Contemporary systems that exemplify this interplay include green and blue roofs, green façades, living greenwalls, porous pavements, and associated systems for managing water and soil.
They exposed one side of their porous carbon electrode to an electrolyte rich in lithium ions and put a mesh window on the other side of the electrode through which air could be drawn.
Its low density has led scientists to speculate that it may consist of porous, icy material.
With a piece of porous separator material (it looks like white trash-bag plastic) between them, the positive and negative electrodes are sandwiched together into stacks.
According to Gerard Kuiper, of the University of Chicago, the escape of gases from the moon's magma may have given the satellite a light, porous consistency, like that of a pumice stone.
The material also has small spheres of porous silicon embedded in it. Their function is twofold.
Helmand is strategic, lying along the Pakistan border, where the illicit opium trade flourishes and fighters and weapons move easily across the porous border.
The plan is to attempt to store energy in porous sandstone, just like the 1.7 trillion cubic feet of natural gas that lie beneath the surface of the United States.

Transportation would be a non-issue; in a globalized world, borders are porous, particularly in post-conflict states.
A 2007 study by us researchers showed that the system was much more porous than previously thought.
Traditional geothermal plants exploit natural systems in which water seeps down into porous rocks in the ground and emerges back at the surface at a high temperature.
Schrag argues that drilling an escape route for water that has remained trapped in the porous rock for millions of years will help ease the pressure on the rock.
When you see a TV detective turn a doorknob using a handkerchief, she's probably destroying a latent print. The only way not to corrupt a latent print on a non-porous surface is to not touch it.
