Never attribute to malice that which can be explained by incompetence.

To me, this sounds like a pretty open and shut case of "Hey, I've heard that these 'NoSQL' database thingies are trendy these days. Let's use one of those!"

There's a difference between using fun, exciting new technologies and learning something new while doing that... and doing a project which stays in schedule and budget, is based on technology you already know thoroughly, and on which people's lives can depend (well, indirectly).

Sure it doesn't do what a good logic analyzer does, but it's fast. Current project: trying to get an Ohaus digital scale's RS232 output talking via an FTDI serial-to-usb to my computer. Scope-to-computer works great. Computer-to-scope doesn't work at all. Hook up probes to the TX and RX lines and I can immediately see that something's going from minicom to the Ohaus, and the voltage is roughly what I'd expect. On RS232 that's a serious question, and one that most of the usb logic analyzers I've worked with don't address: is the voltage high enough to trigger something that may be expecting 12 volts?
And I'd like to see what it's actually sending. Hit the trigger button and type something in, and there it is on the screen. Save it, type in something else, overlay them. Hey, the FTDI is stripping off the terminal linefeed! That's good to know, given that the Ohaus absolutely requires CR,LF.
That took me about thirty seconds with a scope. It'd take me longer to start up the USB logic analyzer program and get it set up.

Another advantage, if purchasers care to implement it, is that you can have somewhat intelligent LED lights that dim down to 30% when there's no traffic around, so it's still light, but much lower power, then run back up when traffic is a block away. It doesn't add much to the system cost to add motion detection and communication with nearby lights, particularly since some industrial/commercial LED lights are adding selftest health/failure reporting already.

I work in south Longmont. Where I cross the Boulder Creek, it's usually 3 meters wide and so shallow the rocks on the bottom emerge from the surface of the water. When I was hauling out yesterday after our workplace got an evacuation notice, the creek was a kilometer wide, backed up against the bridge, which is probably 15 meters wide by two meters deep.
Longmont spent eighteen months reworking the Lefthand Creek drainage, deepening it and tearing out all the trees beside it, through the middle of the city. At the time, local citizens were outraged at the expense, writing nasty letters to the newspaper and showing up at city council meetings yelling about what a waste of money it was and how debit spending was the devil. Lefthand filled right up to the top and moved like a freight train, but didn't overtop through much of the town. The place where they stopped the rework, and the creek returns to its shallow, cottonwood-tree-filled drainage, is where it spread out and started flooding basements, according to pictures my friends who live there are sending me. I'm hoping this experience will motivate the city of Boulder to do the same for Boulder Creek. One of my friends lived in a house across from Naropa University, right beside Boulder Creek, that had a big metal sign on the front warning the inhabitants that they lived in a flood zone. That should never happen. That should be parkland, not places where kids live. (She moved, thankfully, because that house had close to two meters of water in the main floor, from pictures I've seen, and I'd hate for her and her two toddlers to still be living there.)

LOL indeed. Fructose is a monosaccharide: http://en.wikipedia.org/wiki/Fructose "Fructose, or fruit sugar, is a simple monosaccharide" just like glucose. They're isomers of each other. Sucrose is a disaccharide, consisting of a glucose and a fructose, 50% of each. http://en.wikipedia.org/wiki/Sucrose "The molecule is a disaccharide composed of the monosaccharides glucose and fructose"
Sheesh.

I think it's the 'lol' that particularly annoys me when people say things that are just flat-out wrong.

The Second Avenue Subway project in New York City was started in 1929. It's expected to be partially open in 2016. http://en.wikipedia.org/wiki/Second_Avenue_Subway
The Great Wall Of China has seen nearly continuous work and improvement over 1500 years.
There are a number of Japanese temples that have periodic maintenance/reconstruction schedules that have been running continuously for 500 years.

Sorry about the delay in replying. Those are some pretty awesome caps for railgun/coilgun/quartershrinker applications. High voltage, high amperage capability. If you decide to play with this, bolt a 1 meg resistor across the cap leads and leave it there all the time that they're not actually installed in working equipment, because this stuff could kill you with a discharge. So, yeah, rated voltage and, if they list it, equivalent series resistance, which is a measure of how quickly it can discharge, and you'd like as small as possible.

A non-inclusive answer is that the energy stored in a capacitor rises with the square of the voltage, so what you want for really high energy density is very high voltage caps. But, along with that, when you discharge them, you're relying on an extremely quick discharge so you get huge amounts of amperage out of them (discharge current = voltage / time) so you also need massive current-carrying capability for the plates and wiring. That means fairly specialized capacitors.
