Being purchased and juiced for model weights is about as noble of an end as any book could hope for.

The vast majority of these 400 heat deaths have nothing to do with the power grid. They are people living outdoors, roofers, elderly, etc. When the temps hit 105+ for long periods there are bound to be people who don't have access to A

They don't boost the feed pressure, just isolate the output permeate line from the back pressure of the storage tank. Instead of the membrane output pushing against the increasing pressure of tank as it fills (decreasing output) it pro

I have built and sold RO systems for 20+ years. It's a weird industry and there are some competing desires in place. In general it's kind of a mess and it's difficult for consumers to navigate. You can build your own system f

The articles state higher levels in bottled water treated with RO but there are many stages of treatment and delivery involved in industrial scale bottled water production. Unclear if RO itself is the underlying cause. RO membranes are tigh

ZeroWater uses a mixed bed ion exchange resin (anion and cation) to attract and hold dissolved ionized solids. Mixed bed resin is very effective and will remove nearly 100% of dissolved solid content which will includes all heavy metals. Th

There can be downsides to the permeate pumps, but not many. Installed with a standard hydraulic shut off valve (ASO) you won't see any issues but you won't get much in the way of improved storage pressure. You will just see improv

I sell residential RO systems. Industry wide the tubing is typically LDPE and the housings/fittings are mostly polypropylene. There is no real practical way to build a residential RO system without using these materials. It's a tr

This is not a consumer product at all. I don't know how useful it will be but it's designed to be development tool for early art direction visualization. Even for 2d visualization it could be very useful if you could drop images i

I think it's actually pretty hard to tell much from the membrane itself, my understanding is that most of the process is based in the membrane preferring the smaller water-only molecules and allowing the waste run off to carry away any

You can remineralize with limestone post-filtration. Or eat food.

I didn't mean that a custom domain is an indicator. Just that they go to the trouble to register throwaways for this use and it isn't limited to just free email services.

I periodically deal with recurring fraud from what seems to be a pretty organized network. - Orders are placed with stolen credentials with correct billing info that matches AVS. - Shipto address are located near billing info, typically in

There are no official treatment recommendations for PFNA, PFOA, PFOS that I know of but they can be treated with activated carbon, RO membranes or some combination. GAC seems to be pretty effective and you could feel pretty safe with a Brit

This is totally correct. It is also not very applicable to drinking water & whole house systems that homeowners are interested in. There are carbon cartridges with ion-exchanges resins blended into the block that seem to be effective fo

You will for sure, I actually like it but not everyone does. You can remineralize and change the taste without too much trouble. I would avoid any other claims made for that process but it does usually improve the taste. Straight RO water i

Carbon filtration will not remove dissolved solids (lead, heavy metals) without added ion-exchange resins. RO is generally the most effective broad spectrum treatment method for drinking water. The mineral issue is pretty much bunk, if the

http://www.kickstarter.com/projects/zioneyez/eyeztm-by-zione... seems like a pretty clear example of this. Backers are actually starting a separate forum to discuss legal action. Doesn't seem to be any sort of recourse via kickstarter.
