yes im sure your asking, why the hell would i want such a thing? UV kills our LCDS!
simple, its not for a projector.
Im a big aquarium person, and anyone who has ponds, koi, large tanks are probably sick of algae.
If you make a tube with a small wattage pure UV bulb in it, that allows water to pass thru it, all the algea organisms are killed by the light
a simple 8watt uv sterilizer bulb can handle 100 gallons, im lookin to only cook about 30gal...however, the REAL bulbs are about 40$ a peice, last about a year
now if theres a cheaper soloution, i know ill find it here. most reptile/growth bulbs only put out about 8% UV, so that wouldnt work
so yes, i admit, its not video related at all, but theres no where else that someone would know this ansnwer, not even the fish people because they dont have a DIY ethic!
thanks in advance.

but could you cook with it.
Actually, I'm wondering, could one of these UV bulbs be used to steralize eggs without cooking them? (I do alot of cooking, the holidays are coming up, and I want my egg nog to be absolutely safe without spending a fortune on the powdered egg crap)

actually i beleive so, upon further reading last night, i found out that certain dryers used to use 4watt UV bulbs to kill odor and bacteria. The UV radiation kills nearly everything, so , i guess it would in fact work, however you might get some unwanted results aslo...for example, some people say it works so well, it kills the biological filter in aquariums (we have bacteria to kill fish poo ammonia)
lol glad to se emy weird request could help others

Be very very carefull, I have read of accounts where people overdid the UV treatment, and lost all their fish. The UV can become too good at what it does and kill of friendly bacteria which otherwhise keeps the tank healthy.
nordic thats exactly what ive heard
im looking to only treat a 30gal, and my gfs pond which im guessing is about 80gla. Mbates suggested UV LED's, however neither of us have much knowledge on them.
8watts would surely be overkill. I think id be alright with 1 or 2 watts.

FWIW, some surgical instruments are sterilised with UV.
It has to be the right wavelength though, which I don't remember at the moment🙄 - a search would turn it up - so I don't think LEDs would work.

used one of these
About 20 years ago I made my own UV EPROM eraser, using a small non-coated fluorescent lamp and ballast. It was a straight tube about 6 inches long, with perfectly clear glass. Inside, it was just like a standard fluorescent tube, but with no "fluor" coating material. The mercury vapor arc puts out lots of UV.
I don't recall it costing much, but it took a few calls to specialty light bulb stores. It used a standard fluorescent ballast and starter for that wattage. Maybe 6 Watts?
I think it might be difficult to sterilize eggnog with it: It would not penetrate very deep. For that you would need a gamma or X-ray source, like they use commercially. Or just use a sterile starting product like Egg Beaters.

Ah well, the whole egg sterilization was a bit crazy anyways. I'll probably go with my normal method of just boiling the nog after it's made. (Have to make it a couple days ahead of time of course so it can get nice and cold) As to the egg beaters, just too blasted expensive compared to the real thing. (I make alot of nog during the holidays. Made several gallons last year.)
Use certified vegeterian fed hen eggs. the whole dangerous egg thing is relatively new and somewhat limited to the US from what I've heard. Many think it's related to the feed, and of course the conditions. When I was in ireland I noticed they don't even refridgerate eggs there. They are on the shelf with the dry goods.
parasites in eggs
I helped my wife study for her DVM board exams, so I read a bit about this. The most dangerous eggs are from "free-range" chickens, because they are in contact with the ground. That's how they pick up the common chicken parasites, and those parasites can end up inside normal un-cracked eggs.
The chickens may not be very happy living in modern "egg factory" cages, but their eggs are much cleaner than the "natural" counterparts. I wonder how they can make vegetarian chicken feed: Most of a chicken's natural diet is insects, which are very high in protein.

a vegeterian chicken feed is one that doesn't contain other chickens, cows, fish, or animals in general. i'm not saying your wrong guy, but it seems strange to me that if freeranging chickens are dangerous that this problem came about in the era of the factory farm.
misunderstanding
When I used the word "dangerous", I meant it only in the context of eating (or drinking) their eggs raw (as per this thread's topic): That has always carried some risk (back into pre-history!). Egg production methods that get the chickens up off the dirt (and poop) greatly decrease their exposure to parasites. But even so, I try real hard not to eat raw eggs from any source. And I would not worry at all about eating free-range eggs or meat, as long as they are cooked.
I wonder if the "vegetarian" chicken feed actually uses insect protein. Even if it doesn't, free-range chickens will supplement it with lots of bugs. That is practically all they ever do, given the choice! I agree that feeding any animal it's own species (or even anything remotely close) is just asking for trouble (like Mad Cow).

I do a lot of cooking, and I have been using raw/semi-cooked free range eggs for about 10-15 years. Never had any problems...
eggs-actly
This is a great disconnect between cooks and food safety people. Cooks love raw eggs because they are so useful in so many dishes. Food safety people all warn about the fact that salmonella bacteria are often found inside intact fresh eggs, be they "factory" eggs, organic eggs, or free-range eggs.
Anybody interested can just type "raw eggs" and "food safety" into google. I just got 38,200 hits, and they all say pretty much the same thing: Cook them!
But free ranging your chickens is a whole different issue: If I had some chickens, I would let them walk around in the garden to eat the bugs, as a humane act. Their brains are hard-wired for this!

I've found you can tell some level of quality from the thickness of the shell. when I get eggs with an unusually weak/thin shell, i avoid that brand of eggs. on a positive note, i read several months ago that researchers at purdue university have developed a method of sanitizing intact fresh eggs w/o cooking them. i don't remember the details. I have never gotten sick from an egg that i know of. i've even eaten partially rotten eggs, accidentally, on several occasions. i eat cookie dough when making cookies, hollandaise sauce, and egg nog. there must be some risk, but it certainly isn't siomething you hear about everyday.
