Crystal Eyes and Monochrome monitors. The monochrome monitors were capable of putting out 200+ fL of light (about 4x brighter than your typical out-of-the-box LCD) and the crystal eye shuttered glasses were capable of extinguishing 99+ of the light. The result was a realistic, if slowly refreshed, 3D image.
I've also looked at a number of displays- my favorite so far is the Stereo Planar- still requires polarized glasses but the display is sharp and fast and, when integrated with the 24" NEC IPS panels gives decent motion performance.
There is McNaughtten (Sp?) rear projection LCD displays- I only used the prototype- I wasn't a fan but others have liked it. I believe the fan noise bothered me quite a bit, not to mention some of the speckle. That's being fixed with some new diffuser materials.
Lastly Kodak actually had a 3D display- used two LCDs aligned in a box- you looked through a lense element (no glasses on the face) and saw the projected 3D image. Very high resolution, very bright- but it got canned.
There are good 3D solutions out there (or at least it's getting better). You're probably just not willing to pay the price to get it.
I could see some advantages of streaming both ways to large flat panels. I think it would be a bit intrusive, though, because as much as I love my parents I'm very glad there is a 10 hour distance between us.
If all else fails you could just do a webcast. While interestingly linked, I just can't get into the concept too much for fear that one day I might see my mother in law staring back at us;)
I loved clark connect. Best firewall package out of the box- and you're right, up and running within 30 minutes.
Unfortunately (couldn't you tell) some of the changes they've made are less than stellar. I'm still pissed about how difficult it was to get the new virtual hosts up and running on apache, and I have had to edit all the files by hand.
In addition the user accounts are a pain- I don't know how to log in except as root (or other user) to get full access to the server. Basic user accounts are limited to changing passwords- that wasn't there in the older version.
But for a firewall it does great. I just want to use it as a webserver, order form, multimedia server, etc.
Riiiight. That's why it's taken how many years to get the code released on the breathalyzer? A corporation would stall, stutter, fight just as much as a private individual. In fact most private individuals would cave whereas a corporation would provide lawyer after lawyer while saying it's a trade secret, etc.
I'm surprised that you'd consider a corporation capable of just rolling over and playing dead. Yes the airlines did that for the TSA...
I have a coworker- a very smart, phD, educated individual. We just had an argument with several other smart, phD level individuals joining in about a very simple topic: Water.
Hard water, in fact. He discovered a website that purports to soften water by wrapping several lengths of wire around a copper pipe and applying a secret pulsed 9 volt charge. The effect is to make the hard water appear 'soft' and feel 'soft', without the use of salts and ion-exchange media. The effect is temporary, the site claims, and reverts to the same previous hardness within 24 hours.
Did I mention he's a very smart individual?
His point: "Something happens. My hands don't crack". My point: Just where the hell do you think the ions go? South for the winter?
At this point several of the other brilliant individuals grabbed my hard drive magnets to put on their copper pipes because they'd also heard of 'magnetic softening' and wanted to try it out.
Actually, the moral of the story is to have a neighbor/friend somewhere else where you send them copies of your encrypted data. That way there's nothing that can go wrong.
I've learned: This time I took PHOTOS of all my rebates before they were stuffed in the letter. I like hearing that they didn't receive what they needed because now I can fax them a photo with all the material in it...
One thing that they (wrongly) state is that 16 bit is better than 8 bit. Yes- it shows more grey levels. But it doesn't show more DENSITY levels. That's the problem when people scan various films- film can have a tremendous density range (3.8 or so), and when you capture that much range you get images that look pathetic. They then have to be rendered down to a human-pleasing visual curve- S curve- and then what you see is something nice.
Every scanner on the market scans for an 8 bit 'S-Curve' with more grey levels (10, 12, 14, etc). Most can't/won't give you access to the raw transmission data (density = 1/transmission). I'll have to see if I can't get my old tutorial on the differences, but if you have 12 bit 'raw' density (linear corrected, of course- so greys track grey) then you can use specialized algorithms or dodging and burning to adjust the image, bring shadows up, bring highlights down, restore detail, change localized contrast- THEN YOU RENDER IT to 8 bit (or 10 or 12 bit) with the appropriate human-pleasing S-Curve.
I'm probably not making alot of sense because there are very few people out there that understand fundamentally that every scanner, 8, 10, 12, 14, or 16 bit, is really throwing away a TON of the data on your film... and it's scanning it in such a way that you miss out on all that information, permanently.
The first time NASA scanned a bunch of old chromes they used Kodak's HR-500 scanner. I got in on the end of that, after all the work had been done and (unfortunately for the world) after all the images had been rendered to 8-bit JPG/tiff files.
I'd hope the contacts I put in place could talk to each other and do it right (extended bit depth scanning, custom raw image processing) but since my old group at Kodak has been gutted to 1 person (a supervisor with no direct reports) and the building that housed all the scanning knowledge and equipment is being torn down... I somehow doubt it.
Once again, the world loses out in terms of better images holding more information.
Not that I don't think NASA will do their best- they just didn't have access to the kinds of equipment and the low-level software interface to allow the levels of high precision I'm talking about.
Which matters how if it still takes up 1 m2 of roof space?
Good point. You can't increase insolation. Go higher or use mirrors, but you're stuck with that 1kw to 1.5kw/m2. BUT say you use a concentrator that only utilizes 10sqcm of capture material. You've invested in the land, the mirrors to drive them, the mechanisms... and suddenly they increase solar performance to 50%. You want to upgrade? Replace 10sqcm of material. Everyone else has to replace 1m2 of material.
Seeing as the high efficiency solar cell material was going for about 10$/sqcm... were you to have one full meter of it you'd be looking at a very pretty penny. Smaller upgrade costs for a given fixed infrastructure cost.
Just more food for thought.
(And yes, I completely agree- but there's no easy way of making a 100km tunnel of vacuum;-P )
While at Purdue one of my friends worked on a process to increase solar cell efficiency by etching TiO2 coatings into long, thin whiskers that helped 'whisk' photons down into the surface of the material. It basically doubled the efficiency of a 3% cell in the visible range. Solar hasn't taken off.
Glass typically blocks UV. Most glazings contain glass. If this only boosts (and 60%, while a large number, is still a tiny increment in efficiency) the UV efficiency then there may be limited use... unless you count concentrator applications.
The "Sun Cube" (http://www.treehugger.com/files/2007/04/sun_cube_ by_gre_1.php uses lenses to concentrate light onto small, very efficient space-grade solar panels. Each panel (if memory serves) was on the order of 1 sqcm, allowing these very expensive but very efficient (25%+) panels to be used. The overall effect was to to take 1 m2 down to 10 sqcm of chips.. and yet have the power output be about the same. Combine that concentrator technology with higher utilization of UV bands AND ultra-efficient space grade panels and you've got a winner (concentrators work ONLY in direct sun- no clouds).
How many times and enzyme can be activated is very relevant. The number of 'turn overs' is critical for planning a plant. If an enzyme can snip at the reversed linkage on cellulose only 1000 times before becoming poisoned that means, approximately, 2000 molecules of starch. 200 molecules of starch yields 4000 molecules of ethanol. That's 1:4000, which means a heck of alot of enzyme is going to be needed.
Another place this is very relevant is actually in crude oil cracking. The number of turnovers a catalyst can provide before needing regeneration is critical to the efficiency and profitability of the plant.
(As for sulfuric acid I simply wanted to point out that it's a very destructive, exothermic process)
The only thermo-chemical method of producing alcohol from cellulose that I know of uses concentrated sulfuric acid. If this is what they're doing...
And their explanation of expensive enzymatic reactions? Hogwash. Enzymes work for 1000's of turnovers (at a minimum) before they become poisoned and lose their efficiency. They don't go to ethanol solutions, they go to starch solutions, which then get converted to sugar (think beer), and THEN get converted to ethanol.
That goes into a refluxing column, add a couple of zeolites or corn grits to dry it to 100% Ethanol, and you've got Fuel!
That's the funny thing. He swears he does. Yet somehow I always find porn on the machine.
Now I even covered for him once- claimed all the porn on the machine was due to a virus (to his wife). You know how it goes, protect your own. But he still swears to me he didn't download it. So if it's not him, and it's not her... then what is it? Their stupid chinchillas ? Right...
Anyways, that's how I think they got infected the 3rd time- codec download.
Errr, no, you misunderstand. I get them AFTER they've been infected. Not before. Well, not usually- like my Sister in Law and her constant re-infections. In her defense though, someone got in and a new 0 day virus was updated... aol=updates.exe Kinda interesting to find out you're responsible/included in the next round of antivirus updates.
I do instruct with proper firewalls, etc, but if they don't listen... and they now run nearly a dozen apps to keep the systems clean. Sounds like Over kill to me, but whatever works.
I have been repairing computers for friends/coworkers for some time and Rootkits scare me. I run the MS tools, the blacklight, the A2Free, the hive comparators.... and pray that I'm not missing something. It's either that or re-install their OS, and since they come with DELL OEM licenses before Dell shipped CDs, that's a crapshoot.
The last machine I worked on actually had 'new' virii on them, which went off to AVira and Norton as a 'new' virus and was included in the next days updates. Insane.
My brother in law wants a new computer because he no longer trusts his disk - it's been infected so many times that he figures it's easier to get a new system (I've reimaged it several times to fix the problems). I keep pointing out that it only takes one infection to get ruin the new computer, but he's adamant...
Why can't we just get along...
(and don't tell me to put Ubuntu on peoples laptops...)
The guys that actually did Sept 11? They're dead. That happens when a plane slams into a building/ground/concrete structure.
Oh, you mean the ones that planned the attack? The US is slowly picking them off. They don't stand on a podium and announce their evil plans (like Dr. Evil), they use a dozen cutouts with hand couriered messages and ignore cell phones/wired phones for fear of being killed. It's a pretty good fear, so far.
And I will not defend anything else you say about the administration because it makes me sick. But please give credit where credit is due- the US is going after the people that orchestrated Sept 11th, and will, more likely than not, find them (dead or alive).

It starts to get REALLY hard to get reliable data past then. There was that plague issue... although some records survive, my uncle had quite a few problems getting access to them (travel TO the church to view the registry, etc). Even monetary reimbursement for people on site to look up information is tough.
I don't know why I was modded as funny, as I was very serious- this would be extremely interesting to see. Privacy aside, it's a fascinating concept.
I was pretty interested in the service that would trace your genetic heritage- race, country of origin (or percentage, etc)- it would have been fascinating. My uncle has mapped his side of the family (1/2 mine) back to the 1400's... so this extra step would be incredible to combine with.
Then... there's the privacy aspect. But just because I didn't do anything, yet, doesn't mean....
