I believe the prismatic NiMH cells like the ones used the Prius are patented and are difficult to license for pure EVs. However, there's nothing stopping you from building a battery pack out of NiMH D-cells. They cost 8 bucks each before the volume discount, and you get something like 9Ah at 1.2v. You lose some packaging efficiency with the round cells, but even Tesla builds their battery pack out of round 18650 Li-Ion cells.
Sure, there's plenty of ways to bank cheap off-peak electricity if you're clever about it. There's a system for commercial buildings to make ice at night in an insulated tank that's used for AC during the day.
Yeah, it's fixed with the latest driver, but they had to disable most of the TCP offloading. I had the same problem on my NF4 board. I chucked the NV Active Armor firewall software and never had a problem since.
Yeah, my old school E6300 is an overclocking champ too. It's stable at 3.1 GHz and 1.265v Vcore, less than the stock 1.3v. It can fold all day long at that speed, or if it idles with Speedstep enabled it barely uses more power than stock.
I believe they mean forced (non-consensual) sodomy. Yes, I know consensual sodomy is a crime in a few states too (can't remember if misdemeanor or felony).
It works like this: voting against any knee-jerk "tough on crime" law earns you nothing but attack ads from prison contracters and prison guard unions, or more likely their lobbyist proxies. Hey, I'm all for getting dangerous criminals off the streets, but prison sentencing has far surpassed any semblance of reasoned public policy to knee-jerk stage. Three strikes for non-violent felonies is stupid.
You and I may understand software and Open Source, but to a non-technical voter that's still saying "trust me". People understand paper ballots and physical security.
You could use a computer to print out a paper ballot that's the official ballot of record, but then it just becomes a $3000 pen, not exactly a wise use of taxpayer money even when you count printing costs.
I know what you're getting at. There's more resiliency when there's slack in the system, but it doesn't work that way in transportation. Think of it more as putting your eggs in one basket, like with the Irish potato famine. Doesn't matter how long you can survive on fat if your mono-culture of food just ran out.
Even cheaper than that. I got a spare ipod mini battery off ebay for 6 bucks. The build quality was a bit questionable, though. Hope it doesn't explode.
Sure, it's possible with steady hands and practice. Having taken apart a few ipod minis, I can tell you it's a delicate operation. Read some ipod repair forums and you'll see lots of stories of botched, ham-fisted repair/battery replacement attempts.
I wouldn't say US food prices are just inching up. Same loaf of bread jumped from $2 to $2.60. That's a huge percentage increase, but the 60 cents won't break my budget.
Ok, for the sake of arguement, lets keep the stroke consistent
That's not a fair assumption. It's more common to keep the same bore to stroke ratio instead of keeping the same stroke. High-revving high performance engines have high bore to stroke ratios (called oversquare). Economy car engines are closer to square, 1:1. The Honda Insight had a slightly undersquare engine at 72mm bore, 81.5mm stroke.
Let's assume a square ratio to keep it easy. A 331cc cylinder has 75mm bore and stroke and a 235.6mm circumference. A 247cc cylinder has a 68mm bore and stroke and a 213.6mm circumference.
235.6 x 3 = 706.9 mm 213.6 x 4 = 854.5 mm
I will give you that internal friction is much less important for low-revving economy cars than for high-revving race engines, but it's definitely something designers care about. Just look at the new engines using thin energy saving oils as low as 0W20.
There's a different reason why having fewer cylinders is more efficient: internal friction. For a given displacement, a 3 cylinder engine has less piston circumference than a 4 cylinder engine. It also has fewer crank and valvetrain bearings.
Your analogy breaks down because the body (being the transportation system) can't burn the fat (meaning gas guzzlers, excess cars, and McMansions in the sticks) for fuel.
US motor gasoline consumption is 388 million gallons per day. Ethanol only has 2/3 the energy of gasoline by volume, so you'll need 588 million gallons of ethanol per day to replace it. Even assuming we built enough reactors and the bacteria work fast enough, do you have any idea how much organic waste we have to rustle up to make 588 million gallons? Americans just drive a lot and buy a lot of gasoline. It can't go on forever.
That's the approval rating for all of Congress. We can debate all day the reasons for that, but the right and left both have reasons for hating Congress. The approval ratings of individual members of Congress are much higher, mostly because they bring the pork back and because of safe gerrymandered districts.
I'm not sure standard code libs would help. If it's a good enough knockoff, you should be able to install Cisco firmware you download off their support website, thus wiping any backdoored Chinese firmware. If it's backdoored real well, it'll probably have some special boot loader and extra flash space that could subvert any trusted code you have in the system image.
Even if people buy new motherboards every 2 years, how long did it take to switch system buses? How many have we had since ISA? I'll be generous and count Mac and server buses.
ISA, EISA, Nubus, VLB, PCI, PCI-X, AGP, PCI Express. Better get cracking on that 20Tbps bus by 2010.

Well considering Slashdot doesn't even have a secure login, we're a long way from that. Most web forums don't use HTTPS logins.

June 30th this year is the cutoff date for new OEM sales, not the EOL of support for Windows XP. That'll be somewhere around 2012.

Six hours of wifi surfing sounds pretty good. That's better than some users get. Like this report of 3 hours total.

The iPod Touch is pretty good feature-wise, but the pitiful battery life surfing on Wifi limits its usefulness as a wireless convergence device.

Sorry, you go through customs with your checked luggage too. If they can't boot it, they might just seize it.
