If you have 10 minutes, watch this.

wow

this invention is a result of him being angry. gr8 form of tilt.

wow, that's pretty awesome

except that this has been invented before without the pump, which sux cuz it will obv break or clog.

i dont know about just a filter i mean, i am obv not an expert but water treatment plants posses much more steps than this with many chemicals to clean the water, why wouldnt they just filter it like this since it would be much more efficient? maybe its more costly or this is kinda bs?

If what he says is correct, previous methods wouldnt filter well enough to filter out certain viruses. If it works like the guy says it works, this is a pretty nice invention. Too bad it's still 170 GBP, so close to $300. Even though it can of course save lifes and that's worth it, but it's not something you'd buy like "hey, let's do something good for the African people and send them a few of those bottles". It's not like giving away a $80 donkey . For governments and such it's of course well worth considering.

im very impressed.
and it is a step in the right direction even if it fails which i have faith it wont.
the thinking and logic is sound. if they find a way to properly apply it, this could be incredible

someone is still going to have to pay for these things to be manufactured and shipped to these people in need, but its a good idea.

since it only works to filter out 15nm particles (ie. smallest viruses) it still won't filter out much smaller non-biological particles that can still be harmful in drinking water ie. chemical wastes from industrial plants. Still, it's a step in the right direction, and it could be used in a lot of dirty water sources which aren't polluted with chemicals.

thanks for the vid and yeah i was wondering about the chemicals in the water. Why it may not be used in large scale could be that they can't make large enough filters limiting it to hand held bottles
