According to a new exhibit at Cooper-Hewitt, National Design Museum, of the world’s total population of 6.5 billion, 5.8 billion people, or 90%, have little or no access to most of the products and services many of us take for granted. This exhibit titled “Design for the Other 90% ” explores low-cost solutions for this “other 90%.”
Enclosed are the items that deal with water:
Bamboo Treadle Pump. Over 1.7 million have been sold in Bangladesh and elsewhere, generating $1.4 billion in net farmer income in Bangladesh alone.
Drip Irrigation System. Studies show that drip irrigation reduces water use by 30-70% and increases yields by over 50%.
LifeStraw. It has proven to be effective against waterborne diseases such as typhoid, cholera, dysentery, and diarrhea, and removes particles as small as fifteen microns.
MoneyMaker Hip Pump. On average, users of the Hip Pump have increased their net farm income by over $125, tripling their initial investment of $34 after three or four months.
Pot-in-Pot cooler. It consists of two pots, a smaller earthenware pot nestled within another pot, with the space in between filled with sand and water. When that water evaporates, it pulls heat from the interior of the smaller pot, in which vegetables and fruits can be kept. Pretty Cool, huh
Q Drum. It is a durable container designed to roll easily, and can transport seventy-five liters of clean and potable water. Rolling the water in a cylindrical container, rather than lifting and carrying it, eases the burden of bringing water to those who need it.
Super MoneyMaker Pump. It is a manual treadle pump that will direct water to where it is needed, pulling water from a depth of seven meters and lifting it up fourteen meters above the water source.
Water Storage System. By providing a 10,000-liter plastic storage bag and enclosing it in a hand-dug pit, this system is one-fifth the cost of existing ferro-cement tanks.
