make no mistake about that. Just an idea that I need $40 of coolant every
half a year makes me reject it. Or stick with it's killcoil.

Nuff with the constructive offtopic.

About the rad, seeing enough space between those 'tubes'. Probably low rpm fans optimized at last?
Not a distinctive Feser design. At least wasn't up to this moment.
Here's the original product post:

As far as the source of the pricing, it is based on my initial equipment investment combined with production cost, combined with shipping cost, combined with time. With my most recent order of 40 bottles, I've just now broken even on my initial investment.

The next order after this most recent one will be the first I'll actually make money on, since I originally introduced the product just over a year ago.

The reason I spend two hours a bottle is to push the silver ion concentration to the breaking point, to ensure the longevity of the biocidal properties of the coolant. It is meant to last for a couple years or more, not just half a year.

I could run the coolant through ionization for ten minutes and it would be more than strong enough to sell. I am making sure to reach a point of complete overkill.



When I first introduced this I was very aware that it would be a slow seller, not much profit, and cater to an extremely small niche. For most users, plain distilled and a killcoil makes sense. Some users may prefer using Pure-sil instead, for various reasons.

Anyways, no offense taken, just thought I'd let you know.
