To jest zabawne, bo George Carlin miał trochę racji.


Pewne koralowce wolą jeść plastik nawet jeśli nie muszą.

Pojawia się szansa na tańsze pozyskiwanie wody pitnej z mórz. No, to by rozwiązało wszelkie niedobory wody. A gdyby tak rozpraszać z wodociągu wodę w okolicy biegunów? Aby utrzymywać pokrywę lodową na odpowiednim poziomie.

Filtering the salt from seawater can take a lot of energy or specialised engineering. A thin membrane made of porous wood may be able to fix that.

In membrane distillation, salty water is pumped through a film, usually made of some sort of polymer with very narrow pores that filter out the salt and allow only water molecules through. Jason Ren at Princeton University in New Jersey and his colleagues developed a new kind of membrane made of natural wood instead of plastic.

“If you think of traditional water filtration, you need very high-pressure pumping to squeeze the water through, so it uses a lot of energy,” says Ren. “This is more energy efficient and it doesn’t use fossil-fuel based materials like many other membranes for water filtration.”

His team’s membrane is made of a thin piece of American basswood, which undergoes a chemical treatment to strip away extra fibres in the wood and to make its surface slippery to water molecules. One side of the membrane is heated so that when water flows over that side it is vapourised.
