From The New York Times - a nice overview of the long term benefits
of exercise:
Build a roller-coaster that:
* Is based on the ups and downs, twists and turns of major stories
(e.g., the Wizard of Oz or Lord of the Rings)
* Is based on the DOW. Late 2009 would be fun, I bet =]

This is the best clip art site I've ever found! Lots of public domain images of really cool stuff like:

From the article: "Our system can run nearly perpetually if periodically exposed to reasonable lighting conditions, even indoors," said David Blaauw, an electrical and computer engineering professor. "Its only limiting factor is battery wear-out, but the battery would last many years."

That's cool! The Arm Cortex-M3 is a very standard microcontroller - it supports USB! Article doesn't say what the battery chemistry is... shame the device is limited to the lifespan of a battery (I don't imagine the battery is replaceable) but that's hard to avoid! This is really cool idea and achievement.

Tonight I replaced the batteries in the power brick. The old ones were over two years old, and I hadn't really tended them properly. I'm going to try and recondition them for use, but inside the brick (Xantrex xPower 1500) went three new 18Ah SLA batteries.
The Xantrex opened up really easy - lots of screws, so I wanted to use the drill - but the screws are hard up against the case wall. I could have gotten them with a regular screwdriver, but with 20+ screws to do I decided to drop $7 on an extension from OSH. This is basically a rigid spring that gives the drill the reach of a normal screwdriver.
Inside was three 17Ah SLA batteries robustly wired in parallel, the inverter, and some foam to stop the batteries moving too much. Also two panels - the main one with AC outlets and switches and the "battery test" LEDs, and another with just a car-style DC jack.
At first the bank didn't want to take a charge, the AC charger went straight to green light (which I guess is triggered by bank voltage?). Voltage was below 13 so I'm not sure what was going on... can't believe they were fully charged coming off the shelf. It was pretty cold outside which maybe changes things. Ah, I don't know. Load tester was unavailable (long story), so I ran a lamp for an hour to discharge the bank a little. After that the bank started taking a charge.
The other weird thing is that the "battery test" meter has stopped working. It's just a rocker switch and a bank of LEDs, but now the LEDs don't light up. Not helping. I'll have to check it out... in theory I should be able to fix it, in practice I tend to screw these things up =]
Premise: "Corporations can cause harm" Premise: "Corporations shouldn't cause harm" + Milton Friedman + Deregulation Advocacy = DOES NOT COMPUTE.
Right?
If we agree that corporations can harm, but shouldn't, then it follows that a corporation's actions must be regulated somehow. The primary options are self-regulation (to avoid doing harm, a corporation voluntarily forgoes a profitable activity) and external regulation (there are rules, enforced by the state, that limit or prohibit some kinds of profitable activity). If, as Friedman argues, CEOs should abstain from self-regulation, then external regulation is required if harm is to be avoided.
I suppose in reality, we have both - there is some self-control from even the worst CEO (there are no too many massacres), and there is plenty of regulation. I suppose those that advocate simultaneously for deregulation and market freedom would agree with the principle here, but take issue with the amount and nature of the external regulations.
Hmmm.

Nice slashdot comment on battery tech:
http://hardware.slashdot.org/story/10/01/27/2318247/Lithium-Air-Batteries-Get-Boost-From-IBM-and-DOE?art_pos=3
Lithium-air is, IMHO, one of the least promising upcoming battery techs. It's really more like a fuel cell, and to be blunt, fuel cells suck. By that, I mean:
* Expensive per watt
* Short lifespans
* Inefficient
There are many, many promising next-gen battery techs other than li-air. Here's just a couple of my favorites.
Lithium-sulfur: This has long been worked on, but only just recently one of its big problems has been worked around. It offers great energy density, but some of the intermediary reaction products -- various lithium polysulfides -- are rather soluble. They'd migrate across the membrane and precipitate out on the other side, being rendered permanently useless to the reaction and thus aging the cells very quickly. Older solutions to try to prevent this caused dramatically lower energy density. The latest technique involves wicking the sulfur into the pores of mesoporous carbon and then functionalizing the outside of the carbon with polyethylene glycol to keep the hydrophobic polysulfides inside when they form. The longevity improvements were amazing, without sacrificing energy density. We're talking that when they deliberately chose a worst-case solvent, one that's really good at dissolving polysulfides, the traditional Li-S cell lost 96% of its sulfur in 30 cycles while theirs only lost 25%.
Nickel-lithium: It is, quite literally, a hybrid NiMH/li-ion battery -- a traditional NiMH cathode that can hold a tremendous amount of lithium, and a lithium metal anode (almost obscene anode energy density). That's normally impossible, since you want to run a NiMH battery with an aqueous electrolyte and your various lithium-based cells with an organic electrolyte. They do both -- they use a new tech called a LISICON membrane to keep the two different electrolytes apart but allow lithium ions across. An additional problem with li metal anodes is that dendrites tend to form that rupture the membrane -- but LISICON membranes are a rigid ceramic that resists dendrite damage.
Digital quantum battery: This is my favorite, because it comes straight out of left field. It's really a type of capacitor. Now, capacitors normally hold a lot less energy than batteries; if the voltage gets too high, you get dielectric breakdown, it arcs across, and your energy is lost. But at very tiny scales, current must move as quanta. So if instead of a single big capacitor, you lithographically print an array of nanoscale capacitors, all of the sudden you can make it so that you essentially can't get dielectric breakdown. In fact, you can store so much energy that the stresses become so great that it's best to use a carbon nanotube for one of the electrodes in each nano-capacitor. :)
And even ignoring next-gen battery techs, there is still *huge* range for improvement in li-ion. In particular, for the cathodes, my favorites are layered manganese cathodes which alternate long-life forms and high energy density forms of magnanese oxides to get both properties; and fluorinated metal cathodes. For the anodes, there's many kinds of tin and particularly silicon anodes out there that store nearly an order of magnitude more lithium than conventional graphite anodes. Silicon anode li-ion cells are just this month starting to hit the market. The tech has finally matured to the point where their longevity is sufficient.
