Your statements seem calculated to dismiss to the reality of food insecurity in the United States without including any relevant factual information. Here you - or any earnest reader - can find the USDA's 2012 report on domestic food security, which is (in contrast) an excellent source of such information.
An estimated 14.5 percent of American households were food insecure at least some time during the year in 2012, meaning they lacked access to enough food for an active, healthy life for all household members. The change from 14.9 percent in 2011 is not considered statistically significant. The prevalence of very low food security was unchanged at 5.7 percent.
Wolfe even anticipated that the material would make folds, wrinkles and creases invisible, just as described in TFS.
I started re-reading The Book of the New Sun last week and there are numerous references to this aspect of cloth of fuligin, the color darker than black.
The first stage is to orbit a cubesat, a tiny, coffee can sized satellite that would contain two highly accurate accelerometers that would go into orbit around Europa and measure its gravity field. In this way the location of Europa's subsurface oceans would be mapped. Indeed it is possible that the probe might find an opening through the ice crust to the ocean, warmed it is thought by tidal forces.
The second stage is to deploy even smaller probes called chipsats, tiny devices that contain sensors, a microchip, and an antenna. Hundreds of these probes, the size of human fingernails, would float down on Europa's atmosphere to be scattered about its surface. While some might be lost, enough will land over a wide enough area to do an extensive chemical analysis of the surface of Europa, which would then be transmitted to the cubesat mothership and then beamed to Earth.
