The amount of rigorous cranking it takes to get a charge makes this generator seem inefficient. Maybe efficiency was sacrificed for portability.
Human legs are much more powerful than arms. some sort of foot-operated device would be more tolerable in terms of effort, but probably not as portable. Piezoelectrics that sit in the soles of shoes are not very intrusive, and could provide power over a long time. I believe this is what the MIT wearables group is using.
Hand power, foot power, wind power, and water power require different gearing ratios in order to operate efficiently. An impressive design would allow this type of switch through some type of transmission (CVT? Pneumatic?), and have linkage adapters to hands, feet, windmill blades, waterwheels, etc. The problem is accomplishing this while maintaining a light weight.

Greene, Gweeds and the like are oversimplifying a very complex situation. First of all, while l0pht was acquired by @stake, they do not direct it. In fact, several l0pht members are no longer with @stake, including the group's founder, and Mudge has been 'away on personal leave' since February.
Yes, I know all of the l0pht guys, many others from @stake, and I know gweeds. I do not trust gweeds' motives in this supposed expose, he seems to have become obsessed with publicity, and destructive rhetoric seems to be the easiest way to achieve it ("fuck up the goons" at last year's defcon for instance).
I'd like to see the so-called documents that gweeds, greene, etc. have -- to ferret out the truth.

humans are so stupid. Time and time again we'll be at the brink of famine because of overpopulation, and some genius will find a way to make life better, feed us all, etc....and then we'll reproduce until the NEXT breaking point. The cycle begins again. Stupidity.
What we need is a massive campaign to wipe out short sightedness. I suggest a reverse lottery: you go to the covenience store, stick your hand in a device that will most likely give you a dollar (or a pack of cigarettes, or a shot of heroin), but there's a one in a 500,000 chance that you will be killed on the spot.
That should help with overpopulation pretty quickly. for only $500,000 per head. But less, really, if you count the damage that the cigarettes do.
Yes, the district federal court is correct and yahoo et al are wrong. A Chain of custody should be required, especially with digital data which can be tampered with without leaving any noticible signs that it was.
Civil Libertiarians should also consider this good: if cops have to show up at the ISP in order to have a search warrant executed, it would certainly make them think twice about doing so.

Geodesic domes are very useful, if designed correctly. Another problem quoted is that the walls are round, while furniture tends to have flat backs. This might be a problem in a small domes, but as the diameter of the dome increases the wall will of course curve less. You shouldn't put your furniture flat against the wall anyhow, I have seen many recommendations of at least 2 inches.
The DomesNorthWest.Com site is a good one. Read it for more info.

Are there 15,000 RPM EIDE drives? I don't think so; the fastest I have seen is 7200 RPM and they are rare. What is the MTBF of the drive? EIDE may be faster at burning out. IBM gives a usage cycle of their drives that indicates they are designed for desktop use, not server use. This is usually reflected in the warrantee periods of the drives. 5 years is standard for SCSI, 2-3 for EIDE.
There's more !/$ on EIDE than SCSI, but the performance and reliability isn't there.
In any case, it's a matter of the appropriate use of technology.

I am an administrator for some IP space assigned but not ever routed. Several years ago, I was wondering where the hell all my bandwidth was going and found a lot of it was for DNS traffic trying to resolve IPs in that space. This was very odd, considering that it wasn't routed. These were at the rate of about 10 per second per IP address, and there were about 80 addresses two servers were querying for, for a total of 1600 requests per second. Now, there was no DNS server running on the host that these requests were going to so they were send port unreachable messages.
Evidently what was going on was this large corporation was using MY IP space internally, but they weren't making their DNS servers authoritative for it, so the DNS servers went to the Internet (and to me) for resolution. Something somewhere was configured wrong and so they retried constantly.
I firewalled these DNS servers out, but not before I composed email to the whois contact at the big corporation telling them to fix this stuff. They ignored me (yes I made sure their SMTP sending host was not blocked). Firewalling didn't fix the problem, only kept my server from sending port unreachable messages. The queries from the big stupid corporation's network were only getting worse. I was getting really pissed off.
So I put up a DNS server up on that host, and made entries for every single IP (I was using bind, which is too stupid to have default responses). And I had fun, with obscene and abusive DNS names for every host, and forward resolution to match (in a silly domain also routed to the same dns server) -- and the highest possible TTL! Problem solved!
The funny thing is that this staid corporation was now seeing all sorts of nasty names on their internal servers...BAH HA HA.
The abuse stopped. Hopefully, someone was fired. Now we know that they will never attack me again in this way: you see, that abusive network belonged to Enron:)
I actually let them off the hook easily. I had, at this point, control over data being returned to servers well firewalled away. Servers that probably had ancient resolvers that had buffer overflows in their DNS resolvers. High level servers that could have been r00ted straight through the firewall.
moral of the story: don't leave dns work to weenies. You may be surprised at the results.

there are such things as 'oversight' and 'not waste the taxpayers money', and 'anappropriate use of governemnt property' laws, which at various times have been construed to mean a variety of things. In most libraries with internet access, downloading pornography is considered 'inappropriate', even if you are not a minor. In my experience, this wasn't a decision of the libraries, but the 'powers that be', in government, after alarmist media reports forced them to take a stand pro-pornography or pro-morality.

This is only one example, of course. In general, use of public property is reduced to the lowest common denominator of "thou shalt not"s.

Instead of screwing around with tin cans, wlan enthusiats would be better off learning real antenna design, and building something appropriate to their situation. In addition to the blind and ignorant 'dB gain' that the slashdot wlan crowd seems to be fixated on, an intelligent consumer would be concerned with the beamwidth, the front/back ration, SWR, and the bandwidth of an 802.11 antenna, and not the oversimplified, crude, and possibly harmful (SWR too high can break radio gear. This may include your 802.11b card) pringles-can type of gear that seems to get a lot of geek press. This doesn't mean that you have to spend hundreds of dollars on a Lucent Orinoco antenna just ot have decent performance, but you do have to do some research into figuring out what you need, and then find a vendor that will provide you that at a reasonable price. guerrilla.net provides provides free plans for an engineered antenna (as opposed to the gross hacks which appear here). Yes it's an omni. Still, you may get better performance, because not so much of the signal is wasted due to poor SWR!

The high speed data over mains, as they are testing in the netherlands, has been shown to create massive disruption to radio services. It would take a real lot of money to bribe (lobby) the FCC/congress to allow this in the US, money which would be hard to raise considering the dismal state of the telecom industry.
The service indicated here seems appropriate for telemetry. I wonder if they have accounted for security in control situations though. It may be too easy for someone to forge a packet. Still, at 300 baud (or what that bps?) its interference problems maybe be far less.
It looks as though it's just another 3G wireless chip. I don't see what the big deal is. This article is devoid of any useful information. Except for Palestinians and other Enemies of Israel.

The truth of the matter is, that it is counter-productive to use these 'pop-science' categories. For instance, what 'world' would South Korea belong in? It's a mixture of a highly advanced industrial economy with holdovers from a feudal agricultural society. It doesn't really fit the model of 'four worlds'.
Several years ago, I was talking about this exact subject with a friends over some beers. And we figured out the REAL meaning of the '4 worlds':
1) colonial powers
2) non-colonial countries
3) until recently, colonies
4) those places about to be colonized
Now, this may not make sense to you, but it was a funny bit of truth to those of us at the table who had the '4 worlds' BS rammed down out throats in school.
