Yeah, I was quite shocked to see this. Even more shocked to see that he has patents for it. I worked on a vawt for awhile. There are about a 1000 different variations online by diy'ers. Savonius originally patented something that looks essentially identical to this device in the 20s! From my experience its great in areas where you have a low constant wind. Tip speed sucks, but you can get more torque with this device. It works great in an area with lots of flat like where I live (Indiana). I believe it was originally designed to be used to grind grain on farms.
More importantly you pointed out that the BBC Science Correspondant is in fact bad at math. A gain in life span from 2 to 3 years is a 50% gain, not a 30% gain.
speaking of robotics, anyone know where i can get something that operates like an on/off 180 degree electronic actuator at the cheapest possible price?
I say like because if a dc motor with stops, a stepper motor, or a servo is the cheapest I'll do it. I'd preferably like the easiest/cheapest rig I can do for
Thanks.
1) Oh! I didn't realize the definition of audiophile was one who makes absurd pseudo-scientific claims to show how knowledgeable they are about their obsession. These visuophiles would certainly use high purity glass for frames, high resolution for tv's, and probably wouldn't print pictures on a decade old epson inkjet. Audiophiles in my mind (as an engineer) are people who use their engineering knowledge to improve the quality of their sound. Most stereos are so incredibly bad their is absolutely no way they give the impression of a live performance. However you can improve that and approach quality sound. You certainly wouldn't find an art lover (visuophile?) making prints on his cheap inkjet printer on 8.5x11's and then gluing those to his walls. He'd probably take steps to improve the quality of the prints.
As for the comments about lies and pretentiousness, is improved filtering on a power supply or reduction of clock jitter in the name of improving a subjective experience pretentious? Most geeks go to great lengths to perfect technologies, but as soon as its something subjective it's not cool enough for the/. crowd. Go to a local hifi shop (if there are any near you), take some of your favorite CDs, and just sit and listen for a while. If the sound is better than what you find at best buy, there must have been a series of minor modifications to get there. A true geek would want to find out how he can do it!
1) For something as subjective as viewing paintings and sculpture, I find it interesting that everyone here is trying to bash people for trying to increase the quality of sound in their stereo. One reason may just be a generational problem where modifications were much more apparent in equipment 30-50 years ago.
2) I also find it funny that everyone is bashing the audiophiles when only a few stories below is about a guy who memorized >80k digits of PI (far less useful than modifiying stereo gear). Just so you know how relevant 80k digits of pi is: "If one were to find the circumference of a circle the size of the known universe, requiring that the circumference be accurate to within the radius of one proton only 39 decimal places of Pi would be necessary."
I disagree, I've been of the belief to replace the equipment earlier in chain otherwise you're just amplifying/modifying the problem. First is the inputs like mics, etc. Then modify the source, pre, amp, then speakers. Most people go straight for modifying speakers or amps. I've found the weakest link is usually in the voltage amplification whether it being in the output stage of the CD player or the pre-amp.
Using the wavelength to describe a color to a blind person wouldn't go very far would it. Its like describing sound in text. Very difficult to relay without using completely unrelated words.
Because the amp probably has terrible voltage amplification. If you do it in the early source components then the amp is primarily dumping current (which cheap solid-state amps do best).
You'd be referring to even order harmonic distortion which is damn tough to add (without much odd order harmonic distortion) without using those expensive tubes. Remember, that "high" distortion you are mocking is the same even order distortion you hear in nature. You're cheap amp from best buy has low distortion, but a load of odd order stuff!
Actually "audiophile nuts" solder it straight! The ones with the overpriced amps and rca jacks are the ones who don't know how to modify or even know why their equipment is better other than the salesman told them so. As for $50 caps I can assure you can hear the difference in power supply caps. As for the others I haven't found any sound difference in anything unless its inline.
go take an equalizer and throw the values at all kinds of levels. congested quickly becomes a decent adjective for what you'll hear at some settings. describing sound is a little like describing color, except you can show color on the internet and in print but you can't do sound without being live and thus you must use goofy words to describe what you hear.
i'm a geek too, but c'mon, value your time.

While I've done some completely pointless projects, I've got to say don't waste your time on this one. Its not like its technically challenging to build your own system. Its not geeky, its still just following pre-written instructions. Buy a damn TiVo and work on something more interesting...
I agree with those that say do both! If you don't want to/can't take both majors, take a program that offers courses on both (ala Computer Engineering). If you go to a school that offers it, and you enjoy both hardware and software I would highly recommend it as you can usually lean your technical electives to areas where you have the most industry and the industry will take into account your well-roundedness of the two disciplines.
Hit the nail on the head. The services are limited (just as Windows [any home edition] should be). Now granted that luxury isn't available for Server 2003, but yes, I was just making the blanket point that I'm more comfortable with an old version of linux than Windows. For pre 2.4 kernels though thats probably somewhat of a security through obscurity.
Is it just me or was the story about 10 stories down about how spyware can disable Microsoft's Antispyware and take your cc #s, passwords, etc. I have been using a copy of linux on one of my exposed servers for several years without patching and without any significant security configuration at boot and it runs like a dream! [Although I like my OpenBSD machines better:-D]

I looked long and hard to select my current watch. I'm quite happy with my find. I wish I had an automatic now, but I still thoroughly enjoy this watch. http://www.russiansouvenirs.com/web/watch/pc225.ht m
Its just too bad you have to live in Canada to get such a good price.

Holy crap! I've been around audio for quite some time. I've seen my fair share of the b.s., but I have yet to have seen expensive knobs! Nice find.

That one is freakin priceless. Whats scary is that I've heard that one!!
