Dana, you going to watch This Is Jinsy?
Peter Serafinowicz (I looked it up) stars in one episode. As do Tennant and Tate. Opinion seems divided but I thought I'd at least have a look, "Has the wit to become a less malevolent League of Gentlemen". Although part of what I love about the League is of course their malevolence... |
Oooooh. How's this managed to pass me by? I've heard the name, but not sure where I've come across it. Having just wikid it, yes I am going to watch it.
Looks damn fine. |

Nanoliters today, oceans tomorrow :D
I think this is something like a gate-keeper, where the voltage only opens and closes the gate to the flow of the (purified) liquid. It's not like reverse osmosis where (larger amounts of) continuous energy is needed to remove the contaminants. |
tha's nanoliters of 25% desalted water.
I can't say how promising this is, but the idea of using energy to move the water and leave the salt behind isn't new, nor difficult to scale up. Just look up, to the clouds. |
You say 25% desalted, I say 75% salted.
Yuck. |
right.
it's a proof of concept, needing dramatic increases in volume and thoroughness before it can produce drinking water (the article itself says that drinking water needs to be 99% desalted. the authors/researchers are confident [of course] that this level "can be reached".) good on them, and good luck. |
Then again there's always the old tin can under the funnel shaped plastic sheet.
How much does sun cost again? Remind me. |
I also vote for the tin can under the plastic sheet with a stone on top to create a funnel effect. Why can't we scale this concept up? We already know it works.
Cost of the sun, let's see ... sorry, foot, I'll have to get back to you on that complicated formula. |
I've placed the order for Apple replace all your iPhones
with the tin cans and the appropriate lengths of string. |
Solar powered desalination stills exist and work. I forget the figures but they're big and produce only small amounts of water. Once built, they pretty much run themselves, apart from changing the water.
|
How about encouraging the boiling of water using vacuum tubes to heat the water? Those fuckers get hot.
