Now I’v got it, Pastor Jackson and Representative Neeley of Flint: Interlocking 4×4 plastic collectors fused into the ground with adjustable stakes, each a little higher than the last, with a filter on that lowest one in the center suspended over you funnel and 5 gallon Absopure bottle or your nice clean Home Depot or Ace Hardware five gallon bucket. 6×10,* or sixty square feet is giving me plenty of pristine rainwater to drink here in may, but I want like 6 5 gallon Absopure bottles to store some away for July.
Type 1 plastic, the sort they use for Ocean Spray Cran-Raspberry juice, is my favorite plastic so far. 3-D printers could produce these 4×4 plastic sheets that interlock so as to flow into the one below, making the collector expandable, for one person, a family, a neighborhood or a village. The corner ones flow at the diagonal, the central four at the sides, and the thing could be shaped to fit the yard, with the stakes making the height of each panel adjustable.These could be printed and on the ground in Africa tomorrow. And Hey, when it is not raining, take out the bucket, stake the tapered system close to the ground, and collect evaporating water as the survivalists do. I cannot believe the amount of evaporated water captured under a tarp in the sun, but the plastic too must be safe in the sun. Glass is best, but just too dangerous to work with. I still want to make garden sculpture rain collectors out of stone, all cleanable, with a place to set your bottle underneath!
These are all elaborations of my plastic tarp with a rock in it, ends rolled up in dowels and suspended over a frame, hole just off center over a filter funnel and bottle. Then came sew the filter to the bottom of the tarp, and my nephew says put a hose to connect the filter to the inside of the bottle: then one could ditch the funnel, having just the contoured filter packet on the bottom of the tarp. Yeah!
My Rainwater is pristine, especially compared to our well water. Today I made rainwater ice cubes, and brought in a quart of rain in a juice bottle for the old mum, who drinks the store-bought stuff.
And it the dry season, the 3-D printers could be set to make those triangular insulated people pod bed that are interlocking and expandable, the bed that keeps in the body heat for the homeless, refugees, and people who want to turn down the heat!
*so, 4×4 is only 16 square feet, but 6×10 is 60. Take 3×5=15 sq. ft., add on to one side, subtract one from the other side, one gets not 15 any more but 16? Go figger! But Five 4×4 panels would be 80, and with the diagonals, 8 4×4 sheets go around the one in the center, making 120 (or, 128) square feet of collection surface, with lots of stakes (16)! Oh, I forgot the one in the middle, 144. That is good for 10 gallons in a good rainstorm!
**The problem in Plato’s Meno is the diagonal of a square, an irrational number. So Aristotle teaches that the human things do not admit of the precision of mathematics, but Socrates knows he does not know, and knows where to look, in the question both of geometry and what is virtue.
So, Pastor Jackson and Representative Neeley, we should find entrepreneurs and investors, and make lemonade out of the Flint Water Crisis !
