The aquarium sterilization sounds very much like my machine coolant setup. I am just using an 18" fluorescent blacklight. I thought that if there was any real interest in this than I might look into something for a PC. As far as the LEDs...there are some pretty powerful laser guys out there and if you pulse the output you can get increased intensity...
I also have a few microwave magnatrons lying around...talk about mutant bacteria!
Thank you guys for all of the great responses
, but I don't want to drop the ball here. I think that there is some promise with this idea. Though I am willing to bet that there will be an accelerated degradation of cheaper hoses ie: vinyl.
Anybody out there knowledgeable in UV light sources?
