What are the priorities after PS. After the PS with adaquit food, water and shelter attention will turn to rebuilding the infastructure. First could be how to rebuild, or remanufature batteres, generators, water distillers, and outher vital items. Then, how to provide ruditary transportation and commication. Next, putting in place manufaturing of basics and finding raw materals to build or manufature with. With ones attenion constanly on food, watter and shelter we will go no place but backwards to primitive times. The only way to take ones attion off these basics is to sove all of them now for atfter the PS. Anyone of the three not solved and attention will not shift to rebuilding the infastructure of socitiy. Vital to food and clean water production is adquate energy. Energy can take many forms but utamatly must produce food. Water must be to a purity that supports life and not sickness. Shelter needs to be adquate enough to take ones attenion off the weather and alow for rest perods. Adquiate usable energy seems to be the key. Without the sun this becomes chalanging, but not impossable. Energy can be harvested from: 1) Moving mass (water, wind, hand or foot crank generators, ....) 2) Heat diferantals (geothermal(air-ground), volcanic, hot springs,...) 3) Nuclear (half cycle decay, fussion, fission, ...) 4) Chemical reactions [batteres, fule cells, burning anthing (wood, gas, etc), biomass (heat and gas...)] Two quesions: 1) What is missing from this list? 2) What can we do to master number 2 and 3 above? Our discussions of these have been a bit weak in the past.
