I hate to break it to you, but this far everything everyone's ever penned on this particular subject because... are you following along with this at home? The technology doesn't exist yet. We don't know. It's an unknown, and anything could happen up to and including nothing at all.
All I'm doing is putting forth a possibility tainted by my own opinion. I'm straightforward enough to be honest about that. Why are you so hell bent on turning speculative opinion into some kind of bullshit personal affront?
While we're on that topic, though, let's look at the track record of our illustrious elected officials. It is already mandated that all cell phones sold in the US come with GPS chipsets capable of transmitting your phone's location. In most cases this can be disabled excepting 911 calls, but the technology is there. Your position can already be triangulated fairly accurately just via cell towers. This is a proven fact. Warrantless wiretapping and general spying on US citizens without cause by the Federal government is so well documented that there's already been massive outcry and a million and one headlines about it. This is a proven fact. OBD2 compliant automobiles sold in the USA are required by the DOT to have black boxes (for lack of a better term) that record vehicle speed, brake status, RPM's, and the other assortment of telemetry available in a modern engine for the sole purpose of the police using it against you in post-crash investigations. This is a proven fact. Traffic cameras are already in place in many locations throughout the country and are not only used to hand out speeding tickets as well as track individual vehicle movement when the police so desire, as has made headlines more than once. This is a proven fact.
None of the above is speculation. People who live off your tax dollars want to know where you are and what you're doing at all times, and the demonstration of this desire is made clear again and again and again. How many stories are posted to Slashdot to the effect of "company developing X technology to recognize faces/scan fingerprints/track crowd movements/snoop on cell or internet conversations?" Count them. How many of them go on to say they're doing it with government funding or for homeland security purposes, and all those other buzzwords? There's a reason Slashdot has a "Your Rights Online" section. There's a reason stories like these are of so much interest.
What is speculation is what will happen if a widespread vehicle based network of no concrete design or aim is put into service. My speculation is that bad things will happen if it is, especially given the track record of the US government both Federal and local in passing mandates involving automotive technology. If you don't agree with my speculation, that's fine. But if you want to blow it out of proportion and turn it into some kind of affront that's all you.
