In any case, they have designed it for pressure. The article describes how pressure causes water atoms to line up, train fashion, and move water much much faster than without pressure.
right, the question is -- how much pressure is required? Is it the pressure generated by a 1 cm column of water (as is implied by sieve), or is it the pressure generated by a 1000 watt high pressure pump? The difference will determine whether they have groundbreaking technology or get a participation trophy. From the article it didn't seem like there was any sort of functional prototype.
